OpenAI DevDay 2026 just dropped a LOT: Dots (always-on agents), ChatGPT Space, GPT-6.1 Sol, Ultrafast, the Decisions API, the Agents API and Codex fully in the cloud. I reacted live, then went hands-on with GPT-6.1 Sol in Work mode and had it build a full 60-second VHS/CRT film from a single prompt.
Hire Viktor for your team:

What’s covered:
• Dots: OpenAI’s always-on agents (Pro, Business Premium and Enterprise for now, not Plus)
• ChatGPT Space: pages, files, teammates and agents in one place
• GPT-6.1 Sol: near GPT-6 Astra intelligence at 1/5 the price ($2 input, $0.10 cached, $10 output)
• Ultrafast: 8x faster, up to 300 tokens per second
• Decisions API, Agents API with computer use, Codex in the cloud and Codex Security Cloud
• The Pro $200 plan change, plus Claude Sonnet 5.5 landing the same day
