InstantML is an experiment-tracking service for logging machine-learning runs, comparing metrics, inspecting artifacts, and exporting data.
What InstantML is
InstantML is an experiment-tracking service for logging machine-learning runs, comparing metrics, inspecting artifacts, and exporting data. It is available through the web and an API, with a Python SDK using init, log, and finish calls; the quickstart specifies Python 3.11 or newer. Charts support streamed scalar series, grouped averages, smoothing, zoom, and hover readouts. Configs, metrics, tags, artifacts, histograms, and media are queryable, and the SDK buffers logs and spools them offline when the network drops. Teams can import W&B, MLflow, and Neptune JSON, or shadow W&B scalar logs during migration. PyTorch, JAX, and TRL are also listed. Artifacts and checkpoints can use customer S3 or R2 storage. The Free plan includes 2 seats, 2 GiB hosted storage, 2 projects, 100 runs, 1M metric points, and 500k API requests per month. Pro costs $199 a month; Premium costs $699 a month. Premium offers a BYOC GCP ClickHouse option, while artifact bytes remain on InstantML-hosted object storage.
