OpenRouter API pricing questions
How much does the OpenRouter API cost?
OpenRouter bills its language models per million tokens, with separate prices for input, cached input and output. On 2026-10-25, standard prices ran from $0.10 (Anthropic: Claude Haiku 5.5) to $4.00 (Anthropic: Claude Opus 5.5) per 1M input tokens, and $0.50 (Anthropic: Claude Haiku 5.5) to $20.00 (Anthropic: Claude Opus 5.5) per 1M output tokens.
Does OpenRouter offer a batch discount?
Its pricing page lists no batch price for the rows here. Inference is billed at the provider's list price on every plan. OpenRouter's fee is charged when you buy credits, never on single requests.
Where do these prices come from?
From OpenRouter's own pricing page, https://openrouter.ai/pricing, checked on 2026-10-25. Every row links to it. When a price cannot be confirmed, the row says to check the vendor's page instead of showing a number.
Does OpenRouter add a markup on model prices?
No markup on tokens. OpenRouter bills inference at the provider's list price and charges a fee when you buy credits: 5.5% on Standard and 8% on Business. With your own provider key, $25,000 of list-price inference a month carries no fee, then 5%.
