Both are valid Azure OpenAI surfaces in production today. The OpenAI pass-through cost-tracking handler hard-codes only the older hostname in five places (four `is_openai_*_route` methods on OpenAIPassthroughLoggingHandler, plus is_openai_route on PassThroughEndpointLogging). As a result, calls from newer Azure deployments are silently classified as "not an OpenAI route", the dispatch into the cost-tracking handler is skipped, and tokens/cost never get extracted into LiteLLM_SpendLogs — the row gets written with prompt_tokens=0, completion_tokens=0, spend=0, model='unknown'. Reproduced 2026-06-04 against a real Azure OpenAI deployment on `*.cognitiveservices.azure.com` proxied through LiteLLM v1.88.0. Fix: factor the hostname check into a single helper `_is_openai_compatible_host` listing all three recognized surfaces (api.openai.com, openai.azure.com, cognitiveservices.azure.com), and have all five call sites delegate to it. Purely additive — never weakens recognition for the originally-supported hostnames. Adds a test `test_is_openai_route_recognizes_cognitiveservices_azure_com` that exercises all four `is_openai_*_route` static methods against `*.cognitiveservices.azure.com` URLs (positive cases per route + a small cross-route negative to confirm route-specific path matching still works on the new hostname). Out of scope for this PR (separate followup): - `openai_passthrough_handler` calls chat/completions `transform_response` on Responses API payloads (`output:` not `choices:`), which throws inside the dispatch and drops the SpendLogs row entirely. Recognized + tracked separately. * ci: trigger fresh run Empty commit to re-run checks. The previous auth-and-jwt failure was a transient HuggingFace Hub 429 rate-limit hitting tokenizer downloads in tests/proxy_unit_tests/test_custom_tokenizer_bug.py — unrelated to this PR's scope (hostname recognition in pass-through cost tracking). No code change. --------- Co-authored-by: shin-berri <shin-laptop@berri.ai> Co-authored-by: yuneng-jiang <yuneng@berri.ai> * fix(responses): preserve forced-function tool_choice name in Responses to Chat transform (#29812) The Responses API forces a specific function with a top-level name ({"type": "function", "name": "X"}), but _transform_tool_choice only handled the nested Chat Completions shape and fell through to returning "required" for the flat form, silently dropping the function name and degrading a forced function call to force-any-tool. Map the flat Responses shape to the nested Chat shape, keeping the "required" fallback when no name is present. * Preserve x-anthropic-billing-header system blocks for first-party Anthropic (#29584) * Preserve x-anthropic-billing-header system blocks for first-party Anthropic PR #20951 strips system blocks beginning with "x-anthropic-billing-header:" for every Anthropic target. That block is how the first-party Anthropic API recognizes Claude Code subscription (OAuth) traffic, so dropping it makes requests that carry only that block, such as the auto-mode tool-safety classifier, fail with a misleading 429 rate_limit_error; normal turns still work because they also carry the "You are Claude Code" identity block. Gate the strip behind should_strip_billing_metadata(), defaulting to False on the first-party AnthropicConfig and AnthropicMessagesConfig so the block is kept, and overridden to True on the providers that reach these transforms and reject the block (Bedrock platform, Vertex, Azure for the chat path; Minimax, Azure, DeepSeek for the messages path). Behavior for those providers is unchanged. * Strip billing header on Bedrock invoke and Vertex messages pass-through Two more subclasses reach the gated strip but inherited keep-by-default. AmazonAnthropicClaudeConfig (Bedrock invoke) calls AnthropicConfig.transform_request, which calls translate_system_message, and VertexAIPartnerModelsAnthropicMessagesConfig (Vertex messages pass-through) calls super().transform_anthropic_messages_request. Override should_strip_billing_metadata() to True on both. Add a parametrized test asserting the flag for every first-party base (False) and provider subclass (True), covering all overrides, plus a translate_system_message regression test for the Bedrock invoke path. * fix(cache): log hashed cache keys (#29890) * fix(ui): save routing groups as list (#29889) * Revert "fix(ui): save routing groups as list (#29889)" (#29928) This reverts commit 9b1f78ffa7a309cabe5e9a7ab5f94d1224d192c9. * feat(parasail): add Parasail as a JSON-configured OpenAI-compatible provider (#29842) * feat(parasail): add Parasail as a JSON-configured OpenAI-compatible provider Registers parasail in the openai_like JSON provider loader with both /v1/chat/completions and /v1/responses support. Parasail's Responses API rejects store:true and any request that omits store, so the loader gains a force_store_false special_handling flag; the parasail entry sets it and the generated Responses config overrides store=false on every call. This keeps callers from hitting "State storage not supported" and matches what Parasail's docs require. Adds the PARASAIL enum value, listing under openai_compatible_providers, provider documentation at docs/my-website/docs/providers/parasail.md, and a focused unit test file under tests/test_litellm/llms/parasail/ that covers JSON registration, chat URL construction, Responses URL construction with PARASAIL_API_BASE override, and the force_store_false regression in both the caller-sent-store=true and caller-omitted cases. * fix(parasail): register in provider_endpoints_support, drop in-repo docs Greptile review feedback. The provider doc belongs in the litellm-docs repo, not this one's docs/my-website tree; removing it here. Adds the parasail entry to provider_endpoints_support.json so the check_provider_folders_documented.py CI check passes (chat_completions and responses true; others false). * fix: normalize Anthropic passthrough server tool usage (#29827) * test(anthropic): cover server_tool_use dict cost tracking * fix: normalize Anthropic server tool usage (cherry picked from commit 982f726bed7d3ec05e463c5dd3d090bebae91d19) * fix: keep server tool usage subscriptable (cherry picked from commit 70280b9b272455b2f974d08bc697f67f929755bf) --------- Co-authored-by: Genmin <joey@joeyroth.com> * fix(proxy): fix typo generic_role_mappoings -> generic_role_mappings in ui_sso.py (#29753) Co-authored-by: shin-berri <shin-laptop@berri.ai> Co-authored-by: yuneng-jiang <yuneng@berri.ai> * feat(proxy): add disable_budget_reservation general setting (#27639) (#29493) * feat(proxy): add disable_budget_reservation general setting (#27639) * feat(proxy): register disable_budget_reservation in ConfigGeneralSettings (#27639) * docs(proxy): document disable_budget_reservation concurrency tradeoff (#27639) * ci: re-trigger flaky docker build (prisma generate ECONNRESET) * fix(proxy): warn and document budget enforcement tradeoff when disable_budget_reservation is set (#27639) * feat(gemini_tts): adding support to Gemini TTS languageCode parameters (#29623) * Adding support to Gemini TTS Language Code parameters * Mapping Gemini TTS languageCode param in Docstring * Use snake_case for language_code input keyMapping Gemini TTS languageCode param in Docstring * Restoring files modified under enterprise/litellm_enterprise due to lint/formatting checks --------- Co-authored-by: João Garrido <joaogarrido@google.com> * feat(guardrails): capture user and model metadata in CrowdStrike AIDR (#29517) * fix(proxy): require OpenAI path segment for shared Azure Cognitive Services domains Address Greptile review: the `*.cognitiveservices.azure.com` / `*.openai.azure.com` domains are shared by every Azure Cognitive Service (Speech, Vision, Language, ...), so a hostname-only substring match misclassified non-OpenAI Azure traffic as OpenAI routes. - Replace the substring host test with suffix matching (rejects look-alike domains like cognitiveservices.azure.com.attacker.example). - Add `_is_openai_compatible_url` that requires an OpenAI-style path marker (`/openai/` or `/v1/`) on the shared Azure domains, and use it in PassThroughEndpointLogging.is_openai_route (previously hostname-only). - Add negative tests for Azure Speech/Vision paths and look-alike domains.

Unit tests for individual LLM providers.
Name of the test file is the name of the LLM provider - e.g. test_openai.py is for OpenAI.
Redis-backed VCR cache
Every test in this directory is auto-decorated with @pytest.mark.vcr (via
conftest.py). The first time a test runs we hit the live provider and
record the HTTP exchange into Redis under
litellm:vcr:cassette:<test_id>. Every subsequent run within 24h replays
from Redis without touching the network. The 24h TTL means each new day's
first run records again, so upstream API drift surfaces within a day.
The persister, header scrubbing, and 2xx-only filtering are defined in
tests/_vcr_redis_persister.py. Files that already use respx (which
patches the same httpx transport vcrpy does) are excluded from the
auto-marker — see _RESPX_CONFLICTING_FILES in conftest.py.
The same VCR cache is used by other test directories that exercise live
provider APIs. The reusable conftest plumbing lives in
tests/_vcr_conftest_common.py and is wired into:
tests/llm_translation/tests/llm_responses_api_testing/tests/audio_tests/tests/batches_tests/tests/guardrails_tests/tests/image_gen_tests/tests/litellm_utils_tests/tests/local_testing/(coverslocal_testing_part1,local_testing_part2,litellm_router_testing,litellm_assistants_api_testing,langfuse_logging_unit_tests)tests/logging_callback_tests/tests/pass_through_unit_tests/tests/router_unit_tests/tests/unified_google_tests/
Test directories that run LiteLLM proxy in Docker (e.g. build_and_test,
proxy_logging_guardrails_model_info_tests, proxy_store_model_in_db_tests)
are intentionally not included: VCR.py patches the in-process httpx
transport, so it cannot intercept the LLM calls that originate inside the
Docker container.
Required environment
CASSETTE_REDIS_URL — separate Redis instance from the application
Redis (REDIS_URL/REDIS_HOST) so test cassettes are not flushed by
proxy tests. Provider credentials (ANTHROPIC_API_KEY, OPENAI_API_KEY,
AWS_*, etc.) are needed only on cache-miss (the daily re-record), not
on replay.
Flushing the cache
When you want the next run to re-record immediately instead of waiting for the 24h TTL:
make test-llm-translation-flush-vcr-cache
Disabling VCR
Skip the cache entirely (every call goes live, no recording):
LITELLM_VCR_DISABLE=1 uv run pytest tests/llm_translation/test_<file>.py
