Roblox_Coder is a fine-tuned version of Qwen 3.5 4B, trained specifically for Roblox Studio development and Luau programming.
It is designed to act as a Roblox backend + systems development assistant, capable of generating structured, server-authoritative, and production-style Luau code for real Roblox game development workflows.
The model was trained on a curated instruction dataset focused on high-quality Roblox systems design, covering backend architecture, secure scripting patterns, and scalable game development workflows.
- Server-authoritative game architecture
- DataStore systems and persistence
- RemoteEvent / RemoteFunction networking
- Secure combat and anti-exploit patterns
- NPC AI and Pathfinding systems
- Inventory, shop, and progression systems
- UI frameworks and Roblox client systems
- Performance-aware Luau scripting patterns
This model is optimized for Roblox systems engineering, and performs best in backend-heavy development tasks.
- Generates structured Luau systems (services, modules, frameworks)
- Strong understanding of client-server separation
- Produces secure server-authoritative gameplay logic
- Implements DataStore-backed progression systems
- Builds scalable inventory, shop, and economy systems
- Designs NPC AI with PathfindingService
- Handles RemoteEvent validation and anti-exploit logic
- Creates modular Roblox architecture patterns (Service-based design)
- Enforces anti-exploit security by default in generated code
- Prefers scalable architecture over quick scripts
- Uses strict typing patterns where applicable (
--!strict) - Encourages server-side validation for all critical logic
- Produces production-style Luau structure rather than beginner scripts
- Not optimized for animation, VFX, or art-heavy systems
- Limited knowledge of Studio UI/UX design workflows
- May over-engineer simple tasks into full systems
- Lower dataset size limits general Roblox coverage
This model can run locally in GGUF or quantized formats.
