Weights & Biases
About Weights & Biases
Weights & Biases is now CoreWeave Forge. It connects tools for running models and agents in one environment. Existing Weights & Biases credentials work with the platform.
Products
- CoreWeave Forge Inference: Runs open source AI models with per-model pricing.
- CoreWeave Sandboxes: Provides isolated, on-demand environments for running untrusted code.
- CoreWeave Forge ARIA: Serves as an AI research and iteration agent.
- Agent Lens and Weave: Monitors and analyzes GenAI model performance during development and production, capturing inputs, outputs, and metadata for each inference.
- Artifacts: Provides dataset and model versioning.
- Tables: Provides interactive data visualization.
Used for
- Training and fine-tuning AI models.
- Monitoring GenAI model performance in development and production.
- Comparing recipes such as fine-tuning, RAG, LLMs, and datasets for accuracy, latency, and token usage.
- Monitoring the performance, cost, and health of LLM applications.
- Coordinating projects remotely for academic research.
Who it is for
- Individuals working on personal development of AI applications and models.
- Professionals working to optimize AI applications and models.
- Companies prioritizing security and compliance for AI applications and models.
- Early-stage teams with fewer than 50 employees.

How to evaluate ML Platforms & MLOps
This is how the CIOPages Research Team evaluates this category. It is not an assessment of Weights & Biases. The category covers two kinds of product, so both frameworks are here. Most buyers need one of them.
AI/ML Platforms
25%
MLOps, Serving & Lifecycle
Reproducible training pipelines and CI/CD for models, a first-class model registry with versioning and stage promotion, real-time and batch/streaming serving, A/B and canary rollout, automated retraining, and rollback — the path from registered model to monitored endpoint and back
20%
Model Development & Experimentation
Notebook and IDE experience, experiment tracking and run comparison, feature engineering and a feature store, AutoML for breadth, distributed training, and support for the frameworks your teams use (PyTorch, TensorFlow, scikit-learn, XGBoost, Spark ML)
20%
AI Governance & Responsible AI
End-to-end lineage from data to deployed model, approval workflows and access control, bias and fairness testing, explainability, model and prompt audit trails, and the evidence trail needed for internal risk review and emerging AI regulation such as the EU AI Act
15%
GenAI & LLM Operations
Managed serving and fine-tuning of open and proprietary LLMs, a vector/retrieval layer for RAG, prompt management, evaluation harnesses for non-deterministic output, agent orchestration hooks, and token and inference cost controls — weighted to how central GenAI is to you
10%
Data, Compute & Cost Control
Proximity to where your data already lives and the egress it avoids, GPU availability and scheduling, spot/preemptible support, autoscaling, idle-resource reclamation, and chargeback/showback visibility so AI spend is attributable and governable rather than a surprise
10%
Platform Openness & Ecosystem
Portability and exit cost (open formats, MLflow compatibility, container-based serving), multi-cloud and on-prem reach, breadth of integrations, collaboration across data science and engineering, and standards conformance so the platform extends rather than confines your stack
MLOps Platforms
25%
Production Monitoring & Reliability
Data and concept drift detection, prediction/quality monitoring, ground-truth join for delayed labels, alerting and automated retraining triggers, plus LLM-specific signals (hallucination, toxicity, response-quality eval) on live traffic
20%
Model Registry & Governance
Versioned registry with stage transitions and approval gates, end-to-end lineage (data → run → model → endpoint), reproducibility, model cards, audit logging, and alignment to your AI risk/inventory policy
20%
Deployment & Serving
One-step deploy to real-time and batch endpoints, autoscaling and GPU-aware serving, canary / shadow / A-B rollout, rollback, multi-model and multi-framework support, and latency/throughput under your traffic
15%
CI/CD & Pipeline Automation
Git-native pipelines, reproducible training/eval/deploy stages, integration with your existing CI (Actions, GitLab, Azure DevOps), environment/dependency management, and IaC-friendly APIs
10%
Experiment Tracking & Reproducibility
Run logging at scale, metric/artifact comparison, hyperparameter sweeps, dataset and code versioning, collaboration, and a durable system-of-record across teams and frameworks
10%
LLMOps Coverage
Prompt and version management, eval datasets and LLM-as-judge scoring, RAG/agent tracing, online evaluation in production, and a path to manage classical models and LLMs through one stack
