Qwen3 4B
Qwen3-4B is a 4-billion-parameter foundation model hosted on Hugging Face. It is distributed as an open-source model under the Qwen organization repository.
The model page supplies a chat template written in Jinja2 that defines how conversation messages are formatted for inference. This template includes conditional logic for handling system prompts, multi-turn exchanges, and tool-calling scenarios. When tools are supplied, the template instructs the model to emit structured JSON objects wrapped in XML-style tool_call tags that contain a function name and an arguments object. The template also supports a multi-step tool-use mode and falls back to standard instruction formatting when no tools are present.
Qwen3-4B is delivered as downloadable model weights on the Hugging Face platform. It can be loaded through the Hugging Face Transformers library or compatible inference engines that accept the supplied chat template. The repository page itself contains no additional statements about training data, supported languages, benchmark results, or deployment formats beyond the template code.
