You can start based off the examples and use it if you run into more errors or you want actual stdlib details. + +Mostly it behaves like JavaScript/TypeScript, with very similar syntax — but BAML is more sound/strict. + +## Best practices and info + +- **LLM function = typed return.** The RETURN TYPE *is* the schema the model must produce (`class`, `enum`, literal union, `string[]`, `T?`). Structured output is just a typed value — hand it to ordinary code. +- **Prompts are backtick strings with `${...}` interpolation.** Write `prompt:` ``… ${arg} …``, and **always inject `${ctx.output_format}`** for a structured return. Escape with `\`` / `\${`; nest with extra backticks. +- **Clients are values, not config blocks.** `client Fast = openai.OpenAiClient.new(model = "…", api_key_env = "OPENAI_API_KEY");` — the old `client Name { provider: …, options: {…} }` block is **removed**. Anything implementing `ai.Client` works (`openai.OpenAiClient`, `anthropic.AnthropicClient`, …; note their `new` params differ — OpenAI takes `api_key_env`/`base_url_env`, Anthropic takes `max_tokens`). **Use `api_key_env = "NAME"`, not `api_key = env.NAME`** — `env.*` is read eagerly at engine init, so one unset var fails the entire project with an opaque `InitFailed(… BamlEnvGet …)` before any test runs; `api_key_env` resolves lazily at call time. Compose reliability by **wrapping**: `ai.clients.Retry.new(inner = c, max_attempts = 3)` and `ai.clients.RoundRobin.new(members = […])` have `.new`, but `ai.clients.Fallback { members: […] }` does **not** — construct it as a class literal. Then `client: Fast` in the function, or the shorthand `client: "openai/gpt-4o-mini"`. `baml describe ai.clients`. +- **Shape the schema with field attributes.** `@description("…")` adds a `///` hint the model sees in `${ctx.output_format}`; `@alias("name")` renames the emitted JSON key. Chain: `tags: string[] @alias("labels") @description("…")`. +- **Test the pure code, not the model.** Unit-test orchestration/post-processing on literal data with `assert.`*. Calling an LLM function in a `test` makes a real request — not an offline test. (`f$parse`/`f$render_prompt`/`f$build_request` exist for debugging.) +- **Build strings with interpolation, not coercion.** ``score=${n}`` stringifies any value (implicit `.to_string()`); call `.to_string()` for the string alone. `+` needs both sides already strings (`"n=" + 5` won't compile). +- `**catch` for some, `catch_all` for all.** `expr catch (e) { baml.errors.ParseError => fallback }` handles a *specific* error; `expr catch_all (e) { _ => fallback }` is *exhaustive* — for a workflow top / entrypoint. Errors propagate implicitly; callers needn't re-declare. **Raise** with `throw baml.errors.InvalidArgument { message: "…" }` (error types are the builtin `baml.errors.*` classes — `InvalidArgument`/`ParseError`/`Io`/`Timeout`/…; `baml describe baml.errors`); annotate a fallible signature with `-> T throws ErrType`. Prefer a typed result **union** (`type R = Ok | Err`) over throwing for ordinary control flow. +- **Interfaces = shared behavior + dynamic dispatch.** `interface I { function m(self) -> T throws never }` (methods may have default bodies); a class opts in via `implements I { … }`; a value typed `I` (or `I[]`) dispatches to the implementor at runtime. Interface methods **must** declare an explicit `throws` clause — `throws never` when the method can't fail, `throws SomeError` when it can (omitting it is an error: *interface method `m` must declare an explicit `throws` clause*). The `implements` block does **not** repeat the clause. +- **Pattern matching.** `match (v) { … }` over values/types; arms are `pattern => expr` — literals, `let x: T` (bind + narrow), class destructure `T { f: let y }`, or-patterns `A | B`, guards `… if cond`, `_`; must be exhaustive. Also `v is T` → bool (narrows) and `if let x: T = v { … } else { … }`. `baml describe patterns`. +- **Concurrency = green threads.** `spawn { … }` returns a `Future`; `await` collects it. Combine many with `baml.future.all` / `all_complete` / `race` / `any` (JS `Promise.*`). Configure a spawn with a `with` clause: `spawn with baml.spawn.options(group = g, cancel = tok, detach = true) { … }` — `baml.spawn.TaskGroup.new(n)` caps concurrency (excess spawns queue FIFO), a `baml.spawn.CancelToken` cancels cooperatively. `baml describe spawn` / `baml describe baml.future`. +- **Resource safety — `defer`, `cleanup`, `catch (e, ctx)`.