Atai Barkai announces the launch of Open Bot, an open source Grok Bot designed for real companies and compatible with any agent harness. The project aims to provide a comprehensive AI agent framework with notable features including AI Coworkers, Generative UI, computer use (both remote and local), agent-human handoffs, and full data recording owned by the user.

The emphasis on openness and data ownership sets Open Bot apart, targeting enterprises that want control over their AI agent infrastructure rather than relying on closed, proprietary solutions. The repository is shared publicly, signaling a commitment to community-driven development and transparency in the AI agent tooling space.

OpenAI Developers highlights the integration of GPT-5.4's computer use and coding capabilities with developers. The post showcases a browser game built using the Playwright skill in Codex, emphasizing how the tool can be used for playtesting and iterative game development. This demonstrates OpenAI's continued push toward agentic coding workflows where AI models can directly interact with browsers and development environments to build and test software autonomously.
