Overview

anshulVashist/Qwen3-8B-Houdini-VEX-v11, also known as the "Grandmaster Edition," is an 8 billion parameter neural code intelligence model developed by Anshul Vashist. It is specifically fine-tuned for generating SideFX Houdini VEX code, built upon the Qwen3-8B architecture. This model is distinguished by its rigorous Compiler-in-the-Loop (CITL) Verification, ensuring generated code is syntactically correct and avoids common errors by auditing against SideFX's native vcc compiler.

Key Capabilities

  • Compiler-in-the-Loop (CITL) Verification: Ensures VEX code is free from syntax errors, deprecated functions, and signature hallucinations.
  • Dual-Mode Architectural Reasoning: Offers a "Turbo Mode" for direct, compile-ready VEX snippets without conversational filler, and a "Deep Reasoning Mode" that performs explicit architectural analysis (e.g., 3D vector trigonometry, spatial hash lookups) before generating code.
  • Rigorous 3D Math Mastery: Handles complex quaternion and matrix mathematics, including p@orient = dihedral(...), qrotate, matrix3, and lookat transforms.
  • VDB & Volume Existence Guards: Incorporates automatic bounds checks, nametoprim guards, and volumetric gradient advection.
  • Negative Error Correction: Specifically fine-tuned to avoid common VEX pitfalls and legacy GLSL habits.

Good for

  • Houdini VEX Code Generation: Ideal for developers and artists needing to quickly generate accurate and complex VEX code for procedural graphics.
  • Automating Procedural Workflows: Can be integrated directly into Houdini via the ai_attribwrangle.hda digital asset for real-time viewport feedback.
  • Learning and Debugging VEX: Its deep reasoning capabilities can help in understanding the underlying logic of 3D procedural algorithms.
  • High-Precision VEX Tasks: Suitable for tasks requiring precise 3D rotations, volume manipulations, and attribute handling.
