Przełom paradygmatyczny od Microsoftu. BitNet b1.58 zastępuje 16-bitowe wagi trójwartościowymi {-1, 0, 1}, eliminując mnożenie macierzy (MatMul) na rzecz prostego dodawania — oferując ekstremalną szybkość i wydajność na CPU.

The cheapest GPU that runs BitNet b1.58 locally (min 3 GB VRAM) is the Intel Arc B570 (10 GB).
Install Ollama then run: ollama run hf.co/1bitLLM/bitnet_b1_58-3B
Minimum VRAM: 3 GB. For best results use Q4_K_M quantization.
BitNet b1.58 needs about 3 GB VRAM at 1.58-bit quantization for its smallest variant. Variants: BitNet b1.58 3B (3 GB, 1.58-bit). On Apple Silicon, unified memory counts toward this requirement.
Yes — BitNet b1.58 runs on an RTX 4090 (24 GB) and other 24 GB cards such as the RTX 3090. Smaller variants also fit comfortably on 8–16 GB GPUs at 1.58-bit.
Q4_K_M is the best balance of quality and VRAM for BitNet b1.58 in most cases. Choose Q8_0 for near-lossless quality if you have spare VRAM, or smaller quants (Q3/Q2) only when memory is tight.
Install Ollama, then run: ollama run hf.co/1bitLLM/bitnet_b1_58-3B. This downloads BitNet b1.58 and starts a local, OpenAI-compatible endpoint — no internet connection is needed after the initial download.
