Frequently Asked Questions
How are prices calculated?
Monthly costs are calculated based on your estimated token volume and input/output ratio. We multiply input tokens by the model's input price and output tokens by the output price.
What is the Value Score?
The Value Score is a composite metric (0-100) that considers the blended token price and context window size. Higher scores indicate better price-to-capability ratios.
Are these prices accurate?
Prices are sourced from official API documentation of each provider. However, providers may update pricing — always verify with the official source before committing.
What's the difference between input and output tokens?
Input tokens are what you send to the model (prompts, context). Output tokens are what the model generates in response. Output tokens are typically 2-5x more expensive than input tokens.
