PrismML releases Bonsai 27B, a 27B LLM for offline mobile use

By PulseAugur Editorial · [1 sources] ·

PrismML has released Bonsai 27B, a 27-billion-parameter large language model capable of running offline on mobile devices like the iPhone 17 Pro Max. The model achieves its small footprint through a novel 1-bit training approach rather than traditional quantization, resulting in a 3.9GB file size. While it maintains strong reasoning and code generation capabilities, it shows degradation in agentic tasks like tool-calling. Bonsai 27B can be accessed via WebGPU in a browser or integrated with OpenAI-compatible clients. AI

IMPACT Enables more powerful AI applications to run directly on mobile devices, enhancing privacy and reducing reliance on cloud infrastructure.
