H Company Releases Holo1.5: An Open-Weight Computer-Use VLMs Focused on GUI Localization and UI-VQA

ByRicardo

H Company (A french AI startup) releases Holo1.5, a household of open basis imaginative and prescient fashions purpose-built for computer-use (CU) brokers that act on actual consumer interfaces by way of screenshots and pointer/keyboard actions. The launch consists of 3B, 7B, and 72B checkpoints with a documented ~10% accuracy acquire over Holo1 throughout sizes. The 7B mannequin is Apache-2.0; the 3B and 72B inherit research-only constraints from their upstream bases. The sequence targets two core capabilities that matter for CU stacks: exact UI factor localization (coordinate prediction) and UI visible query answering (UI-VQA) for state understanding.

Why does UI factor localization matter?

Localization is how an agent converts an intent right into a pixel-level motion: “Open Spotify” → predict the clickable coordinates of the right management on the present display. Failures right here cascade: a single off-by-one click on can derail a multi-step workflow. Holo1.5 is educated and evaluated for high-resolution screens (as much as 3840×2160) throughout desktop (macOS, Ubuntu, Windows), internet, and cellular interfaces, bettering robustness on dense skilled UIs the place iconography and small targets improve error charges.

How is Holo1.5 completely different from basic VLMs?

General VLMs optimize for broad grounding and captioning; CU brokers want dependable pointing plus interface comprehension. Holo1.5 aligns its knowledge and targets with these necessities: large-scale SFT on GUI duties adopted by GRPO-style reinforcement studying to tighten coordinate accuracy and resolution reliability. The fashions are delivered as notion parts to be embedded in planners/executors (e.g., Surfer-style brokers), not as end-to-end brokers.

How does Holo1.5 carry out on localization benchmarks?

Holo1.5 reviews state-of-the-art GUI grounding throughout ScreenSpot-v2, ScreenSpot-Pro, GroundUI-Web, Showdown, and WebClick on. Representative 7B numbers (averages over six localization tracks):

  • Holo1.5-7B: 77.32
  • Qwen2.5-VL-7B: 60.73

On ScreenSpot-Pro (skilled apps with dense layouts), Holo1.5-7B achieves 57.94 vs 29.00 for Qwen2.5-VL-7B, indicating materially higher goal choice beneath sensible circumstances. The 3B and 72B checkpoints exhibit related relative beneficial properties versus their Qwen2.5-VL counterparts.

Does it additionally enhance UI understanding (UI-VQA)?

Yes. On VisibleWebBench, WebSRC, and ScreenQA (quick/advanced), Holo1.5 yields constant accuracy enhancements. Reported 7B averages are ≈88.17, with the 72B variant round ≈90.00. This issues for agent reliability: queries like “Which tab is lively?” or “Is the consumer signed in?” cut back ambiguity and allow verification between actions.

How does it evaluate to specialised and closed techniques?

Under the printed analysis setup, Holo1.5 outperforms open baselines (Qwen2.5-VL), aggressive specialised techniques (e.g., UI-TARS, UI-Venus) and reveals benefits versus closed generalist fashions (e.g., Claude Sonnet 4) on the cited UI duties. Since protocols, prompts, and display resolutions affect outcomes, practitioners ought to replicate with their harness earlier than drawing deployment-level conclusions.

What are the mixing implications for CU brokers?

  • Higher click on reliability at native decision: Better ScreenSpot-Pro efficiency suggests lowered misclicks in advanced purposes (IDEs, design suites, admin consoles).
  • Stronger state monitoring: Higher UI-VQA accuracy improves detection of logged-in state, lively tab, modal visibility, and success/failure cues.
  • Pragmatic licensing path: 7B (Apache-2.0) is appropriate for manufacturing. The 72B checkpoint is at present research-only; use it for inside experiments or to sure headroom.

Where does Holo1.5 slot in a contemporary Computer-Use (CU) stack?

Think of Holo1.5 because the display notion layer:

  • Input: full-resolution screenshots (optionally with UI metadata).
  • Outputs: goal coordinates with confidence; quick textual solutions about display state.
  • Downstream: motion insurance policies convert predictions into click on/keyboard occasions; monitoring verifies post-conditions and triggers retries or fallbacks.

Summary

Holo1.5 narrows a sensible hole in CU techniques by pairing robust coordinate grounding with concise interface understanding. If you want a commercially usable base right now, begin with Holo1.5-7B (Apache-2.0), benchmark on your screens, and instrument your planner/security layers round it.
