Experiment Tracking

with W&B Dashboard

Store all your hyperparameters and output metrics in one place to effortlessly track experiments and reproduce models.

Hyperparameter Optimization

with W&B Sweeps

Quickly launch hundreds of parallel experiments to optimize your model.

Model Management

with W&B Artifacts

Track the whole machine learning pipeline from dataset versions and preprocessing to production.

"W&B was fundamental for launching our internal machine learning systems, as it enables collaboration across various teams."

Hamel Husain
GitHub

"W&B allows us to scale up insights from a single researcher to the entire team and from a single machine to thousands."

Wojciech Zaremba
Cofounder of OpenAI

"W&B is a key piece of our fast-paced, cutting-edge, large-scale research workflow: great flexibility, performance, and user experience."

Adrien Gaidon
Toyota Research

Visualize your results anywhere. We offer cloud hosting, on-prem deployments, or a lightweight local version you can run on your laptop.

Fast Integration

Add just a few lines of code to your script to get the power of W&B logging.
We're framework agnostic.

import torch
import torch.nn as nn
from torchvision import datasets
import wandb

wandb.init()
...

Log Anything

Easily log metrics from your script to visualize results in real time as your model trains.

wandb.log({"acc": accuracy, "val_acc": val_accuracy})

Explore Everything

Peek under the hood and see what your model is producing at each time step.

wandb.log({"point_cloud": wandb.Object3D(point_cloud)})

Massive Scale

Tag, filter, sort, and group runs easily. Our service was built to handle thousands of parallel runs.

Example Projects

Keras MNIST Example
This sample project is classifying images of handwritten digits from the MNIST dataset.
iNaturalist Fine-Tuning
Stacey walks you through fine-tuning a Keras model to classify images of plants and animals.
Semantic Segmentation of 3D Point Clouds
Nick trained a model to take input of a point cloud representing a real world object and provide segmentation of the object into different parts.
