Andi AIRun

Run AI prompts like programs. Executable markdown with shebang, Unix pipes, and output redirection. Supports multiple runtimes (Claude Code, Codex CLI) with cross-cloud provider switching and any-model support — free local or 100+ cloud models.

# Claude Code: any model or provider
ai                                        # Regular Claude subscription (Pro, Max)
ai --aws --opus --team --resume           # Resume chats on AWS w/ Opus 4.7 + Agent Teams
ai --ollama --bypass --model qwen3-coder  # Ollama local model with bypassPermissions set

# Codex CLI: OpenAI's coding agent
ai --codex                                # Codex with gpt-5.4 (default)
ai --codex --high                         # Codex with gpt-5.4 (flagship)
ai --codex --ollama                       # Codex with local Ollama models

# Run prompts like programs (works with any runtime)
ai --azure --haiku script.md
ai --codex script.md

# Script automation
cat data.json | ./analyze.md > results.txt

Choose your runtime — Claude Code or Codex CLI — and switch between clouds + models: AWS Bedrock, Google Vertex, Azure, Vercel, Anthropic API, OpenAI API. Supports free local models (Ollama, LM Studio) and 100+ alternate cloud models via Vercel AI Gateway or Ollama Cloud. Swap and resume conversations mid-task to avoid rate limits and keep working.

What it does:

Multiple runtimes: Claude Code and Codex CLI with a single ai command (--cc, --codex)
Executable markdown with #!/usr/bin/env ai shebang for script automation
Unix pipe support: pipe data into scripts, redirect output, chain in pipelines
Cross-cloud provider switching: use Claude on AWS, Vertex, Azure, Anthropic API, or Codex on OpenAI, Azure OpenAI, OpenRouter + switch mid-conversation to bypass rate limits
Model tiers: --opus/--high, --sonnet/--mid, --haiku/--low — maps to each runtime's models
Cross-interpreter effort control: --effort low|medium|high|max
Session continuity: --resume picks up your previous chats with any model/provider
Non-destructive: plain claude and codex always work untouched as before

From Andi AI Search. Star this repo if it helps!

Latest: Opus 4.7 default across all providers. Codex CLI support (--codex), cross-interpreter effort levels (--effort), tool profiles (--profile). Script variables, live streaming, Agent Teams, local models (Ollama, LM Studio), persistent defaults, 100+ cloud models via Vercel. See CHANGELOG.md.

Quick Start

Supported Platforms:

macOS 13.0+
Linux (Ubuntu 20.04+, Debian 10+)
Windows 10+ via WSL

Prerequisites: At least one runtime installed — Claude Code or Codex CLI

# Install a runtime (one or both)
curl -fsSL https://claude.ai/install.sh | bash   # Claude Code (Anthropic)
npm install -g @openai/codex                      # Codex CLI (OpenAI)

# Install Andi AIRun
git clone https://github.com/andisearch/airun.git
cd airun && ./setup.sh

You can now run any markdown file as an AI script:

# Create an executable prompt
cat > task.md << 'EOF'
#!/usr/bin/env ai
Analyze my codebase and summarize the architecture.
EOF

chmod +x task.md
./task.md                         # Runs with your Claude subscription

Or run any markdown file directly:

ai task.md

Pipe data and redirect output (Unix-style automation):

cat data.json | ./analyze.md > results.txt    # Pipe in, redirect out
git log -10 | ./summarize.md                  # Feed git history to AI
./generate.md | ./review.md > final.txt       # Chain scripts together

Run scripts from the web (installmd.org support):

curl -fsSL https://andisearch.github.io/ai-scripts/analyze.md | ai
echo "Explain what a Makefile does" | ai         # Simple prompt

Minimal alternative: If you just want basic executable markdown without installing this repo, add a ai script to your PATH:

#!/bin/bash
claude -p "$(tail -n +2 "$1")"

This works for simple prompts but lacks provider switching, model selection, stdin piping, output formats, and session isolation. (credit: apf6)

Commands

Command	Description
`ai` / `airun`	Universal entry point - run scripts, switch providers
`ai update`	Update AI Runner to the latest version
`ai-sessions`	View active AI coding sessions
`ai-status`	Show current configuration and provider status

Running ai with no flags matches your claude defaults — if you're logged in with a subscription, ai uses it. Your environment is automatically restored on exit. Add provider flags to switch, or use ai --aws --opus --set-default to save your preferred provider and model for future runs.

