OpenAI details Recursive Self-Improvement and the view inside its research

Bulletin. September 6, 2026.

OpenAI published a piece titled “Research acceleration: The view inside OpenAI,” dated today, describing internal work the company refers to by the acronym RSI, for Recursive Self-Improvement. According to commentator Simon Willison, the piece does not expand the acronym for readers, treating the term as already familiar to its audience.

The same day, OpenAI Chief Scientist Jakub Pachocki published a companion essay, “An Alien Mind,” which Willison notes also discusses RSI. Willison observes that the coincidence of two pieces on the same subject, published on the same day, suggests a coordinated release, which he characterizes informally as “RSI day” at the company.

Willison’s commentary states that the “Research acceleration” piece includes details on how OpenAI’s internal research process operates, though the available material does not further specify the content of those details.

Willison further suggests, as his own interpretation rather than a claim made by OpenAI, that RSI may represent the company’s current framing of its pursuit of artificial general intelligence.

No further particulars of either publication’s content are available in the material reviewed for this bulletin. Readers seeking the full account are directed to the original OpenAI pieces, “Research acceleration: The view inside OpenAI” and “An Alien Mind,” both published September 6, 2026, and to Simon Willison’s accompanying commentary.
