Holo4 lets one agent work across screens, code, and APIs
Holo4 gives developers one model for desktop, web, Android, code sandboxes, and business APIs, so they do not need a separate agent for each interface. It clicks and types, writes and runs code, or calls MCP and API tools depending on the task. The 27B model scores 61.7% on OSWorld 2.0, versus 81.8% for Opus 5.5, while H Company says it costs much less and uses orders of magnitude fewer parameters.
