Mateo Wang ef1d3959a0 fix(count_tokens)!: answer 400 for Vertex partner models without a count API and OpenAI-shaped provider errors on /v1/responses/input_tokens (#47163) ... * fix(count_tokens): answer 400 for Vertex partner models without a count API and OpenAI-shaped provider errors on /v1/responses/input_tokens * fix(count_tokens): answer 400 for Vertex Mistral counts and type the input_tokens error tests Vertex has no count-tokens route for Mistral or codestral models, so they now get the same 400 as other partner models without a count API instead of a 404 that points operators at IAM. * fix(count_tokens): unwrap prefixed provider errors on /v1/responses/input_tokens * fix(count_tokens): say LiteLLM, not Vertex, cannot count a Vertex partner model * fix(count_tokens): count a Vertex partner model with its configured custom_tokenizer and unwrap prefixed flat provider errors * fix(count_tokens): keep the 400 for contents-only Vertex partner counts with a custom_tokenizer * fix(count_tokens): pass through an OpenAI provider error that omits param or code * fix(count_tokens): keep the status-based type for Anthropic count errors on the Responses route * test(count_tokens): cover the Vertex partner count gate and Responses count error shapes on a real proxy * test(count_tokens): add regression tests for the Vertex partner count gate and Responses count error shapes		2026-10-17 21:15:38 +00:00
