Bilal Khan

Hi! I'm a fourth-year undergraduate software engineering student at the University of Waterloo.

I most recently worked on scaling large mixture-of-experts language models (萌えs) as an intern on the pretraining team at Databricks/MosaicML. Previously, I was a student researcher at Google Brain on the algorithmic efficiency team (machine learning optimizers and training efficiency) hosted by Zachary Nado. Before that, I spent two amazing internships as an early engineer at Co:here where I wrote TensorFlow and JAX to scale the training of LLMs to exaflop-scale TPU clusters and lead development of a new LLM inference runtime to serve our first O(50B) LLM to users. In my free time you can probably find me working, travelling, eating, or playing League/Valorant.

Training a 36B-132B mixture-of-experts large language model trained for a total of 3e24 FLOPs. I mostly worked on training stability, scaling laws for MOEs, efficiency, and adaptive computation.

We introduce the AlgoPerf: Training Algorithms benchmark — a competitive, time-to-result benchmark on multiple workloads running on fixed hardware for systematically comparing training algorithms. We construct baselines by defining search spaces for eight popular optimizers (AdamW, NadamW, Heavy Ball, Nesterov, LAMB, Adafactor, SAM(w. Adam), and Distributed Shampoo) that includes both popular optimizers that represent current practice and methods that have received attention in the recent literature and compare their performance on our benchmark.
