Updated the chat-latest snapshot, which points to the latest model available in ChatGPT for Plus and Pro users. We recommend leveraging GPT-5.6 Sol for production API usage, but feel free to use this model to test the latest improvements for chat use cases. The underlying model snapshot will be regularly updated. Read more here.
公式の更新履歴を見る ↗Fast mode now supports long-context requests for GPT-5.6 Sol, GPT-5.6 Terra, and GPT-5.6 Luna. As of today, long-context prompts exceeding 272K tokens can run in Fast mode, delivering speeds up to 2.5× faster than the Standard tier. See pricing details.
公式の更新履歴を見る ↗Customers can now filter and group data by API key in the Usage and Costs dashboards. The Usage API and Costs API also support the API key dimension for programmatic reporting and analysis.
公式の更新履歴を見る ↗Starting July 30, GPT-5.6 Luna costs 80% less, while GPT-5.6 Terra costs 20% less. See pricing details. We're also introducing Fast mode in the API, which replaces our Priority Processing offering. For GPT-5.6 Sol, Fast mode now delivers up to 2.5× faster speeds than standard processing at twice the price. This change is backward compatible: requests tagged priority will automatically use Fast mode.
公式の更新履歴を見る ↗Released the official OpenAI Terraform provider for managing OpenAI API Platform resources as infrastructure as code. Provision and manage projects, users, groups, roles, access assignments, service accounts, certificates, invitations, and project-level rate limits. Use standard Terraform workflows to review and apply changes, import existing resources, and detect and reconcile configuration drift. Install the provider from the Terraform Registry.
