ABOUT PAULINA PRACHNIO JANUŠAUSKAS

Co-founder at neptune.ai: Experiment tracker purpose-built for foundation model trainingWe help AI researchers monitor, debug, and evaluate foundation model training. Whatever scale is necessary.Speaking to teams training foundation models, we realized that logging internal model metrics is essential. But logging, storing, browsing, and analyzing them in real-time, especially at scale, is hard with current tooling. With Neptune you can monitor thousands of per-layer metrics—losses, gradients, and activations—at any scale. Visualize them with no lag and no missed spikes. Drill down into logs and debug training issues fast. Keep your model training stable while reducing wasted GPU cycles.You can play with an example project with thousands of metrics per run and millions of points in the workspace. Browsing logs and visualizations are snappy.We work with top teams training foundation models like poolside, Instadeep, Thinking Machines, Gingko Bioworks, HeyGen, Biooptimus and others. Vadim Markovtsev, Founding Engineer at poolside“I really appreciate that I’ve never seen any outage in Neptune. And since we’re training an LLM, that it’s super critical to not have any outages in our loss curve. Other than that, there are things you often take for granted in a product: reliability, flexibility, quality of support. Neptune nails those and gives us the confidence.”
