5-day tasks by September 2026.

OpenAI said today their models can now work autonomously and uninterrupted for ~5 hours. I believe that’s true—I’ve had sessions where agents ran on their own for nearly 2 hours.

5-day tasks by September 2026. 🤔

OpenAI said today their models can now work autonomously and uninterrupted for ~5 hours. I believe that’s true—I’ve had sessions where agents ran on their own for nearly 2 hours. Right now, the main limitation is commercially imposed.

My hunch is that Anthropic and OpenAI will soon introduce a higher-tier, thousand-dollar plan that removes these artificial breaks, allowing models to iterate for hours—or even days—without stopping.

They’ve even set a target for the next milestone: 5-day tasks by September 2026.
