hliu.cc is Haotian Liu’s personal academic homepage, not a conventional AI app or online tool. The page describes his experience leading the Omni team at xAI, contributing to Grok-1.5V and Grok-2, and leading the development of Grok-3 Vision, Grok-3 Reasoning, and the Grok Imagine image/video generation model. It also lists representative papers from his PhD period and earlier work in vision-language models and computer vision.
Based on the page content, the site’s main value is as a research index. The most important thread is its coverage of LLaVA, LLaVA-1.5, LLaVA-NeXT, and related work on visual instruction tuning and multimodal large models, including improvements in reasoning, OCR, and world knowledge. The page also lists computer vision projects such as GLIGEN, ELEVATER, and YolactEdge, with arXiv, HTML, Code, Demo, or Video links provided for some papers. For researchers, it is useful for quickly tracing the author’s technical trajectory in multimodal models and finding entry points to open-source resources.
The website does not show any commercial pricing, free tier, subscription plans, or payment methods. It also does not present any API, SDK, or enterprise integration capabilities. Privacy policy information, data collection practices, and user data handling details are likewise not shown in the main content. As such, it should not be evaluated as an AI SaaS product that can be directly purchased or integrated.
The main advantage is its focus on cutting-edge multimodal AI, especially LLaVA and Grok-related vision/generation work, making it valuable for understanding the evolution of industry technology. Many paper entries include code and demo links, which helps with reproduction and deeper reading. The limitations are also clear: it is primarily a personal homepage, with no online product features, service support, Chinese documentation, SLA, pricing, or privacy disclosures. Ordinary users would find it difficult to use as a practical tool.
It is best suited to AI researchers, algorithm engineers, graduate students, and technical teams interested in vision-language models and image/video generation models. The page does not disclose access conditions from China, so network stability is unknown; payment is not relevant here. If you need ready-to-use alternatives, consider the LLaVA open-source project, Hugging Face model pages, or multimodal products such as GPT-4o, Gemini, Claude, Tongyi Qianwen VL, and GLM-4V.
