I daily use the free tire of Le Chat and it is perfect for my needs, like creating TLDR summaries of articles.

I use it. It’s solid and I like the company.

In case someone else was interested about the company behind it (went to look where it is from):

We are Mistral AI, a pioneering French artificial intelligence startup founded in April 2023 by three visionary researchers: Arthur Mensch, Guillaume Lample, and Timothée Lacroix.

Edit: sorry OP I didn’t have any prior experience to comment about.
