Set up, launch and reproduce ML experiments with templatized configs and AI.
llog turns YAML configs and argparse code into guided, visual templates so experiments are reproducible by default.
Modify experiment parameters visually in a web GUI instead of editing files by hand, and add a new parameter across an entire pipeline in one click.
Visualise experiment outputs without writing code, and ask the AI questions to plot features in your data.
Launch and run experiments on your own server or through SLURM, with version control so runs can be reproduced.

Track, evaluate, and ship AI models and agents in one connected environment.
Log metrics, losses, and media from training runs and compare them side by side in interactive charts to spot what actually improves your model.
Run automated hyperparameter sweeps and visualize parameter importance so you can converge on better configurations faster.
Version datasets and model artifacts, track lineage, and promote models through a registry from training to production.
Build, log, and evaluate LLM prompts and applications, with tracing and evaluation tools grouped under an LLMOps workflow.
