# QwenStoryteller

This HF Space is a simple implementation of [2505.10292](https://arxiv.org/abs/2505.10292) by Daniel A. P. Oliveira and David Martins de Matos. BibTeX citation provided below. The space was created as a POC, all other credits go to Daniel and David.

QwenStoryteller is a fine-tuned version of Qwen2.5-VL 7B specialized for grounded visual storytelling with cross-frame consistency, capable of generating coherent narratives from multiple images while maintaining character and object identity throughout the story.

## Model Description

**Base Model:** Qwen2.5-VL 7B  
**Training Method:** LoRA fine-tuning (rank 2048, alpha 4096)  
**Training Dataset:** [StoryReasoning](https://huggingface.co/datasets/daniel3303/StoryReasoning)

QwenStoryteller processes sequences of images to perform:
- End-to-end object detection
- Cross-frame object re-identification
- Landmark detection
- Chain-of-thought reasoning for scene understanding
- Grounded story generation with explicit visual references

The model was fine-tuned on the StoryReasoning dataset using LoRA with a rank of 2048 and alpha scaling factor of 4096, targeting self-attention layers of the language components. Training used a peak learning rate of 1×10⁻⁴ with batch size 32, warmup for the first 3% of steps for 4 epochs, AdamW optimizer with weight decay 0.01, and bfloat16 precision.

## System Prompt
The model was trained with the following system prompt, and we recommend using it as it is for inference.

```
You are an AI storyteller that can analyze sequences of images and create creative narratives. 
First think step-by-step to analyze characters, objects, settings, and narrative structure. 
Then create a grounded story that maintains consistent character identity and object references across frames. 
Use <think></think> tags to show your reasoning process before writing the final story.
```

## Key Features

- **Cross-Frame Consistency:** Maintains consistent character and object identity across multiple frames through visual similarity and face recognition techniques
- **Structured Reasoning:** Employs chain-of-thought reasoning to analyze scenes with explicit modeling of characters, objects, settings, and narrative structure
- **Grounded Storytelling:** Uses specialized XML tags to link narrative elements directly to visual entities
- **Reduced Hallucinations:** Achieves 12.3% fewer hallucinations compared to the non-fine-tuned base model
