Nero-800M

Nero-800M is a compact open-source language model based on Qwen3.5-0.8B, fine-tuned to improve instruction following, conversational ability, and reasoning behavior while maintaining fast and efficient inference.

Nero-800M is designed for users who want a capable AI assistant that can run locally on limited hardware.

Model Details

Training

Nero-800M was trained using parameter-efficient fine-tuning methods:

• Supervised Fine-Tuning (SFT)
• QLoRA
• LoRA refinement

Training focused on:

• Instruction following
• Helpful assistant behavior
• Response formatting
• Reasoning improvements

Intended Use

Nero-800M is suitable for:

• Local AI assistants
• Edge devices
• Lightweight chat applications
• AI experimentation
• Educational projects

Limitations

Due to its compact size, Nero-800M may:

• Have weaker reasoning than larger models
• Make factual mistakes
• Struggle with complex multi-step tasks

For more demanding workloads, larger Nero models are recommended.
