Show HN: Free OCR Cost Calculator – Estimate multi-provider LLM token costs (ocrbench.app)

A new free OCR cost calculator has been launched, enabling users to estimate the token costs of various LLMs (Large Language Models) when processing documents. This tool helps bridge the knowledge gap regarding LLM OCR pricing, which often involves complex calculations of input and output tokens based on the specific model used. Users can upload documents or select from samples, allowing them to see real-time estimations for costs across different models, such as GPT-6 Luna and Claude Opus 5.5, which can vary significantly—by as much as 43 times in some instances. The significance of this tool lies in its ability to demystify the pricing structure of LLMs for OCR, helping businesses choose cost-effective solutions without sacrificing accuracy. The calculator accounts for number of tokens based on document type and quantity, presenting a clear overview of expected costs per document and monthly expenditure. Additionally, it provides insights on how to optimize costs through document preparation and model selection, emphasizing the importance of considering both pricing and accuracy metrics before committing to a provider. This innovation supports a more informed decision-making process in the AI/ML community, particularly in applications involving document processing.
