MiniMax M2 <think> tags

Question

Does opencode support rendering tags in the UI like for example Claude Code?

This issue might be a duplicate of existing issues. Please check:

• MiniMax-M2 reasoning content not properly handled in OpenAI-compatible mode, should we support this ? #3555: Deals specifically with MiniMax-M2 reasoning content and tags not being properly handled in OpenAI-compatible mode (closed)
• [Feature Request] Add support for using thinking tags in local models #1528: General feature request for better support of thinking tags in local models with UI separation

Feel free to ignore if none of these address your specific case.

I'm using Minimax M2 on both their official API and locally hosted with llama.cpp. Both rendering the reasoning blocks properly in opencode, no think tags appear in the response texts. I set reasoning true in opencode.json

"models": {
        "minimax-m2": {
          "name": "minimax-m2",
          "tool_call": true,
          "reasoning": true,
          "cost": {
            "input": 0.10,
            "output": 1.20
          },
          "options": {
            "num_ctx": 131072,
            "temperature": 1.0,
            "top_p": 0.95,
            "top_k": 40
          }
        },

CORRECTION: I am using OpenCode with Minimax-M2 locally hosted only, not the official API. Using Minimax M2 official API with Claude Code.

[rekram1-node]

what is codex relay?

Oh, it means third-party intermediary website. It work well with the Codex CLI, but encountered some issues in OpenCode (can't render think blocks).

@aaronnewsome Does tool calling work with OpenCode + local MiniMax-M2? I tested them but OpenCode doesn't parse/understand MiniMax's way of tool call (XML)

[aaronnewsome]

I use OpenCode heavily with Minimax-M2 hosted locally. Over many weeks of heavy daily usage, I see no major issues and it runs very stable, much better than GLM 4.5. When someone says it doesn't work, my first two questions are, what are you serving it with and what chat template are you using. Details of my setup are here

I'm using Minmax through nVidia NIM and I can see the tags showing as <think> and I think I saw them as _think_ one time. Seems to me there is a escaping/encode issue with some providers.

V1.0.134 - Windows 10 - Windows Terminal

Same issue. I suspect providers like OpenRouter run extra post-processing & parsing layers behind the scenes, which is why their outputs stay intact - unlike what I see when running the same model locally vLLM

[rekram1-node]

the think tags are being sent as assistant messages not reasoning thats why opencode renders them as such