** `defer { … }` runs a block at scope exit, LIFO, on *every* path (return / throw / fall-through) — like Go. A class method named `function cleanup(self) -> void` is a **finalizer**: it runs at most once per instance whether you call it, `defer` it, or the GC reclaims it. `catch (e, ctx)` binds an **`ErrorContext`** alongside the error — an error thrown while handling another chains onto it, so `ctx.root_cause()` / `ctx.cause` walk back to the original failure and `ctx.to_string()` renders the whole chain (Python `__context__`-style). `while let PATTERN = expr { … }` loops until the pattern fails (e.g. draining a `T?`-returning `.pop()`). +- **Call BAML from Python / TS.** Declare a `[generator.]` in `baml.toml`, run `baml generate`, then import the typed `baml_sdk`. Install + usage: `baml describe python` / `baml describe typescript` / `baml describe baml_sdk`. +- **Safe access over indexing.** Subscript panics on a missing index/key; use `.at(i)`/`.get(k)` (→ `T?`), reach through with `?.`, default with `??` (parenthesize: `(m.get(k) ?? 0) + 1`). +- **Stdlib methods are snake_case, called on a value.** Some return new, some mutate in place, a few do both (`sort_by_key` sorts the receiver *and* returns it) — to read the docs, `baml describe `. +- **Class fields `name: type,`; construct `Type { field: val }`.** Methods take a bare `self`; factories are free functions. **Fields are mutable** (like TS): `obj.field = v` and `obj.field += n` work, and a `self` method can mutate in place — a side-effect method returns `void`. **Classes are reference types**: `find`/`at(i)`/subscript return a *live alias*, not a copy, so mutating the result mutates that element inside the array (`xs.find(p)?.n += 1` updates `xs`), and a class passed to a function can be mutated by the callee. **Avoid struct-update spread for now** — reconstruct or mutate instead. `User { ...u, tier: Tier.Free }` compiles and runs, but `baml fmt` **rejects** it (`found SPREAD_ELEMENT`), so a file using it can't be formatted; prefer the explicit form until that lands. **Empty classes are legal** (`class Marker {}`) — handy as union variants. **Enums are plain variants — no methods, no associated data** (`E.A.foo()` won't compile); put behavior in free functions that `match`. `enum E { A, B }`, access `E.A`. +- **Blocks are expressions** — last expression is the value (no `;`); `return x;` for early exit. A side-effect-only function's return type is `-> null` (canonical — `baml describe void`; `-> void` also works); its block's unit *value* is just bare `null` (writing `-> null` in *value* position is a parse error). `for (let x in xs)` iterates VALUES; `while (cond) { … }` loops. Closures `(x) -> { ... }` infer param/return from context (annotate `(x: T) -> R` only when ambiguous; the `->` is required). `.map`/`.filter` return arrays directly (no `.collect()`). Empty map needs a type: `let m: map = {};`. +- **No ternary — `if/else` is the expression.** There's no `cond ? a : b`; `if (cond) { a } else { b }` *is* an expression that returns a value, so assign it directly: `let label = if (x > 3) { "big" } else { "small" };`. Each branch is a block whose last expression is its value (no `return`). Chain with `else if`, and pair with `if let PATTERN = expr { … } else { … }` for bind-and-narrow. +- **Arrays have a JS-like method set** — `map`/`filter`/`filter_map`/`reduce`/`find`/`some`/`every`/`flat_map`/`slice`/`concat`/`join`/`includes`/length(), plus in-place `push`/`pop`/`shift`/`unshift`/`sort_by`/`sort_by_key`. Most take closures that can `throws`. `baml describe Array` gives more info. +- Local let bindings are reassignable (x = x + 1) — no mut keyword (it's TS let, not Rust); there's no const either. +- **Args: defaults with `=`, keyword calls with `=` (never `:`).** Declare a default in the signature: `function f(a: int, b: int = 10)`; call `f(1)` or `f(1, b = 2)`. A **defaulted param must be passed by name** — `f(1, 2)` is an error (`defaulted parameter 'b' must be passed by name`). Any param (even required) may be passed by name (`f(a = 1, b = 2)`), and you can skip a middle default to set a later one (`f(1, c = 9)`). Keyword syntax is `name = value`; `name: value` won't parse (`:` is for types/fields). **`T?` does NOT make an argument optional** — unlike TS `b?: T`, a `b: T?` param is still *required* (you must pass `null`, else `expected N argument(s), got …`); add `= null` to make it omittable. Built-ins follow this: `baml.http.fetch(url, timeout = baml.time.Duration.from_seconds(10))`. +- **Where it diverges from TS (the silent traps):** arithmetic is *type-driven*, not TS-style. `int / int` is **truncating integer division** (`285 / 100 == 2`, NOT `2.85`) and `%` is the remainder (`285 % 100 == 85`); this compiles fine and just gives a quietly-wrong number, so it's the highest-value gotcha. Mix in a float to get float division (`285 / 100.0 == 2.85`, `285.0 / 100 == 2.85`); any mixed `int`/`float` op promotes to `float` (`5 + 2.0 == 7.0`). There is **no `.to_float()`** — convert an int with `n * 1.0` (or divide by a float). An `int` result does **not** auto-coerce to `float` on assignment (`let x: float = 285 / 100` is a compile error). `+` is **numeric-only**: string concat needs both sides already `string` (`"n=" + 5` won't compile — use `${...