Instructions to use gaostar/DeViL-7B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use gaostar/DeViL-7B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="gaostar/DeViL-7B", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("gaostar/DeViL-7B", trust_remote_code=True, dtype="auto")

vLLM

How to use gaostar/DeViL-7B with vLLM:

Install from pip and serve model

# Install vLLM from pip:
pip install vllm
# Start the vLLM server:
vllm serve "gaostar/DeViL-7B"
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:8000/v1/chat/completions" \
	-H "Content-Type: application/json" \
	--data '{
		"model": "gaostar/DeViL-7B",
		"messages": [
			{
				"role": "user",
				"content": "What is the capital of France?"
			}
		]
	}'

Use Docker

docker model run hf.co/gaostar/DeViL-7B

SGLang

How to use gaostar/DeViL-7B with SGLang:

Install from pip and serve model

## Overview

DeViL is a detector-empowered video large language model designed for efficient spatio-temporal video grounding (STVG) and grounded video reasoning. Instead of relying on long autoregressive coordinate decoding or expensive candidate construction, DeViL offloads dense spatial grounding to a fully parallel detector. It distills the user query into a detector-compatible reference-semantic token and uses temporal consistency regularization to maintain object coherence across frames.

This repository hosts the official DeViL-7B checkpoint released by the authors.

## Highlights

- Detector-empowered grounding for efficient spatio-temporal localization
- Strong performance reported in the paper: 43.1 m_vIoU on HC-STVG and 14.33 FPS

- Preserves the backbone MLLM's general video understanding and reasoning ability

- Supports both image and video inputs in the official demo pipeline
