Mistral AI, a French startup, is emerging as a formidable competitor in the artificial intelligence sector, closely rivaling OpenAI's ChatGPT 4 with its new open-source model, Mistral LARGE. This model has demonstrated superior performance over all other large language models (LLMs) except for GPT-4 across several benchmarks, including reasoning and knowledge, multi-lingual capacities, and math & coding skills. Microsoft's significant investment of billions in Mistral AI underscores its potential, with the company being hailed as a multilingual maestro nearly matching ChatGPT 4's capabilities. Additionally, the integration of Mistral Large into Merlin's AI capabilities suggests it's not just an advancement in size but also in intelligence, accuracy, and insight, marking it as a potential game-changer in the industry. The live coding test further illustrated Mistral LARGE's advanced capabilities.