}` interpolation). Comparisons (`==`, `<`, …, structural `==`) and `&&`/`||`/`!` are TS-like. +- **Tests:** lone `test "name" { ... }` (no wrapper); `testset` only GROUPS. Asserts (only 5): `assert.equal`/`approx_equal`/`is_true`/`not_null`/`contains`. `assert.equal` compares **structurally** (deep, across classes/arrays/maps) — and so does plain `==`, which is the bool form. `assert.equal` is *exact* on floats; use `assert.approx_equal(actual, expected, eps)` for computed ones. Last assert: no trailing `;`. Run one: `baml test -i "Testset::TestName"` (`-x` to exclude) — the selector keys on `testset::test`, so a top-level `test` with no testset is `-i "::TestName"`; `baml test --list` prints valid selectors. +- **Namespaces =** `ns_*` **directories, no imports.** A folder `ns_/` under `baml_src/` puts its files in namespace ``; files in `baml_src/` itself are the `root` namespace (nesting stacks — `ns_a/ns_b/` → `root.a.b`; non`ns_` folders don't namespace). Same namespace = same scope: files share definitions with no import. To reach *another* namespace, use the **absolute** path `root..` `root.llm.Response`) — a bare `Response` from outside is rejected `did you mean root.Response?`). Run a target by its namespace-relative path `baml run agent.main`), but `baml run -e` evaluates in the root scope, so reach in with the absolute form: `baml run -e 'root.agent.main()'`. It's more idiomatic to keep namespaces as flat as possible, like Go packages. +- Run `baml fmt` when you're done with a feature. +- BAML functions/methods/types etc are accessible from other languages (python, typescript). Run `baml describe baml_sdk` for setup instructions. You might want to see if the current dir is near a python or TS project to setup the wiring for the user. The baml.toml toolchain version must match the installed python/ts baml package. Keep AI-related things and workflow logic in BAML as much as possible. +- BAML has `log.info(..)` or `log.debug(..)` +- `baml pack` can create a binary. +- Use backtics instead of \#" "# like baml used to have. + + +For anything not shown (signatures, niche stdlib, advanced features), run `**baml describe `** — the CLI is the docs; never guess the stdlib. + +## Example 1 — LLM DSL + glue (schema, attributes, client, backtick prompt, post-processing) + +```baml +// The return type IS the schema; @description/@alias shape what the model sees. +enum Priority { High, Low } + +class LineItem { + name: string, + amount: float, + priority: Priority, +} + +class Invoice { + vendor: string @alias("seller"), + status: "draft" | "final" @description("invoice state"), + items: LineItem[], + note: string?, +} + +// Clients are ordinary VALUES implementing `ai.Client` (no `client { }` config block). +// Prefer `api_key_env = "NAME"` (resolved lazily) over `api_key = env.NAME` — the latter is +// read at engine init, so an unset var fails the WHOLE project, even offline tests. +client Fast = openai.OpenAiClient.new(model = "gpt-4o-mini", api_key_env = "OPENAI_API_KEY"); +// Compose reliability by WRAPPING a client. `Retry`/`RoundRobin` have `.new(...)`; +// `Fallback` has no `.new`, so construct it as a class literal. +client Reliable = ai.clients.Retry.new(inner = Fast, max_attempts = 3); +client Safe = ai.clients.Fallback { members: [Reliable, anthropic.AnthropicClient.new(model = "claude-sonnet-5")] }; + +function Extract(raw: string) -> Invoice { + client: Reliable // or shorthand: "openai/gpt-4o-mini" + prompt: `Extract the invoice. ${ctx.output_format}\n${raw}` +} + +// Structured output is just a typed value — hand it to ordinary code. +// Closure params/return infer from context; only the -> is required. +// `min_amount` has a default — omit it, or pass it BY NAME (`min_amount = …`). +function high_total(inv: Invoice, min_amount: float = 0.0) -> float { + inv.items + .filter((i) -> { i.priority == Priority.High && i.amount >= min_amount }) + .reduce((a, i) -> { a + i.amount }, 0.0) +} + +test "post-process a literal Invoice — no model call" { + let inv = Invoice { + vendor: "Acme", status: "final", note: null, + items: [LineItem { name: "srv", amount: 900.0, priority: Priority.High }, + LineItem { name: "mug", amount: 12.0, priority: Priority.Low }], + }; + assert.equal(high_total(inv), 900.0); // default min_amount = 0.0 + assert.equal(high_total(inv, min_amount = 1000.0), 0.0) // keyword arg +} +``` + +## Example 2 — the language (methods, interpolation, closures, maps, json, errors).

Structured output is just a typed value — hand it to ordinary code. +- **Prompts are backtick strings with `${...}` interpolation.** Write `prompt:` ``… ${arg} …``, and **always inject `${ctx.output_format}`** for a structured return. Escape with `\`` / `\${`; nest with extra backticks. +- **Clients are values, not config blocks.** `client Fast = openai.OpenAiClient.new(model = "…", api_key_env = "OPENAI_API_KEY");` — the old `client Name { provider: …, options: {…} }` block is **removed**. Anything implementing `ai.Client` works (`openai.OpenAiClient`, `anthropic.AnthropicClient`, …; note their `new` params differ — OpenAI takes `api_key_env`/`base_url_env`, Anthropic takes `max_tokens`). **Use `api_key_env = "NAME"`, not `api_key = env.NAME`** — `env.*` is read eagerly at engine init, so one unset var fails the entire project with an opaque `InitFailed(… BamlEnvGet …)` before any test runs; `api_key_env` resolves lazily at call time. Compose reliability by **wrapping**: `ai.clients.Retry.new(inner = c, max_attempts = 3)` and `ai.clients.RoundRobin.new(members = […])` have `.new`, but `ai.clients.Fallback { members: […] }` does **not** — construct it as a class literal. Then `client: Fast` in the function, or the shorthand `client: "openai/gpt-4o-mini"`. `baml describe ai.clients`. +- **Shape the schema with field attributes.** `@description("…")` adds a `///` hint the model sees in `${ctx.output_format}`; `@alias("name")` renames the emitted JSON key. Chain: `tags: string[] @alias("labels") @description("…")`. +- **Test the pure code, not the model.** Unit-test orchestration/post-processing on literal data with `assert.`*. Calling an LLM function in a `test` makes a real request — not an offline test. (`f$parse`/`f$render_prompt`/`f$build_request` exist for debugging.) +- **Build strings with interpolation, not coercion.** ``score=${n}`` stringifies any value (implicit `.to_string()`); call `.to_string()` for the string alone. `+` needs both sides already strings (`"n=" + 5` won't compile). +- `**catch` for some, `catch_all` for all.** `expr catch (e) { baml.errors.ParseError => fallback }` handles a *specific* error; `expr catch_all (e) { _ => fallback }` is *exhaustive* — for a workflow top / entrypoint. Errors propagate implicitly; callers needn't re-declare. **Raise** with `throw baml.errors.InvalidArgument { message: "…" }` (error types are the builtin `baml.errors.*` classes — `InvalidArgument`/`ParseError`/`Io`/`Timeout`/…; `baml describe baml.errors`); annotate a fallible signature with `-> T throws ErrType`. Prefer a typed result **union** (`type R = Ok | Err`) over throwing for ordinary control flow. +- **Interfaces = shared behavior + dynamic dispatch.** `interface I { function m(self) -> T throws never }` (methods may have default bodies); a class opts in via `implements I { … }`; a value typed `I` (or `I[]`) dispatches to the implementor at runtime. Interface methods **must** declare an explicit `throws` clause — `throws never` when the method can't fail, `throws SomeError` when it can (omitting it is an error: *interface method `m` must declare an explicit `throws` clause*). The `implements` block does **not** repeat the clause. +- **Pattern matching.** `match (v) { … }` over values/types; arms are `pattern => expr` — literals, `let x: T` (bind + narrow), class destructure `T { f: let y }`, or-patterns `A | B`, guards `… if cond`, `_`; must be exhaustive. Also `v is T` → bool (narrows) and `if let x: T = v { … } else { … }`. `baml describe patterns`. +- **Concurrency = green threads.** `spawn { … }` returns a `Future`; `await` collects it. Combine many with `baml.future.all` / `all_complete` / `race` / `any` (JS `Promise.*`). Configure a spawn with a `with` clause: `spawn with baml.spawn.options(group = g, cancel = tok, detach = true) { … }` — `baml.spawn.TaskGroup.new(n)` caps concurrency (excess spawns queue FIFO), a `baml.spawn.CancelToken` cancels cooperatively. `baml describe spawn` / `baml describe baml.future`. +- **Resource safety — `defer`, `cleanup`, `catch (e, ctx)`.** `defer { … }` runs a block at scope exit, LIFO, on *every* path (return / throw / fall-through) — like Go. A class method named `function cleanup(self) -> void` is a **finalizer**: it runs at most once per instance whether you call it, `defer` it, or the GC reclaims it. `catch (e, ctx)` binds an **`ErrorContext`** alongside the error — an error thrown while handling another chains onto it, so `ctx.root_cause()` / `ctx.cause` walk back to the original failure and `ctx.to_string()` renders the whole chain (Python `__context__`-style). `while let PATTERN = expr { … }` loops until the pattern fails (e.g. draining a `T?