Nex-N2-Pro combines 397 billion total parameters with about 17 billion active on top of Qwen 3.5 397B A17B. Adaptive Thinking controls reasoning depth, while Coherent Thinking is meant to keep the derivation consistent across longer workflows. Tool calling and explicit reasoning traces target demanding work chains.

Within the direct pair with Nex-N2-mini, Pro brings more total and active parameters at a higher compute cost. Nex AGI reports substantial gains over Nex-N1.
