OpenAI DevDay 2026: GPT-6.1 Sol, always-on "Dots" agents and a $500 Pro plan

The headline everyone ran. A new model a week after the last one, and agents that keep working when you're not there.

At its DevDay on 29 September, OpenAI announced GPT-6.1 Sol, one week after GPT-6 Sol. It also launched "Dots", always-on agents for paid tiers, powered by GPT-6 Astra and supporting about 4,000 apps, along with a $500-a-month Pro plan. OpenAI said ChatGPT now has 1.2 billion weekly users.

It came against the background of OpenAI's earlier decision to hold back GPT-6.1 Astra on safety grounds.

Why it matters

The release pace is now weekly, and the product is shifting from a chat window to agents that run in the background.
