Has anyone tried Zyphra 1 - 8B MoE?

Zyphra AI released ZAYA1-8B, a Mixture-of-Experts reasoning model with under 1B active parameters trained on AMD hardware. Despite its minimal active parameter footprint, it reportedly challenges DeepSeek-V3.2 and GPT-5-High on math and reasoning benchmarks using test-time compute scaling. Teams running inference-constrained deployments should evaluate this immediately for cost-per-token efficiency gains.
