The open source AI community was taken on a rollercoaster ride when a new open source large language model (LLM) called “miqu-1-70b” surfaced on HuggingFace, appearing to rival the top-performing Mistral 8x7b and OpenAI’s GPT-4. The model’s exceptional performance noted by users and experts sparked speculation and curiosity. However, the mystery was unraveled when Mistral’s co-founder revealed that the leaked model was a retrained version of an old model, making it not entirely new. Despite this, Mistral’s CEO hinted at future advancements, possibly surpassing GPT-4, which could disrupt the dominance of closed source AI models. The potential implications for the competitive landscape and the growing influence of open source AI on enterprise applications are significant.
