# opencode

opencode is an open-source AI coding agent from Anomaly. It runs as a terminal TUI first, with a desktop app, IDE extensions, and GitHub and GitLab integration around the same core. The agent is free; you connect whatever model provider you already pay for.

## models and pricing

opencode has no fixed model. You bring API keys for any provider, with Claude, GPT, and Gemini named on its homepage. The optional opencode Console adds pay-per-token access to a curated list of 60+ models, but nothing requires it. opencode states that it does not store your code or context data.

## what it’s good at

A plan mode proposes changes before any file is touched, and edits can be undone and redone. `/init` analyzes a project and writes an AGENTS.md so later sessions start informed. The same agent is reachable from the terminal, a desktop app, an IDE, or a CI integration.

## opencode in crystl

opencode runs in a crystl shard with its own model selection, activity visibility, and real approval cards for its tool calls, delivered through a plugin crystl injects into the session. Crystl treats its compatibility as partial because the card only opens on opencode’s own permission event, and a missed answer falls back to opencode’s native prompt.

The profile describes what crystl has tested; it never supplies a command, hook script, or launch setting. Those remain local to the Crystl installation.
