About

ZAYA1-8B is a small mixture-of-experts (MoE) reasoning model from Zyphra with 8.4B total parameters and approximately 760M active parameters per token. Trained entirely on AMD Instinct MI300X hardware (1,024 GPUs), it incorporates three architectural innovations: Compressed Convolutional Attention (CCA), a novel MLP-based expert router, and learned residual scaling. Post-training uses a four-stage reinforcement learning cascade covering reasoning warmup, adaptive curriculum, large-scale math/code RL with test-time compute traces, and behavioral RL for instruction following. On extended compute (Markovian RSA), it approaches or exceeds frontier models such as DeepSeek-V3.2 and GPT-OSS-120B on mathematics benchmarks.

Benchmark scores(4)

Scores are benchmark-specific and are direction-aware: the same numeric gap can mean very different outcomes across suites. Use the leaderboard context and this model's provider route to decide whether the winning margin is meaningful for your workload.
