Users want to run the same computer-use capabilities across desktop and mobile environments, with seamless integration with different agent frameworks. They want deployment flexibility, from cloud inference to fully local execution on end-user devices.

This is why we are releasing the Holo3.1 family. Holo3.1 improves robustness across the three dimensions that matter most in production: environments (web, desktop, mobile), agent frameworks, and deployment targets. For the first time, we release quantized checkpoints optimized for local inference, including FP8, Q4 GGUF, and NVFP4.

Holo3.1 is a major step toward our vision of universal computer-use agents: systems that can operate across environments, integrate into any agent stack, and run wherever the workflow lives.

Based on the Qwen family, Holo3.1 was designed to improve robustness across the environments where computer-use agents are actually deployed, while retaining state-of-the-art performance.

As teams moved Holo3 from evaluation to production, we repeatedly observed the same challenge: strong performance in one setting does not necessarily transfer to another. Mobile devices, alternative agent harnesses, and different execution frameworks all introduce their own sources of distribution shift.

Holo3.1 expands Holo3's capabilities beyond browser and desktop control, delivering major gains on mobile environments. On AndroidWorld, our 35B-A3B model improves from 67% to 79.3%, while the smaller 4B and 9B variants improve from 58% to 72%.

To better support teams deploying Holo inside third-party agent stacks, Holo3.1 introduces native support for function-calling protocols in addition to the structured JSON outputs already available in Holo3.

Across OSWorld and our internal benchmark suite covering e-commerce, business software, and collaboration workflows, function-calling and native execution now achieve near-parity performance.
