About OpenAI

OpenAI develops AI models, applications and developer services. Its public materials describe research and deployment work, with model documentation covering text, code, images, audio and reasoning. The company's product and model-family names identify different layers: an application, a coding tool and an API model are separate objects to record.

Focus

  • AI research and model development
  • Developer APIs
  • Applications and coding tools

Projects and interfaces

  • GPT model families

    model families

    Model lines exposed through OpenAI's documented interfaces, with capabilities and lifecycle conditions specific to each version.

  • ChatGPT and Codex

    applications and tools

    OpenAI products listed separately from the underlying model catalog.

Scope and limitations

  • API model IDs, application subscriptions and coding-tool access have distinct version and access conditions.

Official references

Models

124 named catalog records. These are name and distribution records, not a count of distinct model architectures.
