I've been trying to use other LLM providers than OpenAI over the past few weeks: Claude, Deepseek, Mistral, local Ollama ...

While Mistral might not have the best LLM performances, their UX is IMO the best, or at least a tie with OpenAI's:

- I never had any UI bug, while these were common with Claude or OpenAI (e.g. a discussion disappearing, LLM crashing mid-answer, long context errors on Claude ...);

- They support most of the features I liked from OpenAI, such as libraries and projects;

- Their app is by far the fastest, thanks to their fast reply feature;

- They allow you to disable web-search.
