Our latest quantization method introduces precision-adaptive quantization for ultra-low-bit models (1-2 bit), with benchmark-proven improvements on Llama-3-8B. This approach uses layer-specific strategies to preserve accuracy while maintaining extreme memory efficiency.

Benchmark Context

All tests conducted on Llama-3-8B-Instruct using:

Standard perplexity evaluation pipeline
2048-token context window
Same prompt set across all quantizations

Method

Dynamic Precision Allocation:
- First/Last 25% of layers → IQ4_XS (selected layers)
- Middle 50% → IQ2_XXS/IQ3_S (increase efficiency)
Critical Component Protection:
- Embeddings/output layers use Q5_K
- Reduces error propagation by 38% vs standard 1-2bit

Quantization Performance Comparison (Llama-3-8B)

Quantization	Standard PPL	DynamicGate PPL	Δ PPL	Std Size	DG Size	Δ Size	Std Speed	DG Speed
IQ2_XXS	11.30	9.84	-12.9%	2.5G	2.6G	+0.1G	234s	246s
IQ2_XS	11.72	11.63	-0.8%	2.7G	2.8G	+0.1G	242s	246s
IQ2_S	14.31	9.02	-36.9%	2.7G	2.9G	+0.2G	238s	244s
IQ1_M	27.46	15.41	-43.9%	2.2G	2.5G	+0.3G	206s	212s
IQ1_S	53.07	32.00	-39.7%	2.1G	2.4G	+0.3G	184s	209s

Key:

PPL = Perplexity (lower is better)
Δ PPL = Percentage change from standard to DynamicGate
Speed = Inference time (CPU avx2, 2048 token context)
Size differences reflect mixed quantization overhead

Key Improvements:

🔥 IQ1_M shows massive 43.9% perplexity reduction (27.46 → 15.41)
🚀 IQ2_S cuts perplexity by 36.9% while adding only 0.2GB
⚡ IQ1_S maintains 39.7% better accuracy despite 1-bit quantization

Tradeoffs:

Inference speeds remain comparable (<5% difference)

When to Use These Models

📌 Fitting models into GPU VRAM

✔ Memory-constrained deployments

✔ Cpu and Edge Devices where 1-2bit errors can be tolerated

✔ Research into ultra-low-bit quantization

Choosing the Right Model Format

Selecting the correct model format depends on your hardware capabilities and memory constraints.

BF16 (Brain Float 16) – Use if BF16 acceleration is available

A 16-bit floating-point format designed for faster computation while retaining good precision.
Provides similar dynamic range as FP32 but with lower memory usage.
Recommended if your hardware supports BF16 acceleration (check your device's specs).
Ideal for high-performance inference with reduced memory footprint compared to FP32.

📌 Use BF16 if:
✔ Your hardware has native BF16 support (e.g., newer GPUs, TPUs).
✔ You want higher precision while saving memory.
✔ You plan to requantize the model into another format.

📌 Avoid BF16 if:
❌ Your hardware does not support BF16 (it may fall back to FP32 and run slower).
❌ You need compatibility with older devices that lack BF16 optimization.

F16 (Float 16) – More widely supported than BF16

A 16-bit floating-point high precision but with less of range of values than BF16.
Works on most devices with FP16 acceleration support (including many GPUs and some CPUs).
Slightly lower numerical precision than BF16 but generally sufficient for inference.

📌 Use F16 if:
✔ Your hardware supports FP16 but not BF16.
✔ You need a balance between speed, memory usage, and accuracy.
✔ You are running on a GPU or another device optimized for FP16 computations.

📌 Avoid F16 if:
❌ Your device lacks native FP16 support (it may run slower than expected).
❌ You have memory limitations.

Quantized Models (Q4_K, Q6_K, Q8, etc.) – For CPU & Low-VRAM Inference

Quantization reduces model size and memory usage while maintaining as much accuracy as possible.

Lower-bit models (Q4_K) → Best for minimal memory usage, may have lower precision.
Higher-bit models (Q6_K, Q8_0) → Better accuracy, requires more memory.

📌 Use Quantized Models if:
✔ You are running inference on a CPU and need an optimized model.
✔ Your device has low VRAM and cannot load full-precision models.
✔ You want to reduce memory footprint while keeping reasonable accuracy.

📌 Avoid Quantized Models if:
❌ You need maximum accuracy (full-precision models are better for this).
❌ Your hardware has enough VRAM for higher-precision formats (BF16/F16).

Very Low-Bit Quantization (IQ3_XS, IQ3_S, IQ3_M, Q4_K, Q4_0)

These models are optimized for extreme memory efficiency, making them ideal for low-power devices or large-scale deployments where memory is a critical constraint.

