OpenAI makes its Jev competitor widely available as decision model competition heats up

What happened: OpenAI made its Decisions API model widely available to all customers, entering the market for fast, cheap decision models led by TypeSafe's Jev. The API was announced at OpenAI's developer day on September 29. Key numbers: TypeSafe is valued at $7.6 billion. Why it matters: Developers have used decision models to replace LLMs in workflows at lower cost and higher speed, and OpenAI built its version by reconfiguring ChatGPT Luna rather than training a dedicated model. TypeSafe's offerings remain the most widely queried on OpenRouter.
