What is Neptune?

Discover how Neptune can enhance your workflow

Neptune centralizes experiment metadata metrics and artifacts so ML teams can debug training faster and keep models reproducible. Engineers log losses gradients activations and custom metadata from any framework then slice runs by tags params or code commits. Dashboards render charts instantly even at high cardinality while alerts flag regressions and stalled jobs. Artifact management stores checkpoints predictions and datasets with versioning and lineage to the exact code and data used. Role based access SSO and audit logs meet enterprise requirements and ingestion SLAs ensure stability during big runs. Teams adopt Neptune to reduce wasted GPU cycles shorten iteration loops and create a durable history of how models evolved from baseline to production candidates. Self host and cloud options exist with published Startup and Lab tiers for foundation model scale and API compatibility across Python and popular orchestration stacks.

Key Capabilities

What makes Neptune powerful
