Jagle-VL-2.2B-Jagle is a 2.2B vision language model trained on Jagle dataset.

Model Architecture

The model architecture is inspired by InternVL3.0 and consists of a language model, a vision encoder, and a lightweight projector.

• LLM: Qwen/Qwen3-1.7B (1.7B)
• Vision Encoder: google/siglip2-so400m-patch16-512 (0.4B)
• Projector: 2-layer MLP

Training Data

This model is trained on Jagle dataset.

Usage

Install requirements.

uv add "torch==2.8.0" "transformers==4.57.0" "flash-attn==2.8.3" "pillow==11.3.0"

Below is the sample code to run the model.

import torch
from transformers import AutoProcessor, AutoModel

model_id = "llm-jp/Jagle-VL-2.2B-Jagle"

# load model
model = (
    AutoModel.from_pretrained(
        model_id,
        torch_dtype=torch.bfloat16,
        trust_remote_code=True,
        use_flash_attn=True,
    )
    .eval()
    .cuda()
)

processor = AutoProcessor.from_pretrained(model_id, trust_remote_code=True)


def generate(messages, max_new_tokens=256, temperature=0.0):
    inputs = processor.apply_chat_template(
        messages,
        tokenize=True,
        add_generation_prompt=True,
        return_dict=True,
        return_tensors="pt",
    ).to(model.device)

    if "pixel_values" in inputs:
        inputs["pixel_values"] = inputs["pixel_values"].to(dtype=model.dtype)

    outputs = model.generate(
        **inputs,
        max_new_tokens=max_new_tokens,
        do_sample=temperature > 0,
        temperature=temperature if temperature > 0 else None,
    )

    text = processor.decode(outputs[0], skip_special_tokens=False)
    text = text.replace("<|channel|>final<|message|>", "")
    text = text.replace("<|return|>", "")
    text = text.replace(processor.tokenizer.eos_token, "")
    return text.strip()
