Sam Altman Explains Why OpenAI Killed Sora and Atlas to Focus on AGI

In a nearly 1.5-hour in-depth interview, Sam Altman reflected on OpenAI's decisions to cut the video generation model Sora and its in-house browser Atlas. The core logic: with limited compute, talent, and resources, the company must prioritize the directions most critical to achieving AGI—namely, knowledge work and science, as represented by Codex. Multiple bloggers (@sahilypatel, @tristanbob, @AI寒武纪, etc.) relayed the interview's key points.

Confirmed

OpenAI decided to shut down Sora and the Atlas browser project to concentrate resources on Codex. According to @sahilypatel, Altman said these products, while excellent and interesting, consumed massive compute and were less important than Codex, forcing a tradeoff.
Per @tristanbob, Altman anchored the company's priorities on AGI-related directions in knowledge work and science.
Per @AI寒武纪's interview recap, Altman made clear that OpenAI positions itself as a platform company rather than a vertical product company; the interview also covered the trajectory of large model technology, business strategy, and the company's early history.
Per a clip shared by @davidperell, Altman discussed how to treat ideas in a startup's early days: the best ideas are extremely fragile early on, and founders can either be distracted by good-but-non-core ideas or kill promising directions too early because they look bad at first.

Why it matters

It shows the real tradeoffs top AI companies make under compute constraints: even excellent products must give way to the AGI mainline.
Altman's remarks—"good ideas are the enemy of great founders" (relayed by @davidsenira) and "good ideas are extremely fragile"—offer founders a methodology for focus and judging early-stage directions.
