Jannes Gladrow

ML engineer building models and systems for AI, with earlier work across physics, optical computing for drastic FLOPs/W improvements in AI inference, and stochastic thermodynamics.

I work on machine learning systems and model research. My recent work spans post-training, agentic harnesses, large-scale language modeling, fixed-point models, and optical computing for drastic FLOPs/W improvements in AI inference.

Previously I was at Microsoft Research Cambridge and before that I did a PhD in Cambridge on stochastic thermodynamics, optical tweezers, and machine learning.

Selected work

Projects

Analog optical computer for AI inference

A compute architecture that combines optics and analog computation to improve efficiency for AI inference and certain optimization problems, alongside model designs that fit the machine.

Implicit language models are RNNs

Work on implicit state-space models that recover non-linear state transitions with more parallelizable training, scaled to reasoning tasks and large language-model pretraining.

Inverse digital holography using conditional generative models

Conditional generative modeling for phase retrieval in digital holography, aimed at finding holograms that produce small laser patterns with high accuracy.

Faster-than-free-diffusion reaction rates

Experimental work on tuned barrier shapes showing regimes where reaction rates can increase rather than decrease with barrier height, against the usual Arrhenius intuition.

Symmetry breaking of transition-path times

Experimental and theoretical work on when fundamental inversion symmetries in first-passage and transition-path dynamics hold, and how they break down on mesoscopic and molecular scales.

Broken detailed balance in living and active systems

A line of work on non-equilibrium dynamics in biological and active-matter systems, including broken detailed balance in living systems and active filament networks.
