Mistral AI’s Available Models
One major thing that sets Mistral AI apart is their strong commitment to open-source technology and empowering the AI community.
Which makes sense, considering their early models were built off Meta’s LLaMA framework. 😄
Mistral has released several powerful open models under the Apache 2.0 license — meaning you’re free to use, modify, and distribute them however you like.
Here’s a quick overview of their key open-source models:
- Mistral 7B: A 7.3 billion parameter transformer model. Despite its size, it outperforms larger models like LLaMA 2 13B. It uses Grouped-Query Attention (GQA) for better efficiency.
- Mixtral 8x7B: A Sparse Mixture-of-Experts (SMoE) model with 45 billion total parameters but only activates 12.9 billion at a time. It performs extremely well across multiple languages (English, French, Italian, German, Spanish) and coding tasks. Mixtral 8x7B even outpaces LLaMA 70B and GPT-3.5 on many benchmarks.
- Mixtral 8x22B: Currently Mistral AI’s highest-performing open model. This SMoE model has 141 billion total parameters but activates just 39 billion during use, offering strong multilingual and coding abilities similar to Mixtral 8x7B.
- Codestral 22B: A lightweight model fine-tuned for coding tasks. It supports over 80 programming languages and offers highly efficient code generation compared to much larger models.
Because these models are open, many third-party groups have taken them and created their own fine-tuned versions — some pretty wild ones too. For example, Dolphin 2.5 is known for being an “uncensored” chat model with basically no filters.
Just a heads up though — if you want to try those versions (like on Hugging Face), it’s completely at your own risk. Don’t say I didn’t warn you! 😆
Mistral AI’s Commercial Model Lineup
Beyond its open-source releases, Mistral AI also offers a suite of optimized commercial models tailored for high performance. These models are accessible through an API and via major cloud platforms like Microsoft Azure.
Here’s a quick overview of their main commercial offerings:
- Mistral Large: The flagship model from Mistral AI, delivering performance that closely rivals GPT-4 across a range of benchmarks. It excels in complex reasoning tasks, supports multiple languages, and handles coding-related activities with impressive skill.
- Mistral Small: Designed for workloads where low latency and cost efficiency are key, Mistral Small maintains strong multilingual capabilities and coding proficiency similar to its larger counterpart.
- Mistral Embed: A specialized model that transforms text into high-dimensional vector representations, enabling advanced semantic analysis for various natural language processing tasks.
These models provide businesses and developers with cutting-edge AI capabilities, combining convenience and scalability through API-based services. Thanks to partnerships with major cloud providers like Microsoft Azure, Mistral AI is expanding the reach and accessibility of its technology.
If you’re curious to try them out, you can visit their API page — they even offer free credits for new users. As for usage statistics or revenue figures, those haven’t been publicly disclosed yet.

How to Write Better Prompts for Le Chat
Prompting Le Chat Mistral effectively follows a few core principles—being clear, providing context, and breaking tasks into smaller steps when necessary. Here are some tips to help you craft better prompts:
- Be clear and specific: Give detailed instructions or ask direct questions. The clearer you are, the more focused and relevant the response will be.
- Provide context: If your query involves a specific topic or scenario, share some background information. This helps the model understand the situation and respond more appropriately.
- Break down complex tasks: For multi-step requests, consider splitting them into smaller, manageable parts. This improves accuracy. (If you prefer not to, you might want to try Claude 3, which handles complex prompts without needing much breakdown.)
- Experiment with wording: If a response isn’t quite what you wanted, rephrase your prompt. Sometimes even a slight adjustment can lead to better results.
- Use supported languages: Le Chat Mistral works best with English, French, Spanish, German, and Italian. Feel free to use any of these languages for a more natural conversation.
- Give examples: If you need a specific style or format (e.g., email writing, social media posts, coding), include examples to guide the model.
- Pick the right model: As mentioned above, choosing the most suitable Mistral model for your task ensures you get the best possible response. Unlike ChatGPT, Le Chat does not automatically pick a model for you.
At the end of the day, practice and experimentation are key. The more you interact with Le Chat, the better you’ll understand how to craft prompts that yield great results.
