⚡ Meet NexRT, the low-latency decode engine behind Nex-N2.5.
💡 Built for single-request inference on Nex-N2.5-Pro.
• 1,000+ tokens/s at 8K context on 8×H100 with DFlash*
• Standard decoding, MTP and DFlash
• Context parallelism for long contexts, up to 256K
SGLang handles prefill; NexRT handles decode. The two engines share routed MoE weights.
Custom CUDA kernels, full decode CUDA Graphs and direct GPU communication help reduce latency throughout the decode path.
Performance report and demo now available. Source code will follow.
*DFlash throughput assumes an average of 5.5 committed tokens per round; actual throughput depends on draft acceptance.

🚀 Free API access for Nex-N2.5-Pro and Nex-N2.5-mini is now live on ModelScope! Give it a try!
🔹 Nex-N2.5-Pro: modelscope.ai/models/nex-agi…
🔹 Nex-N2.5-mini: modelscope.ai/models/nex-agi…
⏰ Free trial runs until September 24 (Beijing Time).
Built for long-horizon agentic tasks, the Nex-N2.5 family excels at computer use, web browsing, and visually grounded workflows.
An agent model, plus two multimodal models that can see and operate computers. Nex-AGI releases Nex-N2.5 in mini, Pro, and Max sizes.📜 Apache 2.0.

🏆 Max leads the published BrowseComp comparison with 92.6. Pro ranks first on OSWorld-G with 87.4.
🖥️ The 35B mini and 397B Pro browse the web, operate software, verify results, and self-correct through visual feedback.
🧠 The 1.6T Max targets complex text-based agent tasks, from coding and tool use to research and knowledge work. It marks Nex-AGI’s first full post-training run at trillion-parameter scale.
⚙️ All three support function calling and direct, adaptive, or full thinking modes.

What happens when an AI stops telling you how to build something and actually builds it?
Nex-N2.5 Pro took an idea from concept to playable game:
→ Rough concept
→ 2D design
→ Blender 3D environment
→ Working game
The interesting part wasn’t the final result.
It was the process.
The model interacted directly with the tools, observed the changes on screen, made adjustments, and continued working instead of simply generating instructions.
That’s the real computer-use test.
Can an AI:
• Open Blender and build a scene?
• Inspect the output and iterate?
• Write a script, tweak parameters, and troubleshoot?
• Hit a limitation, switch to the GUI, and finish the task?
Nex-N2.5 Pro is starting to make that workflow feel surprisingly real.
You can try it on OpenRouter for a limited time:

Nex AGI's agentic N2.5 family is live on OpenRouter: Nex-N2.5-Pro and Nex-N2.5-Mini.
Both are built to turn goals into working, verified outcomes, with agentic coding as the core strength. Tool calling and adjustable reasoning effort on both.

💥 CAD Agent 又往前走了一步！Nex-N2.5 Pro 从零建模机械臂，最后直接交付 SolidWorks 工程文件。
整个流程不是生成一张 3D 效果图，而是全程调用 CAD 工具完成设计，你可以看着它一步一步操作你的电脑：
✅ 拆分底座、关节、连杆和夹爪
✅ 生成并执行 CAD 自动化脚本
✅ 遇到 BLOCKER 后修改方案继续跑
✅ 完成零件建模、整体装配和爆炸视图
✅ 输出 robot_arm.SLDASM、运行记录与验证结果
从一句需求，到一套可以打开、拆解和继续修改的 CAD 项目。
这个完成度确实有点夸张了 🤖
这将使得未来机械设计变得更加高效，快速
另外最重要的是Nex-N2.5 Pro 正在 OpenRouter 限时免费开放：

i love GPT-6 Astra, so when i heard we were releasing an agentic computer-use model, i got VERY excited.
i kept asking the team: can Nex-N2.5 Pro do that thing like GPT-6 launch video? go from a 2D design into 3D modeling in Blender?
turns out, yes 😭
and then it went a step further and made an interactive HTML game!!
i keep thinking about what comes after this. steam power helped make railways possible. short-form video brought us TikTok, so now we scroll infinitely and shop in the same app.
really wonder what comes next when AI can actually use the tools we use and do it 10x better than me? 😂
Meet Nex-N2.5 family, our latest open source agentic models.
Mini (35B) and Pro (397B) bring multimodal understanding and computer use. Max (1.6T) is a text-only MoE model built for complex reasoning, coding, and agent workflows.
Strong benchmark results in workflow automation and computer use:
⚡ Max scores 50.2 on AutomationBench v1.0.6—just 0.1 points behind Claude Opus 5
⚡ Pro scores 56.4 on OSWorld-2, ahead of Qwen3.8-Max at 46.7
With continuous action, visual feedback, and self-correction, NEX-N2.5 can work across Blender and CAD tools, handle expense reimbursements, and even play PC games—turning visual understanding into sustained, real-world execution.

◆ Complex Front End with HTML gameplay
NEX-N2.5 creates the visual style, builds the animated pelican cycling scene, and adds interactive controls, including adjustable riding speed and light/dark themes.
It combines visual understanding, front-end generation, animation, and interaction design in one workflow.
