OpenCode is an open-source AI coding agent from Anomaly, the team behind SST. It runs in the terminal, a desktop app, or an IDE extension, connects to 75+ model providers through Models.dev — frontier APIs and local models alike — and stores none of your code on external servers. The optional paid Zen gateway adds a curated, benchmarked model set under one bill.
