I used pipx and used AnthropicAI's plugin to use Claude. After 2 weeks of perfectly working, suddenly I got the "this model is invalid" error.

PS: I appreciate the work put into llm tho, it's a neat program I used with my Automator scripts to bring LLMs to macOS before Apple Intelligence was announced. I just wish the stability was not a concern.

That's weird. Were you using llm-claude or llm-claude-3?

The plugins seem to need to be reinstalled after every upgrade

I followed along with the blog post, but got unstuck with llm-cmd not working on Mac OS. Looks like this PR would fix it https://github.com/simonw/llm-cmd/pull/12
