MobileWan, Qualcomm Runs a 5B-Parameter Video Diffusion Model on a Phone — Qualcomm AI Research introduces MobileWan, which the authors call the first 5B-parameter video diffusion model that runs on a commercial phone. Instead of shrinking the model, they shrink its runtime footprint from the server-scale Wan2.2-5B using recurrence distillation (so it runs like an RNN with near-constant memory), causal linear attention, per-head pruning, step distillation, and an optimized VAE decoder. The reported result is 5-second 480×832 videos at 16 fps in 20 seconds, scoring 83.79 on VBench, which the authors position as state of the art for mobile. QaulcommAIResearch ↗
My takeaway: It is quite impressive that a video generation model can be run on mobile. It shows on-device inference moves generation cost off the server and enables offline use.
Tools & Open Source
OpenAI x Work Louder "Codex Micro," a Physical Keypad Built for Managing AI Agents — OpenAI's Supply Co. store has partnered with hardware maker Work Louder on the kbd-1.0-codex-micro, a $230 mechanical macropad that OpenAI positions as a control surface for agentic coding work with ChatGPT Codex. OpenAI describes the main feature as a set of "Agent Keys" that use live RGB lighting to show each agent's status pulled from Codex, so you can see what's thinking, running, waiting, or done without switching chats. A joystick triggers common Codex workflows like PR review, debugging, or refactoring. Dedicated command keys map high-frequency actions such as accept, reject, and push-to-talk. A rotary dial adjusts the model's reasoning level on the fly. The device connects over Bluetooth or USB-C, works on Mac and Windows, and ships with a 32-key Codex icon keyset. It's currently listed as out of stock. OpenAI ↗
My takeaway: I like how live agent status is shown in different colours. I believe the functional features imply a human-in-the-loop model, not full autonomy.
