Patch Changes

• 14c196a: Avoid empty structured-output answers from Baseten's DeepSeek V4 Pro 0813 when reasoning is enabled. Fall back to JSON prompt instructions while keeping reasoning and SDK output validation, and report the fallback through request transformation warnings.

• 98eb47b: fix(openai,openai-compatible): surface refusal logprobs and openai-compatible refusals

  @ai-sdk/openai: Chat Completions responses that contain a refusal can return logprobs.refusal next to logprobs.content. The provider previously read only logprobs.content, so providerMetadata.openai.logprobs was empty or missing for refusals. Refusal logprobs are now included in emission order (content logprobs followed by refusal logprobs) in both generateText and streamText.

  Streaming logprobs are now collected across all chunks in streamText: previously only the logprobs of the last streamed chunk were reported. This applies to content logprobs as well, so providerMetadata.openai.logprobs now contains the logprobs of every streamed token instead of only the last chunk's tokens. Explicitly empty logprobs (logprobs: { content: [], refusal: null }) are reported as an empty array, as before.

  A refusal that arrives in the same streamed chunk as the finish_reason is now taken into account: such a response is reported with a content-filter finish reason instead of stop.

  @ai-sdk/openai-compatible: Chat Completions responses that carry message.refusal (non-streaming) or delta.refusal (streaming) were ignored, so providers such as OpenAI served through createOpenAICompatible lost the refusal text and reported an empty stop response. Refusals are now returned as text content after any content text, and a non-empty refusal with a stop finish reason is reported as a content-filter finish reason. This also applies when the refusal and the finish reason arrive in the same streamed chunk. Non-string refusals (for example refusal: false from servers that use booleans) are ignored instead of failing the response.
