Experimental streamed transformer inference for legacy GPUs.
N730 is an experimental AI inference runtime built to run modern Large Language Models on extremely low-end hardware such as the NVIDIA GT 730.
Instead of loading an entire model into VRAM at once, N730 streams quantized transformer layers dynamically during inference, allowing models far larger than GPU memory capacity to run on legacy hardware.
- Layer streaming runtime
- Dynamic mixed precision quantization
- Native AVX2/C++ backend
- CUDA acceleration for Kepler GPUs
- Runtime dequantization
- KV cache autoregressive inference
- HuggingFace conversion pipeline
- Converting HuggingFace transformer models into the
.n730format - Streaming 198+ transformer layers from disk in real time
- Running autoregressive transformer inference
- Dynamically dequantizing INT2 / INT4 / INT8 / FP16 weights
- Executing inference on hardware as old as the GT 730

N730 is an experimental research project haha.
Performance, correctness, and stability are not working send help pls
