Reason is a state-of-the-art coding for cost efficiency.
We scored higher than harnesses like Codex & Pi on benchmarks like Terminal Bench 4.0 and DeepSWE while being 22% cheaper.
Reason can work in the cloud or locally. Give it a task and it writes code, runs tests and opens a pull request. Use Reason from the Mac app, terminal, web or Slack, with your choice of models and connected subscriptions. Start free on your own computer or cloud!

The screen recording attached to a PR caught my eye. Seeing what the agent actually did in the app should help a reviewer understand the change before going through the diff.
@oleksii_sekundant Exactly, visual verification native to every PR where applicable.
Love to see your LLM on https://gertlabs.com/rankings
@jay_janarthanan1 thanks Jay! Reason is the coding agent around the model, rather than a model we trained. Do you support evaluating agent harnesses too? We publish our benchmark runs so people can inspect the results.
