Cloud providers such as Tencent Cloud, Alibaba Cloud and ByteDance, as well as third-party API service providers such as SiliconFlow, can directly use this open-source framework to improve efficiency and reduce costs.
The multi-in-one architecture used by Lawyer Xiaofang includes SiliconFlow's model foundation, PKULaw (the officially certified 'ammunition depot' of the legal world), and the firm's in-house agent 'Qianwen Office'.
The author used DeepSeek R1 on the SiliconFlow platform for a fingerprint test, and the result was identified as Claude Haiku 45 2025 1001, released 9 months later, with a probability of 100%.
SiliconFlow has launched the SIM 4.0.29 BA4B model with free API access; the model natively supports a 256K context window and specializes in complex engineering and long-horizon agent tasks.
The project can run normally on VPS servers in mainland China but with network restrictions, and it is recommended to use domestically accessible APIs (such as SiliconFlow) or locally deployed Ollama models
When using online APIs, query text and knowledge base fragments are processed through third-party platform servers, so scenarios involving trade secrets or personal privacy require careful compliance risk assessment.
Domestic AI model aggregation platforms similar to OpenRouter include Siliconflow and 302.AI.
