Before you mark this PR as ready for review, make sure that you have:

  • Added a solid test coverage and/or screenshots from doing manual testing
  • Done a self-review taking into account security and performance aspects
  • Aligned any UI changes with the UI checklist

Per Opencode's website:

Zen gives you access to a curated set of AI models that OpenCode has tested and benchmarked specifically for coding agents. No need to worry about inconsistent performance and quality, use validated models that work.

  • Testing select models and consulting their teams
  • Working with providers to ensure they're delivered properly
  • Benchmarking all model-provider combinations we recommend

There are so many models available, but only a few work well with coding agents. Most providers configure them differently with varying results.

The models under the Zen umbrella typically have a more reliable token(s) per second speed with minimal outages. The opencode ecosystem has improved my workflow if not many others' !

For other curious people, OpenCode Go can also be used by configuring the Go API URL and by configuring a Custom Model for MiniMax M2.7 (the other Go models are also available in Zen and are included in the default provider config):

  "language_models": {
    "opencode": {
      "api_url": "https://opencode.ai/zen/go",
      "available_models": [
        {
          "name": "minimax-m2.7",
          "max_tokens": 200000,
          "max_output_tokens": 128000,
          "protocol": "openai_chat",
        }
      ]
    },
  }

Attempting to use non-Go models will fail with an language model provider API endpoint not found error.
