Key Features
- Schema driven indexing: Define document fields and types for consistent ingestion and ranking features across collections
- Hybrid retrieval support: Combine text matching and vector similarity in one query pipeline for better recall and precision
- Ranking control: Configure ranking expressions and features to align results with business and relevance goals
- Streaming updates: Ingest and update documents continuously for near real time freshness in search results
- Low latency serving: Designed for fast query serving at scale with predictable performance under load
- Deployment flexibility: Run as a self managed service so teams control compute sizing and operational policies
- 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
- Site search upgrade: Replace basic site search with tuned relevance and faster retrieval across large content catalogs
- Product discovery: Blend keyword intent and embedding similarity for product search where naming varies by user
- Personalized feeds: Rank content per user signals using features and learned models for home and discovery surfaces
- Enterprise knowledge: Build internal search over docs and tickets with freshness and relevance tuning for teams
- Recommendations engine: Serve related items and next best content using vector similarity and ranking features
- Search evaluation: Run offline and online tests to compare ranking changes and measure click and conversion impact
- 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
