mask was missing from get_supported_openai_params, causing it to be
dropped before reaching transform_image_edit_request where it is
already handled correctly for flux-pro-1.0-fill inpainting.
- Propagate timeout to each polling GET request to prevent indefinite hangs
- Validate HTTP status code of initial POST before parsing JSON
- Fix inline import and add 60s timeout to image URL download in _read_image_bytes
- Fix F821: add BaseTokenCounter TYPE_CHECKING import in gpt_transformation.py
- Remove duplicate auth invocation in count_response_input_tokens endpoint
- Preserve `strict` field during chat→Responses API tool conversion
- Fix docs tools example to use chat completions format (not Responses API format)
- Return None early for system-only messages to avoid noisy error logs
Match the error handling pattern used in the Anthropic count_tokens
endpoint: catch ProxyException separately to surface its status code
and message, and include error details in the generic 500 fallback.
The user-specified async client was being overwritten by
`litellm.module_level_aclient` in `streaming_handler.py` when using
async+streaming with Gemini.
This fix adds a `gemini_client` parameter to `make_call()` (matching
the existing pattern in `make_sync_call()`) so the user's custom client
is preserved and not overwritten.
Fixes#17148
- Log provider token counting failures instead of silently swallowing
- Fall back to local tokenizer when provider returns error response
- Map assistant tool_calls to Responses API function_call items
- Concatenate multiple system messages instead of overwriting
- Hide internal error details from proxy API responses
- Narrow exception catch in handler to network/JSON errors only
- Update test to match new fallback behavior
- Add OpenAITokenCounter using POST /v1/responses/input_tokens endpoint
- Add litellm.acount_tokens() public async API that auto-routes to provider APIs
- Add proxy endpoint POST /v1/responses/input_tokens for OpenAI-compatible counting
- Transform chat tools format to Responses API format for correct token counting
- Fall back to local tiktoken when provider API unavailable
Fixes#22302
Kontext models (flux-kontext-pro, flux-kontext-max) support both
text-to-image and image editing. Add them to IMAGE_GENERATION_MODELS
and update supported_endpoints in model prices JSON.
- Change mode from "image_generation" to "image_edit" for all 4 BFL
image edit models (flux-kontext-pro, flux-kontext-max, flux-pro-1.0-fill,
flux-pro-1.0-expand)
- Rename shadowed api_base variable to complete_url in async handler
for consistency with sync path
- Remove response_format from supported params (BFL always returns URLs)
- Remove n and size from image edit supported params (not mapped)
- Raise ValueError on unknown model names instead of silently defaulting
- Create handler.py for image generation and image edit
- Move polling logic from transformation to handlers
- Handlers use _get_httpx_client() / get_async_httpx_client()
- Transformation files now only transform request/response data
- Follows Bedrock pattern for provider-specific handlers
Addresses feedback: transformation files should not make HTTP requests
Add native text-to-image generation for Black Forest Labs Flux models
(flux-pro-1.1, flux-pro-1.1-ultra, flux-dev, flux-pro).
- Polling-based async API with sync and async support
- OpenAI-compatible parameter mapping (size, n, quality)
- Reuses shared HTTP clients via _get_httpx_client()
- 39 unit tests added
Replace direct httpx.get() calls with _get_httpx_client() to reuse
cached HTTP client, following the pattern used by other providers
(RunwayML, Azure AI OCR, Sagemaker, etc.).
Add BFL models to model_prices_and_context_window.json with pricing:
- flux-kontext-pro: $0.04/image
- flux-kontext-max: $0.08/image
- flux-pro-1.0-fill: $0.05/image
- flux-pro-1.0-expand: $0.05/image
Add black_forest_labs_models set to __init__.py for model discovery.
Add native integration for Black Forest Labs image editing models
(flux-kontext-pro, flux-kontext-max, flux-pro-1.0-fill, flux-pro-1.0-expand).
Changes:
- Add BlackForestLabsImageEditConfig for BFL API transformation
- Add BLACK_FOREST_LABS to LlmProviders enum
- Add use_multipart_form_data() to BaseImageEditConfig for JSON vs form-data
- Modify image_edit_handler to support JSON request bodies
- Add comprehensive unit tests
Closes#11401
