Holo4: A Model That Clicks, Codes and Calls Tools

Why it matters

The video introduces Holo4 as an open-weight model that can operate a GUI, write and run code, call MCP tools, and choose which capability to use at each step. Chapters also cover the agent loop, model variants, dense-versus-MoE trade-offs, benchmarks, and a demonstration.

Discuss: How does Holo4’s ability to switch among GUI actions, code execution, and MCP tools change what an agent can handle in one workflow?