Usage Examples

# Run a markdown script (auto-detects runtime + provider)

# Live output + file redirect (narration to console, clean content to file)
./live-report.md > report.md

# Override script variables (--topic, --style match declared vars: names)
./summarize-topic.md --live --topic "the fall of rome" --style "peter griffin"

# Resume last conversation
ai --aws --resume

# Save runtime + provider + model as default
ai --codex --high --set-default   # Always use Codex + gpt-5.4
ai --aws --opus --set-default     # Always use Claude Code + AWS + Opus
ai --clear-default                # Remove saved default

# Smart auto permissions (AI classifier for Claude Code, sandbox for Codex)
ai --auto task.md

# Enable agent teams (Claude Code, experimental, interactive only)
ai --team                         # Auto display mode
ai --aws --opus --team            # Teams with AWS Bedrock + Opus

Features

Executable Markdown

Create markdown files with prompts that run directly via shebang:

#!/usr/bin/env ai
Summarize the architecture of this codebase.

#!/usr/bin/env -S ai --aws
Use AWS Bedrock to analyze this code.

#!/usr/bin/env -S ai --codex --high
Use Codex CLI with the flagship model to review this code.

#!/usr/bin/env -S ai --opus --live
Review this PR for security issues. Stream output in real-time.

Scripts that write files or run commands need a permission mode:

#!/usr/bin/env -S ai --skip
Run ./test/automation/run_tests.sh and report results.

(--skip is a shortcut for --dangerously-skip-permissions. See also --bypass for --permission-mode bypassPermissions.)

#!/usr/bin/env -S ai --auto
Run tests and fix any issues found.

(--auto uses an AI classifier (Claude Code) or sandbox (Codex) to auto-approve safe actions.)

#!/usr/bin/env -S ai --allowedTools 'Bash(npm test)' 'Read'
Run the test suite and report results. Do not modify any files.

(--allowedTools is a Claude Code flag, passed through by AI Runner.)

Usage:

chmod +x task.md
./task.md                          # Execute directly (uses shebang flags)
ai --vercel task.md                # Override: use Vercel instead
ai --opus task.md                  # Override: use Opus instead

Tip: Use #!/usr/bin/env -S (with -S) to pass flags in the shebang line. Standard env only accepts one argument, so #!/usr/bin/env ai --aws won't work — you need -S to split the string.

Flag precedence: CLI flags > shebang flags > saved defaults. Running ai --vercel task.md overrides the script's shebang provider. Shebang flags override --set-default preferences.

Passthrough flags: AI Runner handles its own flags (provider, model, --live, --quiet, --skip, --bypass, --auto, --team, etc.) and forwards any unrecognized flags (e.g. --chrome, --allowedTools, --output-format, --verbose) to the underlying Claude Code process unchanged.

Portability: Scripts are portable across runtimes. If a script includes interpreter-specific flags (e.g., --chrome for Claude Code), running it on another runtime produces a warning but continues execution.

Warning: --skip, --bypass, and --permission-mode bypassPermissions give the AI full system access. Only run trusted scripts in trusted directories. Use --allowedTools for granular control. See docs/SCRIPTING.md for details.

See examples/ for ready-to-run scripts and docs/SCRIPTING.md for the full scripting & automation guide.

Script Variables

Declare variables with defaults in YAML front-matter. Users override them from the CLI without editing the script:

#!/usr/bin/env -S ai --haiku
---
vars:
  topic: "machine learning"
  style: casual
  length: short
---
Write a {{length}} summary of {{topic}} in a {{style}} tone.

