How Tensor Product Attention Redefines Long‑Context Transformers

The article analyzes the Tensor Product Attention (TPA) method presented at NeurIPS 2025, explaining how it factorizes Q, K, V tensors to drastically reduce KV cache size and attention complexity, and demonstrates superior convergence, lower perplexity, and faster inference on long‑sequence tasks compared with existing attention variants.
