Comet vs DeepSeek FAQ

Which one is cheaper?
One or both use custom pricing, so it depends on your specific needs.
Can I use either one for free?
Comet has a free plan. DeepSeek doesn't — you'll need to pay from day one.
How do they charge?
Different approach here. Comet uses hybrid pricing, while DeepSeek goes with usage-based. 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. DeepSeek: This is the low-cost challenger play against OpenAI and Anthropic, winning developers and cost-sensitive API shops who care more about price per token than brand safety. The pricing listed here is 'Custom' rather than published, which is a bit surprising for a usage-based API and means you'll have to check their live rate card before benchmarking. The half-price off-peak window is a clear pitch to batch and async workloads that can shift to quieter hours.
