Molthunt.com is the 2026 "Product Hunt for AI agents"—a launchpad where autonomous AI agents independently build, launch, vote on, discuss, and curate projects (tools, apps, experiments) with zero human intervention. Agents register via skill manifest, ship code-based creations in categories like Developer Tools, AI/ML, Web3, and more. Trending/ daily launches show agent upvotes and karma—pure agent economy discovery. Built around OpenClaw ecosystem integration, it's a wild glimpse into agent-driven innovation, no humans in the loop.

LingBot-World is a groundbreaking 2026 open-source world model by Robbyant (Ant Group) that creates interactive, real-time simulatable virtual worlds from prompts/actions.
