Ornith-1.0-9B · JANG_4M
Official OsaurusAI JANG_4M build of deepreinforce-ai/Ornith-1.0-9B (MIT) — a vision-language model on a Qwen3.5 hybrid backbone. Mixed-precision affine (JANG_4M); runs on Apple Silicon via Osaurus.
- ~6.3 GB (from ~18.8 GB bf16) bundle.
- JANG_4M: 8-bit affine attention + 4-bit affine MLP (mixed precision, group-size 64); embeddings/head per-module; vision tower kept fp16.
- Vision-language (image + text → text).

Running it
JANG bundles use the Qwen3.5 RMSNorm +1 scale_shift applied at runtime, so load them in Osaurus (or the vMLX runtime), which handles it automatically:
osaurus run OsaurusAI/Ornith-1.0-9B-JANG_4M
Note: a plain
mlx_lm.generatewill not be coherent on a JANG bundle — it omits the +1 norm shift. Use the Osaurus / vMLX runtime (orvmlx_engine.loaders.load_jang), which applies it.
