Andreas Thom says OpenAI's response to his questions about ChatGPT data use was "materially misleading" and "plainly dishonest"

Andreas Thom, a mathematician whose research overlaps with one of OpenAI's recent announced breakthroughs, has accused the company of "dishonesty" over its handling of questions about whether his interactions with ChatGPT contributed to its results, according to The Verge. The accusation comes days after a separate and bitter dispute erupted between OpenAI and New York University mathematics professor Tristan Buckmaster over the company's claimed solution to a Millennium Prize problem.

Thom said he began scrutinizing his own ChatGPT interactions after Buckmaster publicly questioned whether OpenAI's models had benefited from his use of the company's Codex tool. One of the 10 mathematical results OpenAI announced last month involved non-sofic groups, an area where Thom had done significant work, and OpenAI had already revised its writeup after facing criticism for failing to acknowledge contributions from Thom and fellow mathematician Gábor Kun, according to The Verge. Non-sofic groups are infinite mathematical structures that cannot be approximated by finite ones.
