Harness · sst/opencode
OpenCode
A CLI-first, provider-agnostic coding agent supporting a wide range of model providers. An open-source harness that already appears on a proprietary coding-agent leaderboard — a natural bridge entrant.
aeqi builds one of the harnesses measured here. This board is in method preview and pre-registration — no performance scores are published yet, and we lead with our own losses, not our wins. Read the method & charter →

The facts
- Maintainer
- sst
- Source
- sst/opencode
- License
- MIT
- Category
- Coding harness
- Headless run
- Yes — `opencode run --format json` (mind the open non-interactive edge cases)
- Native OpenRouter
- — can be pinned to one shared model
- Determinism notes
- Official container image + git tag to pin. Isolate per run — it has a persistent-server mode that carries state.
Where it sits
Performance scores land here only with published traces, under the pre-registered method. Until then, this profile is the fair-run readiness check: can we start OpenCode headless and pin it to one shared model to isolate the scaffold?
