What is Neptune.ai?

Make every model decision searchable, comparable, and auditable

Neptune centralizes model metadata so researchers and MLOps teams can move beyond spreadsheets and ad hoc folders. Log hyperparameters, metrics, artifacts, and images from any framework, then compare runs across experiments to decide what to promote. Tags and custom dashboards make it simple to track milestones, monitor long trainings, and share progress with stakeholders. The model registry supports versioned stages and approvals for auditability. Workspaces, projects, and roles keep multi team access sane and API keys control integration points. Popular SDKs and callbacks mean you add a few lines and keep coding in PyTorch, Keras, XGBoost, or custom loops. For security conscious teams, private deployments and SSO are available. Neptune aims to be the place where every training run and model decision is searchable and trustworthy months after it shipped.

Key Capabilities

What makes Neptune.ai powerful

SDKs and callbacks

Add a few lines to send metrics params and artifacts from PyTorch Keras XGBoost or custom loops into a searchable store.

Implementation Level Intermediate

Runs at scale

Use tags filters and charts to find the best runs and understand tradeoffs across experiments.

Implementation Level Intermediate

Versioned models

Promote versions through stages with approvals so rollback and audits are straightforward.

Implementation Level Professional

Enterprise controls

Adopt SSO private deployments and role based access to meet security and compliance needs.

Implementation Level Professional

Professional Integration

These capabilities work together to provide a comprehensive AI solution that integrates seamlessly into professional workflows. Each feature is designed with enterprise-grade reliability and performance.

Key Features

What makes Neptune.ai stand out

  • Flexible logging: Track metrics params artifacts and images from any framework using light SDKs and callbacks
  • Search and compare: Slice runs by tags configs and scores to pick winners with evidence not memory
  • Custom dashboards: Build live charts tables and tiles to monitor long trainings and share status
  • Model registry: Store versions stages and approvals so releases are auditable and reversible
  • Collaboration: Organize workspaces projects and roles so large teams stay coordinated
  • Artifacts: Keep predictions checkpoints and plots alongside metrics for reproducibility
  • SSO and privacy: Use enterprise auth and private deployments for regulated environments
  • Integrations: Connect notebooks CI and orchestration tools for end to end workflows

Use Cases

How Neptune.ai can help you

  • Track baselines and ablations to defend decisions in reviews
  • Monitor long running experiments and intervene when metrics drift
  • Promote models through staged approvals with clear lineage
  • Share results with PMs and leads using links and dashboards
  • Attach artifacts so future teams can reproduce findings quickly
  • Automate comparisons in CI to block regressions before merge
  • Centralize model metadata to satisfy audit requirements
  • Create a living catalog of production models and research

Perfect For
