## Introduction
Eagle 2.5 is a family of frontier vision-language models (VLMs) designed for long-context multimodal learning. While most existing VLMs focus on short-context tasks, Eagle 2.5 addresses the challenges of long video comprehension and high-resolution image understanding, providing a generalist framework for both. The Eagle 2.5 training framework introduces two key techniques—Automatic Degrade Sampling (ADS) and Image Area Preservation (IAP)—to preserve contextual integrity and visual details. Additionally, the training pipeline is optimized for efficient long-context data training.
A major contribution of Eagle 2.5 is the introduction of Eagle-Video-110K, a novel dataset with both story-level and clip-level annotations, specifically curated for long video understanding. Eagle 2.5 demonstrates substantial improvements on long-context multimodal benchmarks, offering a robust solution to the limitations of existing VLMs. Notably, Eagle 2.5-8B achieves 72.4% on Video-MME with 512 input frames, matching the results of top-tier commercial models such as GPT-4o and large-scale open-source models like Qwen2.5-VL-72B and InternVL2.5-78B, despite having significantly fewer parameters.
### Key Innovations
- **Information-First Sampling**:
- *Image Area Preservation (IAP)*: Optimizes image tiling to retain most of the original image area and aspect ratio, preserving fine-grained details.
- *Automatic Degrade Sampling (ADS)*: Dynamically balances visual and textual input, ensuring complete text retention while maximizing visual content within context length constraints.
- **Progressive Mixed Post-Training**:
- Gradually increases context length during training, enhancing the model's ability to process varying input sizes and improving information density over static sampling.
- **Diversity-Driven Data Recipe**:
- Combines open-source data (human-annotated and synthetic) with the self-curated Eagle-Video-110K dataset, collected via a diversity-driven strategy and annotated with both story-level and clip-level QA pairs.

## Stremlit Demo
We provide a [local chat demo](./Eagle2/streamlit_demo/README.md) powered by `Streamlit` to help users get started with `Eagle2` quickly and easily.
This demo is built upon [InternVL's template](https://internvl.readthedocs.io/en/latest/get_started/local_chat_demo.html) and extends it with additional video input support for enhanced functionality.
## Inference
We provide a [inference script](./Eagle2/inference/README.md) to help you quickly start using the model. We support different input types:
- pure text input
- single image input
- multiple image input
- video input

### 2. Prepare the Prompt
- Single image input
```python
prompt = [
{'role': 'system', 'content': 'You are a helpful assistant.'},
{'role': 'user', 'content': 'Describe this image in details.',
'image':[
{'url': 'https://www.nvidia.com/content/dam/en-zz/Solutions/about-nvidia/logo-and-brand/[email protected]'}
],
}
]
```
- Multiple image input
```python
prompt = [
{'role': 'system', 'content': 'You are a helpful assistant.'},
{'role': 'user', 'content': 'Describe these two images in details.',
'image':[
{'url': 'https://www.nvidia.com/content/dam/en-zz/Solutions/about-nvidia/logo-and-brand/[email protected]'},
{'url': 'https://www.nvidia.com/content/dam/en-zz/Solutions/about-nvidia/logo-and-brand/[email protected]'}
],
}
]
```
- Video input
```python
prompt = [
{'role': 'system', 'content': 'You are a helpful assistant.'},
{'role': 'user', 'content': 'Describe this video in details.',
'video':[
'path/to/your/video.mp4'
],
}
]
```
### 3. Generate the response
```python
params = {
'prompt': prompt,
'max_input_tiles': 24,
'temperature': 0.7,
'top_p': 1.0,
'max_new_tokens': 4096,
'repetition_penalty': 1.0,
}
worker.generate(params)
```
## Evaluation
We evaluate the performance of `Eagle2` based on [VLMEvalKit](https://github.com/open-compass/VLMEvalKit). We temporarily provide a custom [vlmeval](./Eagle2/vlmeval/README.md) implementation that supports `Eagle2` in our repo, and we will support `Eagle2` in the official version as soon as possible.
## TODO
- [ ] Support vLLM Inference
- [ ] Provide AWQ Quantization Weights
- [ ] Provide fine-tuning scripts
