IndexCache Accelerates Long-Context Inference 1.82x
💡1.82x faster inference on 200k tokens for DSA models—cuts prefill costs 75%
⚡ 30-Second TL;DR
What Changed
1.82x faster time-to-first-token and 1.48x generation throughput on 200k tokens
Why It Matters
IndexCache enables faster, cheaper inference for long-context AI applications like document processing and agentic workflows, benefiting enterprises deploying production-scale models. It preserves output quality while slashing prefill costs, potentially accelerating adoption of extended context windows.
What To Do Next
Test IndexCache integration on your DeepSeek or GLM models for 200k+ context inference.
Key Points
- •1.82x faster time-to-first-token and 1.48x generation throughput on 200k tokens
- •Cuts 75% redundant computation in DeepSeek Sparse Attention (DSA) indexers
- •Addresses quadratic complexity in DSA lightning indexer across layers
- •Leverages stable token selection for caching between consecutive layers
- •Tested on 744B-parameter GLM-5 model
