Cerebras Delivers Breakneck LLM Speed, Yet Nvidia's CUDA Gravity Dominates

NVIDIA just reported a blockbuster data-center quarter powered by CUDA, building a massive software moat, while Cerebras touts wafer-scale speed but braces for negative margins and heavy, CUDA‑centric integration that requires specialized compilation and custom engineering. Despite a $20B+ OpenAI inference deal and benchmarks showing ~21x latency advantage, the lack of broad framework support outside CUDA and the threat of OpenAI’s Jalapeño chip suggest Nvidia’s platform advantage remains hard to dethrone in the near term.
