Fast LLM Inference with Cerebras
by DeepLearning.AI
Learn why LLM inference is slow and how ultra-fast serving reshapes what real-time AI apps can do.
Overview
Fast LLM Inference with Cerebras is a free-to-audit, ~1h42m intermediate short course from DeepLearning.AI in partnership with Cerebras (instructors Zhenwei Gao, Sebastian Duerr, and Sarah Chieng). It teaches AI engineers why LLM inference is often slow — much of the time is spent moving model weights from memory to the compute units — and contrasts GPU, TPU, and Cerebras Wafer-Scale Engine (WSE-3) approaches, including keeping weights on-chip. Through 10 video lessons, 4 code examples, and a graded assignment, learners build latency-sensitive applications such as real-time page personalization that adapts as users interact and multi-tool workflows that perform live market-signal analysis in a single fast response, and see how eliminating loading spinners and token-by-token streaming can shift product UX. It also covers multi-agent coding patterns that validate between steps for more robust output.
