Mixtral 8x7B: A Sparse Mixture of Experts language model
Summary: Researchers introduce Mixtral 8x7B, a Sparse Mixture of Experts (SMoE) language model with the same architecture as Mistral 7B. Each layer has 8 feedforward blocks (experts), and a router network selects two experts to process the current state and combine outputs. Mixtral outperforms Llama 2 70B and GPT-3.5 on various benchmarks, particularly in mathematics, code generation, and multilingual tasks. A fine-tuned version, Mixtral 8x7B - Instruct, surpasses GPT-3.5 Turbo, Claude-2.1, Gemini Pro, and Llama 2 70B - chat model on human benchmarks.