`-returning `.pop()`). +- **Call BAML from Python / TS.** Declare a `[generator.]` in `baml.toml`, run `baml generate`, then import the typed `baml_sdk`. Install + usage: `baml describe python` / `baml describe typescript` / `baml describe baml_sdk`. +- **Safe access over indexing.** Subscript panics on a missing index/key; use `.at(i)`/`.get(k)` (→ `T?`), reach through with `?.`, default with `??` (parenthesize: `(m.get(k) ?? 0) + 1`). +- **Stdlib methods are snake_case, called on a value.** Some return new, some mutate in place, a few do both (`sort_by_key` sorts the receiver *and* returns it) — to read the docs, `baml describe `. +- **Class fields `name: type,`; construct `Type { field: val }`.** Methods take a bare `self`; factories are free functions. **Fields are mutable** (like TS): `obj.field = v` and `obj.field += n` work, and a `self` method can mutate in place — a side-effect method returns `void`. **Classes are reference types**: `find`/`at(i)`/subscript return a *live alias*, not a copy, so mutating the result mutates that element inside the array (`xs.find(p)?.n += 1` updates `xs`), and a class passed to a function can be mutated by the callee. **Avoid struct-update spread for now** — reconstruct or mutate instead. `User { ...u, tier: Tier.Free }` compiles and runs, but `baml fmt` **rejects** it (`found SPREAD_ELEMENT`), so a file using it can't be formatted; prefer the explicit form until that lands. **Empty classes are legal** (`class Marker {}`) — handy as union variants. **Enums are plain variants — no methods, no associated data** (`E.A.foo()` won't compile); put behavior in free functions that `match`. `enum E { A, B }`, access `E.A`. +- **Blocks are expressions** — last expression is the value (no `;`); `return x;` for early exit. A side-effect-only function's return type is `-> null` (canonical — `baml describe void`; `-> void` also works); its block's unit *value* is just bare `null` (writing `-> null` in *value* position is a parse error). `for (let x in xs)` iterates VALUES; `while (cond) { … }` loops. Closures `(x) -> { ... }` infer param/return from context (annotate `(x: T) -> R` only when ambiguous; the `->` is required). `.map`/`.filter` return arrays directly (no `.collect()`). Empty map needs a type: `let m: map = {};`. +- **No ternary — `if/else` is the expression.** There's no `cond ? a : b`; `if (cond) { a } else { b }` *is* an expression that returns a value, so assign it directly: `let label = if (x > 3) { "big" } else { "small" };`. Each branch is a block whose last expression is its value (no `return`). Chain with `else if`, and pair with `if let PATTERN = expr { … } else { … }` for bind-and-narrow. +- **Arrays have a JS-like method set** — `map`/`filter`/`filter_map`/`reduce`/`find`/`some`/`every`/`flat_map`/`slice`/`concat`/`join`/`includes`/length(), plus in-place `push`/`pop`/`shift`/`unshift`/`sort_by`/`sort_by_key`. Most take closures that can `throws`. `baml describe Array` gives more info. +- Local let bindings are reassignable (x = x + 1) — no mut keyword (it's TS let, not Rust); there's no const either. +- **Args: defaults with `=`, keyword calls with `=` (never `:`).** Declare a default in the signature: `function f(a: int, b: int = 10)`; call `f(1)` or `f(1, b = 2)`. A **defaulted param must be passed by name** — `f(1, 2)` is an error (`defaulted parameter 'b' must be passed by name`). Any param (even required) may be passed by name (`f(a = 1, b = 2)`), and you can skip a middle default to set a later one (`f(1, c = 9)`). Keyword syntax is `name = value`; `name: value` won't parse (`:` is for types/fields). **`T?` does NOT make an argument optional** — unlike TS `b?: T`, a `b: T?` param is still *required* (you must pass `null`, else `expected N argument(s), got …`); add `= null` to make it omittable. Built-ins follow this: `baml.http.fetch(url, timeout = baml.time.Duration.from_seconds(10))`. +- **Where it diverges from TS (the silent traps):** arithmetic is *type-driven*, not TS-style. `int / int` is **truncating integer division** (`285 / 100 == 2`, NOT `2.85`) and `%` is the remainder (`285 % 100 == 85`); this compiles fine and just gives a quietly-wrong number, so it's the highest-value gotcha. Mix in a float to get float division (`285 / 100.0 == 2.85`, `285.0 / 100 == 2.85`); any mixed `int`/`float` op promotes to `float` (`5 + 2.0 == 7.0`). There is **no `.to_float()`** — convert an int with `n * 1.0` (or divide by a float). An `int` result does **not** auto-coerce to `float` on assignment (`let x: float = 285 / 100` is a compile error). `+` is **numeric-only**: string concat needs both sides already `string` (`"n=" + 5` won't compile — use `${...