Known issues we've tracked

LAUNCH (2026-07-14): PrismML released Bonsai 27B -- 'the first 27B-class model to run on a phone.' Two builds of Qwen3.6 27B: **ternary** (5.9GB, 1.71 effective bits/weight, retains ~95% of baseline -- 80.5 vs 85.0 aggregate across 15 math/coding/tool-calling/knowledge/vision/instruction benchmarks) and **1-bit** (3.9GB, 1.125 bits/weight, ~90% retention, 76.1 aggregate). Multimodal via a compact 4-bit vision tower; 262K context; DSpark speculative drafter; multi-step reasoning, structured tool calls, and computer-use loops preserved. Runs natively on Apple devices via MLX and NVIDIA via CUDA; ships in the 'Locally AI' iOS app; free limited-time developer API plus Together.ai hosting. Apache 2.0.
