Wow, language models can talk without words.
A new framework, Cache-to-Cache (C2C), lets multiple LLMs communicate directly through their KV-caches instead of text, transferring deep semantics without token-by-token generation.
It fuses cache representations via a neural projector and gating mechanism for efficient inter-model exchange.
The payoff: up to 10% higher accuracy, 3–5% gains over text-based communication, and 2× faster responses.

Huge computer science result:
A Tsinghua professor JUST discovered the fastest shortest path algorithm for graphs in 40yrs.
This improves on Turing award winner Tarjan’s O(m + nlogn) with Dijkstra’s, something every Computer Science student learns in college.
