I am Alex (Wei) Chen 陈伟, a Director at Qualcomm. Before joining Qualcomm through its acquisition of Nexa AI, I founded Nexa and served as its Founder, CEO, and Chief Scientist, with the goal of making generative AI more efficient and accessible on everyday hardware.

At Nexa, our team built the NexaSDK — an open-source toolkit for running AI models on edge devices that found a real home in the developer community. I was the main technical author behind much of this work, including the Octopus model series, OmniVLM, OmniAudio, and NexaQuant. Along the way, we worked closely with engineering teams at NVIDIA, AMD, Microsoft, Google, IBM, and Intel, and deployed with enterprise partners like Geely, HP, Lenovo, and İşbank.

My interests sit at the intersection of AI systems, LLM/VLM inference, hardware-software co-design, and robotics. I’m especially drawn to the question of how we build intelligence that can act in the physical world. I hold a PhD from Stanford University (2024) and a Bachelor’s from Tongji University (2019).

Selected Work

NexaSDK

Runtime

A GenAI inference runtime that runs models on NPU — 8,000+ GitHub stars and #1 on GitHub Trending.

Hyperlink

Application

A local AI agent that lives inside your computer — it searches across all your files, fully private. 2.1M views and 30K users in two months, featured by NVIDIA, Microsoft, Qualcomm, and AMD.

Octopus

Model

The world's first AI agent model built to run directly on hardware — function calling across PCs, phones, wearables, automotive, and robots — part of a model line that trended top-3 on Hugging Face, featured by Google I/O and the Google DeepMind blog.

Recognition

Silicon
Qualcomm

Shipped our work across Snapdragon for Android, the Hexagon NPU, Granite 4.0 at the edge, and IoT & robotics — and featured us seven times in “This Week in AI.”

NVIDIA

Co-launched our local AI agent on RTX, featured us at their CES 2026 booth as a highlighted startup, and published a 1.3M-view feature on YouTube.

AMD

Made us a partner for CES 2026, and published our work on image generation on its NPU and DeepSeek R1 speedups.

Intel

Featured us on its developer channel.

Models
Google DeepMind

Featured OmniAudio in the Gemmaverse and our work at Google I/O 2024.

IBM

Named NexaML a supported framework for Granite 4.0, alongside vLLM, llama.cpp, and MLX.

Alibaba / Qwen

Highlighted our day-0 Qwen3-VL support and Qwen3 on Qualcomm NPU.

Liquid AI

Partnered with us on the LFM2.5 launch and LFM2.5 Thinking.

Hugging Face

Thomas Wolf ranked our models among the most-downloaded, and CEO Clément Delangue put out a public collaboration call.

OpenAI

Featured our work via Developer Relations.

Platforms
Microsoft

Put us on stage at Ignite 2025 keynote as an official partner.

Talks & Appearances

This blog is where I think out loud about AI, robotics, and the systems behind them. If something sparks a question or a conversation, I’d genuinely love to hear from you.
