[Bug] Could not restore model anthropic/claude-opus-5. Using prime-inference/z-ai/glm-5.2

Affected area

Coding agent and CLI

What happened?

This is happening more and more to me, and it's hard to pin down the exact path through it.

The latest one was a long-running research task, which ended overnight. When I come in this morning it's in this state. If I try and select the model via /model I just get Error: Model not found: anthropic/claude-opus-5.

Quitting and starting again allows a new session to pick up the right model, but existing sessions can never get the model back.

Steps to reproduce

1. Run prime-agent, connect to an external model, not a z.ai model. For this task I used anthropic with ANTHROPIC_API_KEY set.
2. Start a long-running research task.
3. Walk away until complete. Allow the system to idle and lock the screen.
4. Observe the error Could not restore model anthropic/claude-opus-5. Using prime-inference/z-ai/glm-5.2
5. Using /model to switch back no longer works and prints Error: Model not found:...

Expected behavior

I expect it to always be able to connect to the right model.

Prime Agent version

0.8.0

Environment

macOS 26.5.2, Terminal.app

Additional context

This started yesterday (2026-08-24). Up until then I had used prime-agent for a while (since the Open Source release) without it happening, so it made me wonder if it's a server-side bug.

Note: This has not happened again since that single day of it happening a lot. I still suspect something server-side.
