The post makes a blanket claim that mathematicians have stopped using OpenAI. That is contradicted by direct evidence from 2026 showing named mathematicians continuing to use OpenAI products.

• In a September 19, 2026 WIRED report, NYU mathematician Tristan Buckmaster is described as still using OpenAI tools even after accusing OpenAI of copying his approach: "In the week and half since the New York University professor accused OpenAI of copying his approach, Buckmaster has been using the company's coding agent Codex to tidy up his research papers."
• The same WIRED report says German mathematician Andreas Thom "has continued to use ChatGPT ... to speed up writing papers because it is 'extremely efficient.'"
• In his own July 11, 2026 blog post, Fields Medalist Terence Tao wrote that he was using modern AI assistance to migrate old mathematical applets and to build new ones. That is direct first-person evidence that at least one prominent mathematician was still using AI tools associated with this ecosystem during 2026.
• In a March 4, 2026 OpenAI Forum transcript, Tao also said of AI math tools: "we just use them all the time" and "I already use it."

Because the statement is universal/plural in form, these counterexamples are enough to show it is false. Some mathematicians have criticized OpenAI, limited their use, or changed privacy settings — but that is not the same as mathematicians having stopped using OpenAI altogether.
