Summary

TLDRMystal AI, a new company started by ex-Meta and DeepMind employees, has released Mystal 7B - an open source language model with 7.3 billion parameters. It outperforms the much larger LAMA model on benchmarks and has faster inference thanks to innovations like grouped Query Attention. The post demonstrates using Mystal 7B locally with AMA and Hugging Face. It highlights the chat version fine-tuned for conversational tasks. Early testing shows promising performance on math problems but some inconsistencies. More testing is needed to fully evaluate capabilities.
