OpenAI Chief Executive Officer Sam Altman has acknowledged that last year’s launch of the GPT-5 language model fell short of expectations and alienated many of ChatGPT’s “hundreds of millions” of users. Speaking at a private dinner with reporters in San Francisco, Altman said, “I think we totally screwed up some things on the rollout,” marking his most candid assessment to date of the product’s reception. Altman said the company is accelerating work on GPT-6 to regain momentum but warned that industry-wide shortages of high-performance graphics-processing units could delay the model’s debut. He offered no timetable for release, adding only that the next iteration would arrive “faster” than its predecessor if sufficient compute capacity can be secured.
