Mixtral 8x7B Instruct
Mixtral 8x7B Instruct is a 46.7-billion-parameter mixture-of-experts model from Mistral AI, released December 2023, activating roughly 13B parameters per token across 2 of 8 experts. It was among the first open-weights models to reach GPT-3.5-class quality on standard benchmarks, establishing MoE as a viable architecture for cost-efficient hosted inference. The 32K context window is adequate for most retrieval-augmented generation workloads, though tight by current standards. As of mid-2026 it remains broadly hosted — Fireworks, DeepInfra, Groq — but Mixtral 8x22B and Mistral Small 3 have largely displaced it for new deployments on both quality and cost curves.
