OpenCode Go Preset

opencode-go is a bundled generated preset for users who want to run the Pantheon agents through OpenCode Go models instead of the default OpenAI setup.

The installer generates both openai and opencode-go presets. OpenAI stays active by default unless you select OpenCode Go during install or switch to it later.

Because the opencode-go preset uses GLM-5.1 for Orchestrator and GLM is not multimodal, installing with --preset=opencode-go also enables the Observer agent and configures it with opencode-go/kimi-k2.6 for visual analysis.

Install with OpenCode Go Active

bunx oh-my-opencode-slim@latest install --preset=opencode-go

Then authenticate and refresh models:

opencode auth login
opencode models --refresh

Switch at Runtime

If both presets are already in your config, switch from inside OpenCode:

/preset opencode-go

See Preset Switching for the full runtime switching workflow. If you originally installed with the default OpenAI preset, also add "disabled_agents": [] to your config and restart OpenCode so Observer is available before switching to opencode-go.

disabled_agents is global, not per-preset. If you later switch back to OpenAI and restart while keeping "disabled_agents": [], Observer will remain enabled and use the default Observer model unless you configure one explicitly.

Bundled Model Mapping

The generated opencode-go preset maps each specialist to a model tuned for its role:

Agent	Model
Orchestrator	opencode-go/glm-5.1
Oracle	opencode-go/deepseek-v4-pro (max)
Council	opencode-go/deepseek-v4-pro (high)
Librarian	opencode-go/minimax-m2.7
Explorer	opencode-go/minimax-m2.7
Designer	opencode-go/kimi-k2.6 (medium)
Fixer	opencode-go/deepseek-v4-flash (high)
Observer	opencode-go/kimi-k2.6

Generated Config Shape

Your generated config includes opencode-go under presets and activates it by setting the top-level preset field:

{
  "preset": "opencode-go",
  "disabled_agents": [],
  "presets": {
    "opencode-go": {
      "orchestrator": { "model": "opencode-go/glm-5.1" },
      "oracle": {
        "model": "opencode-go/deepseek-v4-pro",
        "variant": "max"
      },
      "council": {
        "model": "opencode-go/deepseek-v4-pro",
        "variant": "high"
      },
      "librarian": { "model": "opencode-go/minimax-m2.7" },
      "explorer": { "model": "opencode-go/minimax-m2.7" },
      "designer": {
        "model": "opencode-go/kimi-k2.6",
        "variant": "medium"
      },
      "fixer": {
        "model": "opencode-go/deepseek-v4-flash",
        "variant": "high"
      },
      "observer": { "model": "opencode-go/kimi-k2.6" }
    }
  }
}
