Long Context

As context grows, attention cost and the KV cache grow with it. These posts generally take one of four routes:

  • Make attention sparse — hardware-aligned, natively trainable sparsity
  • Compress, then recompute — shrink the context and rebuild what is needed
  • Change the architecture — state-space models and their relation to Transformers
  • Absorb it in serving — parallelism for million-token requests
