ToolsThe story, in brief
Deploying a 1-Bit Bonsai-27B Model with PrismML llama.cpp and OpenAI-Compatible Local Inference Workflows
1-bit quantization just went mainstream. Deploy 27B models locally with PrismML's CUDA-optimized llama.cpp fork.
The KeyNews take
Why it matters
Open-source quantization techniques are enabling on-device inference at scale, reducing cloud dependency and inference costs for developers building with large models.
