Key Features
- Open-source core with identical APIs on managed Cloud
- Vector
- keyword
- and regex search for hybrid retrieval
- Usage-based pricing with a $0 starter and team plan
- Simple client libraries and docs for quick prototyping
- Experiment tracking: Log metrics and hyperparameters to compare runs and reproduce results across machines and teammates
- Artifacts and datasets: Version artifacts and datasets so training inputs and outputs remain traceable over time
- Collaboration workspace: Share dashboards and reports so teams align on model performance and release decisions
- System integration: Integrate logging into training code so observability is automatic not a manual reporting step
- Cloud or self hosted: Official pricing describes cloud hosted plans and self hosting for infrastructure control needs
- Governance at scale: Paid plans support org needs like security controls and larger team workflows
Use Cases
- RAG backends for chat and agents with hybrid filters
- Semantic search for docs
- notes
- and support portals
- Product search blending vector and keywords for relevance
- Analytics on unstructured text with metadata slicing
- Training visibility: Track experiments across models and datasets to find what improved accuracy and what caused regressions
- Hyperparameter search: Compare sweeps and runs to identify stable settings without losing configuration context
- Artifact lineage: Trace a model back to the dataset and code version used for training and evaluation evidence
- Team reporting: Publish dashboards for leadership that summarize progress and quality metrics over a release cycle
- Production debugging: Compare production failures with training runs to isolate data shift and pipeline differences
- Self hosted governance: Deploy self hosted W&B when policy requires tighter control of data access and storage
