GPT 5.1 Codex

By OpenAI
Model family: GPT
This variant is tuned for software workflows. It plans changes, searches a repo, and produces reviewable artifacts like unified diffs, migrations, and test suites instead of free-form prose. It follows instructions closely, keeps multi-file dependencies straight, and calls tools like linters, test runners, or build scripts in loop. Outputs can be schema-true JSON, patches, or step plans that CI can consume. It is well suited for IDE copilots, refactors, doc sync, and policy-aware automation where format and reliability matter.
