MiniMax-M3 no longer shows model thinking/reasoning output and behavior changed #31569
Description

Description
Hi, I’m using MiniMax-M3 with opencode. Previously, I was able to see the model’s thinking/reasoning-style output while it was working on a task, including how it was approaching the problem.
Recently, this stopped working. Now I only see the final/normal response, and the model behavior also feels different compared to before.
I’m not sure whether this is caused by:
- an opencode update
- a MiniMax API/provider change
- a config issue
- reasoning/thinking output being disabled or no longer supported
- the provider adapter not passing through the thinking/reasoning content
Expected behavior
When using MiniMax-M3 in opencode, I expected to see the same thinking/reasoning/progress output that was visible before, or at least some indication of how the model is approaching the task.
Actual behavior
The thinking/reasoning output is no longer shown. The response behavior also seems different from previous usage.
Steps to reproduce
- Configure MiniMax-M3 as a provider in opencode.
- Run a task that previously showed model thinking/progress.
- Observe that the thinking/reasoning output is no longer visible.
My provider config
{
"provider": {
"minimax": {
"npm": "@ai-sdk/anthropic",
"options": {
"baseURL": "https://api.minimax.io"
},
"models": {
"MiniMax-M3": {
"name": "MiniMax-M3"
}
}
}
}
}Note: I’m using the API key through environment variables, not hardcoding it in the config.
Environment
- OS: macOS Tahoe / Apple Silicon
- opencode version:1 .16.2
- Node/Bun version:v22.18.0
- MiniMax model: MiniMax-M3
- Provider package:
@ai-sdk/anthropic
Question
Is this expected behavior now, or is there a config/provider setting required to enable the thinking/reasoning output again?
If this is caused by a provider/API change, it would be helpful to document whether MiniMax-M3 still supports visible reasoning/thinking output inside opencode.

This was fixed by #31426 and shipped in OpenCode v1.17.0. That PR enabled
thinking: { "type": "adaptive" }for MiniMax M3 on the direct Anthropic-compatible route and added thenone/thinkingvariants. This report was filed against v1.16.2, before the fix was released.The custom provider configuration in the report also uses
https://api.minimax.ioas its AnthropicbaseURL; MiniMax documentshttps://api.minimax.io/anthropic, and OpenCode's built-in provider already uses the correct Anthropic endpoint. The built-in provider should be used without overriding that URL.For completeness, #38330 later corrected MiniMax M3 variant bodies specifically for NVIDIA and Lilac. It intentionally preserves the direct MiniMax behavior added by #31426.
Closing as completed.
