With the rapid development of generative AI and intelligent agents, self-hosted intelligent systems are gaining increasing attention from developers and technical teams. Clawdbot is one such open-source, self-hostable personal AI assistant. It not only engages in conversation with users but also executes tasks, integrates with messaging platforms, provides automation capabilities, and can be deployed on cloud platforms like Azure. This article will step-by-step introduce Clawdbot’s capabilities, architecture, and how to deploy and start using it on Microsoft Azure....

At the end of 2025, Microsoft Research released an open-source large model project for 3D content creation called TRELLIS, accompanied by the academic paper “Structured 3D Latents for Scalable and Versatile 3D Generation”. This project significantly improves the quality and flexibility of text/image-to-3D asset generation through a unified structured latent space and advanced flow model technology. It also expands the multi-format output and editing capabilities of 3D models, making it one of the key technologies in the current 3D AI model ecosystem....
