ModelBest - 面壁智能

ModelBest is a Beijing-based artificial intelligence company that develops efficient, edge-deployable large language models. The company is headquartered at Tsinghua Science Park, Building 3F, in Haidian District, Beijing. Its flagship product line is the MiniCPM series, a family of compact foundation models designed to run directly on smartphones, PCs, vehicles, and other resource-constrained devices rather than requiring cloud GPU clusters. The series spans multiple parameter sizes, including MiniCPM 1.2B, 2.4B, and 4B variants, alongside multimodal extensions: MiniCPM-V, which processes video, images, and text together, and MiniCPM-o, which supports real-time streaming multimodal interaction combining speech, vision, and language in a single end-to-end model. According to company material and industry reporting, MiniCPM models have been integrated into Samsung Galaxy AI features and into automotive cockpit and driving-assistance systems, reflecting a focus on on-device inference where latency, privacy, and power consumption matter as much as raw model scale. Beyond the core model series, ModelBest has built vertical applications on top of its foundation models. Lantai Ling is a legal-AI expert system composed of 18 specialized agents intended to support legal research, drafting, and case analysis. Pinea is positioned as an end-side intelligent assistant, and the company also develops GUI Agent technology that allows a model to perceive and operate graphical interfaces autonomously, completing multi-step tasks the way a human user would. ModelBest maintains an open-source presence, publishing model weights and tooling under the OpenBMB organization on GitHub and Hugging Face, which has made MiniCPM one of the more widely downloaded Chinese-origin open model families for on-device deployment. In mid-2026, the company was reported to have raised RMB 5 billion in a funding round that brought its valuation to approximately USD 2.8 billion, reflecting investor interest in efficient, deployable AI as an alternative to purely cloud-hosted large models. The company's stated vision, expressed as "intelligence serves all things," centers on making capable AI accessible across many device types and industries rather than concentrated in a small number of hyperscale data centers. Target customers span consumer electronics makers embedding on-device assistants, automotive OEMs building cockpit and driver-assistance software, and enterprises seeking domain-specific agents such as legal research tools. Contact channels published on the company website are segmented by function, including dedicated addresses for business development, media relations, investor relations, and recruitment, indicating operations at meaningful commercial scale.
