LLM log probs approx lie on low dimensional ellipses which are hard to "forge", check out Matt's cool work :)
We discovered that language models leave a natural "signature" on their API outputs that's extremely hard to fake. Here's how it works 🔍

Every Language Model Has a Forgery-Resistant Signature
The ubiquity of closed-weight language models with public-facing APIs has generated interest in forensic methods, both for extracting hidden model details (e.g., parameters) and for identifying...

🚀 By *learning* to compress the KV cache in Transformer LLMs, we can generate more tokens for the same compute budget.
This unlocks *inference-time hyper-scaling*
For the same runtime or memory load, we can boost LLM accuracy by pushing reasoning even further!
