    The short answer · 14 words

    In short

    Platform for experiment tracking, model management and evaluation of machine learning and LLM applications.

    Flow-alerta.cab (2026): Comet. https://flow-alerta.cab/en/glossar/comet. Editorially reviewed on: 09 October 2026.

    How much detail would you like?

    Practical

    Relevant for teams that need to systematically compare, reproduce and monitor models or LLM applications.

    Example scenario: A team logs several fine-tuning runs, compares metrics and documents the model that goes into production.

    Use for own ML or LLM development if experiments are to be documented in a comprehensible, comparable and cross-team way.

    At a glance

    Core
    Comet here refers to the ML platform Comet ML, not a browser of the same name. It logs training runs, parameters, metrics and artifacts and supports comparison and reproducibility. For LLM and agent applications, Comet also offers Opik with evaluation and production monitoring.

    ELI5 – Explained simply

    Comet is a digital laboratory book for ML experiments: it records what has been tested and how well it has worked.

    Why it matters in practice

    Relevant for teams that need to systematically compare, reproduce and monitor models or LLM applications.

    Example

    Example scenario: A team logs several fine-tuning runs, compares metrics and documents the model that goes into production.

    Pitfalls and limits

    • Compare experiments without code and data versioning; consider only best values; upload sensitive artifacts unchecked.

    Origin & history

    Comet evolved into an ML platform for experiment management and production monitoring and expanded its offering to include LLM evaluation and observability.

    Use in mid-sized companies

    • Use for own ML or LLM development if experiments are to be documented in a comprehensible, comparable and cross-team way.
