 ## 🤝 Hybrid Architecture: Pairing Sparse-AST with Local Pretrained LLMs (via Ollama)
 
-While large general-purpose coding models (such as `Qwen2.5-Coder` or `DeepSeek-Coder`) excel at high-level reasoning and broad Python syntax, they frequently hallucinate deprecated Blender API operators (e.g. using 2.79 syntax in Blender 4.x/5.x) or struggle with precise vector trigonometry and procedural BMesh topologies.
+While general-purpose code LLMs (such as `Qwen2.5-Coder:3B` or `7B`) excel at high-level reasoning and natural language prompt decomposition, compact models frequently hallucinate deprecated Blender API operators (e.g. 2.79 syntax in Blender 4.x/5.x), output syntax fragments, or struggle with complex 3D vector rotation matrices (`mathutils.Euler`, quaternions, and SLERP).

+By pairing a **local LLM via Ollama** (specifically **`qwen2.5-coder:3b`**) with the **Sparse-AST / BWM model family & AST Guardrail Engine**, you create an ultra-low-latency, zero-leak **Local 3D Copilot**:
