Compare AI models side by side
Pick any two models to compare API price, context window, output limit and retirement dates, then see what your own usage would cost on each. Every number comes from Kingy's checked data and shows when it was last checked.

Side by side
What would it cost you?
Standard list rates only. Excludes prompt-cache discounts, batch and priority pricing, regional rates, tool fees and tax. Reasoning tokens count as output. A long-context rate applies when one request's input passes the model's threshold.
Prices of the main AI models
API prices, context windows and output limits for the main models from OpenAI, Anthropic, Google and other leading providers, from the same checked data as the comparison above. Pick any two in the tool to compare them side by side and work out your own monthly cost.
Of the human-reviewed models below, Claude Haiku 5.5 has the lowest standard output price right now ($0.5 per 1M output tokens, first price tier). Price per token is only part of the cost: a model that needs fewer attempts or shorter answers can cost less per finished task.

USD, standard list rates for the first price tier. OpenAI, Anthropic and Google prices are reviewed by a person; the others are read automatically from the official pricing page by fixed rules. A model whose price Kingy cannot confirm right now shows no number.
How this works
Prices come from the same checked data behind Kingy's AI cost calculator and the Kingy Facts API. OpenAI, Anthropic and Google prices are reviewed by a person and re-checked against the official pricing page every few hours. Prices for other providers are read automatically from their official pricing pages by fixed rules, and the table says so.
"Not confirmed right now" means Kingy could not confirm the price within its check window, so it shows no number. Use the official link instead. Retirement dates come from Kingy AI Deadlines. Every source re-check is logged in the public accuracy ledger.
Why isn't my model listed?
Only models with a tracked official price page are listed. Embedding, rerank and moderation models are left out because they have no output price to compare.
Does this show benchmarks?
It shows Kingy's own tests when a model has been through them: the AI Accuracy Index and Kingy's coding and data tasks. These are small tests, so read each one for its tasks and limits before generalising. Vendor benchmarks are left out, because results depend on the test and settings used; Kingy's full comparisons cover them when one exists for your pair.