}` interpolation). Comparisons (`==`, `<`, …, structural `==`) and `&&`/`||`/`!` are TS-like. +- **Tests:** lone `test "name" { ... }` (no wrapper); `testset` only GROUPS. Asserts (only 5): `assert.equal`/`approx_equal`/`is_true`/`not_null`/`contains`. `assert.equal` compares **structurally** (deep, across classes/arrays/maps) — and so does plain `==`, which is the bool form. `assert.equal` is *exact* on floats; use `assert.approx_equal(actual, expected, eps)` for computed ones. Last assert: no trailing `;`. Run one: `baml test -i "Testset::TestName"` (`-x` to exclude) — the selector keys on `testset::test`, so a top-level `test` with no testset is `-i "::TestName"`; `baml test --list` prints valid selectors. +- **Namespaces =** `ns_*` **directories, no imports.** A folder `ns_/` under `baml_src/` puts its files in namespace ``; files in `baml_src/` itself are the `root` namespace (nesting stacks — `ns_a/ns_b/` → `root.a.b`; non`ns_` folders don't namespace). Same namespace = same scope: files share definitions with no import. To reach *another* namespace, use the **absolute** path `root..` `root.llm.Response`) — a bare `Response` from outside is rejected `did you mean root.Response?`). Run a target by its namespace-relative path `baml run agent.main`), but `baml run -e` evaluates in the root scope, so reach in with the absolute form: `baml run -e 'root.agent.main()'`. It's more idiomatic to keep namespaces as flat as possible, like Go packages. +- Run `baml fmt` when you're done with a feature. +- BAML functions/methods/types etc are accessible from other languages (python, typescript). Run `baml describe baml_sdk` for setup instructions. You might want to see if the current dir is near a python or TS project to setup the wiring for the user. The baml.toml toolchain version must match the installed python/ts baml package. Keep AI-related things and workflow logic in BAML as much as possible. +- BAML has `log.info(..)` or `log.debug(..)` +- `baml pack` can create a binary. +- Use backtics instead of \#" "# like baml used to have. + + +For anything not shown (signatures, niche stdlib, advanced features), run `**baml describe `** — the CLI is the docs; never guess the stdlib. + +## Example 1 — LLM DSL + glue (schema, attributes, client, backtick prompt, post-processing) + +```baml +// The return type IS the schema; @description/@alias shape what the model sees. +enum Priority { High, Low } + +class LineItem { + name: string, + amount: float, + priority: Priority, +} + +class Invoice { + vendor: string @alias("seller"), + status: "draft" | "final" @description("invoice state"), + items: LineItem[], + note: string?, +} + +// Clients are ordinary VALUES implementing `ai.Client` (no `client { }` config block). +// Prefer `api_key_env = "NAME"` (resolved lazily) over `api_key = env.NAME` — the latter is +// read at engine init, so an unset var fails the WHOLE project, even offline tests. +client Fast = openai.OpenAiClient.new(model = "gpt-4o-mini", api_key_env = "OPENAI_API_KEY"); +// Compose reliability by WRAPPING a client. `Retry`/`RoundRobin` have `.new(...)`; +// `Fallback` has no `.new`, so construct it as a class literal. +client Reliable = ai.clients.Retry.new(inner = Fast, max_attempts = 3); +client Safe = ai.clients.Fallback { members: [Reliable, anthropic.AnthropicClient.new(model = "claude-sonnet-5")] }; + +function Extract(raw: string) -> Invoice { + client: Reliable // or shorthand: "openai/gpt-4o-mini" + prompt: `Extract the invoice. ${ctx.output_format}\n${raw}` +} + +// Structured output is just a typed value — hand it to ordinary code. +// Closure params/return infer from context; only the -> is required. +// `min_amount` has a default — omit it, or pass it BY NAME (`min_amount = …`). +function high_total(inv: Invoice, min_amount: float = 0.0) -> float { + inv.items + .filter((i) -> { i.priority == Priority.High && i.amount >= min_amount }) + .reduce((a, i) -> { a + i.amount }, 0.0) +} + +test "post-process a literal Invoice — no model call" { + let inv = Invoice { + vendor: "Acme", status: "final", note: null, + items: [LineItem { name: "srv", amount: 900.0, priority: Priority.High }, + LineItem { name: "mug", amount: 12.0, priority: Priority.Low }], + }; + assert.equal(high_total(inv), 900.0); // default min_amount = 0.0 + assert.equal(high_total(inv, min_amount = 1000.0), 0.0) // keyword arg +} +``` + +## Example 2 — the language (methods, interpolation, closures, maps, json, errors).

