const adapter = new OpenCodeAdapter();

// Run with default model

const result2 = await adapter.run("analyze complexity", { model: "opus" });

const models = await adapter.getSupportedModels();

Properties

| Property | Value | |---|---| | name | "opencode" | | costTier | "free" (BYOK — uses your own API keys) | | multiModel | true |

CLI Command

opencode run <prompt> --format json [-m <provider/model>]

Output is NDJSON. The parser extracts content from text events and model info from step_start metadata.

Model Aliases
