It handles both English and Chinese and is optimized for interactive dialogue. It specifically features built-in tool calling capabilities in XML and JSON formats, allowing for direct integration into agent systems that invoke external APIs or functions. It features a structure that separates and outputs complex reasoning processes using thinking tags.

Compatibility with major inference frameworks such as vLLM, SGLang, and Docker has been confirmed, making deployment environment setup easy. It can also be integrated with Hugging Face's Inference Endpoints, and in local environments, it can be loaded and used directly via the Transformers library.

It is suitable for developers requiring Chinese-based services or multilingual support. Teams building their own LLMs or integrating open-source models into existing pipelines may consider Nanbeige4.3-33B as an alternative model.
