Code strings point to a $50 production plan for OpenAI’s API

OpenAI appears to be building a new onboarding flow for its API platform that asks developers to pick one of three plans, Free, Prototype or Accelerate, with the production tier starting at $50. Testingcatalog reported the plans on September 23, based on strings it found. No rollout date is visible yet.

Each tier is named after a stage of a project. Free is for developers trying out API ideas: the API access is free, but it comes only through Codex, and Playgrounds access is limited. Prototype is for lightweight prototypes and small apps. It opens all models, raises usage and widens access to Codex and Playgrounds. Accelerate is for production apps and starts at $50, with all models, higher usage and higher rate limits, the caps on how many requests and tokens an account can push through.

The copy runs from experimenting to prototyping to launching production apps. Testingcatalog reads that as a sign OpenAI wants Platform to become a broader development environment rather than mainly an API dashboard. It is unclear whether developers will be able to deploy or host complete applications there, and the strings confirm the plan structure, not an OpenAI-hosted deployment product.

The hosting reading has some support in what OpenAI already ships. On September 10 it introduced the Agents API, which runs cloud agents on an OpenAI-managed Codex harness, the code that drives the agent’s loop of model calls and tool use, inside OpenAI-hosted sandboxes. So OpenAI already controls more of the runtime behind developer apps.

A year ago, at DevDay on October 6, 2025, OpenAI moved Codex to general availability and launched AgentKit alongside a preview of the Apps SDK. In the new plans, Codex is the way in for the free tier.

Sam Altman posted on September 22: “And then we want you all to come up with great ideas and build them and to get to be happy users. The best ideas will come from you all.” Testingcatalog sees that as fitting the platform reading.

The next likely place for more Platform news is DevDay, which takes place on September 29 in San Francisco. OpenAI has promised technical sessions on APIs and developer tools.
