ZAYA1-8B

by Zyphra

ZAYA1-8B is a reasoning-focused mixture-of-experts (MoE) language model from Zyphra with 8.4 billion total parameters and only 760 million active parameters per token. It was trained entirely on AMD Instinct MI300X hardware and achieves competitive reasoning performance at a fraction of the compute cost of larger models.

Primary Use Cases

  • Mathematical reasoning
  • Code generation and analysis
  • Puzzle solving
  • Cost-efficient inference at scale
  • On-premise deployment without NVIDIA hardware

✅ Strengths

  • Competitive reasoning performance vs. much larger models
  • Extremely efficient: only 760M active parameters per token
  • Open-source under Apache-2.0 license
  • Demonstrates AMD hardware viability for frontier model training
  • Novel Markovian RSA enables extended reasoning with constant memory footprint

⚠️ Limitations

  • 8.4B total parameters limits absolute capability ceiling vs. frontier models
  • MoE architecture may have higher memory requirements than dense models of similar active size
  • Relatively new model with limited third-party benchmark validation
  • Primarily reasoning-focused; general instruction following may lag larger models
