Comet vs OpenAI FAQ

Which one is cheaper?
OpenAI is the cheaper option, starting at $8/mo vs $19/mo for Comet.
Can I use either one for free?
Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.
How do they charge?
Different approach here. Comet uses hybrid pricing, while OpenAI goes with per-seat. That changes the math depending on your team size and usage.
Which one is a better deal?
Depends on what you need. Comet: At $19/mo for Pro, Comet undercuts most enterprise-first MLOps and LLM observability tools that gate everything behind a sales call — this is a land-and-expand play aimed at developers and small teams who'd otherwise bounce off a 'contact us' wall. OpenAI: At $20/mo, Plus sits right at the now-standard price point for consumer AI subscriptions (matching Claude, Gemini Advanced), so they're not competing on price at the mid-tier — they're competing on being the default. The $8 Go tier is a newer, cheaper wedge clearly aimed at price-sensitive users tempted by free alternatives, while Pro at $100+ chases power users and prosumers away from needing API access.
