@danieldk Hi, we have added support for npu to the kernels.

This pr is ready for review. Thanks!

danieldk · 2025-09-17T10:48:08Z

Thanks for the PR! Are you also planning to add support to kernel-builder (since it's the best way to build compliant kernels)?

danieldk

Bunch of suggestions, also some questions about compatibility between versions, etc.

Thanks for asking! Yes, we are actively working on adding npu support to kernel-builder.

@danieldk
All review comments have been addressed, and the code and tests have been updated. Could you please take another look? Thank you very much.

danieldk · 2025-09-19T12:03:11Z

Thanks for asking! Yes, we are actively working on adding npu support to kernel-builder

Nice! 🚀

I'll try to do another review pass today or Monday.

Okay, the user wants a short introduction to a large language model. Let me start by recalling what a large language model is. It's a type of artificial intelligence that can understand and generate text, right? So I should mention its ability to process and generate text. 

I need to keep it concise. Maybe start with a definition, then highlight key features like understanding and generating text. Also, mention its applications, like language translation or customer service. 

Wait, should I include something about how it's trained? Like using massive datasets and deep learning. That's important for explaining its capabilities. Also, maybe touch on its versatility in different languages. 

Avoid jargon. Keep it simple. Let me check if I'm covering all aspects: definition, key features, applications, training methods, and versatility. That should cover it. Alright, time to put it all together in a friendly, informative way.
</think>
content: A large language model (LLM) is an AI system designed to understand and generate human language. It can comprehend context, understand diverse languages, and create text, making it useful for tasks like language translation, content creation, and customer support. Developed through massive datasets and deep learning, these models are versatile and capable of adapting to various tasks.
