About
GPT-5.3-Codex-Spark is an ultra-fast coding model designed for real-time collaboration inside Codex. Built as a smaller version of GPT-5.3-Codex, it delivers over 1000 tokens per second when served on low-latency Cerebras hardware. The model is optimized for interactive coding tasks, enabling developers to make targeted edits and see results almost instantly. With a 128k context window, Codex-Spark supports substantial project context while maintaining speed. It focuses on lightweight, precise edits and does not automatically run tests unless prompted. Infrastructure upgrades such as persistent WebSocket connections significantly reduce latency across the full request-response pipeline. Released as a research preview for ChatGPT Pro users, Codex-Spark marks the first milestone in OpenAI’s partnership with Cerebras.

About
OpenAI Dots are always-on AI agents designed to take ownership of ongoing projects and proactively move work forward between conversations. Powered by GPT-6 Astra, each dot can start with context from a user's ChatGPT memory and use Codex, connected applications, and its own cloud computer to complete tasks. Users can assign a dot a responsibility, specify what it should focus on, and determine which applications and information it can access. Dots can identify next steps, monitor changing information, perform work, and bring completed materials or important decisions back to the user for review. They can support workflows such as financial analysis, presentations, sales evaluations, software development, API migrations, content creation, and project monitoring. Users remain in control through configurable permissions, Custom Rules, approval requirements, action reviews, and the ability to redirect or pause a dot at any time.
