Show HN: CostPerPrompt – Live AI API pricing and real-workload cost calculators (costperprompt.com)

A new tool, CostPerPrompt, has been launched to provide live pricing for over 232 AI models, allowing users to accurately calculate expenses related to API workloads in real-time. With a detailed pricing structure based on per-token usage, the platform enables developers and businesses to estimate their monthly costs for chatbots and other AI applications. The tool features a comprehensive table of model prices, including notable offerings like OpenAI's GPT-5.6 and Anthropic's Claude Fable 5, making it easier to compare costs across different vendors. This development is significant for the AI/ML community as it demystifies the often opaque pricing structures associated with AI models. Users can not only track costs better with real-time updates but also utilize the included calculators that factor in essential elements like prompt caching and batch processing discounts. By addressing common pricing issues often overlooked in typical cost estimates, CostPerPrompt empowers businesses to make more informed decisions, maximizing budget efficiency and ensuring the sustainable adoption of AI technologies.
