OpenAI DevDay: Dots, the Decisions API and GPT-6.1 Sol

OpenAI shows approximately 20 new features at its DevDay. Javi and Rafa select three: Dots, the Decisions API and GPT-6.1 Sol. The Decisions API is the OpenAI version of decision models like Jev. Also, Codex CLI gets a new full-screen interface that is more similar to Claude Code.

GPT-6.1 Sol gives almost the intelligence of Astra at one fifth of the price. It costs half the price of Opus 5.5. Cached input costs half the price of Sol 6, and in a normal conversation it is approximately 80% of the tokens. Sol 6.1 at medium effort also works very well for computer use. Rafa gives a caution: without Opus 5.5 last week, the impact would be larger.

Dots is a persistent assistant that runs 24/7 in ChatGPT. It uses Astra, and its primary use is included in the plan. The Codex tasks that it starts use your quota, like a normal task. Dots coordinates subagents in separate conversations, connects to Slack and accepts voice calls while you send it text.

Javi tests Dots for two days. The key change is that Dots is reactive: it reads Slack through MCP and tells you things without a request. Javi sees a risk in Slack: another person can ask about your calendar, and only the model decides to answer or not. He also sees a strong vendor lock-in: the more connectors you add, the more difficult it is to change assistants. Watch in the video.
