#gpu + #mac

TL;DR: Niklas and I built a fully OpenGL ES 3.0 compliant GPU driver for the M4 Mac Mini and MacBook Neo in about a month, a process which normally takes years. Here is Chrome and Firefox running WebGL on the M4 Mac Mini with working compositing:

Ninety-nine percent of the time a simple /goal resume or “keep going” was enough to have the LLM continue (which also shows the restrictions were overly aggressive), but they still broke my unattended workflow. I coded the fastest, dumbest possible solution: a daemon that takes a screenshot every minute, diffs it against the last screenshot, and if identical (because Codex stopped making progress) types /goal resume. I accidentally left it on in some group chats

Take note that the smaller AI models run consistently and smoothly without using the full resources, but the DeepSeek R1 model with 671 billion parameters requires Apple's highest configuration of the M3 Ultra chip - a whopping 512GB. However, macOS imposes a limitation on VRAM allocation by default, and Dave Lee had to increase the limit manually through the Terminal, bumping it up to 448GB.