./summarize-topic.md                          # uses defaults
./summarize-topic.md --topic "AI safety"      # overrides one
./summarize-topic.md --topic "robotics" --style formal  # overrides two

Boolean flags — --varname without a value sets the variable to "true":

# Given a script with vars: verbose: false
./script.md --verbose                         # sets verbose to "true"
./script.md --verbose --topic "AI safety"     # verbose="true", topic overridden

Variable overrides mix freely with AI Runner flags like --live and provider overrides:

./summarize-topic.md --live --length "100 words" --topic "the fall of rome" --style "peter griffin"
ai --aws --opus summarize-topic.md --topic "quantum computing"

Override flags matching declared var names are consumed — --live, --aws, and other unrecognized flags still pass through. Hyphens normalize to underscores (--brief-only matches brief_only). Only activates when front-matter contains vars: — no behavior change for existing scripts.

Unix Pipe Support

Executable markdown scripts have proper Unix semantics for automation:

Clean piped output - when you redirect to a file, you get only the AI's response
Stdin support - pipe data directly into scripts
Chainable - connect scripts together in pipelines
Standard streams - stdout is data, stderr is diagnostics

# Clean output to file
./analyze.md > results.txt

# Pipe data into scripts
cat data.json | ./process.md
git log --oneline -20 | ./summarize-changes.md

# Chain scripts together
./generate-report.md | ./format-output.md > final.txt

# Control stdin position (default: prepend)
cat data.txt | ./analyze.md --stdin-position append

Use in shell scripts:

#!/bin/bash
for f in logs/*.txt; do
    cat "$f" | ./analyze.md >> summary.txt
done

Composable scripts: AIRun clears inherited environment variables between nested calls, so chained scripts each start fresh. See docs/SCRIPTING.md for composable patterns, the dispatcher pattern (--cc --skip), and long-running script tips.

Piped Script Execution

Run AI scripts directly from the web:

# Run a script from the web
curl -fsSL https://andisearch.github.io/ai-scripts/analyze.md | ai

# Simple prompt via pipe
echo "Explain what a Dockerfile does" | ai

# Override provider from shebang
curl -fsSL https://example.com/script.md | ai --aws

Agent Teams (Experimental)

Enable Claude Code's agent teams — multiple Claude instances collaborating on shared tasks with one session as lead coordinating teammates.

ai --team                        # Enable agent teams
ai --aws --opus --team           # Combine with any provider
ai --team --teammate-mode tmux   # Split panes via tmux

Flag	Purpose
`--team`	AI Runner flag — enables agent teams by setting `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`
`--teammate-mode <mode>`	Claude Code native flag — controls display: `in-process`, `tmux`, or `auto` (default)

Interactive mode only (not supported in shebang/piped script modes)
Works with all providers — coordination is through Claude Code's internal task list, not provider-specific
Token usage scales with team size (5 teammates ≈ 5× tokens)

Runtimes and Providers

Runtimes

Flag	Runtime	Default Model	Install
`--cc`	Claude Code	claude-opus-4-7	`curl -fsSL https://claude.ai/install.sh \| bash`
`--codex`	Codex CLI	gpt-5.4	`npm install -g @openai/codex`

Claude Code is the default runtime when both are installed. If only Codex is installed, it becomes the default automatically.

Providers

Flag	Provider	Claude Code	Codex CLI	Type
`--ollama` / `--ol`	Ollama	Yes	Yes	Local
`--lmstudio` / `--lm`	LM Studio	Yes	Yes	Local
`--aws`	AWS Bedrock	Yes	—	Cloud
`--vertex`	Google Vertex AI	Yes	—	Cloud
`--apikey`	Anthropic / OpenAI API	Yes	Yes	Cloud
`--azure`	Azure Foundry / Azure OpenAI	Yes	Yes	Cloud
`--vercel`	Vercel AI Gateway	Yes	—	Cloud
`--pro`	Claude Pro	Yes	—	Subscription
`--profile <name>`	Config profile	—	Yes	Any

Codex custom providers (OpenRouter, Mistral, DeepSeek, etc.) are configured in ~/.codex/config.toml and selected with --profile <name>. See the Codex CLI docs for config.toml setup.

