GitHub Copilot: GPT-5.1 Codex preview, Spaces sharing, and model retirements
Overview
GitHub Copilot added a public preview of GPT-5.1-Codex-Max across web, IDE, mobile, and CLI (Enterprise/Business must enable it), made Spaces shareable publicly or per-user with a code-viewer add-to-Space flow, and refined the VS model picker. Older OpenAI/Anthropic/Google models were retired with suggested replacements, agents gained mission control and skills with broader IDE coverage, and knowledge bases fully sunset in favor of Spaces.
