Holotron 3 Nano

H CompanyOpen WeightsPending Human Review

Holotron 3 Nano is H Company’s Nemotron 3 Nano Omni-derived vision-language policy for computer-use agents. The hybrid Mamba/attention mixture-of-experts backbone has a 30B language tier with about 3B active per token and a native 262,144-token configuration. Post-training on proprietary agent data improves multi-step visual workflows and interface grounding, while the vision encoder supports varied screenshot resolutions. The April 28 release provides downloadable weights under NVIDIA model terms and made the model available in HoloTab. This record covers text and image understanding explicitly described for the released agent model, without assuming every audio/video capability of its Omni backbone.

Holo4 27B

Holo4 27B is H Company’s computer-use vision-language model built on Qwen3.8-27B. It is post-trained to work across graphical interfaces, code, MCP tools, and APIs, using screenshots and tool results to choose its next actions. Released weights support local agent research; an external harness executes clicks, typing, and code and returns observations. The dense 27B model uses a non-commercial weight license, unlike the Apache-licensed sparse Holo4 tier. Its card specifies a 262,144-token configuration limit; this is not a promise of consistent task performance throughout that window.

Holo4 35B-A3B

Holo4 35B-A3B is H Company’s computer-use vision-language model built on Qwen3.6-35B-A3B. It is post-trained to work across graphical interfaces, code, MCP tools, and APIs, using screenshots and tool results to choose its next actions. Released weights support local agent research; an external harness executes clicks, typing, and code and returns observations. The sparse model activates about 3B language parameters per token but still needs memory for its full checkpoint. Its card specifies a 262,144-token context. Apache-licensed weights and hosted H Models API access are available.
