opencode v2 support

Would be nice if someone could add V2 support alongside V1 support.

V2 support is now in progress on the v2 branch, with the existing V1 implementation kept intact.

The initial implementation uses OpenCode 2’s public provider and integration APIs. We’ve verified the core discovery flow against OpenCode 2.0.14: registering a provider without seed models, fetching its OpenAI-compatible /models endpoint, and exposing the discovered models in the runtime.

This is still development work, not a published V2 release or full feature parity with V1. The V2 implementation is isolated in src-v2/; metadata enrichment, caching, and release packaging still need further work.

We’ll keep this issue open to track V2 support and share installation instructions once there’s a release ready for testing.

Thank you for raising this issue and for helping move the OpenCode v2 support forward.

OpenCode v2 support is now available in v1.6.0 as a beta feature. The package includes both the existing OpenCode v1 integration and the new OpenCode v2 adapter.

When using OpenCode v2, please update your configuration to the v2 format:

• Use plugins instead of plugin.
• Use providers instead of provider.
• Use each provider's package instead of npm.
• Move provider options under settings.
• Configure discovery under providers.<id>.settings.modelsDiscovery.

Please see the V1-to-V2 migration guide for examples and details.

Once the V2 implementation and its test coverage are more mature, OpenCode v2 will become the primary supported host in the upcoming v2.0 release.

Thank you again for your patience and contribution.

Update for the current release status:

OpenCode v2 support has been available as a beta feature since v1.6.0, and the current release is v1.7.0. The package includes both the existing V1 integration and the V2 adapter.

For OpenCode v2, use:

• plugins instead of plugin;
• providers instead of provider;
• each provider's package instead of npm;
• provider options under settings;
• discovery under providers.<id>.settings.modelsDiscovery.

V2 now also recognizes provider packages containing anthropic-compatible, including @opencode/ai/providers/anthropic-compatible, when the backend exposes an OpenAI-compatible model-list endpoint.

See the V1-to-V2 migration guide and the V2 configuration guide for current examples. V2 remains beta, so this issue will stay open for ongoing compatibility feedback.
