Bonsai 2 adds 2B, 4B and 9B models for everyday devices

PrismML says it released three Qwen3.5-based Bonsai 2 ternary models on October 15, 2026: the 2B is 0.43GB, the 4B is 0.95GB and the 9B is 2.0GB. The company designed them for local assistants on personal computers, phones and wearables. It says the 9B uses roughly 40% fewer tokens on standard instruction-following and everyday math tasks.
