Paris-based AI startup Mistral AI is gradually building an alternative to OpenAI and Anthropic as its latest announcement shows. The company is launching a new flagship large language model called Mistral Large. When it comes to reasoning capabilities, it is designed to rival other top-tier models, such as GPT-4 and Claude 2.
In addition to Mistral Large, the startup is also launching its own alternative to ChatGPT with a new service called Le Chat. This chat assistant is currently available in beta. If you’re not familiar with Mistral AI, the company is better known for its capitalization table, as it raised an obscene amount of money in very little time to develop foundational AI models. The company was officially incorporated in May 2023. Just a few weeks after that, Mistral AI raised a $113 million seed round. In December, the company closed a $415 million funding round, with Andreessen Horowitz (a16z) leading the round. Founded by alums from Google’s DeepMind and Meta, Mistral AI originally positioned itself as an AI company with an open source focus. While Mistral AI’s first model was released under an open source license with access to model weights, that’s not the case for its larger models. Mistral AI’s business model looks more and more like OpenAI’s business model as the company offers Mistral Large through a paid API with usage-based pricing. It currently costs $8 per million of input tokens and $24 per million of output tokens to query Mistral Large. In artificial language jargon, tokens represent small chunks of words — for example, the word “TechCrunch” would be split in two tokens, “Tech” and “Crunch,” when processed by an AI model. By default, Mistral AI supports context windows of 32k tokens (generally more than 20,000 words in English). Mistral Large supports English, French, Spanish, German and Italian. As a comparison, GPT-4 Turbo, which has a 128k-token context window, currently costs $10 per million of input tokens and $30 per million of output tokens. So Mistral Large is currently 20% cheaper than GPT-4 Turbo. Things are changing at a rapid pace and AI companies update their pricing regularly. But how does Mistral Large stack up against GPT-4 and Claude 2? As always, it’s very hard to tell. Mistral AI claims that it ranks second after GPT-4 based on several benchmarks. But there could be some benchmark cherry-picking and disparities in real-life usage. We’ll have to dig more to see how it performs in our tests.
