About
GPT-5.3-Codex is OpenAI’s most advanced agentic coding model, designed to handle complex professional work on a computer. It combines frontier-level coding performance with advanced reasoning and real-world task execution. The model is faster than previous Codex versions and can manage long-running tasks involving research, tools, and deployment. GPT-5.3-Codex supports real-time interaction, allowing users to steer progress without losing context. It excels at software engineering, web development, and terminal-based workflows. Beyond code generation, it assists with debugging, documentation, testing, and analysis. GPT-5.3-Codex acts as an interactive collaborator rather than a single-turn coding tool.

About
Slack Code is a collaborative coding experience that brings teammates and AI agents together to build software in the open. Mentioning an agent can start a temporary code channel for a specific task, giving the team a dedicated place to follow the work, provide direction, review changes, and approve the result without cluttering regular channels. Agents begin with the conversations and knowledge they are permitted to access, helping them work with useful team context from the start. Users can describe what they want built and let an agent produce working code while everyone follows along, weighs in, and decides what ships. Code channels archive automatically when the task is complete, while their context remains searchable for future reference. Agents are organized in the Agents tab, where users can check sessions, monitor live status, and see when input is needed. Smarter threads create clearer titles so previous work is easier to find and resume.
