The September 2026 agentic family from Nex-AGI, an innovation alliance initiated by the Shanghai Innovation Institute. Three sizes, all post-trains of other labs' base weights: mini and Pro continue the multimodal Qwen3.5 lineage of Nex-N2, while Max is the alliance's first trillion-scale post-train, built on a 1.6T text-only DeepSeek-V4-Pro base. Vision is treated as an action interface rather than an input mode — the models drive computers and browsers and check their own work from what appears on screen. Max takes BrowseComp at 92.6, ahead of every model in Nex's own comparison table. Only the 35B mini is realistically self-hostable.

The cheapest GPU that runs Nex-N2.5 locally (min 22 GB VRAM) is the AMD Radeon RX 7900 XTX (24 GB).

Minimum VRAM: 22 GB. For best results use Q4_K_M quantization.
Nex-N2.5 needs about 22 GB VRAM at Q4_K_M quantization for its smallest variant. Variants: Nex-N2.5 mini (22 GB, Q4_K_M); Nex-N2.5 Pro (240 GB, Q4_K_M); Nex-N2.5 Max (967 GB, Q4_K_M). On Apple Silicon, unified memory counts toward this requirement.
Yes — Nex-N2.5 runs on an RTX 4090 (24 GB) and other 24 GB cards such as the RTX 3090. Smaller variants also fit comfortably on 8–16 GB GPUs at Q4_K_M.
Q4_K_M is the best balance of quality and VRAM for Nex-N2.5 in most cases. Choose Q8_0 for near-lossless quality if you have spare VRAM, or smaller quants (Q3/Q2) only when memory is tight.
Install Ollama, then run: ollama run . This downloads Nex-N2.5 and starts a local, OpenAI-compatible endpoint — no internet connection is needed after the initial download.
