Nex AGI model releases

The lightweight multimodal MoE member of Nex AGI's Nex-N2.5 family (Sep 8, 2026). 35B total / 3B active sparse MoE with a 262K context, sharing the Pro model's multimodal agentic stack (computer use, web browsing, visually grounded workflows) at much lower inference cost. Supports vision, reasoning, function calling, and tool use. Apache-2.0 weights on Hugging Face (nex-agi/Nex-N2.5-mini); hosted as a free preview on OpenRouter at launch.

Nex AGI's trillion-scale, text-only MoE agentic model in the Nex-N2.5 family (Sep 8, 2026). 1.6T total / 49B active sparse MoE with a native 1,048,576-token (1M) context. Supports reasoning, function calling, and tool use; no vision or multimodal inputs. Apache-2.0 weights on Hugging Face (nex-agi/Nex-N2.5-Max); no tracked hosted API route at launch.

Nex AGI's flagship multimodal MoE agentic model in the Nex-N2.5 family (Sep 8, 2026). 397B total / 17B active sparse MoE with a 262K context. Builds on Nex-N2 multimodal foundations with stronger computer use, web browsing, and visually grounded agent workflows; supports vision, reasoning, function calling, and tool use. Apache-2.0 weights on Hugging Face (nex-agi/Nex-N2.5-Pro); hosted as a free preview on OpenRouter at launch.

Nex AGI's open-weight agentic flagship, post-trained on Qwen3.5-397B-A17B (397B total / ~17B active MoE) by the Shanghai Innovation Institute-led Nex alliance. Built around an "Agentic Thinking" framework for long-horizon coding, deep research, tool calling, and terminal execution; accepts text and image input and emits text with explicit reasoning traces and function calling. Apache-2.0, ~262K context. Nex reports parity with GPT-5.5 and Claude Opus 4.7 on several agentic and coding evals. A smaller Nex-N2-mini (35B/3B-active) was announced but is not yet open-sourced.
