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

Vendo is an open source customization layer that lets customers build their own features and micro-apps directly on top of a product. Users describe what they need, and the interface assembles it live into persistent apps with UI, data, actions, automations, and state rather than returning a one-off answer. Vendo can generate on-demand dashboards, standing automations, and workflows connected to tools such as Gmail, Slack, and GitHub. One initialization command reads the host product’s repository to learn its components, colors, API tools, and permission rules, so generated experiences follow the existing brand and stay within each signed-in user’s access. Apps can appear as overlays, chat sidebars, full panels, or components remixed into the product, and the same experiences can also open through Claude and ChatGPT or run on a schedule. Generated experiences run sandboxed, and the system shows changes before writing them and checks its own work.
