OpenAI CEO Sam Altman said AI cost efficiency is the dominant topic at Sun Valley. His GPT-5.6 family targets lower compute cost, with stakes for NVIDIA and hyperscalers.
OpenAI CEO Sam Altman said the question dominating conversations at the annual Allen & Co. Sun Valley gathering is how to make artificial intelligence cheaper, according to an interview with CNBC on Monday.
Companies are increasingly focused on AI efficiency and return on investment, Altman told the network. The high cost of training and running large language models has become a central concern for executives allocating capital to AI infrastructure.
Altman positioned his company's forthcoming GPT-5.6 family as the answer. He described the new model as designed to deliver comparable performance at a fraction of the compute cost. He did not provide a release date or specific pricing.
The cost of inference – running models after training – is the variable that shapes whether AI applications scale profitably. Altman's claim that GPT-5.6 can match performance with less compute directly addresses that variable. The model's release date and pricing will determine whether the cost equation shifts.
Wall Street has sharpened its scrutiny of AI spending. Microsoft and Alphabet, along with Amazon, have each reported rising capital expenditure tied to data centers and chips. Investors are pressing executives on when those outlays will translate into proportional revenue.
For chipmakers, the direction of AI costs carries direct stakes. NVIDIA profile has ridden surging demand for its high-end graphics processors. Cheaper inference could broaden deployment. It could also reduce the need for the most expensive hardware if models become more efficient.
Altman's comments also touched on the competitive landscape. He noted that Chinese companies are making measurable progress in AI, a dynamic that adds pressure on U.S. firms to deliver cost reductions. Chinese firms like DeepSeek have demonstrated competitive model performance at lower reported costs, Altman acknowledged. Tencent in Talks to Become Top Investor in AI Startup Manus shows Chinese capital flowing into the sector.
The Allen & Co. conference draws top tech and finance executives. Altman's comments carry weight because OpenAI's spending trajectory influences the broader AI capex cycle.
The Sun Valley conference runs through Friday. Altman is scheduled to participate in a panel on AI infrastructure Wednesday.
