OpenAI published its DevDay 2026 recap covering ChatGPT, Codex and API announcements. Highlights include GPT-6.1 Sol, Dots agents for ongoing work and faster output options.
Not every announcement is available to every user, region or plan. Before building around a new feature, check the official product page for current access, pricing and limits.
For hands-on learning, choose one feature and build a small test that measures quality, speed and cost. That is more useful than trying every announcement at once.
