About
Nex-N2.5 is Nex AGI's next-generation open-weight agentic model family for long-horizon tasks in real-world environments. The family ships mini and Pro multimodal MoE variants with stronger computer-use and visually grounded agent workflows, plus Max — a 1.6T-parameter text-only MoE foundation model with a 1M-token context window. Distinct from the earlier Nex-N2 family; Pro is not seeded in this pass.
