What is Mistral AI?
This is a French company specializing in artificial intelligence. It was founded in 2023 by CEO Arthur Mensch. The company’s French roots are reflected in its name: mistral refers to the wind of the same name in the Rhône Valley. Its human resources policy reflects a strong vision: it employs 200 people, from 15 different nationalities, and 50% of team leaders are women. Mistral AI is based in the heart of Paris.
This French start-up specializes in frontier AI, which is a collective term for the most advanced AI applications currently technologically possible. Le Chat is one of those.
What is Le Chat?
This is Mistral AI’s chatbot and it is quite similar to ChatGPT. The name is a French pun: “chat” in French means not only “chat,” but also “cat.” A wink that you see reflected in the footer (the bottom part) of Mistral AI’s website: a pixelated cat waving its tail.
Launched in February 2025, Le Chat excels in speed. In fact, with the Flash Answers feature, the chatbot can answer up to 1,000 words per second – outpacing ChatGPT, which produces 650 words per second. Flash Answers are concise responses to simple questions ,such as “What is the capital of the Netherlands?” Le Chat automatically uses this feature for quick replies.
What can Le Chat do?
Le Chat can basically do everything you are used to from other AI assistants:
- Generate text and conduct conversations in several languages, including Dutch
- Extract information from its own database and search the web
- Creating high-quality images
- Generate code and provide technology support for software and hardware
- Analyzing images
- Performing calculations
- Interpreting and generating documents
- And so on
So sustainable entrepreneurs can also get started with Le Chat. How about these examples?
- A brainstorm on innovations for sustainable products, materials or services: you get quick inspiration and don’t depend on Big Tech.
- Searching for and understanding grants for sustainable projects: Le Chat can search the Internet and suggest the interesting grants for your project.
- Interpreting sustainability data, calculating your carbon emissions and making suggestions on how to reduce them.
How does Le Chat work?
Go to chat.mistral.ai. Do you just want to try? Then you can have limited chat without an account. Want to be able to find your old chats later? Then create an account.
The free version already gets you very far. Do you need Le Chat for large projects? Or do you want to use it intensively on a daily basis? Then consider a professional subscription.
Is Le Chat really a sustainable chatbot?
Unlike other larger players like OpenAI (ChatGPT), Mistral AI is transparent about its emissions. For example, they have calculated that generating an A4 sheet of text is equivalent to:
- 1.14 g CO2 emissions, or streaming a video for 10 seconds
- 0.05 l water consumption, which is what one radish needs to grow
- 0.2 mg of antimony, a chemical element needed to make a 2-cent coin
Mistral AI is aware that the location of a data center is the most important factor in keeping its carbon footprint as low as possible. For example, data centers for Mistral AI near Paris and in Sweden being built. The new Swedish data center will use 100% renewable energy.
It also seeks to use models that target specific applications when training models. This would also help reduce the footprint.
Furthermore, the company behind Le Chat urges its users to think about the environment while using it. This can be done in the following ways:
- Focused prompting so you get the desired results faster
- Ask for short, grouped answers
Le Chat isn’t 100% sustainable yet, but you can be sure the company prioritizes sustainability.

Is Le Chat a good privacy-friendly European alternative?
Mistral AI is a French company and thus must comply with the European security directive GDPR. In fact, according to a study from 2025, Le Chat is the most privacy-friendly AI assistant of the 11 largest chatbots. In this, Le Chat excels:
- The company is very transparent about data collection
- It is easy for users to opt out of using personal data to train models
Le Chat would even share only the prompts used with its own company, Mistral AI. So when it comes to privacy, you’re definitely in the right place here.
For developers: want to build your own chatbots for businesses and organizations? Mistral AI offers the other language models as open source (source code available to everyone). With this, you have full control over your privacy and are not dependent on a company’s cloud.
How European is Le Chat?
Mistral AI is on paper and in practice a French and therefore European company. In recent years, this company received a lot of investment from the United States of America. But at the time of writing (February 2026), it is the Dutch chip company ASML the main shareholder of Mistral AI.
Which is better: Le Chat or ChatGPT?
On several fronts, Le Chat is the clear winner:
- At 1000 words per second, Le Chat is about 40% faster than ChatGPT (650 words per second)
- Le Chat gives short and concise answers, it writes less lengthy speeches than ChatGPT
- The images are of considerably better quality than those of ChatGPT

How do I use Le Chat?
In January 2026, I switched from ChatGPT to Le Chat. And to get straight to the point: I don’t want to go back. I am particularly charmed by the quick response time, the short and concise answers and the good knowledge of Dutch and French of this AI tool. Ideal for me as an entrepreneur in bilingual Brussels.
Le Chat, meanwhile, helps me with a lot of things, like this one:
- Reviewing French emails for spelling and grammar: French is my third language, so an artificial editor definitely comes in handy
- Generating ideas for photography projects: mainly in the form of text, as I prefer not to generate images because of CO2 emissions
- Interpreting web statistics
- Checking whether articles and web pages are easily findable in search engines and AI tools
For the rest, I try to keep the use of AI to a minimum because I am aware of the large ecological footprint. For example, I look something up in Ecosia first and if I really don’t find it, I go to Le Chat.
