Octans-Qwen3-UI-Code-4B

Octans-Qwen3-UI-Code-4B is an optimized successor of Muscae-Qwen3-UI-Code-4B, fine-tuned for enhanced UI reasoning precision, layout structuring, and frontend code synthesis. Built upon Qwen3-4B and refined through Abliterated Reasoning Optimization, it delivers balanced, structured, and production-grade UI code outputs for experimental and research use. Ideal for frontend developers, UI engineers, and design system researchers exploring next-generation code synthesis.

Key Features

Enhanced UI-Oriented Reasoning Upgraded reasoning calibration from Muscae with deeper token optimization for frontend logic, layout reasoning, and component cohesion.
Refined Web UI Component Generation Generates responsive, accessible, and semantic UI components with Tailwind, React, and HTML5, ensuring cleaner syntax and reduced redundancy.
Improved Layout-Aware Structure Demonstrates superior understanding of hierarchical design, stateful components, and responsive alignment, enhancing multi-device compatibility.
Optimized Hybrid Reasoning Engine Integrates symbolic and probabilistic logic for event-driven UI workflows, conditional rendering, and state synchronization in code outputs.
Structured Output Excellence Produces consistent results in HTML, React, Markdown, JSON, and YAML, suitable for UI prototyping, design systems, and auto-documentation.
Lightweight and Deployable Maintains a 4B parameter scale, optimized for mid-range GPUs, edge inference, or offline environments, without compromising structure or reasoning depth.

Quickstart with Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "prithivMLmods/Octans-Qwen3-UI-Code-4B"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "Generate a responsive dashboard layout with Tailwind and modular React components."

messages = [
    {"role": "system", "content": "You are a frontend coding assistant skilled in UI generation, semantic HTML, and structured React components."},
    {"role": "user", "content": prompt}
]

text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=512
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)

Intended Use

Advanced web UI and component code generation
Responsive frontend prototyping with Tailwind/React
Research on structured reasoning in code synthesis
Semantic, design-system-aligned component generation
Experimental projects exploring UI intelligence modeling

Limitations

Research-focused model – not fine-tuned for production-critical pipelines
Specialized for UI code – not suitable for general text generation or long-form reasoning
May exhibit variability with cross-framework or overextended prompts
Prioritizes code structure and logic clarity over aesthetic or creative expression.
