AI Model API Prices on OpenRouter
We record the input and output prices per million tokens of 466 AI models from 60 providers as OpenRouter lists them. These are listed prices, not a billing test, and model quality is not rated. Prices as shown in 2 countries — the United States and Switzerland — on ; the rows mix countries, and each plan page names its own.

What typical tasks cost
Per-token prices are hard to compare, so we priced three typical tasks (1,000 chat replies, summarizing 100 documents and a day of coding assistant use) on 15 current models. At the providers' own prices, 1,000 chat replies cost from $0.25 (GPT-6 Luna) to $25.00 (Claude Fable 5.1 and GPT-6 Astra). Calculated LLM API pricing comparison by task
Not building on an API? Ready-made AI tools for writing, speech and images charge per month or per credit instead of per token: AI tool prices and the usage each plan includes.

Unknown means no value was recorded at our latest check; it is never shown as zero. Prices in USD as OpenRouter lists them; we do not add taxes.
How these numbers are produced
Each row is one model at one provider in our ai-models section. Prices are the input and output prices per one million tokens from the latest check of that model; the context length is the value read on the same pass. The table is sorted by our latest output price, lowest first; rows without an output price come last. The order is by price only.
A provider gets its own page when we track at least 5 of its models.
Each model links to its page with dates, the source link and the full history.
What changed
Listed prices on OpenRouter move often. Confirmed changes in AI model prices, subscription limits and terms are listed day by day on What changed in AI models, prices and terms; every model page keeps its own history.
