  • Weights & Biases (wandb): Tracks experiments, visualizes learning curves, and makes collaboration easy.

  • TensorBoard: TensorFlow’s dashboard that shows loss curves, learning rates, and computation graphs.

  • Neptune.ai: Focuses on tracking, comparing, and visualizing model training results across experiments.


Deployment & Monitoring:

  • Streamlit: An open-source app framework to quickly convert Python scripts into interactive web apps. Great for demoing AI models.

  • Flask + Heroku: Combines a lightweight web framework with a cloud platform to deploy custom AI APIs.

  • Gradio: Allows users to create easy-to-use interfaces for AI models and share them online with just a few lines of code.


Dataset Tools:

  • Labelbox: Helps with dataset annotation and managing labeled data for training models.

  • Roboflow: Offers tools for creating, preprocessing, and managing datasets—especially for computer vision.

  • Papers with Code: Connects research papers with code and benchmarks to find the most recent and effective implementations.


Cloud Platforms:

  • Google Vertex AI, AWS AI Services, Azure AI: All provide scalable infrastructure, automatic model tuning, and real-time prediction services.

Using the right tools ensures not just technical efficiency but also better collaboration, clearer insights, and faster iteration.