Quick Start Examples

# Local providers (free, no API costs — work with both runtimes)
ai --ollama                    # Claude Code + Ollama
ai --codex --ollama            # Codex CLI + Ollama

# Claude Code cloud providers
ai --aws --opus task.md        # AWS Bedrock + Opus 4.7
ai --vertex task.md            # Google Vertex AI

# Codex CLI cloud providers
ai --codex task.md             # OpenAI API + gpt-5.4
ai --codex --azure task.md     # Azure OpenAI (config.toml)

Provider Setup

Local Providers (Free, No API Keys)

Hardware note: Coding models need 24GB+ VRAM (or unified memory on Apple Silicon). Ollama's cloud models work on any hardware.

Ollama — runs models locally or on Ollama's cloud:

# Install Ollama
brew install ollama                   # macOS
curl -fsSL https://ollama.com/install.sh | sh  # Linux / WSL

# Quick setup (Ollama 0.15+)
ollama launch claude                  # Auto-configure and launch Claude Code

# Or manual setup
ollama pull qwen3-coder               # Pull a model (needs 24GB+ VRAM)
ai --ollama                           # Run with Ollama

# Cloud models — no GPU required, runs on Ollama's servers
ollama pull minimax-m2.5:cloud        # Best coding (80% SWE-bench, MIT)
ollama pull glm-5:cloud               # Best reasoning (78% SWE-bench, MIT)
ai --ollama --model minimax-m2.5:cloud

LM Studio — local models with MLX support (fast on latest Apple Silicon):

# 1. Download from lmstudio.ai and load a model
# 2. Start the server: lms server start --port 1234
ai --lm                               # Run with LM Studio

See docs/PROVIDERS.md for model recommendations, configuration, and auto-download features.

Cloud Providers

Add your credentials to ~/.ai-runner/secrets.sh (created by ./setup.sh). Andi AIRun loads this file automatically, so you don't need to set environment variables in your shell profile.

nano ~/.ai-runner/secrets.sh

Uncomment and fill in what you have:

# Anthropic API
export ANTHROPIC_API_KEY="sk-ant-..."

# AWS Bedrock
export AWS_PROFILE="your-profile-name"
export AWS_REGION="us-west-2"

# Google Vertex AI
export ANTHROPIC_VERTEX_PROJECT_ID="your-gcp-project-id"
export CLOUD_ML_REGION="global"

# Vercel AI Gateway
export VERCEL_AI_GATEWAY_TOKEN="vck_..."

# Microsoft Azure
export ANTHROPIC_FOUNDRY_API_KEY="your-azure-api-key"
export ANTHROPIC_FOUNDRY_RESOURCE="your-resource-name"

You only need to configure the providers you want to use. See docs/PROVIDERS.md for all authentication options and detailed setup instructions.

Switching Providers to Avoid Rate Limits

Claude Pro has rate limits. When you hit a limit mid-task, switch to your API keys and keep working.

# Working with Claude Pro, hit rate limit
claude
# "Rate limit exceeded. Try again in 4 hours 23 minutes."

# Immediately continue with AWS (keeps conversation context)
ai --aws --resume

# Or switch to Haiku for speed/cost, Opus for complex reasoning
ai --aws --haiku --resume
ai --aws --opus --resume

# Or use local Ollama (free!)
ai --ollama --resume

The --resume flag lets you pick up a previous conversation exactly where you left off.

Installation

Setup

git clone https://github.com/andisearch/airun.git
cd airun
./setup.sh

The setup script installs commands to /usr/local/bin, creates ~/.ai-runner/ for configuration, and migrates any existing ~/.claude-switcher/ configuration.

Note: Setup does NOT modify your Claude configuration. All scripts are session-scoped and automatically restore your original configuration on exit.

Updating

ai update

Or manually: cd airun && git pull && ./setup.sh

AI Runner checks for updates once every 24 hours (non-blocking, cache-only) and shows a notice in interactive mode and ai-status when a new version is available. Disable with export AI_NO_UPDATE_CHECK=1.

