Compare LLM API Costs: Price Per Token for Leading Models in 2025

LLM API pricing data provides up-to-date cost information for major large language model (LLM) APIs, including those from OpenAI, Anthropic, Google, and others. This data allows users to compare costs across different AI models and identify the most cost-effective option for their specific use case. The information was last updated on July 25, 2025, at 01:51 PM. Current pricing is listed per 1 million tokens. The input and output costs vary by provider and model. Some models use tiered pricing based on prompt length, and the displayed prices are for prompts with 200,000 tokens or fewer. The data is sourced directly from official provider documentation, ensuring accuracy and relevance. The chart includes a range of models developed by various companies, with pricing details clearly outlined. Tokenization can differ between providers, but generally, a token is equivalent to 3–4 characters. Users are encouraged to consult each provider’s documentation for exact tokenization methods and pricing structures. This resource is maintained by @aellman and offers a valuable reference for developers, businesses, and researchers looking to optimize their AI costs. For those interested in staying informed, weekly updates on pricing changes and new model releases are available.
