Mistral, a Paris-based artificial intelligence (AI) company founded in 2023, has released a new AI model called Medium 3.
According to the company’s announcement on May 7, “Mistral Medium 3 delivers frontier performance while being an order of magnitude less expensive”.
Medium 3 joins the company’s lineup of previous releases, including open-source models like Mistral 7B, Mixtral, Codestral, and Pixtral. However, unlike those earlier models, Medium 3 is not open-source, and users cannot modify or run it on their own devices.

Medium 3 costs $0.40 per million input tokens and $2 per million output tokens. Reviews by Artificial Analysis rated it as one of the best non-reasoning models available. It competes closely with options like Llama 4 Maverick, Gemini 2.0 Flash, and Claude 3.7 Sonnet.
Sophia Yang, a representative from the company, stated:
Mistral Medium 3 shines in the coding domain and delivers much better performance, across the board, than some of its much larger competitors.
Additionally, Medium 3 supports a 128,000-token context window and can process text and images in over 40 languages. This makes it useful for a wide range of tasks, including handling documents and visual content.
Currently, the model is aimed at business use rather than everyday users. It is available through LeChat, Mistral’s chatbot interface, and is designed to work with business systems. Companies can fine-tune it, connect it with internal data, and keep improving it with continuous updates.
Meanwhile, on April 28, OpenAI introduced new features to its AI chatbot, ChatGPT. What are they? Read the full story.
