About

Ternary Bonsai 27B is PrismML's prior-generation ternary 27B open-weight multimodal model from the 2026-07-14 Bonsai 27B launch (MCP-verified @PrismML 2077084891284721827 + first-party news/blog). Based on Qwen3.6 27B (live catalog slug qwen3.6-27b). Announce: ~5.9 GB footprint, laptop-class ternary variant alongside 1-bit Bonsai 27B (~3.9 GB phone-class — NOT seeded as separate model this pass; HOLD for EIC if desired). Apache 2.0; weights on HF prism-ml/Ternary-Bonsai-27B-gguf (+ mlx-2bit). Tip Bonsai 2 is the follow-up ~2 months later under the same Bonsai family. INSERT sibling under family bonsai (live /model/bonsai-27b and /model/ternary-bonsai-27b both 404). Compare it for Open Source / Multimodal / on-device.
