# Nexus-Flash-9B

This model is a fine-tuned version of **unsloth/Qwen3.5-9B**, optimized for agent-based reasoning tasks. It was trained using the [Unsloth](https://github.com/unslothai/unsloth) framework to achieve faster training speeds and memory efficiency.

## 📋 Model Details

- **Developed by:** ethanzxv
- **Base Model:** [unsloth/Qwen3.5-9B](https://huggingface.co/unsloth/Qwen3.5-9B)
- **License:** Apache-2.0
- **Language:** English
- **Finetuning Dataset:** [lambda/hermes-agent-reasoning-traces](https://huggingface.co/datasets/lambda/hermes-agent-reasoning-traces)

## 🚀 Training & Optimization

This model was trained **2x faster** using [Unsloth](https://github.com/unslothai/unsloth) combined with Hugging Face's TRL library. Unsloth allows for efficient fine-tuning of Large Language Models (LLMs) with significantly reduced VRAM usage and increased throughput.

### Dataset Information
The model was fine-tuned on the **Hermes Agent Reasoning Traces** dataset. This dataset focuses on enhancing the model's ability to perform complex reasoning steps, particularly in agentic workflows, by providing detailed traces of thought processes and decision-making paths.

- **Dataset:** [lambda/hermes-agent-reasoning-traces](https://huggingface.co/datasets/lambda/hermes-agent-reasoning-traces)

## 🎯 Intended Use & Capabilities

This model is designed for:
- **Agent Reasoning:** Improved performance in tasks requiring multi-step logical deduction.
- **Complex Problem Solving:** Better handling of intricate queries that require chain-of-thought processing.
- **General Text Generation:** Maintains the strong general capabilities of the base Qwen3.5-9B model.
