StreamForge streams 40GB models on 3GB VRAM

StreamForge is an open-source inference engine that uses asynchronous prefetching and sequential block execution to run massive transformer models on consumer GPUs. It enables 14B+ models to run in full bfloat16 precision on as little as 3GB of VRAM by keeping only one block in memory at a time.

// ANALYSIS

StreamForge proves that "out-of-memory" errors are often a software orchestration problem rather than a hard hardware limit.

–Exploits sequential block execution to DMA-transfer weights from CPU RAM just in time for GPU computation.
–Maintains full precision without the quality degradation typical of aggressive quantization.
–Successfully runs 80GB-class models like Wan2.2 I2V on mid-range RTX 3060 hardware.
–Performance hit is currently 30-40% slower than native, but offers a viable path for local high-end inference.
