    - LLM training optimizations (e.g., FlashAttention-style techniques)  
    - LLM inference: continuous batching, paged attention, disaggregated prefill/decoding  
-   - Scaling laws, test-time compute and reasoning, and “LLM + X” applications (RAG, search, multimodality, tool use, agents, etc.)

 (Guest lectures cover topics such as ML compilers, LLM pretraining and open science, fast inference, and tool use and agents, serving as complementary extensions.)