Your API keys in ~/.ai-runner/secrets.sh are preserved.

Updating from claude-switcher

If you have the original claude-switcher installed, just pull and re-run setup:

cd claude-switcher && git pull && ./setup.sh

GitHub's redirect ensures git operations continue working with the old remote URL.

What happens automatically:

Your ~/.claude-switcher/secrets.sh is migrated to ~/.ai-runner/secrets.sh
All legacy claude-* commands continue to work (see Backward Compatibility)
Existing #!/usr/bin/env claude-run shebangs still work

Optional cleanup:

# Rename local directory
cd .. && mv claude-switcher airun && cd airun

# Update remote to canonical URL
git remote set-url origin https://github.com/andisearch/airun.git

New commands: ai / airun replace claude-run as the primary entry point.

Uninstallation

./uninstall.sh

Backward Compatibility

All legacy claude-* commands continue to work unchanged:

Legacy Command	Equivalent
`claude-run`	`ai`
`claude-aws`	`ai --aws`
`claude-vertex`	`ai --vertex`
`claude-apikey`	`ai --apikey`
`claude-azure`	`ai --azure`
`claude-vercel`	`ai --vercel`
`claude-pro`	`ai --pro`
`claude-status`	`ai-status`
`claude-sessions`	`ai-sessions`

Existing shebang scripts with #!/usr/bin/env claude-run still work.

Configuration in ~/.claude-switcher/ is automatically migrated to ~/.ai-runner/.

Configuration

Models

Default model IDs are defined in config/models.sh. Override them in ~/.ai-runner/secrets.sh:

# Override Claude Code AWS model
export CLAUDE_MODEL_SONNET_AWS="global.anthropic.claude-sonnet-4-6"

# Override Codex model tiers
export CODEX_MODEL_HIGH="gpt-5.4"
export CODEX_MODEL_MID="gpt-5.3-codex"
export CODEX_MODEL_LOW="gpt-5.4-mini"

# Save preferred runtime + provider + model as default
ai --codex --high --set-default
ai --aws --opus --set-default
ai --clear-default              # Remove saved default

Dual Model Configuration

Claude Code uses two models:

ANTHROPIC_MODEL - Main model for interactive work
ANTHROPIC_SMALL_FAST_MODEL - Background operations (defaults to Haiku)

Troubleshooting

Verify Configuration

ai-status                              # Shows authentication and configuration

Common Issues

Still getting rate limits after switching to API?

Verify API key: grep ANTHROPIC_API_KEY ~/.ai-runner/secrets.sh
Confirm you're using ai (not plain claude)
Run ai-status during the session
In Claude, run /status to see authentication method

Switching back to Pro not working?

Use ai --pro or plain claude
Run /status in Claude to verify authentication

Want to pin to a specific Opus version (e.g. 4.6)?

Whether you prefer an older release for personal-preference reasons, hit a transient provider bug with the latest one, or want to avoid a known regression in your workload, you can pin Opus across all providers in ~/.ai-runner/secrets.sh:

export CLAUDE_MODEL_OPUS_AWS="global.anthropic.claude-opus-4-6-v1"
export CLAUDE_MODEL_OPUS_VERTEX="claude-opus-4-6"
export CLAUDE_MODEL_OPUS_ANTHROPIC="claude-opus-4-6"
export CLAUDE_MODEL_OPUS_AZURE="claude-opus-4-6"
export CLAUDE_MODEL_OPUS_VERCEL="anthropic/claude-opus-4.6"

# Also pin the in-session /model picker's "Default" alias.
export ANTHROPIC_DEFAULT_OPUS_MODEL="claude-opus-4-6"

See Pinning Opus to a specific version for the full explanation.

Session-Scoped Behavior

ai with no flags matches your claude defaults — subscription if logged in, API key if configured. Provider flags (--aws, --ollama, etc.) only affect the current session:

On exit, your original Claude settings are automatically restored
Plain claude in another terminal is completely unaffected
No global configuration is changed
