Our verdict: Comet ML
Best for teams wanting to both track classical model training and monitor LLM applications in production under one brand. Not for you if you are looking for a single, simple pricing structure: Opik and Comet's MLOps platform are billed separately, which can double the subscription for a team using both.
Our verdict: Weights & Biases
Best for research and data science teams wanting to visually compare dozens of experiments and collaborate without reinventing a dashboard. Not for you if you are tracing high volumes of LLM calls in production without monitoring costs: Weave ingestion beyond the Pro plan is billed per megabyte and can quickly exceed budget.
