[Bug] Persistent ProviderInitError on Apple Silicon Mac Despite Clean Install

[manao29]

Hello, I am experiencing a persistent ProviderInitError when running opencode on my Apple Silicon Mac. The error occurs immediately upon sending the first message in the interface.

I have already gone through extensive troubleshooting, but the issue remains unchanged.

Error Message:

failed to send message: POST "http://127.0.0.1:xxxxx/session/..." 400 Bad Request
{"name":"ProviderInitError", "data":{"providerID":"opencode"}}
System Information:

macOS Version: (26.0.1)

Hardware: (arm64)

Node.js Version: v20.19.5 (managed by nvm)

npm Version: (10.8.2)

Troubleshooting Steps Performed:

I have tried all ofthe following steps, but the error persists in all scenarios:

Performed a complete wipe and re-installation multiple times (including deleting ~/.opencode and ~/.config/opencode directories and clearing npm cache).

Tested with both OpenAI and Zhipu AI providers. The result is the same.

Confirmed that I am not in a Conda environment.

Used nvm to switch from Node.js v22 to the stable LTS version v20.

Resolved potential .npmrc conflicts using nvm use --delete-prefix.

Given that the issue persists across different Node.js versions, providers, and after a complete re-installation outside of any Conda environment, this appears to be a bug related to the application's core initialization on an Apple Silicon (ARM64) macOS environment.

Thank you for your reply. I tried running the command you suggested, and here is the output I got:

i had this exact same issue. I figured that i had to add the provider and the model name to the model definition.

So i had to add sth. like:
lmstudio/gpt-os-120b or
lmstudio/qwen/qwen3-coder-30b-8bit

to make it work with my lmstudio setup.

That fixed it for me since then my local models are working like a charm (most of the time :-))

@manao29 looks like some sort of permission issue given how you installed opencode, I assume you installed via npm here?

Thanks for your help! the earlier 400 Bad Request issue is now resolved. It is the permission issuse. It turned out to be caused by :

Permission problems in the ~/.bun and ~/.cache/opencode directories (some files were owned by root). I fixed this by cleaning those directories and resetting the ownership/permissions to my user.

After correcting these, the provider initialized successfully and the 400 error was gone.
