### 1/5 — Unusable

*2025-11-10*

Well, I thought this app would be ideal to connect to my LM Studio server instance to query my local-running models.

Unfortunately, it incessantly force closes in new chat windows, and the setting page. As a result, I cannot set up my “OpenAI Settings” because the entire application exits before I can save my configuration.

Consider vibe-coding a fix for this buggy application.

### 5/5 — need update to gpt-3.5-turbo-16k
