Description
Holo4 is H Company's new series of agentic models, in 27B dense and 35B-A3B mixture-of-experts sizes, with open weights on Hugging Face (CC BY-NC 4.0). The same model clicks and types on a screen, writes and runs its own code, and calls MCP or API tools, on desktop, web, Android, a code sandbox or business APIs. On OSWorld 2.0 the 27B scores 61.7% at a much lower cost per task than frontier models, and every benchmark trajectory is open to replay.

Could you build this?
No Training custom multi-modal agentic foundation models (27B and 35B MoE) capable of computer use and tool calling requires millions of dollars in compute, specialized ML pre-training/RL infrastructure, and proprietary multi-modal datasets.
What it would actually take: Requires high-performance GPU clusters running distributed training frameworks (like Megatron-LM or DeepSpeed) on massive curated datasets of web, GUI, and API trajectories. Fine-tuning uses complex RL with verifiable rewards (RLVR) or reinforcement learning from AI feedback to achieve accurate mouse, keyboard, and code invocation actions.
