Segment 28

This sub-session focused on debugging and optimizing the inference pipeline for synthetic data generation. The reasoning capture bug was resolved by bypassing the OpenAI-compatible chat completions API and directly using SGLang's /generate endpoint with raw token IDs, ensuring faithful capture of reasoning content and tool calls. Server throughput was then optimized from ~600 tok/s to ~930-1350 tok/s by tuning KV cache settings (mem_fraction_static=0.88, bf16 KV, hierarchical cache at 48GB/rank). Finally, a --max-tokens-per-dataset cap (10M tokens) was added to control generation time across the 88K-sample dataset pipeline.
