FAQ
LLM API pricing
How are AI API costs calculated?
Most LLM APIs charge separately for input tokens and output tokens. Some providers also offer batch, cached input, marketplace, or enterprise tiers.
What is the cheapest AI API?
The cheapest option depends on the model, provider, source type, region, usage volume, and whether you optimize for input price, output price, latency, or reliability.
Why do input and output token prices differ?
Output tokens usually cost more because generating responses consumes more inference resources than reading prompt input.
