The ultimate aggregator cost estimator. Instantly compare and calculate costs for 100+ endpoints on OpenRouter from OpenAI, Anthropic, Google, and more.
Calculated based on OpenRouter 2026 unified pricing. Provider rates are directly mapped per 1 million tokens.
One API key to rule them all. OpenRouter provides a unified interface for hundreds of models, removing the need for separate integrations with OpenAI, Anthropic, Google, and diverse open-source providers.
Prices on OpenRouter stay in sync with underlying providers. Whether it's the premium **Claude Opus 4.7** or a newly released **GPT-5.4** variant, the aggregator ensures you pay exactly the list rate (plus occasional routing optimizations).
Routing to models with up to **2 million token context windows** (like Grok 4.20 or Lyria 3) is seamless. OpenRouter handles the complex handshake for these enormous prompts across diverse infrastructure.
Unique access to cutting-edge models from ByteDance, Alibaba, Xiaomi, and Chinese flagships like **MiMo-V2** which are often difficult to access directly via standard Western billing tiers.
OpenRouter generally passes through the provider's direct pricing. In some cases, they offer **routing discounts** or special negotiated rates for high-volume endpoints, which can actually make it cheaper than direct access.
Yes! OpenRouter supports vision models (like MiMo-V2-Omni), audio models (GPT-4o TTS), and even experimental video models as they become available. Use the calculator to estimate costs for these multi-modal endpoints.
OpenRouter respects the native context window of each model. A model like **Grok 4.20** allows for a massive 2,000,000 token context, while a nano-tier model might be limited to 4K or 8K.
