Add metadata and improve model card
Browse filesHi! I'm Niels from the community science team at Hugging Face.
This PR improves the model card for KernelGen-LM-4B by:
- Adding relevant metadata: `license`, `library_name`, and `pipeline_tag`.
- Linking the model to its research paper on the Hugging Face Hub.
- Adding a link to the official GitHub repository.
These changes help users discover the model and understand its capabilities and compatibility.

KernelGen-LM-4B is a state-of-the-art domain-adaptive large language model specialized for low-level NPU kernel generation, specifically for the Huawei Ascend architecture using the AscendC programming language. Built upon the Qwen3-4B backbone, it is trained on the Ascend-CoT dataset and refined via reinforcement learning with execution feedback.
