What happened and what to do
Published on October 13, 2025, the paper describes InfLLM-V2, a system that switches between dense and sparse attention to adapt processing to short and long sequences. It discusses bottlenecks in processing long contexts and limitations of existing trainable sparse-attention methods.
A company evaluating models for lengthy documents could compare this approach with its current setup using representative tasks and data. Practical work could measure latency, memory use, and answer quality across context lengths, then present the results in a dashboard to support architecture choices.
