Patch Changes

• provider/openai: Safe practice to include filename and fileExtension to avoid experimental_transcribe fails with valid Buffer

Patch Changes

• provider/openai: Make file_citation annotation fields optional for responses api compatibility

Patch Changes

• provider/openai: Support websearch tool results without query property

• provider/openai: Do not set response_format to verbose_json if model is gpt-4o-transcribe or gpt-4o-mini-transcribe

  These two models do not support it:

• provider/openai: Exclude gpt-5-chat from reasoning model

Patch Changes

• openai, azure: Add configurable file ID prefixes for Responses API

  • Added fileIdPrefixes option to OpenAI Responses API configuration

  • Azure OpenAI now supports assistant- prefixed file IDs (replacing previous file- prefix support)

  • OpenAI maintains backward compatibility with default file- prefix

  • File ID detection is disabled when fileIdPrefixes is undefined, gracefully falling back to base64 processing

• provider/openai: Add support for prompt_cache_key

• provider/openai: Add support for safety_identifier

• openai: Add missing file_search_call handlers in responses streaming

Patch Changes

• provider/openai: Add code interpreter tool (responses api)

  Move Image Model Settings into generate options

  Image Models no longer have settings. Instead, maxImagesPerCall can be passed directly to generateImage(). All other image settings can be passed to providerOptions[provider].

  Before

  await generateImage({
    model: luma.image('photon-flash-1', {
      maxImagesPerCall: 5,
      pollIntervalMillis: 500,
    }),
    prompt,
    n: 10,
  });

  After

  await generateImage({
    model: luma.image('photon-flash-1'),
    prompt,
    n: 10,
    maxImagesPerCall: 5,
    providerOptions: {
      luma: { pollIntervalMillis: 5 },
    },
  });
