* fix(anthropic): strip LiteLLM-injected total_tokens from /v1/messages response The non-streaming /v1/messages response carries a LiteLLM-injected usage.total_tokens = input_tokens + output_tokens that is not part of the Anthropic API spec. This caused three problems: 1. Shape divergence with streaming on the same endpoint. message_delta.usage in the SSE path never carries total_tokens. Clients parsing both paths get two different schemas from one endpoint. 2. Shape divergence with upstream. Direct calls to https://api.anthropic.com/v1/messages return no total_tokens field, so clients using the official Anthropic SDK couldn't rely on it, and clients that did rely on the LiteLLM-injected one broke when bypassing the proxy. 3. Numerical misuse. total = input + output undercounts when cache_read_input_tokens and cache_creation_input_tokens are non-zero, because cache tokens are reported in their own fields. A 100k-token cached prompt with 1 non-cache input token + 200 output tokens reports total_tokens = 201, off by ~99.8% from any reasonable definition of "total." Fix: add _strip_total_tokens_from_anthropic_response in litellm/proxy/anthropic_endpoints/endpoints.py and invoke it in the success path of anthropic_response right before returning. Only mutates dict-shaped responses; streaming (which already lacks the field) is left untouched. spend_logs / Prometheus continue to compute total_tokens internally for billing — this fix only strips the field from the wire response. Scope: only the Anthropic passthrough endpoint /v1/messages. The OpenAI-shape /v1/chat/completions is unaffected. * fix(anthropic): gate total_tokens strip behind flag + handle Pydantic .usage Two P1 greptile threads on #30382: P1 — **Backwards-incompatible removal without a feature flag** Stripping `usage.total_tokens` unconditionally breaks any client currently reading the LiteLLM-shaped non-streaming /v1/messages response. Per the codebase's policy (mirrors #30418), gate behind a new flag. - `litellm.strip_anthropic_total_tokens: bool = False` (default — backward-compat: clients keep seeing total_tokens). - Env override: `LITELLM_STRIP_ANTHROPIC_TOTAL_TOKENS=true`. - Docstring: planned to flip to True in a future major release; opt in early. P1 — **Silent no-op if `result` is a Pydantic model** `base_process_llm_request` may return a Pydantic-style object whose `.usage` is a plain dict (the most common shape — e.g. objects wrapping raw upstream JSON). The original `isinstance(response, dict)` guard skipped strip on those, so `total_tokens` would still hit the wire. Helper now also reads `getattr(response, "usage", None)` and strips when that's a dict. Strongly-typed Pydantic `Usage` sub-models with required `total_tokens` fields are still skipped — those impose type constraints the helper doesn't try to subvert. Tests: - `test_strips_total_tokens_on_pydantic_model_with_dict_usage` - `test_flag_defaults_off` 8/8 pass locally. * fix(anthropic): drop env var for strip flag (docs CI) Mirrors #30418's pattern (`expose_router_debug_in_errors: bool = True`, no `os.getenv`). The `LITELLM_STRIP_ANTHROPIC_TOTAL_TOKENS` env var introduced in the prior commit was flagged by `tests/documentation_tests/test_env_keys.py` because the documentation file `docs/my-website/docs/proxy/config_settings.md` lives in `BerriAI/litellm-docs` (separate repo) and registering a new env key requires a parallel docs PR — a friction we avoid here by exposing the flag only as a Python attribute + `litellm_settings` config key, both of which load through the existing proxy config plumbing without needing the env-var registry to be updated. No semantic change: default still False, behavior identical when set via `litellm.strip_anthropic_total_tokens = True` or `litellm_settings.strip_anthropic_total_tokens: true` in config.yaml. Verified locally: env scan no longer surfaces the key; 8/8 tests pass. * ci: retrigger workflows after base branch change to litellm_internal_staging |
