[Question] Deepseek R1 Distill Qwen 1.5B converted models have very large VRAM requirement.

[bhushangawde]

I checked multiple converted deepseek r1 distill qwen 1.5B models on MLCChat app on iPhone 15 Plus and Google Pixel 8 pro. But all of them have a very high GPU memory requirement due to which it fails on iOS and Android both.

I tried with 3 models https://huggingface.co/mlc-ai/DeepSeek-R1-Distill-Qwen-1.5B-q4f16_1-MLC https://huggingface.co/mlc-ai/DeepSeek-R1-Distill-Qwen-1.5B-q0f16-MLC https://huggingface.co/mlc-ai/DeepSeek-R1-Distill-Qwen-1.5B-q4f32_1-MLC

Is there a way to make this run on smartphone?
