FAQs
-
Comet is an AI development management platform (MLOps) for developing, tracking, and evaluating machine learning and generative AI models.
Stay organized from model training, experiment comparison, performance evaluation, and post-deployment monitoring. -
Comet can be used through the web dashboard without installation. However, to track your machine learning experiments, you will need to install the Comet SDK in your Python code (pip install comet_ml).
-
Comet is especially useful for data scientists, machine learning engineers, generative AI developers, and others who need to iteratively experiment and manage models.
-
Yes, there are limits on the number of downloads per day depending on the type of account (free/paid). This applies either per account or per model version: - Free accounts can download up to 1,000 downloads per day on an account-wide basis, with a limit of 1,000 downloads per model version - Paid plan users can download up to 5,000 models per day, with a limit of 5,000 downloads per model version.
-
Answer. Comet throttles the rate so that you can only download up to 20 models per second. If you exceed this limit, Comet returns a 429 Too Many Requests error.
-
Basic experiment tracking, model recording, and LLM evaluation features are free and sufficient for personal research or small-scale testing.
-
You can email support@comet.com으로 or contact us on the official Comet Slack channel for assistance with raising your download limit.
-
An "experiment" in Comet is a single run of model training. It allows you to automatically record and compare logs, metrics, parameters, etc. that occur during training.
-
Yes, you can. Comet supports team-based workspaces where you can share, compare, and collaborate on experimental results in real time.
