{
  "provider": {
    "nvidia": {
      "models": {
        "minimaxai/minimax-m2.5": {
          "name": "MiniMax M2.5",
          "options": {
            "reasoningEffort": "high"
          }
        }
      }
    }
  }
}
3. Send a query to the model
4. Observe the reasoning content displayed as plain text with ``` tags
Environment
- OpenCode version: 1.2.15
- Provider: NVIDIA NIM
- Model: minimaxai/minimax-m2.5
- API Endpoint: https://integrate.api.nvidia.com/v1
Possible Solutions
1. Add support for MiniMax reasoning format in the NVIDIA NIM provider
2. Parse ``` content blocks as reasoning_content when detected
3. Add model-specific configuration to handle reasoning format
Additional Context
- Other models like DeepSeek V3.2 work correctly with reasoning
- The issue appears specific to how MiniMax M2.5 formats reasoning output
- NVIDIA NIM API returns reasoning in the message content field with markdown code blocks