IQ3_XS: Ultra-low-bit quantization (3-bit) with extreme memory efficiency.
- Use case: Best for ultra-low-memory devices where even Q4_K is too large.
- Trade-off: Lower accuracy compared to higher-bit quantizations.
IQ3_S: Small block size for maximum memory efficiency.
- Use case: Best for low-memory devices where IQ3_XS is too aggressive.
IQ3_M: Medium block size for better accuracy than IQ3_S.
- Use case: Suitable for low-memory devices where IQ3_S is too limiting.
Q4_K: 4-bit quantization with block-wise optimization for better accuracy.
- Use case: Best for low-memory devices where Q6_K is too large.
Q4_0: Pure 4-bit quantization, optimized for ARM devices.
- Use case: Best for ARM-based devices or low-memory environments.

Summary Table: Model Format Selection

Model Format	Precision	Memory Usage	Device Requirements	Best Use Case
BF16	Highest	High	BF16-supported GPU/CPUs	High-speed inference with reduced memory
F16	High	High	FP16-supported devices	GPU inference when BF16 isn't available
Q4_K	Medium Low	Low	CPU or Low-VRAM devices	Best for memory-constrained environments
Q6_K	Medium	Moderate	CPU with more memory	Better accuracy while still being quantized
Q8_0	High	Moderate	CPU or GPU with enough VRAM	Best accuracy among quantized models
IQ3_XS	Very Low	Very Low	Ultra-low-memory devices	Extreme memory efficiency and low accuracy
Q4_0	Low	Low	ARM or low-memory devices	llama.cpp can optimize for ARM devices

Model Card for UIGEN-T2-7B

OUR Training Article

Testing Github for Artifacts

Model Overview

We're excited to introduce UIGEN-T2, the next evolution in our UI generation model series. Fine-tuned from the highly capable Qwen2.5-Coder-7B-Instruct base model using PEFT/LoRA, UIGEN-T2 is specifically designed to generate HTML and Tailwind CSS code for web interfaces. What sets UIGEN-T2 apart is its training on a massive 50,000 sample dataset (up from 400) and its unique UI-based reasoning capability, allowing it to generate not just code, but code informed by thoughtful design principles.

Model Highlights

High-Quality UI Code Generation: Produces functional and semantic HTML combined with utility-first Tailwind CSS.
Massive Training Dataset: Trained on 50,000 diverse UI examples, enabling broader component understanding and stylistic range.
Innovative UI-Based Reasoning: Incorporates detailed reasoning traces generated by a specialized "teacher" model, ensuring outputs consider usability, layout, and aesthetics. (See example reasoning in description below)
PEFT/LoRA Trained (Rank 128): Efficiently fine-tuned for UI generation. We've published LoRA checkpoints at each training step for transparency and community use!
Improved Chat Interaction: Streamlined prompt flow – no more need for the awkward double think prompt! Interaction feels more natural.

Example Reasoning (Internal Guide for Generation)

Here's a glimpse into the kind of reasoning that guides UIGEN-T2 internally, generated by our specialized teacher model:

plaintext

<|begin_of_thought|>
When approaching the challenge of crafting an elegant stopwatch UI, my first instinct is to dissect what truly makes such an interface delightful yet functional—hence, I consider both aesthetic appeal and usability grounded in established heuristics like Nielsen’s “aesthetic and minimalist design” alongside Gestalt principles... placing the large digital clock prominently aligns with Fitts’ Law... The glassmorphism effect here enhances visual separation... typography choices—the use of a monospace font family ("Fira Code" via Google Fonts) supports readability... iconography paired with labels inside buttons provides dual coding... Tailwind CSS v4 enables utility-driven consistency... critical reflection concerns responsiveness: flexbox layouts combined with relative sizing guarantee graceful adaptation...
<|end_of_thought|>

Example Outputs

Use Cases

Recommended Uses

Rapid UI Prototyping: Quickly generate HTML/Tailwind code snippets from descriptions or wireframes.
Component Generation: Create standard and custom UI components (buttons, cards, forms, layouts).
Frontend Development Assistance: Accelerate development by generating baseline component structures.
Design-to-Code Exploration: Bridge the gap between design concepts and initial code implementation.

Limitations

Current Framework Focus: Primarily generates HTML and Tailwind CSS. (Bootstrap support is planned!).
Complex JavaScript Logic: Focuses on structure and styling; dynamic behavior and complex state management typically require manual implementation.
Highly Specific Design Systems: May need further fine-tuning for strict adherence to unique, complex corporate design systems.
