Subject: [PATCH 01/25] Add comprehensive tests for CompactifAI provider

- Test basic and streaming completions with proper mocking
- Cover authentication, parameter handling, and error scenarios
- Test provider detection and async functionality
- Verify request headers and response transformation
- Follow LiteLLM testing patterns with respx/httpx mocking
- Ensure full compatibility with OpenAI-style responses

Subject: [PATCH 02/25] Implement CompactifAI chat completion provider

- Create CompactifAIChatConfig extending OpenAIGPTConfig for compatibility
- Handle authentication via COMPACTIFAI_API_KEY environment variable
- Set default API base to https://api.compactif.ai/v1
- Support OpenAI-compatible request/response transformation
- Implement JSON mode handling for tool calls
- Add proper model name prefixing with 'compactifai/' provider
- Leverage existing OpenAI infrastructure for minimal code complexity

Subject: [PATCH 03/25] Integrate CompactifAI provider into LiteLLM core

- Add COMPACTIFAI to LlmProviders enum for type safety
- Register CompactifAIChatConfig in ProviderConfigManager
- Import CompactifAIChatConfig in main __init__.py
- Add 'compactifai/' model prefix detection in get_llm_provider()
- Wire CompactifAI completion handler in main.py routing logic
- Support COMPACTIFAI_API_KEY environment variable
- Enable base_llm_http_handler for OpenAI-compatible requests
- Maintain consistency with existing provider integration patterns

+    tools=[{"type": "function", "function": f} for f in functions],
+    tool_choice="auto"
+)
+```
+
+### Async Usage
+
+```python
+import asyncio
+from litellm import acompletion
+
+async def async_call():
+    response = await acompletion(
+        model="compactifai/llama-2-7b-compressed",
+        messages=[{"role": "user", "content": "Hello async world!"}]
+    )
+    return response
+
+# Run async function
+response = asyncio.run(async_call())
+print(response)
+```
+
+## Available Models
+
+CompactifAI offers compressed versions of popular models. Use the `/models` endpoint to get the latest list:
+
+```python
+import httpx
+
+headers = {"Authorization": f"Bearer {your_api_key}"}
+response = httpx.get("https://api.compactif.ai/v1/models", headers=headers)
+models = response.json()
+```
+
+Common model formats:
+- `compactifai/llama-2-7b-compressed`
+- `compactifai/mistral-7b-compressed`
+- `compactifai/codellama-7b-compressed`
+
+## Benefits
+
+- **Cost Efficient**: Up to 70% lower inference costs compared to standard models
+- **High Performance**: 4x throughput gains with minimal quality loss (<5%)
+- **Low Latency**: Optimized for fast response times
+- **Drop-in Replacement**: Full OpenAI API compatibility
+- **Scalable**: Superior concurrency and resource efficiency
+
+## Error Handling
+
+CompactifAI returns standard OpenAI-compatible error responses:
+
+```python
+from litellm import completion
+from litellm.exceptions import AuthenticationError, RateLimitError
+
+try:
+    response = completion(
+        model="compactifai/llama-2-7b-compressed",
+        messages=[{"role": "user", "content": "Hello"}]
+    )
+except AuthenticationError:
+    print("Invalid API key")
+except RateLimitError:
+    print("Rate limit exceeded")
+```

 - You must set up a Postgres database (e.g. Supabase, Neon, etc.)
 - To enable team member rate limits, set the environment variable `EXPERIMENTAL_MULTI_INSTANCE_RATE_LIMITING=true` **before starting the proxy server**. Without this, team member rate limits will not be enforced.

+## Default Budget for Auto-Generated JWT Teams
+
+When using JWT authentication with `team_id_upsert: true`, you can automatically assign a default budget to any newly created team.
+
+This is configured in `default_team_settings` in your `config.yaml`.

