🐛 AI_APICallError: No endpoints found that support tool use

Environment

• OS: macOS 15.5
• OpenCode Version: 0.3.8
• Provider: OpenRouter
• Model: tngtech/deepseek-r1t2-chimera:free, moonshotai/kimi-k2:free

🔍 Description

When initiating a session using OpenRouter as the provider, OpenCode returned the following error:

AI_APICallError: No endpoints found that support tool use. To learn more about provider routing, visit: https://openrouter.ai/docs/provider-routing

This happened after the session was created and message parts were successfully updated. The error seems related to the selected model not supporting the tool use feature.

It seems like deepseek-r1t2-chimera:free is misconfigured on models.dev, the model is setup with tool_usage support while https://openrouter.ai/api/frontend/models return that the model doesn't support tool.
You can workaround it for now by updating your opencode config with:

  "provider": {
    "openrouter": {
      "models": {
        "tngtech/deepseek-r1t2-chimera:free": {
          "name": "DeepSeek R1T2 Chimera (free)",
          "tool_call": false,
          "reasoning": true
        }
      }
    }
  }

same here for Kimi K2 free

[frank-besson]

I've also noticied this for most models on OpenRouter. I'm making sure to crosscheck models.dev to see if the model supports tooling

just paid models work

closing as there's nothing we can do about this - feel free to continue convo

Hey everyone, for anyone coming across these issues, I've opened 2 pull requests on the models.dev repo to address the problems with these free OpenRouter models.:

• Fix for tngtech/deepseek-r1t2-chimera:free: fix: Disable tool_call for deepseek-r1t2-chimera:free models.dev#80
• Added support for Kimi-K2:free: feat: add kimi-k2:free model models.dev#81**

Hope this helps!
