Local Ollama models not included in model listing, breaking plugin model discovery #12243

Description

When Ollama is registered as a provider in opencode.json, the SDK's model listing does not include Ollama models. The provider appears in the "connected" list, but the models object remains empty for Ollama.

This causes plugins (e.g., oh-my-opencode) that rely on model discovery to fail when routing tasks to local Ollama models.

What works:

• Ollama provider is recognized (appears in connected array)
• Direct model usage works when explicitly specified by a plugin
• Ollama's own API responds correctly (GET /v1/models returns all models)

What doesn't work:

• Model listing never includes Ollama models
• Plugin caches (provider-models.json) stay empty for Ollama
• Category-based delegation in plugins can't discover Ollama models

Plugins

oh-my-opencode 3.2.3

OpenCode version

1.1.51

Steps to reproduce

1. Install and start Ollama:

   ollama serve
   ollama pull ministral-3:14b-32k-agent

2. Configure Ollama provider in ~/.config/opencode/opencode.json:

   {
     "provider": {
       "ollama": {
         "name": "Ollama",
         "npm": "@ai-sdk/openai-compatible",
         "options": { "baseURL": "http://localhost:11434/v1" },
         "models": {
           "ministral-3:14b-32k-agent": { "name": "ministral-3:14b-32k-agent" }
         }
       }
     }
   }

3. Start OpenCode and check provider cache:

   cat ~/.cache/oh-my-opencode/provider-models.json

4. Observe: "models": {} — Ollama models are missing despite provider being connected.

5. Verify Ollama API works directly:

   curl http://localhost:11434/v1/models
   # Returns: { "data": [{ "id": "ministral-3:14b-32k-agent", ... }] }

  "models": {},
  "connected": ["openai", "google", "anthropic", "opencode", "ollama"],
  "updatedAt": "2026-02-05T05:24:52.824Z"
}

Note: ollama is in connected but models is empty.

Operating System

Linux

Terminal

SSH

Additional Notes

Current workaround: Manually query ollama list and inject models into the provider cache. This is fragile — gets overwritten on provider refresh.

Suggested approach: When a provider uses npm: "@ai-sdk/openai-compatible" and has a baseURL, query GET {baseURL}/models to discover available models. Ollama (and LM Studio, etc.) all support this OpenAI-compatible endpoint.

Impact: Any plugin relying on model discovery cannot use local models without manual workarounds. This affects the growing ecosystem of users running local models for cost savings and privacy.
