Shipping code faster with o3, o4-mini, and GPT-4.1

CodeRabbit details its multi-model OpenAI pipeline for AI code review: o3 and o4-mini handle reasoning-heavy tasks (multi-line bugs, cross-file architecture issues), while GPT-4.1's 1M token context window powers summarization and routine QA. The system clones repos into sandboxed environments, enriches PR diffs with code history, linters, graph analysis, and issue tickets, then runs recursive multi-pass reviews tailored to each team's standards. A new VS Code integration enables real-time in-editor review alongside the existing PR workflow.
