Set cached tokenizer config directly and mock both sync and async
tokenizer functions to avoid race conditions when running with
parallel test execution (-n 16).
The issue was that parallel tests could populate the
litellm.known_tokenizer_config cache between clearing it and
when the code checked it. This caused the sync code path to be
used instead of the async path, bypassing the mocked async functions.
Fix:
1. Set cache directly instead of clearing it
2. Also mock sync versions _get_tokenizer_config and _get_chat_template_file
This ensures the test is deterministic regardless of test execution order.

* fix: use dict access for anthropic content blocks in tests (#20447)
The translate_openai_response_to_anthropic method returns dicts, not objects.
Changed .type/.text/.thinking attribute access to dict ['key'] access.

AsyncHTTPHandler.__del__ was closing httpx clients still in use by
AsyncOpenAI/AsyncAzureOpenAI due to independent cache lifecycles.
Restores standalone httpx client creation for OpenAI/Azure providers.

* fix: resolve mypy union-attr errors in anthropic guardrail handler
Cast choices[0] to Choices type before accessing .message attribute
to satisfy mypy's union type checking for Choices | StreamingChoices.

Add x-api-key header to CountTokens handler to match chat completion
authentication. Azure AI Anthropic requires this header per Microsoft's
native API format.
When using LiteLLM's Anthropic /v1/messages endpoint to route requests to
OpenAI models, requests fail if any tool name exceeds OpenAI's 64-character
limit. Anthropic API has no such limit, causing compatibility issues.
Changes:
- Add truncate_tool_name() function using {55-char-prefix}_{8-char-hash} format
- Modify translate_anthropic_tools_to_openai() to truncate and return mapping
- Modify translate_anthropic_tool_choice_to_openai() to truncate tool name
- Restore original tool names in responses using the mapping
- Support tool name restoration in streaming responses
- Add backwards-compatible API (existing methods still work)
The fix only applies when routing Anthropic requests to OpenAI models.
Native Anthropic/Claude requests pass through unchanged.
Fixes#19788
- Add `supported_regions: ["global"]` to Qwen MaaS models in model_prices_and_context_window.json
- Update `get_supported_regions()` to read directly from `model_cost` dict
- Update `get_complete_vertex_url()` to use `get_vertex_region()` for global-only models
- Update `create_vertex_url()` to generate correct URL for global location (without region prefix)
- Add tests for Qwen global endpoint support
Per review feedback, thought_signature should not be a root-level
param on ImageObject as it's not OpenAI compatible. Moved to
provider_specific_fields dict to match the pattern used in chat
completions (Message, Delta, Choices, etc).
Fixes#17184 - Gemini 3 Pro image preview model returns a thoughtSignature
field required for interactive image editing. This change:
- Adds thought_signature field to ImageObject class
- Updates Gemini and Vertex AI transformations to extract thoughtSignature
- Adds test for thought_signature in response transformation
