Ornith-1.0-35B — APEX GGUF

APEX (Adaptive Precision for EXpert Models) quantizations of deepreinforce-ai/Ornith-1.0-35B — the lightweight, single-GPU member of the Ornith-1.0 self-improving family of open-source agentic-coding models (Qwen3.5 MoE base).

What is APEX?

APEX is a quantization strategy for Mixture-of-Experts (MoE) models. It classifies tensors by role (routed expert, shared expert, attention) and applies a layer-wise precision gradient — edge layers (first/last 5) get higher precision, middle layers get more aggressive compression. I-variants use diverse imatrix calibration (chat, code, reasoning, tool-calling, agentic traces, Wikipedia).

The key insight: in MoE models, expert FFN tensors make up the bulk of model weight but only ~8/256 experts activate per token. APEX compresses middle-layer experts more aggressively while preserving edge layers and keeping attention, SSM/Mamba, and shared-expert tensors at higher precision.

See the APEX project for full details, technical report, and scripts.
