Comet Transitions to Flat-Rate Pricing Model, Introducing Trace-Based Metrics and Unlimited Team Members for Pro and Free Plans
What happened
Between the Oct 1, 2024 and Jan 1, 2025 captures of Comet's pricing page, Pulse recorded 7 changes: Free plan now has explicit trace limit: '10k traces per month' (previously had undefined 'fair usage policy'); Comet restructured pricing from per-user training hours model to flat-rate trace-based model. Pro plan changed from '$39 Per user/month' with '1500 training hours included' to '$39 Per month' with '100k traces per month'. This represents a shift from MLOps-focused pricing to LLM Evaluation (Opik) focused pricing; Primary usage metric changed from training hours to traces. Overage pricing changed from '$1/training hour' to '$8/100k traces'; Pro plan now has explicit trace limit: '100k traces per month' (replaces training hours metric); Pro plan training hours limit removed: '1500 training hours included' no longer exists (replaced by traces); Pro plan user limit increased from 'Up to 10 users' to 'Unlimited team members'; Free plan team members increased from '1 platform user' to 'Unlimited team members'. Pulse files it as a packaging change (limit lowered, packaging change, metric change, limit raised). Pulse's latest capture (Nov 9, 2026) lists Opik Pro Cloud at $19, MLOps Pro at $19, Additional Spans at $5 per 100k spans, Additional Span Retention at $29 per 100k spans retention and Additional Training Hours at $1 per training hour.
Comet's previous recorded change was "Comet Pro Plan Price Decreased by 22% and Capacity Increased to 1500 Training Hours" (Q3 2024). Comet has been tracked since 2023-11-14.
