Claude is an AI assistant and large language model service from Anthropic, positioned for general conversation, writing, coding, analysis, and long-document processing. It is comparable to products such as ChatGPT and Gemini, and provides both a web interface and API access.

Claude is not an open-source project that can be directly self-hosted. It is typically hosted in Anthropic's official cloud, so users do not need to configure GPU resources themselves. Users in China should pay attention to access, payment, and compliance restrictions, as well as integration support in the WeChat ecosystem, domestic cloud platforms, and application service providers.
