OpenAI's Decisions API available through Vercel AI Gateway and LangSmith LLM Gateway

Vercel says OpenAI's Decisions API is live on its AI Gateway, answering yes/no, choice, and score questions for any decision model.

Developers reach it through the model identifier openai/gpt-6-luna-decisions. The announcement came from Vercel's developer account on X, and no independent confirmation, pricing, or performance figures have been reported.

LangChain says its LangSmith LLM Gateway now supports the OpenAI Decisions API for low-latency agent inference. The gateway adds centralized controls for model fallbacks, data redaction policies, and spend limits.
