Methodology
How we collect prices and how the ranking is calculated.
Where prices come from
Official prices come from vendor pricing pages (Anthropic, OpenAI, Google, xAI, DeepSeek, Moonshot). Provider prices come from their public pricing pages. Every quote is stored with its source link and observation date.
How the ranking is calculated
Each board is one model. Providers are sorted by how many tokens the budget buys at the selected input:output ratio (1:1 by default): tokens = budget ÷ blended price per 1M tokens. The savings percentage compares the provider price with the vendor's official price at the same ratio.
What is not included
Only published input and output prices count. Subscription plans, top-up bonuses, cache rates, payment fees, speed, uptime, privacy and the legal standing of a service are not part of the score. Open the provider page before you pay.
Currency
All prices are normalised to USD per 1M tokens. When a provider lists prices in CNY we convert at the observation-date rate and keep the original value.
Referral links
“Visit site” buttons route through our redirect and may carry a partner code. Commission never affects ranking position or the price you pay. Outbound links are marked sponsored.
Reporting an error
Tell us and we will verify the price and update the quote. If the error is on the provider side, include the date and a link to their pricing page.
