The announcements, made on September 29, highlight the company's growing focus on transforming AI from a conversational assistant into a platform capable of managing complex tasks, supporting businesses and enabling new software experiences.

The event introduced developments across ChatGPT, Codex, APIs, plugins and collaborative AI tools, reflecting OpenAI's ambition to make artificial intelligence more deeply integrated into everyday professional and digital activities.

AI Agents Move Beyond Traditional Conversations

One of the most significant themes of DevDay 2026 was the expansion of AI agents capable of handling ongoing responsibilities.

OpenAI introduced tools that allow developers to build AI-powered systems capable of interacting with software, using connected tools and completing multi-step tasks. These developments could change how businesses approach administrative operations, software development and customer services.

The company's Agents API now supports computer use, enabling developers to create applications in which AI agents can interact directly with software environments.

GPT-6.1 Sol Expands Advanced AI Capabilities

OpenAI also introduced GPT-6.1 Sol, describing it as a major upgrade focused on agentic coding, computer use and professional work.

The company said the model delivers advanced capabilities at significantly lower token prices than its more expensive intelligence tier, potentially making sophisticated AI workflows more accessible to developers.

The development demonstrates the industry's continued movement towards models that can do more than generate text, including reasoning through complex instructions and carrying out practical tasks.
