MongoDB - Build AI That Scales
Mini toolsZAYA1-8B
By Zyphra AI
ZAYA1-8B is a post-trained reasoning version of Zyphra’s small MoE language model, designed to deliver unusually strong math, coding, and detailed reasoning for its size. The model card says it has 8.4B total parameters with 760M active parameters, is trained end-to-end by Zyphra, and uses architectural plus training innovations to push performance far above similarly sized models. Zyphra positions it as especially effective for long-form reasoning and test-time-compute setups, while also being small enough for local on-device LLM applications.
