New course on serving LLMs efficiently -- how do you serve models to many concurrent users at low latency and reasonable cost? This short course is built with @RedHat and taught by @cedricclyburn.
Efficient LLM serving requires efficient memory management. A 70B-parameter model takes ~140 GB just to load the weights. On top of that, every active request needs its own chunk of GPU memory, the KV cache, to store the token context it has built up so far. In this course, you'll learn to reduce a model's memory footprint with quantization and serve it using vLLM, which handles many concurrent requests efficiently through smart memory management.
Skills you'll gain:
- Quantize a model and measure the accuracy tradeoff
- Serve a model with vLLM and watch it handle concurrent requests efficiently
- Benchmark your deployment and make informed tradeoffs between speed, cost, and accuracy

中文摘要
Andrew Ng 宣布与 Red Hat 合作推出 LLM 高效服务课程，主讲人 Cedric Clyburn。核心知识点：
1. 内存是瓶颈：70B 模型仅权重就约 140GB，每个活跃请求还需要独立的 KV cache 存储上下文。 2. 量化 压缩模型内存占用，并衡量精度损失。 3. vLLM 通过智能内存管理高效处理大量并发请求。 4. 基准测试：在速度、成本、精度之间做取舍。
