OpenAI Cuts Model Prices Amid Enterprises’ Concerns About AI Spend

Justin Sullivan via Getty ImagesOpenAI has dramatically reduced the price of two of its ChatGPT-5.6 models in an apparent effort to encourage enterprise takeup.A July 30 post on the OpenAI website confirmed that the cost of GPT-5.6 Luna, the generative AI vendor’s fastest and most affordable model, will drop by 80%, while the mid-tier GPT-5.6 Terra, designed for everyday work, will cost 20% less.The price of the flagship Sol model is unchanged, although OpenAI says it is now faster in the API.All three models were introduced three weeks ago.According to OpenAI: “These updates help customers get more from every dollar they invest in AI and move faster when time matters.”The cuts come amid growing concerns about the cost of AI, as evidenced by a recent vendor survey that showed that spend has grown rapidly among enterprises with little accountability and companies having little idea if their investment is paying off.In June, for example, Uber attracted attention when it placed a cap per employee on AI expenditure.Related:Prompt: Enterprises Grapple With Cost of AI ScaleOpenAI’s move also reflects the increasingly competitive market, in which cut-price Chinese models from vendors such as Alibaba and Moonshot are vying with offerings from U.S. tech giants such as Google and Microsoft.And it shows again how keen OpenAI is to keep the pressure on Anthropic, with both companies proceeding toward going public.The cuts have been enabled by efficiency gains from OpenAI’s latest foundation model, GPT-5.6, during its development, OpenAI said. “Our strategy remains focused on advancing both capability and efficiency so each generation of intelligence can accomplish more work at a lower cost,” the vendor said in a statement.The reductions have already kicked in, with API pricing at $2 per million input tokens and $12 per million output tokens for Terra, and at $0.20 per million input tokens and $1.20 per million output tokens for Luna.In comparison, Anthropic’s mid-tier Claude Sonnet 4.6 costs $3 per million input tokens and $15 per million output tokens.Fast mode for GPT‑5.6 Sol replaces Priority Processing in the API and is claimed to operate at speeds more than two-and-a-half times faster than standard processing.About the AuthorContributing WriterGraham Hope has worked in automotive journalism in the U.K. for 26 years, including spells as editor of leading consumer news website and weekly Auto Express and respected buying guide CarBuyer.
