Description

On Windows, I'm unable to use Synthetic models inside Tasks, be it @general task or otherwise.

This does not happen on either of my Linux machines.

I've tested Anthropic Sonnet/Haiku, Copilot GPT-5, Z.AI Coding Plan GLM4.6. This appears to be exclusive to Synthetic.
Maybe because of : in the name, but I have no idea at the moment. I have not begun to try debugging.

OpenCode version

1.0.57

Steps to reproduce

  1. Authenticate with Synthetic.new
  2. Ask to spawn @general task (or any task)
  3. No response inside the task.

First time tried OpenCode on Windows (usually use Linux); but need to make quick demo.
I also copied my opencode config folder, but there's nothing Linux specific in there.

Works with all other providers Image

But does not work with any of the synthetic models

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

  • #2477: [Bug] id field ignored from sst/models.dev model toml files - This issue specifically mentions problems with Synthetic.new provider where model names need an 'hf:' prefix, which could be causing the underlying task execution failures you're experiencing.

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

Stopped reproducing, probably was an issue on provider's end.
