Hi, I'm Doruk Özgen.

I build SaaS products and do AI and machine learning research, with a background in QA automation.

Right now I'm building Fleetify, a command center for AI agents, and training language models from scratch as a Freya (YC S25) Research Fellow.

PaliGemma 2 Research Review

2026 · In Turkish

Research Paper · Vision-Language Models

A review of Google's PaliGemma 2 paper that asks whether model size or image resolution pays off more. Covers the SigLIP and Gemma 2 architecture and the staged training, then compares both ways of scaling over 42 benchmarks: going from 224 to 448 px lifts scores by 8.4% on average at 4.6× the compute, going from 3B to 10B parameters by 4.5% at 3.7×.
