Introduction
Today, the team is proud to release Mixtral 8x7B, a high-quality sparse mixture of experts model (SMoE) with open weights. Licensed under Apache 2.0. Mixtral outperforms Llama 2 70B on most benchmarks with 6x faster inference. It is the strongest open-weight model with a permissive license and the best model overall regarding cost/performance trade-offs. In particular, it matches or outperforms GPT3.5 on most standard benchmarks.
Benchmarking
FLOPs7.74e+23
Notes: Assuming the model was trained on ~1-10 trillions of tokens (same OOM as the models from the comparison in Figure 1. Llama 2 was trained on 2T tokens) + Mistral Small 3 was trained on 8T of tokens, we can estimate training compute with "speculative" confidence: 6 FLOP / token / parameter * 12.9 * 10^9 active parameters * 10*10^12 tokens [speculatively] = 7.74e+23 FLOP

Parameters
Parameters46700000000
Notes: 46.7B *sparse* params. 12.9B params used on average: "Concretely, Mixtral has 46.7B total parameters but only uses 12.9B parameters per token. It, therefore, processes input and generates output at the same speed and for the same cost as a 12.9B model."
