Summary
This PR updates the server-sdk-typescript SDK to align with the latest OpenAI API specification, addressing gaps identified in the API audit (VAP-11729).
Changes Made
Added
developerrole to OpenAiMessageRole enum (HIGH priority): Required for GPT-5.x and o-series models. The developer role provides system-level instructions that take precedence over user messages.Added deprecation notice for
functionrole (LOW priority): Thefunctionrole is deprecated in favor oftool. Added JSDoc deprecation annotations to guide users toward the recommended approach.Added optional API parameters to OpenAiModel (MEDIUM priority):
seed- For deterministic samplingtopP- Nucleus sampling parameter (alternative to temperature)frequencyPenalty- Penalize repeated tokens (-2.0 to 2.0)presencePenalty- Encourage new topics (-2.0 to 2.0)logprobs- Return log probabilities of output tokenstopLogprobs- Number of top log probabilities to return (0-20)parallelToolCalls- Enable parallel function callingreasoningEffort- Control reasoning depth for o1/o3 reasoning models (low/medium/high)Added OpenAiModelReasoningEffort type: New enum type with
low,medium, andhighoptions for controlling reasoning effort.Test Plan
