Hi, I'm Jakub

Engineer & founder moving into AI-safety research: mechanistic interpretability, superposition and how neural networks represent what they know. MFF UK Prague · Co-founder & CTO at Zoplio.

Research

  • absorption-atlas: metric-validity audit of SAE feature absorption beyond first-letter spelling (Gemma-2-2B/9B, Gemma Scope): the SAEBench-standard projection metric reports above-null absorption where the causal ablation metric finds zero absorbed tokens. 15-page technical report + code.
  • superposition-phases (in progress): where do SGD-learned superposed codes sit relative to theoretical capacity ceilings? A toy-model study aimed at reconciling the 2026 compressed-computation debate.
