RadixAttention in SGLang: Prefix Caching Documentation
SGLang's RadixAttention uses radix trees for KV cache optimization. How it outperforms vLLM PagedAttention for multi-turn conversations and agent workflows.
The Infinite Board Problem: Pruning State in Long-Running Reasoning Loops
How to manage the shared state size in complex reasoning loops to prevent context window overflow without losing critical history.
Hierarchical KV Caching: Scaling Context Beyond VRAM Limits
As context windows scale to a million tokens, the KV cache becomes too large for GPU memory. The solution is a multi-tiered cache that offloads data to CPU and NVMe without killing latency.
