# **JSONify-Flux-Large**
|
|
|
|
The **JSONify-Flux-Large** model is a fine-tuned version of **Qwen2VL**, specifically trained on **Flux-generated images** and their **corresponding captions**. This model has been trained using a **30M trainable parameter** dataset and is designed to output responses in structured **JSON format** while maintaining state-of-the-art performance in **Optical Character Recognition (OCR)**, **image-to-text conversion**, and **math problem-solving with LaTeX formatting**.
|
|
|
|
### Key Enhancements:
|
|
|
|
* **Optimized for Flux-Generated Image Captioning**: JSONify-Flux-Large has been trained to understand and describe images created using Flux-based generation techniques.
|
|
|
|
* **State-of-the-Art Image Understanding**: Built on Qwen2VL's architecture, JSONify-Flux-Large excels in visual reasoning tasks like DocVQA, RealWorldQA, MTVQA, and more.
|
|
|
|
* **Formatted JSON Output**: Responses are structured in a JSON format, making it ideal for automation, database storage, and further processing.
|
|
|
|
* **Multilingual Support**: Recognizes and extracts text from images in multiple languages, including English, Chinese, Japanese, Arabic, and various European languages.
|
|
|
|
* **Supports Multi-Turn Interactions**: Maintains context in conversations and can provide extended reasoning over multiple inputs.

### How to Use
|
|
|
|
```python
|
|
from transformers import Qwen2VLForConditionalGeneration, AutoTokenizer, AutoProcessor
|
|
from qwen_vl_utils import process_vision_info
|
|
|
|
# Load the model on the available device(s)
|
|
model = Qwen2VLForConditionalGeneration.from_pretrained(
|
|
"prithivMLmods/JSONify-Flux-Large", torch_dtype="auto", device_map="auto"
|
|
)
|
|
|
|
# Enable flash_attention_2 for better acceleration and memory efficiency
|
|
# model = Qwen2VLForConditionalGeneration.from_pretrained(
|
|
# "prithivMLmods/JSONify-Flux-Large",
|
|
# torch_dtype=torch.bfloat16,
|
|
# attn_implementation="flash_attention_2",
|
|
# device_map="auto",
|
|
# )
|
|
|
|
# Default processor
|
|
processor = AutoProcessor.from_pretrained("prithivMLmods/JSONify-Flux-Large")
|
|
|
|
messages = [
|
|
{
|
|
"role": "user",
|
|
"content": [
|
|
{
|
|
"type": "image",
|
|
"image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg",
|
|
},
|
|
{"type": "text", "text": "Describe this image in JSON format."},
|
|
],
|
|
}
|
|
]
|
|
|
|
# Prepare inputs for inference
|
|
text = processor.apply_chat_template(
|
|
messages, tokenize=False, add_generation_prompt=True
|
|
)
|
|
image_inputs, video_inputs = process_vision_info(messages)
|
|
inputs = processor(
|
|
text=[text],
|
|
images=image_inputs,
|
|
videos=video_inputs,
|
|
padding=True,
|
|
return_tensors="pt",
|
|
)
|
|
inputs = inputs.to("cuda")
|
|
|
|
# Inference: Generate JSON-formatted output
|
|
generated_ids = model.generate(**inputs, max_new_tokens=128)
|
|
generated_ids_trimmed = [
|
|
out_ids[len(in_ids) :] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
|
|
]
|
|
output_text = processor.batch_decode(
|
|
generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
|
|
)
|
|
|
|
print(output_text) # JSON-formatted response
|
|
```
|
|
|
|
### JSON Buffer Handling
|
|
```python
|
|
buffer = ""
|
|
for new_text in streamer:
|
|
buffer += new_text
|
|
buffer = buffer.replace("<|im_end|>", "")
|
|
yield buffer
|
|
```
|
|
|
|
