Live from New York, it's...$CBRS @Nasdaq thank you for the welcome!


We raised $56M to help build the next era of interactive entertainment. Series B led by @sequoia, Series A led by Sea. Astrocade lets anyone create games with AI, play them with friends, and share them with millions. But this isn’t about replacing creativity. It’s about giving more people the tool to bring their taste, humor, stories, and craft to life. Today, the fun goes public.

Excited to share Vibes — a new feed in the Meta AI app for short-form, AI-generated videos.

🧮 Calling all Mathletes, this one is for you. We’ve been asked to show the math behind our MoE claims. So we did. Our analysis confirms: On GPUs, expert parallelism creates severe communication overheads that dwarf computation and make MoE training painfully slow. At Cerebras, we avoid model parallelism entirely, but sparsity subdivides batches and leaves experts I/O bound. With BTA, we fix it. By decoupling batch size requirements across experts and attention layers, we remove the bottleneck. @dmsobol breaks it down.
