TL;DR
1-bit Bonsai models achieve 8× speedup and 14× smaller footprint than full-precision alternatives while maintaining benchmark parity.
Key Points
- 1-bit Bonsai 8B: 1.15GB memory footprint, 8× faster inference, 5× more energy efficient than full-precision baseline
- 1-bit Bonsai 4B: 0.57GB memory, 132 tokens/second on M4 Pro, matches leading 8B model accuracy
- 1-bit Bonsai 1.7B: 0.24GB memory, 130 tokens/second on iPhone 17 Pro Max, optimized for on-device inference
- Maintains benchmark performance (IFEval, GSM8K, HumanEval+, BFCL, MuSR, MMLU-Redux) despite extreme quantization
Why It Matters
1-bit weight quantization enables deployment of capable LLMs on resource-constrained edge devices—phones, robots, IoT hardware—without significant accuracy loss. This opens real-time inference possibilities for applications previously requiring cloud compute, critical for latency-sensitive robotics and offline-first systems.
