OpenCode Go Preset

opencode-go runs the Pantheon agents on OpenCode Go models instead of the default OpenAI setup.

The installer builds both openai and opencode-go. OpenAI stays active unless you choose OpenCode Go at install time or switch to it later.

Because the opencode-go Orchestrator model (minimax-m3) is not multimodal, installing with --preset=opencode-go also enables the Observer agent and configures it with opencode-go/mimo-v2.5 (a native omnimodal model) 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/minimax-m3 (max)
Oracle	opencode-go/qwen3.7-max (max)
Librarian	opencode-go/deepseek-v4-flash (high) + MCPs
Explorer	opencode-go/deepseek-v4-flash (max)
Designer	opencode-go/kimi-k2.7-code (medium)
Fixer	opencode-go/deepseek-v4-flash (high)
Observer	opencode-go/mimo-v2.5 (max)

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/minimax-m3",
        "variant": "max"
      },
      "oracle": {
        "model": "opencode-go/qwen3.7-max",
        "variant": "max"
      },
      "librarian": {
        "model": "opencode-go/deepseek-v4-flash",
        "variant": "high",
        "mcps": ["websearch", "context7", "gh_grep"]
      },
      "explorer": {
        "model": "opencode-go/deepseek-v4-flash",
        "variant": "max"
      },
      "designer": {
        "model": "opencode-go/kimi-k2.7-code",
        "variant": "medium"
      },
      "fixer": {
        "model": "opencode-go/deepseek-v4-flash",
        "variant": "high"
      },
      "observer": {
        "model": "opencode-go/mimo-v2.5",
        "variant": "max"
      }
    }
  }
}

Skill Reference

This preset defines per-agent skills and mcps via generateLiteConfig. The generated config includes skills: ["*"] for Orchestrator and agent-specific MCP lists (e.g., Librarian gets websearch, context7, gh_grep).
