OpenAI, Anthropic cut AI fees in a row as it gets harder to keep users

OpenAI and Anthropic have repeatedly cut large language model (LLM) usage fees from the summer through autumn of 2026, driven by low user switching costs and price competition with open-weight models. On Oct. 29, online media outlet Gigazine reported that data scientist Max Woolf recently said the wave of price cuts shows a market structure in which it is difficult to lock users into a specific model. OpenAI cut the price of its low-cost model GPT-5.6 Luna by 80 percent on July 30. The input fee per 1 million tokens fell to $0.20 from $1, and the output fee fell to $1.20 from $6. OpenAI later released material comparing the cost efficiency of GPT-5.6 Luna with open-weight models including DeepSeek V4 Pro and GLM-5.2.
