Mistral represents the new trend in the field of large models this year, launching closed-source models to challenge OpenAI. Its business model is similar to OpenAI's, offering paid services through APIs. Mistral, representing European large model enterprises, has influenced the legislative process of the Artificial Intelligence Act. Mistral's pricing is close to OpenAI's, but its distinctiveness is unclear. Its native function calls and JSON mode have been praised. It has been compared with models like Llama2 and Gemini Pro 1.0. Mistral has released a smaller version of its closed-source model, Small, and introduced the Le Chat chat assistant, with plans to launch a paid version. The team consists of former employees from Google Deepmind and Meta.
