OpenAI introduces agents API to simplify agent development

On September 14, 2026, OpenAI unveiled four product updates, including a new Agents API that transforms Codex into a cloud service. This API allows developers to create intelligent agents with minimal effort, as it handles orchestration, execution, and hosting through a single API call. This shift marks OpenAI's move from selling models to fostering a developer ecosystem. The new API reduces the need for developers to build complex context management systems, enabling small teams to deploy applications directly on OpenAI's platform. The competition in the execution framework space is intensifying, with DeepSeek, Anthropic, and Google each advancing their strategies. Google holds a full-stack advantage with its models, tools, and office suites, though integration remains a challenge. Meanwhile, Chinese tech firms are also vying in the office scenario, leveraging their platform strengths to enhance agent capabilities.
