Assessment
Reasoning: An ML experiment-tracking and LLM-evaluation platform: what it holds is training runs, prompts, and evaluation data from an organisation's own AI work. The no-training terms toward OpenAI are clear; Comet's own log of prompts has no stated retention period and no storage location is named.
Flags: Storage location not stated · Prompt logs retained for an unspecified period · Assessed 2026-09-16. The assessment is Unseen's; the terms above are the vendor's.
