Qwen releases open-weight Drive 1.0-4B model for self-driving
Qwen released Qwen-Drive-1.0-4B, a finetuned version of its Qwen3.5-4B model built for driving, according to a post on the r/LocalLLaMA subreddit. The full BF16 checkpoint comes in at 9B parameters. The model is open weight, meaning researchers and developers can download and run it rather than access it through a closed API.
The release marks an early move by a Chinese AI lab into autonomous driving with openly available weights. Qwen's parent company Alibaba has been expanding its open-weight model lineup, and this driving-focused finetune extends that approach to a new domain.
The r/LocalLLaMA post, which noted the release had not been widely discussed on the subreddit, framed the model as part of a broader push by Chinese labs into self-driving. Details on the training data, benchmark results, and intended deployment scenarios were not included in the post.
An open-weight driving model from a major Chinese lab could let researchers study and build on autonomous-driving AI outside closed commercial systems.
