OpenAI Preset

openai is the default generated preset. The installer builds both openai and opencode-go; OpenAI is the one that runs unless you pick the other.

Install with OpenAI Active

bunx oh-my-opencode-slim@latest install

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 openai

See Preset Switching for the full runtime switching workflow.

Bundled Model Mapping

The generated openai preset assigns each specialist an OpenAI model:

Agent	Model
Orchestrator	openai/gpt-5.6-terra (xhigh)
Oracle	openai/gpt-5.6-sol (xhigh)
Librarian	openai/gpt-5.6-luna (low)
Explorer	openai/gpt-5.6-luna (low)
Designer	openai/gpt-5.6-luna (medium)
Fixer	openai/gpt-5.6-luna (xhigh)

Generated Config Shape

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

        "mcps": []
      },
      "librarian": {
