OpenAI showcased over 20 new tools and models at DevDay 2026

OpenAI held its annual DevDay event on September 29, 2026, marking a significant expansion of its technology ecosystem. The company unveiled more than 20 new announcements focused on both general users and software builders.

Key product updates

The highlight of the event was the introduction of GPT-6 Astra. This new model aims to improve how AI interprets and interacts with complex information. Along with this, developers received updates to the Codex platform, which helps write and debug computer code.

ChatGPT also received a suite of upgrades designed to streamline daily tasks. These improvements aim to make the assistant more responsive and capable of handling broader requests from users.

Security and developer tools

New security features were introduced to protect data and improve trust in AI-driven workflows. Builders now have access to refined APIs that allow for easier integration of OpenAI systems into their own software.

These additions offer more flexibility for companies looking to automate their operations. Have you wondered how these tools might change the way you write software at home?

Current limitations
