Praxis Chat

Big models code well, but running agents on them all day gets expensive. Small models are cheap, but they guess. Praxis closes the gap: it gives the model an exact map of your code and checks every answer before you see it. On SWE-bench Verified, Claude Haiku 5.5 with Praxis resolved 77 of 100 tasks, against 80 for Sonnet 5.5, at about one-eleventh the cost. Hand repetitive work to agents on your own keys, at the provider’s price. Your code stays on your PC.
