Mixtral of Experts

Source: Dev.to

Overview

Mixtral 8x7B is a language model that distributes tasks across many tiny specialists, achieving both speed and intelligence. It employs a Sparse Mixture of Experts architecture where each layer contains eight feed‑forward blocks, and a router selects two experts for every token. The selected pair can change at each step.

Architecture

• Sparse Mixture of Experts: Each token can access up to 47 B parameters in total, while only about 13 B active parameters are used during inference, reducing computational cost.
• Routing: A small router dynamically picks two experts per token, allowing the model to adapt its computation on the fly.

Training and Performance

• Trained for very long contexts, handling up to 32 k tokens.
• Matches or outperforms much larger models on benchmarks, especially in math, coding, and multilingual tasks.
• An instruction‑tuned version surpasses several popular chat models in human evaluations.

Both the base and instruction‑tuned versions are released under the Apache 2.0 license, enabling the community to experiment with them.
