DevDay 2026: OpenAI Unveils GPT-6 Astra and 20+ New Announcements

What happened

OpenAI held DevDay 2026, its annual developer event, with more than 20 announcements. Highlights include GPT-6 Astra, along with updates for ChatGPT, Codex, the APIs, security and new tools for people building AI-powered solutions.

The official summary lists the areas covered, but the information we received doesn't include details on each feature, such as the new model's performance, pricing or availability dates.

What this means for your business

Even though it's a technical event, what launches at DevDay usually makes its way quickly into the tools small businesses use: ChatGPT itself, customer service chatbots, automation platforms and marketing software powered by OpenAI technology.

How to take advantage:

• Talk to your technology vendors. Ask whether the chatbot, CRM or content tool you use will adopt the new model and what changes in practice.
• Rerun your tests. Prompts that gave mediocre results may perform better with new models, so it's worth revisiting ad copy, captions and scripts.
• Consider simple automations. API updates tend to make integrations cheaper and easier, such as automated replies and lead organization.
• Don't change everything at once. Test in one area, compare results and only then expand usage.
