TokenGate Prunes Tokens to Speed Long‑Context Prefill Up to 11.3×

Stanford and UC Berkeley researchers released TokenGate, a drop‑in token pruning module that reduces long‑context prefill latency by 1.4×‑11.3× and peak memory by 1.5×‑3.4× without accuracy loss.

Why it matters

TokenGate’s faster prefill enables products to offer longer prompts without latency penalties.
