 | LITELLM_OTEL_INTEGRATION_ENABLE_EVENTS | Optionally enable semantic logs (`gen_ai.content.prompt`/`gen_ai.content.completion`, or `gen_ai.client.inference.operation.details` in semconv mode) for OTEL. Default `false`. See [OpenTelemetry](/docs/observability/opentelemetry_integration#configuration-reference)
 | LITELLM_OTEL_INTEGRATION_ENABLE_METRICS | Optionally enable semantic metrics (TTFT, TPOT, response duration, cost, token usage) for OTEL. Default `false`. See [OpenTelemetry](/docs/observability/opentelemetry_integration#metrics-reference)
 | LITELLM_OTEL_BAGGAGE_TEAM_METADATA_KEYS | Comma-separated allowlist of team-metadata sub-keys promoted onto OTEL spans under `litellm.team.metadata`. Empty by default, so none of a team's free-form metadata is sent to your tracing backend until each sub-key is explicitly allowlisted. Also settable as `baggage_team_metadata_keys` under `callback_settings.otel` in config.yaml. See [OpenTelemetry](/docs/observability/opentelemetry_integration).
+| LITELLM_ENABLE_HTTP2 | If true, opts in to HTTP/2 for outbound LLM requests (equivalent to `litellm.enable_http2 = True`). Requires the `h2` package. Off by default; falls back to HTTP/1.1 over aiohttp when unset.
 | LITELLM_ENABLE_PYROSCOPE | If true, enables Pyroscope CPU profiling. Profiles are sent to PYROSCOPE_SERVER_ADDRESS. Off by default. See [Pyroscope profiling](/proxy/pyroscope_profiling).
 | LITELLM_ENABLE_TEAM_STALE_ALIAS_BYPASS | When `true`, if a team's legacy `model_aliases` entry maps a public model name to an internal `model_name_<team_id>_<uuid>` deployment, pre-call handling can skip that rewrite when team-scoped sibling deployments exist for the public name—so load balancing / `order` apply across siblings. Default is `false` for backwards compatibility. See [Team-scoped models and legacy aliases](./load_balancing#team-scoped-models-and-legacy-model_aliases). When stale aliases are detected and this flag is off, the proxy may log a one-time warning.
 | PYROSCOPE_APP_NAME | Application name reported to Pyroscope. Required when LITELLM_ENABLE_PYROSCOPE is true. No default.
