Unified Memory in SGLang: One Arena for Every Token Lifetime
LMSYS · Published · 3 min read

- What happened
- SGLang introduces unified memory that dynamically shares one GPU memory arena across full-attention KV, sliding-window KV, and recurrent state instead of fixed partitions.
- Why it matters
- Matters for engineers serving hybrid models with mixed attention types who currently tune memory ratios at startup without knowing actual workload patterns.
- Watch out
- Unified memory requires compaction to relocate live allocations during in-flight GPU operations, adding complexity to page lifecycle management and admission decisions.
