Nex-N2.5: Shanghai Innovation Institute open-sources agent-recipe models

nex-agi, the agent alliance of the Shanghai Innovation Institute (nex.sii.edu.cn), open-sourced the Nex-N2.5 family: N2.5-Max (created Sep 7), then N2.5-Mini (a 35B multimodal agent model) and N2.5-Pro (created 2026-09-08T11:01Z) under Apache-2.0. The Pro repo uses the qwen3_5_moe architecture tag (image-text-to-text) — the family is built on Qwen MoE bases with the alliance's agent post-training. N2.5-Mini is free to use on OpenRouter; the family sat at #5-7 of HF trending at capture.

A new kind of participant has joined the open agentic-model wave: a state-backed alliance publishing agent recipes on top of Qwen bases rather than frontier weights. For trend tracking this broadens the multi-org base; for engineers the value is the agent post-training recipe on an already-familiar serving surface.
