Nex-AGI

Released: -
Data date: October 3, 2026

Nex-N2.5-Max marks Nex-AGI’s first complete post-training effort at trillion-parameter scale, according to the company. Its foundation is a text-only MoE model with 1.6 trillion parameters. Unlike Mini and Pro, Max does not accept visual input.

Nex-AGI publishes the weights under Apache 2.0. The release does not list a dedicated hosted Max endpoint.
