DeepSeek-R1-Distill-Qwen-1.5B

This version of DeepSeek-R1-Distill-Qwen-1.5B has been converted to run on the Axera NPU using w8a16 and w4a16 quantization.

This model has been optimized with the following LoRA:

Compatible with Pulsar2 version: 4.2

Feature

• Support for longer contexts, in this sample it's 2k
• Support context dialogue
• System prompt kvcache is supported

System prompt cache

• The System prompt can be preset through the configuration file from --system_prompt
• The System prompt can be cached in the form of kv cache to a specified folder for quick loading at the next run time from --kvcache_path
• This folder needs to be created manually before running, for example mkdir kvcache
