Add tracing for the Google GenAI generate_images API (both sync and async). This includes patchers, input/output serialization, metric extraction, and VCR-based tests with image payload sanitization to keep cassettes small.

Key changes:

  • ModelsGenerateImagesPatcher and AsyncModelsGenerateImagesPatcher
  • _generate_images_wrapper / _async_generate_images_wrapper
  • Output captures image count, sizes, mime types, and safety attrs without storing raw image bytes in spans
  • VCR before_record_response replaces image bytes with a tiny PNG
  • Sync and async test cases validating span structure and metrics

feat(google_genai): add generate_images tracing with Attachment support
d1d1108
Add tracing for the Google GenAI generate_images API (both sync and
async). Generated image bytes are wrapped in Attachment objects so the
SDK uploads them to object storage and the Braintrust UI can render
them, following the same pattern used for input-side inline_data in
both the google_genai and adk integrations.
Key changes:
- ModelsGenerateImagesPatcher and AsyncModelsGenerateImagesPatcher
- _generate_images_wrapper / _async_generate_images_wrapper
- Output includes image metadata (size, mime type, safety attrs) plus
an Attachment per generated image in {"image_url": {"url": attachment}}
- VCR before_record_response sanitizes image bytes in cassettes
- Sync and async test cases validate span structure, metrics, and
Attachment objects

Add tracing for the Google GenAI generate_images API (both sync and async). This includes patchers, input/output serialization, metric extraction, and VCR-based tests with image payload sanitization to keep cassettes small.
Key changes:
  • ModelsGenerateImagesPatcher and AsyncModelsGenerateImagesPatcher
  • _generate_images_wrapper / _async_generate_images_wrapper
  • Output captures image count, sizes, mime types, and safety attrs without storing raw image bytes in spans
  • VCR before_record_response replaces image bytes with a tiny PNG
  • Sync and async test cases validating span structure and metrics

feat(google_genai): add generate_images tracing with Attachment support
d1d1108
Add tracing for the Google GenAI generate_images API (both sync and
async). Generated image bytes are wrapped in Attachment objects so the
SDK uploads them to object storage and the Braintrust UI can render
them, following the same pattern used for input-side inline_data in
both the google_genai and adk integrations.
Key changes:
- ModelsGenerateImagesPatcher and AsyncModelsGenerateImagesPatcher
- _generate_images_wrapper / _async_generate_images_wrapper
- Output includes image metadata (size, mime type, safety attrs) plus
an Attachment per generated image in {"image_url": {"url": attachment}}
- VCR before_record_response sanitizes image bytes in cassettes
- Sync and async test cases validate span structure, metrics, and
Attachment objects