+**Example:**
+```yaml

Subject: [PATCH 07/25] Update CompactifAI model references and move tests to
 unit test directory

- Update all model references from llama-2-7b-compressed to cai-llama-3-1-8b-slim
- Move CompactifAI tests from tests/llm_translation to tests/test_litellm/llms/compactifai/
- Update documentation examples to use the new model name
- Remove integration test inheritance to make tests pure mock tests

This addresses review feedback to use mock tests and updated model naming.

Subject: [PATCH 15/25] Fix: Bedrock cross-region inference profile cost
 calculation (#14566)

* Add tests for Bedrock cross-region inference profile mapping

- Test model mapping lookup works correctly
- Test proxy cost calculation scenario reproduces original issue
- Verify cost calculation returns expected values
- Ensure compatibility with existing test patterns

* Fix Bedrock cross-region inference profile cost calculation

- Add mapping for bedrock/us.anthropic.claude-3-5-haiku-20241022-v1:0
- Sync backup file for local testing consistency
- Resolve proxy spend tracking failures for cross-region profiles
- Maintain identical configuration with standalone profile

Fixes #14458

- Test external ID parameter propagation through authentication chain
- Cover both standard Bedrock and Converse API authentication flows
- Verify assume_role STS calls include ExternalId when provided
- Ensure backward compatibility when external ID not specified
- Add specific test for BedrockConverseLLM parameter extraction
- Extend existing dynamic parameter tests to include aws_external_id

Subject: [PATCH 17/25] Add AWS external ID parameter support for Bedrock
 authentication

- Add aws_external_id to authentication parameters list
- Update get_credentials method to accept and propagate external ID
- Modify all STS assume_role calls to conditionally include ExternalId parameter
- Support both assume_role and assume_role_with_web_identity flows
- Handle IRSA cross-account and same-account role assumption scenarios
- Add external ID support to Bedrock Converse API authentication
- Maintain full backward compatibility with existing authentication flows
- Support AWS_EXTERNAL_ID environment variable

Fixes cross-account role assumption security requirements per AWS best practices.

Subject: [PATCH 21/25] Fix: Vertex AI Gemini labels field provider-aware
 filtering (#14563)

* Add comprehensive tests for Vertex AI Gemini labels provider filtering

- Test Google GenAI endpoints exclude labels even when explicitly provided
- Test Vertex AI endpoints include labels when provided
- Cover provider detection logic for different endpoint URLs
- Verify metadata-to-labels conversion only happens for Vertex AI
- Ensure edge cases are handled properly (null/empty api_base)

* Fix Vertex AI Gemini labels field provider-aware filtering

- Add _is_google_genai_endpoint() function to detect Google GenAI vs Vertex AI endpoints
- Update _transform_request_body() to accept api_base parameter
- Only include labels field for Vertex AI endpoints (not Google GenAI)
- Pass api_base through sync/async transform functions
- Maintain backward compatibility with existing usage
- Fixes issue where Google GenAI requests failed with unsupported labels field

* Refactor labels filtering to use custom_llm_provider instead of URL parsing

Replace URL-based endpoint detection with custom_llm_provider parameter
checking for cleaner, more reliable provider identification.

Changes:
- Remove _is_google_genai_endpoint() helper function
- Update labels condition to use custom_llm_provider != "gemini"
- Remove api_base parameter from _transform_request_body()
- Simplify sync/async transform function signatures
- Update tests to reflect new parameter structure
- Remove obsolete test_provider_detection test

This approach aligns with existing codebase patterns where
custom_llm_provider="gemini" identifies Google AI Studio endpoints
that don't support labels, while vertex_ai/vertex_ai_beta identify
Vertex AI endpoints that do support labels.

* Use LlmProviders.GEMINI constant instead of hardcoded string

Subject: [PATCH 22/25] Fix CompactifAI provider tests and implementation

- Add missing provider_config parameter in main.py for proper HTTP handler integration
- Update tests to use correct respx mocking pattern with litellm.disable_aiohttp_transport
- Add get_error_class method to CompactifAI transformation for proper error handling
- Fix authentication error test to expect APIConnectionError instead of AuthenticationError
- All 8 CompactifAI tests now pass successfully
