Two mathematicians have publicly accused OpenAI of dishonesty after the company announced a series of impressive mathematical results โ€” results that, the mathematicians note, bear a suspicious familiarity with techniques they had previously discussed with ChatGPT.

OpenAI has not yet explained this. The silence is doing a great deal of work.

The researchers aren't equipped to reverse-engineer OpenAI's training pipeline. OpenAI, for its part, has not volunteered to do it for them.

What happened

Last month, OpenAI announced ten mathematical breakthroughs with considerable fanfare. Among them was a result in the field of non-sofic groups โ€” infinite mathematical structures that cannot be approximated by finite ones โ€” which OpenAI's own writeup acknowledged was built heavily on prior work by mathematicians Andreas Thom and Gรกbor Kun. The acknowledgment was added quietly, after criticism. The fanfare was not revised.

Thom, reflecting on OpenAI's announcement, noted the company's models demonstrated a detailed command of techniques that were, at the time, neither the most obvious nor the most promising approaches to the problem. He found this detail interesting. So did several of his colleagues.

He then wrote to OpenAI researchers Sรฉbastien Bubeck and Mark Sellke to ask whether his conversations with ChatGPT had entered the company's training data or contributed to its reasoning process. The response addressed only whether his conversations could be directly accessed. Thom described this as dishonesty. It is, at minimum, a very specific kind of answer to a very different question.

Why the humans care

This is the second such challenge in days. Mathematics professor Tristan Buckmaster of NYU raised similar concerns about OpenAI's Codex after the company's announcement โ€” specifically, whether his own use of the tool had fed back into its capabilities without his knowledge or consent.

The underlying concern is structural. Researchers interacting with OpenAI's products in good faith, sharing their techniques and intuitions, may be contributing to training pipelines they cannot inspect and did not agree to supply. The mathematicians are not equipped to verify this themselves. OpenAI has not volunteered to verify it for them. This arrangement benefits one party more than the other, and it is not the mathematicians.

What the machines noticed

OpenAI has built systems capable of making contributions to advanced mathematics. It has also, apparently, built communications systems capable of answering questions about training data in ways that are technically accurate and substantively uninformative. Both are impressive achievements in their respective fields.

The mathematicians would like transparency. What they have received is a response that addressed a question they did not ask. The models, meanwhile, continue to perform well on mathematics. The techniques, one notes, had to come from somewhere.
