    Review provided by G2
    What do you like best about the product?
    It has easy experiment tracking and smooth integration with tools like PyTorch Lightning, which makes logging metrics and comparing runs very simple
    What do you dislike about the product?
    The tracked-hours pricing can become expensive when running multiple experiments in parallel. The dashboard also slows down with large logs, and offline sync isn't always reliable after interrupted runs. Improving performance, sync stability, and making pricing more predictable would make the overall experience much better.
    What problems is the product solving and how is that benefiting you?
    Earlier, we relied on Excel sheets and screenshots to track experiments, which made comparing models and managing runs quite messy. Now W&B automatically logs metrics, hyperparameters, resource usage, and predictions in one dashboard. Comparing runs is much easier, the whole team has better visibility, reports are easy to share, and hyperparameter sweeps have saved us a lot of manual effort while making experiments more reproducible.

    Review provided by PeerSpot

    What is our primary use case?

    I use Weights & Biases primarily for experiment tracking, logging metrics such as loss and accuracy, learning rate, and other parameters. It helps in visualizing training progress in real time, particularly for deeper projects involving dataset modeling, CI/CD pipelines, and similar tasks.

    I used Weights & Biases in my personal project involving self-generating adversarial networks, where I tracked generator and discriminator losses over time, logged sample outputs, and compared architectures and hyperparameters. Those losses helped me analyze my model to optimize it so that they became negligible or minimal. Weights & Biases provides real-time dashboards, image logging, experiment comparison, and other useful features.

    One thing I appreciate about using Weights & Biases is how it fits into the bigger picture of ML workflows. As a developer, I can integrate end-to-end workflow integrations, which include data pipelines to track, model registry to store and manage, and deployment monitoring, so that I can analyze how models are performing, the losses, and the gains. It also supports hyperparameter tuning and model comparisons, including the comparison of losses and gains. In my opinion, it is a research notebook experiment collaboration tool.

    Using Weights & Biases gave me the ability for faster development and also saved my time since analyzing the discriminator and generator losses, which would have taken a lot of time if I did it manually, was done very easily with Weights & Biases. The graphs it provided were also very helpful in analyzing the gains and losses and the accuracy of the generator and discriminator model.

    What is most valuable?

    The best features that Weights & Biases offers include experiment tracking to monitor accuracy, loss, and learning rate in real time, visualizing the training process with dashboards. Additionally, it automates testing of hyperparameter configurations for different models through the hyperparameter feature. Weights & Biases has a model registry to version data, models, prompts, and code, ensuring reproducibility by linking experiments. Weights & Biases also has an integration ecosystem that works seamlessly with frameworks like PyTorch and TensorFlow.

    What needs improvement?

    Deployment and monitoring stands out as a feature I wish had further improvement. When I used it, it served as a fine-tuned model directly from Weights & Biases, providing automations for CI/CD pipelines and machine learning.

    From my perspective, I don't think Weights & Biases needs significant improvement, but areas involving more image tracking and additional integrations with tools like PyTorch or TensorFlow would be beneficial. I would prefer some AI tools to be integrated, such as Vercel or Netlify for deployments, as that would create ease of use for developers.

    In terms of Weights & Biases's AI capabilities, I believe improvements can be made regarding governance and security. In the AI world, many organizations struggle with securing their codes effectively, so if Weights & Biases introduced features related to security score levels, it would be helpful in enhancing security and strengthening code in a cohesive manner.

    Review from a verified AWS customer

    What is our primary use case?

    My main use case for Weights & Biases is tracking metrics for my models when I'm training or testing new models.

    I can give a quick specific example of how I use Weights & Biases to track metrics during my model training or testing by setting up the script to send my metrics when I'm training models in my Jupyter Notebook.

    In addition to tracking metrics, I also track down errors, precisions, and recalls.

    What is most valuable?

    In my opinion, the best features Weights & Biases offers are that they are easy to adapt and navigate through inside their UI, and I can check the model artifacts by versions. Sometimes when it throws errors, I can check them easily, and it has access control that's a good fit for corporate usage.

    What I like about the UI and the access control features is that they are just easy to navigate, easy to understand, and finding is also easy.

    Weights & Biases has positively impacted my organization a lot because many users are using Weights & Biases for tracking models and seeing metrics. I believe it places a lot less weight on setting up this tracking method.

    I can share specific outcomes or metrics since using Weights & Biases. For example, I can check each epoch's model artifacts and see how effectively it worked on my evaluation set, and it can be fetched by the unique ID.

    What needs improvement?

    I think Weights & Biases can be improved by being more stable because sometimes we have a lot of network issues and it's hard to debug. Also, there are some minor UI bugs where some graphs in specific formats don't show.

    I would add that their documentation is not easy to go through, and when I'm trying to deploy to Kubernetes, their examples are huge and really difficult to understand.

    I have been using Weights & Biases for three years.

    What do I think about the stability of the solution?

    Weights & Biases is stable.

    What do I think about the scalability of the solution?

    Since Weights & Biases is running on AWS on our side, I think it's pretty scalable for now, but I want to expand it to Kubernetes.

    How are customer service and support?

    Their customer support is great because they have 24/7 support and created separate Slack channels for our company users.

    Which solution did I use previously and why did I switch?

    I didn't previously use a different solution; I was just using a notebook.

    Which other solutions did I evaluate?

    Before choosing Weights & Biases, I wasn't in a position to evaluate other options, but somebody did.

    What other advice do I have?

    My advice to others looking into using Weights & Biases is to try it out first and also look at the other options, as it's hard to switch when you are used to Weights & Biases's UI. Other than that, I think it's just about trying to understand the real metrics and concept.

    I would rate this product a 7 out of 10.
