A YouTube video showing a custom workflow that uses Claude Opus 5.5 to write code for motion graphics and b-roll for existing videos, which the creator describes as polished.

Up from 84,259 to 99,145 views in 16 hours. 1,583 likes and 112 comments. Published about four days ago.

Why it matters: If your team edits video, this is a workflow you can try now - the model writes code that produces graphics timed to your words; the creator says the approach avoids 'AI slop'.

The model writes code, not video: each clip is a small HTML file that the skill renders to video on your machine.

MicroLLM Lab - a site that runs small language models directly in your browser via WebGPU, no server or API calls required.

Up from 92 to 246 points on Hacker News in about 12 hours. 86 comments.

Why it matters: If your use case is lightweight and you want no network round-trip and no API cost, these models run locally in the browser once downloaded; how fast they answer depends on your device (the site claims under 10 ms to the first token). The tradeoff: capability for control and speed.

Sometimes the right model is the one that runs where you are.
