Andrew Feldman on AI-assisted coding productivity gains at Cerebras.
“They've gone from being sort of 10x guys to being 100x guys.”Andrew Feldman · 21 May 2026
Software-based diffusion LLM inference on commodity GPUs is more scalable than specialized AI inference chips from Cerebras and Groq, according to Stefano Ermon.
“Our solution is software based so it's much more scalable we're still running on GPUs. So you can you know get as much capacity as you as you know as you can get GPUs for which is relatively easier compared to specialized AI inference chips.”Stefano Ermon · 26 Mar 2026