Treat it like the - ONNX/CUDA shared libraries allowed by the packaging decision, and make the - installer acquire it so normal runtime does not depend on a network request. -- The generated bridge was exercised from the native `lw` process. Its first - invocation downloaded and verified BAML 0.16.0's - `libbaml_cffi-x86_64-unknown-linux-gnu.so`; later calls reused the cache. - BAML emits local structured runtime logs without extra application code. -- BAML also writes ignored structured profiles under `.baml/profiles/` during - ordinary SDK calls. This is the advertised local tracing behavior, so no - separate trace code was added. -- Python and NeMo are allowed for one-time model conversion or preparation. - They must not be required to build, install, or run the final application. - -## Hard feasibility gate - -Before expanding the rewrite, prove that the exact Parakeet v3 model can perform -correct native CUDA inference on this machine. The initial `nvidia-smi` probe -reported an NVML driver/library mismatch. The running kernel module is -`610.43.03`, while installed NVIDIA userspace is `610.57.04`; a reboot is likely -needed before the CUDA gate can pass. Do not substitute CPU inference and -continue as though the gate passed. - -The strict probe loaded the verified FP16 model files far enough to initialize -the CUDA provider, then failed at `cudaSetDevice` with CUDA error 803: -"system has unsupported display driver / cuda driver combination." This -confirms the version mismatch is the current hard blocker. Reboot before the -next probe so the running kernel module matches installed userspace. - -After reboot, both the kernel module and userspace reported `610.57.04`. The -strict CUDA probe then passed with the canonical FP16 export: model load took -1.38 seconds and an 11.04-second fixture transcribed in 645 ms with the expected -sentence. Native CUDA inference is feasible on this machine. - -ONNX Runtime requires cuDNN 9. The current Python environment contains the -native cuDNN libraries, and a cache-local `libcudnn.so` alias proved they work. -The installer now resolves the current signed Manjaro `cudnn` package through -pacman, verifies its detached signature with the system keyring, and extracts -the libraries under `~/.local/lib/local-wisper` when cuDNN 9 is not installed -system-wide. The executable preloads that directory before initializing CUDA. - -ONNX Runtime's static build also resolved provider libraries beside the T3 Code -AppImage during the probe. Temporary symlinks proved provider discovery, then -were removed. The final package needs an explicit provider-library location -rather than relying on that environment-specific lookup. - -The native inference candidate is `parakeet-rs` 0.3.7 with ONNX Runtime's CUDA -execution provider. A canonical FP16 export of the exact v3 model is available -from `ysdede/parakeet-tdt-0.6b-v3-onnx` with the encoder, decoder/joint graph, -vocabulary, and preprocessing graph expected by the Rust decoder. - -The native model host holds an exclusive per-user file lock before BAML touches -model assets or binds its loopback server. This makes the one-model rule -structural: racing clients can start processes, but only the lock owner can load -CUDA state. The host serializes inference and keeps that one model warm. - -Automatic selection uses a real system check rather than a user-facing model -choice. An NVIDIA device selects the pinned FP16 export. With no NVIDIA device, -or when CUDA model initialization fails, the same daemon process loads the -pinned INT8 export on ONNX Runtime's CPU provider. The legacy `--device cuda` -input follows this automatic behavior so an unchanged Sway wrapper also works -on a CPU-only machine. `--device cpu` remains as a hidden test and compatibility -override. - -The CPU feasibility test used the repository's INT8 encoder and decoder at the -same pinned revision as FP16. Checksums matched. The model loaded in 1.75 -seconds, used about 1 GB resident memory, and transcribed the 11.04-second -fixture in 803 ms. Its raw result added a few filler tokens compared with FP16, -but preserved the sentence. With CUDA visible, automatic mode selected FP16, -loaded in 1.36 seconds, and transcribed the fixture in 363 ms. With -`nvidia-smi` hidden, automatic mode selected INT8 CPU and made no GPU -allocation. - -The first implementation made Rust interpret a static action list returned by -BAML. That was the wrong boundary for this experiment: it made Rust own the -state machine and turned BAML into workflow metadata. The application now calls -one BAML `run_app` entrypoint. BAML parses the unchanged Sway invocation, owns -the command state and ordering, and invokes typed native closures supplied by -the Rust bootstrap. The generated Rust bridge supports this direction directly. -Five concurrent `preload` calls were previously tested against one resident -Rust process and one CUDA allocation. - -The final boundary keeps Rust as a small owner of the live `ParakeetTDT` object, -CUDA/ONNX setup, a per-user OS lock, and Linux process operations BAML cannot -express safely. Application policy and orchestration live in BAML; line count -is only a useful signal of that ownership. - -BAML now also owns recorder selection, session paths, persisted Sway state, -interactive recording, start/stop/cancel behavior, audio validation, and -cleanup. The native recorder callback is limited to spawning and signalling a -Linux process. Persisted process identities contain both PID and `/proc` start -time, preventing stale state from signalling an unrelated process after PID -reuse. - -BAML now owns the resident-service protocol and model preparation as well. It -selects FP16 CUDA or INT8 CPU, downloads and verifies the pinned assets, manages -daemon readiness and request deadlines, and serves authenticated HTTP on an -ephemeral loopback port. Rust retains the live `ParakeetTDT`, the canonical -per-user file lock, cuDNN/ONNX setup, detached process creation, and recorder -signals. The runtime directory is derived from the numeric user ID rather than -configuration, so changing `XDG_RUNTIME_DIR` cannot bypass the one-model lock -on a normal Linux user session. - -The new BAML service completed a controlled live handoff on this machine. It -loaded FP16 on CUDA, exposed `127.0.0.1:42057` with a per-process token, and -transcribed the 11.04-second fixture correctly. The process held one 2.34 GB -GPU allocation. The test daemon was then stopped and the installed daemon was -restored. A simultaneous probe while the installed daemon was resident exited -before model initialization, confirming the shared OS lock prevents a second -copy across the old and new service protocols. - -The BAML-owned CPU path also completed the same handoff and fixture request. It -loaded the pinned INT8 export at roughly 1.14 GB RSS, returned the expected -sentence with the known extra filler tokens, and made no CUDA allocation. The -installed automatic/CUDA daemon was restored afterward. - -BAML now implements deterministic cleanup without regular expressions using a -typed character scanner. It owns spoken-number normalization, glossary parsing, -boundary-aware non-cascading `[always]` rules, statement style, language-drift -protection, the six-word decision, the complete `gpt-5.6-luna` prompt, and the -timeout race. BAML tests cover the migrated behavior. A one-second -`sway-start`/`sway-stop` capture also completed through the earlier workflow; -the empty recording correctly reported no speech. - -Model assets are pinned to Hugging Face revision -`f88260fa0777fe0868dda6df85d1a98f012a4a7a`. The cache records exact sizes and -SHA-256 digests for the encoder, decoder/joint graph, and vocabulary. Downloads -land in `.part` files and are renamed only after verification. A completion -marker lets later daemon starts avoid hashing the 1.2 GB encoder again. - -The optimized `lw` binary is 29 MB and links only the ordinary glibc, libstdc++, -libgcc, and libm runtime libraries at startup. A release build loaded cuDNN from -an explicit native-library directory with `LD_LIBRARY_PATH` removed, then -loaded Parakeet on CUDA in 1.33 seconds. It transcribed the 11.04-second fixture -correctly in 249 ms. The installer was run against the live user prefix after -explicit approval.

Provider libraries are committed first and the executable is moved into -place last, so a failed copy cannot truncate the working installation. - -## Current system integration - -- Sway invokes `preload`, `sway-start`, `sway-stop`, and `sway-cancel`. -- Current environment values: - - backend: `parakeet` - - model format: selected automatically - - device: automatic; the retained `cuda` compatibility value also falls back - to CPU - - VAD: `false` - - output mode: `type` - - post-process model: `gpt-5.6-luna` - - post-process timeout: `20` - - glossary: `~/.config/local-wisper/glossary.txt` - -## Working rules - -- Make atomic commits at meaningful milestones. -- Keep this file updated when a decision or feasibility finding changes the - implementation. -- The system installation now points at this worktree's native build.
