Mixtral 8x22B Instruct v0.1 — Hardware Requirements & GPU Compatibility

Chat

Mixtral-8x22B-Instruct-v0.1 is Mistral AI's instruction-tuned chat model, fine-tuned from the Mixtral-8x22B-v0.1 base model. It is a sparse Mixture-of-Experts model with 8 experts per layer and 2 active per token, giving roughly 39.2 billion active parameters out of about 140.6 billion total, and supports function calling for agentic and tool-use workflows. Because all experts must stay in memory even though only two run per token, it needs a multi-GPU workstation or a high-memory machine even once quantized. Context length is 65,536 tokens. It is released under the Apache 2.0 license, permitting unrestricted commercial and research use. It was published in April 2024, as the instruct variant of the larger successor to Mixtral 8x7B.

Frequently Asked Questions

How much VRAM does Mixtral 8x22B Instruct v0.1 need?

Mixtral 8x22B Instruct v0.1 requires 85.2 GB of VRAM at Q4_K_M, or 282.0 GB at BF16. Full 66K context adds up to 14.6 GB (99.7 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 140.6B × 4.8 bits ÷ 8 = 84.4 GB

KV Cache + Overhead ≈ 0.8 GB (at 2K context + ~0.3 GB framework)

KV Cache + Overhead ≈ 15.3 GB (at full 66K context)
