Weights & Biases — Free Plan for Startups

Deal Highlights

Weights and Biases — ML Experiment Tracking for AI Teams

Weights and Biases (W&B) is the most popular platform for tracking machine learning experiments. Log hyperparameters, metrics, model artifacts, and datasets — then visualize, compare, and reproduce experiments across your team.

Every Experiment, Tracked

Add two lines of code and W&B captures everything: hyperparameters, metrics over time, system resources, model checkpoints, and dataset versions. No more spreadsheets tracking experiments. No more lost model configurations.

Interactive Dashboards

Compare experiments side by side with interactive charts. Filter by hyperparameters to find what works. Share dashboards with your team. The visualization alone saves hours of analysis per week.

Sweeps

Automated hyperparameter optimization. Define a search space, choose a strategy (grid, random, Bayesian), and W&B runs experiments and surfaces the best configuration.

W&B vs MLflow

MLflow is open-source and self-hostable. W&B has better visualizations, team collaboration, and a more polished experience. MLflow for self-hosted simplicity. W&B for team productivity.

Pricing

Free for individuals with unlimited experiments. Teams at $50/user/month adds collaboration features.
