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.

Run instant rental-property math on any Zillow single-family listing
Tune rental rate, mortgage rate, vacancy rate and renovation estimates to see how each assumption moves cash-on-cash return and ROI.
Compare the projected profitability of up to 80 nearby single-family properties in a single click to spot the strongest candidates fast.
Five built-in AI prompts generate quick takes on renovation costs, market trends and other decision inputs that are awkward to look up manually.
Save results and export to CSV or PDF, and generate a homeowner/buyer summary that includes comps, neighbourhood and demographic context.
