UIGEN-T3-14B-Preview: Advanced UI Generation with Hybrid Reasoning

Tesslate's UIGEN-T3-14B-Preview is a 14 billion parameter model leveraging the Qwen3 architecture, specifically engineered for generating user interfaces. This model can produce both individual UI components and complete web pages, including full <html> and <head> structures. A core differentiator is its hybrid reasoning system, which allows users to switch between /think mode for guided reasoning with layout analysis and heuristics, or /no_think mode for faster, direct code generation. Outputs also incorporate design tokens for easier site-wide customization.

Key Capabilities & Features

UI Generation: Creates clean HTML and CSS for components and full web pages.
Hybrid Reasoning: Offers controlled reasoning modes (/think for guided, /no_think for raw code).
Design Tokens: Includes design token headers for customizable outputs.
Evaluation Framework: Developed using UIGenEval, an internal benchmark assessing technical quality, prompt adherence, interaction behavior, and responsive design.
Context Length: Supports up to 32768 tokens, with 20k recommended for optimal reasoning performance.

Good For

Startup MVPs: Rapidly scaffolding UIs from scratch.
Component Libraries: Generating buttons, cards, and navigation elements at scale.
Internal Tool Builders: Creating admin panels, dashboards, and layout templates.
Rapid Client Prototypes: Producing production-ready HTML+Tailwind mockups quickly.

Limitations

Currently, the model does not support Bootstrap and is intended for research and non-commercial use only. Responsive tuning may vary with output complexity.
