Mistral: Mixtral 8x7B Instruct
Analysis Summary
Mixtral 8x7B Instruct was an influential open-weight model at its 2023 release, demonstrating the viability of sparse mixture-of-experts architectures. Today, its intelligence index of 2.4 and limited coding benchmarks place it well below current mid-tier models. The 32K context window is constraining, and while tool use and function calling are supported, its agentic reliability is limited.
For businesses, Mixtral 8x7B Instruct has largely been superseded. Its reasoning and coding capability are insufficient for most professional workflows, and its pricing at $0.54 per million tokens for both input and output is not competitive given the availability of far more capable models at similar or lower cost. It remains of historical interest as an open-weight model but offers little practical advantage today.
Teams that originally adopted it for its open-weight flexibility should consider migrating to more recent open-weight alternatives, which offer substantially better reasoning, larger context windows, and stronger instruction following at comparable deployment costs.

Editorial notes
Mixtral 8x7B Instruct is a legacy open-weight MoE model from Mistral with limited reasoning benchmarks, a small context window, and pricing that no longer reflects its capability relative to current alternatives.
Rankings consider pricing, capabilities, benchmarks, and real-world applicability and are refreshed as new models launch. Feedback?
