Thinking with machines.
This is the personal site of Lukas Stepanek: AI systems work, local inference, and trying to make a useful contribution to open AI/ML.
Technical work, field notes, and human-scale questions around AI systems.

Current signal
A contract for memory pressure.
I recently submitted a paper on resident-claim key-value cache behavior: a semantic contract for what runtimes should do when active KV pressure and resident KV blocks cannot fit in the same pool.
The focus is narrow: what the contract says, why it matters, and what it does not claim.

About
The person behind the work.
This site belongs to Lukas Stepanek, also known as krooksn / krx in some corners of the internet. I am an independent researcher and builder based in Vienna, with most of my work sitting around AI, machine learning, local inference, and autonomous agents.
I care about open-source work, serious technical practice, and a life that still has texture outside it.
