零一万物

01.AI, known in Chinese as 零一万物, is an Artificial Intelligence company focused on building large-scale foundation models and putting them to work in real products. The company positions itself around the IDEa of a human-plus-AI Partnership, aiming to combine powerful models with prACTical tools that businesses and developers can adopt.

What it does

The company develops its own family of large language models, including open-weight releases that developers can download and run, alongside hosted models accessed through an API. Typical uses include conversational assistants, text generation and summarization, retrieval-augmented knowledge work, translation, and multimodal tasks where image understanding is involved.

Key capabilities

• Foundation Models spanning different parameter sizes, with some released as open weights for self-hosting.
• An API and model service for teams that want to integrate language and multimodal capabilities into their own APPlications.
• Support for long-context inputs and multilingual text, with stronger perfORMance reported in Chinese than in some Western benchmarks.
• Commercial solutions aimed at Enterprise customers, including deployment support and technical guidance.
• Public technical writing, model documentation, and recruitment for AI research and engineering roles.

Who it is for

01.AI suits developers evaluating open models against well-known alternatives, enterprises in Chinese-speaking markets that want local model providers, and research teams that need flexible access to foundation models. It is also relevant to product builders who want a hosted API rather than manAGIng their own inference infrastructure.

How to get started

Begin at the official website, where you can review the model lineup and documentation. Developers can register for API access and test requests against the hosted models, while teams interested in open-weight models can download them from their public repository listings. evaluation is usually the sensible first step: try a few Prompts that reflect your real workload, compare latency and ouTPUt quality, and confirm licensing terms before comMITting. Note that availability of specific models, API signup regions, and pricing can change, so verify current details directly with the provider.

Pricing and access caveat

Some open models are free to download and self-host, but hosted API usage is Generally metered and may require a paid plan or credits. Access from certain regions may be limited, and Chinese-language interfaces or account requirements may apply. Because model veRSIons, rate limits, and commercial terms shift over time, treat any figures you see as indicative rather than fixed.
