Introducing Mistral AI

Mistral AI, a French company founded in 2023 by former Meta and Google DeepMind employees, is dedicated to providing both commercial AI products and robust open-source LLMs. Their Mistral 7B model, released in September 2023, significantly impacted the open-source AI community by outperforming leading models at the time. Mistral Large, launched in February 2024, builds upon this success.

Mistral Large: Key Features

Mistral Large is Mistral AI's flagship model, designed for text generation and rivaling the capabilities of GPT-4. Its strengths lie in:

• Advanced Reasoning and Knowledge: It excels in benchmarks like MMLU, HellaSwag, and Arc Challenge, demonstrating superior understanding and reasoning abilities compared to many competitors. See the benchmark comparison below:
