[Bug] "Provider returned error" consistently occurs with Kimi K2.5 via OpenCode Go on Windows

Description

Environment Information
Client: OpenCode (Windows Desktop Client, latest version))

Model Provider: OpenCode Go

Model: Kimi K2.5

Timestamp: March 8, 2026, 10:34 PM (CST)

Describe the bug
When sending a prompt to the Kimi K2.5 model through the OpenCode Go provider on the Windows desktop client, the application immediately returns a red error box stating "Provider returned error". This happens consistently and prevents any response from being generated.

Session Example (The Prompt that triggered the error)
User Input:

"目前的三个模板，对不对？没有yaml信息？我觉得在工作流加上，如无特殊说明，尽量用中文写作。标题为中文，但是要有alias，通常是英文或者别的语言的翻译以及一些真的缩写、别名等。不需要日期和tag。"

Expected Result:
The model should analyze the prompt and provide a response or suggestion regarding the template structure.

Actual Result:
The UI shows: Provider returned error (Build: Kimi K2.5).

Plugins

This also happens on Linux with opencode CLI with OpenCode Go's Kimi K2.5. All other models from OpenCode Go works file as far as I've tested.

Same in MacOS

same here!

I am seeing the same error on macOS CLI

Same in zeroclaw in docker.
Also happens when using minimax-m2.7 though the error is less frequent

Kimi has prompt token issue but minimax-m2.7 has input token issue.

Experiencing same issue for Mimo v2 pro free by Opencode Free, and additional "expected 'id' to be a string" error for Kimi K2.5 via Nvidia API since OpenCode1.2.24.

This has been plaguing me out of random, its slowing my work and is getting annoying

same with "Nemotron 3 Super Free" can anyone show some more about this error? HOW CAN i FIXIT?

Same here but with Kimi-2.6 (OpenCode Go)

today use Kimi-2.6 (OpenCode Go) or Kimi-2.5 (OpenCode Go) return same wrong,
but use nvdia Kimi-2.5 is work ok

I get this issue as well for the latest Kimi K2.6

The MCPs are the problem.

#23887 (comment)

Chances are there is an mcp or tool causing an error the error is a little too generic
