Defined in: src/batteries/llm/openai_responses/types.ts:78

Discriminated union of content block shapes accepted by the OpenAI Responses input item content array (and, per the API reference, also the shape a function_call_output.output array entry may take).

Remarks

input_audio is deliberately absent — confirmed against the openai SDK's own type definitions (ResponseInputContent has no audio member). Audio media routes through unsupportedMediaPolicy, unlike openai_chat_completions.

input_file.file_data uses a full data:<mime>;base64,<b64> data URI (not bare base64) — confirmed via a live probe against the real Responses API (see the battery's design notes). filename is required alongside file_data.
