 * The anthropic models available in the plugin is no longer available in the Anthropic
   API, resulting in a 404 request.
 * These should be updated to Claude Haiku 4.5 and Claude Sonnet 4.6.
   To prevent
   future issues with this, anthropic supplies an API enpoint to list all current
   models:
 * [https://api.anthropic.com/v1/models](https://api.anthropic.com/v1/models)
 * You should implement a dynamic read of this API enpoint to make sure the selected
   model is available.

 * Hi, thanks for the heads-up!
   I’ve updated the available models using that endpoint.
   The change is available from release 2.8.1.Thanks!
