OpenAI says computer-use speed rose 10× in a year; Dota comparison remains a forecast

OpenAI’s computer-use speed has increased tenfold over one year, according to a speaker, though no measurement method was specified. The improvement was attributed to both the model and its harness: the model needs less time to choose a reliable next action, while the harness can run operations in parallel and reduce delays. A separate auto-review agent, internally called Guardian, watches the primary agent and can intervene if it is about to enter sensitive information on a questionable domain.

Astra’s ultrafast mode was cited at 300 tokens per second. Separately, the speaker estimated about 20 tokens per action and roughly 30 actions per second; how those estimates relate to the 300-token rate was not clarified. The speaker also forecast real-time computer actions within the next year and said a standard OpenAI model with computer use could beat the model from the company’s first Dota competition, whose 10-year anniversary falls next year. The comparison was described as potentially close because actions per minute matter alongside reasoning.
