Provider Configurations

oh-my-opencode-slim uses OpenAI as the default provider. This document shows how to configure alternative providers by editing your plugin config file.

Config File Location

Edit ~/.config/opencode/oh-my-opencode-slim.json (or .jsonc for comments support).

Default: OpenAI

The installer generates this configuration automatically:

{
  "preset": "openai",
  "presets": {
    "openai": {
      "orchestrator": { "model": "openai/gpt-5.4", "variant": "high", "skills": ["*"], "mcps": ["websearch"] },
      "oracle": { "model": "openai/gpt-5.4", "variant": "high", "skills": [], "mcps": [] },
      "librarian": { "model": "openai/gpt-5.4-mini", "variant": "low", "skills": [], "mcps": ["websearch", "context7", "grep_app"] },
      "explorer": { "model": "openai/gpt-5.4-mini", "variant": "low", "skills": [], "mcps": [] },
      "designer": { "model": "openai/gpt-5.4-mini", "variant": "medium", "skills": ["agent-browser"], "mcps": [] },
      "fixer": { "model": "openai/gpt-5.4-mini", "variant": "low", "skills": [], "mcps": [] }
    }
  }
}

Kimi For Coding

To use Kimi, add a kimi preset and set it as active:

{
  "preset": "kimi",
  "presets": {
    "kimi": {
      "orchestrator": { "model": "kimi-for-coding/k2p5", "variant": "high", "skills": ["*"], "mcps": ["websearch"] },
      "oracle": { "model": "kimi-for-coding/k2p5", "variant": "high", "skills": [], "mcps": [] },
      "librarian": { "model": "kimi-for-coding/k2p5", "variant": "low", "skills": [], "mcps": ["websearch", "context7", "grep_app"] },
      "explorer": { "model": "kimi-for-coding/k2p5", "variant": "low", "skills": [], "mcps": [] },
      "designer": { "model": "kimi-for-coding/k2p5", "variant": "medium", "skills": ["agent-browser"], "mcps": [] },
      "fixer": { "model": "kimi-for-coding/k2p5", "variant": "low", "skills": [], "mcps": [] }
    }
  }
}

Then authenticate:

opencode auth login
# Select "Kimi For Coding" provider

GitHub Copilot

To use GitHub Copilot with Grok Code Fast:

{
  "preset": "copilot",
  "presets": {
    "copilot": {
      "orchestrator": { "model": "github-copilot/claude-opus-4.6", "variant": "high", "skills": ["*"], "mcps": ["websearch"] },
      "oracle": { "model": "github-copilot/claude-opus-4.6", "variant": "high", "skills": [], "mcps": [] },
      "librarian": { "model": "github-copilot/grok-code-fast-1", "variant": "low", "skills": [], "mcps": ["websearch", "context7", "grep_app"] },
      "explorer": { "model": "github-copilot/grok-code-fast-1", "variant": "low", "skills": [], "mcps": [] },
      "designer": { "model": "github-copilot/gemini-3.1-pro-preview", "variant": "medium", "skills": ["agent-browser"], "mcps": [] },
      "fixer": { "model": "github-copilot/claude-sonnet-4.6", "variant": "low", "skills": [], "mcps": [] }
    }
  }
}

Then authenticate:

opencode auth login
# Select "github-copilot" provider

ZAI Coding Plan

To use ZAI Coding Plan with GLM 5:

{
  "preset": "zai-plan",
  "presets": {
    "zai-plan": {
      "orchestrator": { "model": "zai-coding-plan/glm-5", "variant": "high", "skills": ["*"], "mcps": ["websearch"] },
      "oracle": { "model": "zai-coding-plan/glm-5", "variant": "high", "skills": [], "mcps": [] },
      "librarian": { "model": "zai-coding-plan/glm-5", "variant": "low", "skills": [], "mcps": ["websearch", "context7", "grep_app"] },
      "explorer": { "model": "zai-coding-plan/glm-5", "variant": "low", "skills": [], "mcps": [] },
      "designer": { "model": "zai-coding-plan/glm-5", "variant": "medium", "skills": ["agent-browser"], "mcps": [] },
      "fixer": { "model": "zai-coding-plan/glm-5", "variant": "low", "skills": [], "mcps": [] }
    }
  }
}

Then authenticate:

opencode auth login
# Select "zai-coding-plan" provider

Mixing Providers

You can mix models from different providers across agents. Create a custom preset:

{
  "preset": "my-mix",
  "presets": {
    "my-mix": {
      "orchestrator": { "model": "openai/gpt-5.4", "skills": ["*"], "mcps": ["websearch"] },
      "oracle": { "model": "openai/gpt-5.4", "variant": "high", "skills": [], "mcps": [] },
      "librarian": { "model": "kimi-for-coding/k2p5", "variant": "low", "skills": [], "mcps": ["websearch", "context7", "grep_app"] },
      "explorer": { "model": "github-copilot/grok-code-fast-1", "variant": "low", "skills": [], "mcps": [] },
      "designer": { "model": "kimi-for-coding/k2p5", "variant": "medium", "skills": ["agent-browser"], "mcps": [] },
      "fixer": { "model": "openai/gpt-5.4-mini", "variant": "low", "skills": [], "mcps": [] }
    }
  }
}

Switching Presets

Method 1: Edit the config file — Change the preset field to match a key in your presets object.

Method 2: Environment variable (takes precedence over config file):

export OH_MY_OPENCODE_SLIM_PRESET=my-mix
opencode

Fallback / Failover

The plugin can automatically fail over from one model to the next when a prompt times out or errors. This is separate from your preset selection — it's a runtime safety net.

How it works:

• Each agent can have a fallback chain under fallback.chains.<agent>
• The agent uses its configured model first
• If that model fails or times out, the manager aborts the session, waits briefly, and tries the next model in the chain
• Duplicate model IDs are ignored — the same model is never retried twice
• If fallback is disabled, tasks run with no failover

Example:

{
  "fallback": {
    "enabled": true,
    "timeoutMs": 15000,
    "retryDelayMs": 500,
    "chains": {
      "orchestrator": [
        "openai/gpt-5.4",
        "anthropic/claude-sonnet-4-6",
        "google/gemini-3.1-pro"
      ],
      "fixer": [
        "fireworks-ai/accounts/fireworks/routers/kimi-k2p5-turbo",
        "openai/gpt-5.4-mini"
      ]
    }
  }
}

Notes:

• Model IDs must use provider/model format
• Chains are per agent: orchestrator, oracle, designer, explorer, librarian, fixer, councillor, council-master
• If an agent has no chain configured, only its primary model is used
