What is PRISM for LLMs?

PRISM uses photonic circuits to select relevant KV cache blocks in O(1) time, cutting memory traffic 16x for long-context inference.

Can PRISM run on current GPUs?

No—needs photonic co-processors. Future chips only, maybe 2028+.

Paper claims 100% on benchmarks. Real tests pending. Wandered a bit there. Point is: PRISM's legit threat to status quo. Watch this space.

Your LLM's gasping on long contexts? PRISM beams in with photons to gut memory traffic 16x. Too sci-fi to work—or the real deal?
