GPT-5.1-Codex

GPT-5.1-Codex is OpenAI's agentic coding model, optimized for long-running software engineering tasks such as feature development, refactoring, debugging, and code review in Codex-like environments. It is distinct from GPT-5.1 in being purpose-built for developer workflows rather than general-purpose conversation. Source: supabase.
