Model overview
Prism ML's ternary `Ternary-Bonsai-2-27B` build of `Qwen/Qwen3.8-27B`, repacked for chad, a Claude-Code-style local coding agent for Apple Silicon, **with its speculative decoder bundled in**. This is chad's default model. Created using Bonsai by Prism ML. One download gets both halves: the ternary target model and the block drafter it decodes with, already quantized. Nothing is built on first run. Every projection of Qwen3.8-27B (a dense `qwen3_5` hybrid: 64 layers, 48 GatedDeltaNet + 16 full attention) is stored in a **Hadamard-rotated basis**: multiplied by a fixed sign vector and put through a blockwise Walsh-Hadamard transform offline, then quantized to 2-bit affine group-128 whose three levels reproduce the ternary set {−s, 0, +s}. The rotation costs no extra bits and no extra weight traffic, but the matching transform must be applied to the activations at runtime and inverted after the embedding lookup. **An ordinary MLX affine loader finds tensors of exactly the right shapes, skips both transforms, and produces plausible garbage without raising.** chad routes the pack on its `model_type` (`prism_hadamard_qwen35`) to a loader that does the rotation; mlx-lm alone will not run it correctly.

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
