According to CoinMeta, the cost of AI tokens has dropped to a historic low, and the price war between OpenAI is intensifying, leading to a decline in the price of AI tokens. This makes artificial intelligence more affordable for users, but it also presents growing profit challenges for OpenAI and Anthropic. According to the LLM Token Expenditure Index from Silicon Valley Data, the index fell to $0.97 on Monday, representing a decrease of over half from its peak this summer. Cheaper open-source and open-weight models, especially those developed in China, are providing companies with alternatives to the high-end products of OpenAI, Anthropic, and Google. OpenAI is also responding to market pressure by lowering the prices of some of its GPT-5.6 series products. Lower token prices are good news for developers and enterprises that undertake large-scale deployments of AI, but the economic situation is more complex for cutting-edge AI laboratories. Companies such as OpenAI and Anthropic have invested substantial funds in computing infrastructure, yet the fees per token are declining, which may lead to squeezed profit margins.
