Semantic Retention and Extreme Compression in LLMs: Can We Have Both?
arXiv 2505.07289 (opens in a new tab) · IJCNN 2025, Rome
Companion note
What Survives Compression
“Ask what meaning survived, not how fluent the remainder sounds.”
Extraction Arena
A strong average can hide a procedure the model gets entirely wrong. Gate the field you fear, not the mean.

About
// the short version
French AI Engineer in Warsaw. I build LLM systems and the evaluations that show whether they are ready to ship, and I co-authored an IJCNN 2025 paper on semantic retention under LLM compression.
