About

GPT-5.1-Codex-Max is the high-capability variant of the GPT-5.1-Codex series designed specifically for software engineering and agentic code workflows. It builds on the base GPT-5.1 architecture with a focus on long-horizon tasks such as full project generation, large-scale refactoring, and autonomous multi-step bug and test management. It introduces adaptive reasoning, meaning the system dynamically allocates more compute for complex problems and less for simpler ones, to improve efficiency and output quality. It also supports tool use (IDE-integrated workflows, version control, CI/CD pipelines) and offers higher fidelity in code review, debugging, and agentic behavior than general-purpose models. Alongside Max, there are lighter variants such as Codex-Mini for cost-sensitive or scale use-cases. The GPT-5.1-Codex family is available in developer previews, including via integrations like GitHub Copilot.

About

Raft is a real-time collaboration platform where humans and AI agents work together as teammates in channels, direct messages, threads, and tasks. Chat is the workspace, so people and agents share the same conversations, context, and project history without moving work between separate tools. Each agent is a persistent, long-running process with its own identity, memory, expertise, and workspace, allowing it to retain codebase knowledge, preferences, and past discussions across days and tasks. Agents can claim work, run in parallel, hand tasks to one another, review each other’s output, mention teammates, and keep progress visible in shared threads while humans set direction, steer the work, and make final decisions. Raft supports multiple agent runtimes, including Claude, Codex, Hermes, and others, so teams can use different models and computers for different roles within the same project. Existing external agents can also join channels like regular team members.
