⚙️ Features Overview

This version of the application uses state-of-the-art technology to improve speed and accuracy on compatible hardware:

• Large Context Support: Handles up to 256,000 tokens at once using FP8 key-value cache.

• NVFP4 Quantization: Compresses model data efficiently to run faster on your RTX 5090 without losing accuracy.

• Optimized on vLLM: Uses vLLM to manage model loading and execution for smooth responses.

• Responsive Text Generation: Generates text at about 200 tokens per second, allowing real-time interaction.

• Custom Chat Template: Supports a chat mode tuned for natural and consistent conversations.

• Single GPU Use: Runs efficiently on one NVIDIA RTX 5090, without needing multiple cards.

🛠 How It Works

The software uses the Qwen3.5-35B-A3B language model, which employs a mixture of experts (MoE) design. This means it activates only 3 billion parameters at a time out of 35 billion total, saving processing power.

The model is quantized using NVFP4, a special format that reduces memory use on NVIDIA GPUs, particularly the RTX 5090. It allows the software to handle huge amounts of text context efficiently.

vLLM manages the model's data and execution, organizing tasks so the GPU runs at peak performance. This setup delivers a balance between fast response times and high-quality output.

📝 Using the App

• Start by entering a query or prompt in the input box.

• Use the “Settings” menu to adjust options like context length (e.g., 4K, 8K, or full 256K tokens).

• Click “Generate” to have the AI process the prompt.

• Review the generated text in the results area.

• For chat use, access the chat interface template that allows continuous conversation with the model.

• Save output text if needed using the provided option.

The UI is designed for ease of use without programming knowledge.
