OpenAI API — August, 2026

August 1, 2026

The Daybreak program's introduction of two distinct access tiers: Daybreak Blue for general defensive security tasks and Daybreak Red for advanced exploit validation and red teaming. These specialized tiers offer unique models for enhanced security operations. Significant performance improvements include Fast mode support for long-context requests (over 272K tokens) on GPT-5.6 Sol, Terra, and Luna, delivering up to 2.5x faster speeds. Additionally, API key filtering and grouping capabilities are available in Usage and Costs dashboards for better programmatic reporting.

Changed

Start with Daybreak Blue for most defensive security work. It provides access to general-purpose models such as GPT-5.6 Sol for vulnerability discovery, secure code review, detection engineering, incident response, malware analysis, and patch validation. Read more here.
Daybreak Red provides separately approved access to purpose-trained models such as GPT-5.6 Cyber for authorized vulnerability reproduction, exploit validation, penetration testing, red teaming, and complex system analysis.
These models require separate approval and provisioning. You can apply to join the Daybreak program here. More details on pricing here.
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.
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.
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.

Fixed

Daybreak now offers two access tiers for approved defenders: Daybreak Blue and Daybreak Red. Use them to move from security findings to validated fixes in explicitly authorized engagements.
