Technical questions are unfortunately hit or miss. I'm lately pretty much always using a system prompt that emphasizes short answers [1], and Opus regularly one-shots it while Mistral needs a follow up. I use big-AGI as a model router [2] (dumb name, great software), which makes switching midway very easy though. For coding I'm still using Claude Code mostly out of inertia (although I really want to move to an OSS harness) and the one time I tried their `vibe` tool months ago it was a bit rough.
Mistral TTS with diarization is also great and cheap. That's the only thing for which I use their web UI.
[1] Give a short but helpful answer to the question the user asks. When helping with a computer-related task, unless the user asks, don't give any installation or setup instructions, but just get straight to the point. When the user asks a follow up question, give a more complete and longer answer while still not overexplaining. When the user prefaces the question with "short mode off" in any question, give a full and well considered reply.
The new Mistral Medium 3.5 is also a big improvement over devstral-2
I think its dumb.
Their support is hidden away in a chat bubble at the bottom. But they do respond promptly.
Its decent, but after switching to Google i wouldn't go back
Mistral themselves focus more on b2b; financial services, manufacturing, stuff like that, and they get some big clients that way.
Despite not being their target, I started using them because they have many open models. I continue using them because, yeah EU, but also because the community is great and the tool makes me think more than Claude does. Last, I stick with them because they are one of the few AI companies that are up-front about their environmental impact and are actually trying to minimize it while still providing a decent product.
If you can express a solution in Lean you can formally prove or disprove it. Formal verification is making a debut in traditional engineering toolkits.
LLMs are a near-afterthought at this point if you don’t have data residency requirements. I love them and they’re slightly underrated, their models are consistently well-trained, open, but as you note, behind. There is no metric that will say they’re ahead in anything.
I’ve also found it very good at pulling info from pdfs. Even a complicated festival with multiple venues and timetables.
But I admit I only consider them because they're from France. Haven't seen a dimension where they're competitive for general users
I am. I use them primarily through their vibe CLI.
Reason is simple: They are cheaper (by almost one order of magnitude compared to Claude) and still do the job pretty well.
For small programming tasks, quick prototyping, refactoring or anything verbose and not requiring a context too large: I first go to Mistral and then eventually to Claude if I'm unsatisfied.
I also found out some of their models to be more responsive than OpenAI ones (which is not so surprising considering the size).
My tasks are mainly C++ and Python programming. People in other languages might not share my enthusiasm.
Nope. This is not my experience.
Public pricing in token/$ is only part of the equation.
Mistral tooling to consume significantly less tokens-per-given-task than the Anthropic ones.
My bills currently reflects that.
We complain too much about not having enough major competitors in the IT space, to not support a burgeoning one even if it's less powerful than SOTA labs
Are you trying to instruct me like an LLM?
We cannot use open source LLMs on-prem, I asked. So that's basically a hard requirement to use mistral, even though Chinese models are strictly better on every dimension.
However these days I usually have Qwen 3.6 27B already loaded so I mostly just use that instead.
Vibe (the CLI Kiro-like tool) feels more "Claude-ish" as it has more terse answers, while the Le Chat can get quite chatty if you really push it ( * ). Prompting it right gets Le Chat more focused and back to being terse.
( * ) Le Chat is by default in "Fast" mode. It also has "Think" and "Research", but I've not felt the need to use those yet.
As a practical example:
I'm doing some on-and-off family research when I can and have some time since it's the rabbit-holest of all rabbit-holes.
I already knew the answers, but decided to test how well Le Chat does. I fed a 208 year old church book page to Le Chat and asked if it can read that handwritten old cursive Swedish and tell me the contents. Le Chat had a look and then explained it could not, but it pointed me to something I had completely missed before, despite having looked for it: The Swedish Lion OCR model by Riksarkivet (Swedish National Archives) which is purpose-built for OCRing such records (the tool by READ-COOP including The Swedish Lion is at http://www.transkribus.org/).
Then, Transkribus confirmed my existing information and confirmed that I can kind of sort of read that cursive too. I did not expect any new findings here, just to verify against known facts and things were OK. The tip to Transkribus was very nice and I'll be using that tool more.
After this, I asked if Le Chat could dig up some more information about the person (it's a Swedish-Russian noble family connection so a lot of written material exists). Le Chat went about it, summarized real web pages, and the information matched with what I knew already, which was good, no hallucinations or such. I prompted Le Chat further towards the parents and grandparents and so on, it kept on replying with factual summaries and references to web pages that actually exist.
This was all in all very good. For what I earlier spent perhaps a weekend or two (taking like two weeks of wall clock time) in total, I could dig up basically the same information, with sources referenced, in a fraction of the time. Even if Le Chat could not read the page, it pointed to Transkribus and that was very helpful.
The point is: Mistral performs well for me and I see no reason to use something else. There's also the option to turn off the "use my inputs to learn the model". I don't know if Claude has it or not.
Edit: formatting Edit: READ-COOP SCE does the Transkribus
