HunyuanOCR vs. Holo4

Tencent Hunyuan is a diverse suite of multimodal AI models developed by Tencent, integrating various modalities such as text, images, video, and 3D data, with the purpose of enhancing general-purpose AI applications like content generation, visual reasoning, and streamlining business operations. This collection includes different versions that are specifically designed for tasks such as interpreting natural language, understanding and combining visual and textual information, generating images from text prompts, creating videos, and producing 3D visualizations. The Hunyuan models leverage a mixture-of-experts approach and incorporate advanced techniques like hybrid "mamba-transformer" architectures to perform exceptionally in tasks that involve reasoning, long-context understanding, cross-modal interactions, and effective inference. A prominent instance is the Hunyuan-Vision-1.5 model, which enables "thinking-on-image," fostering sophisticated multimodal comprehension and reasoning across a variety of visual inputs, including images, video clips, diagrams, and spatial data. This powerful architecture positions Hunyuan as a highly adaptable asset in the fast-paced domain of AI, capable of tackling a wide range of challenges while continuously evolving to meet new demands. As the landscape of artificial intelligence progresses, Hunyuan’s versatility is expected to play a crucial role in shaping future applications.

Holo4 is a family of agentic AI models developed by H Company for computer use and multi-step automation across desktop, web, mobile, terminal, MCP, and API environments. The series consists of Holo4 27B, a dense 27-billion-parameter model, and Holo4 35B-A3B, a 35-billion-parameter Mixture-of-Experts model with 3 billion active parameters. Rather than specializing exclusively in graphical interfaces or tool calling, Holo4 can click and type on screens, write and run its own code, and invoke MCP or API tools as different stages of a workflow require. The same model can therefore move between desktop applications, websites, Android applications, code sandboxes, and business APIs without switching to a separate model for each interface. H Company's Agentic Task Factory generated approximately 10,000 tasks across web applications, MCP servers, desktop software, and hybrid environments to support model development and evaluation. Holo4 underwent supervised fine-tuning on 127 billion tokens, with roughly three-quarters of that training data consisting of successful agentic trajectories covering desktop, web, MCP/API, and mobile tasks. Two reinforcement-learning experts were subsequently trained for desktop/web workflows and terminal/MCP/API workflows before being merged into the final generalist model. In H Company's evaluations, Holo4 27B scored 85.2% on OSWorld, 61.7% on OSWorld 2.0, 45.4% on AutomationBench, and 85.1% on AndroidWorld, although the company notes that reference-model results can use different harnesses and effort levels. Holo4 27B supports a 256K context window and is priced through the H Models API at $0.40 per million input tokens, $0.04 per million cached input tokens, and $3.00 per million output tokens. Holo4 35B-A3B also supports 256K context and is priced at $0.30 per million input tokens, $0.03 per million cached input tokens, and $2.00 per million output tokens.
