AndesVL is a suite of mobile-optimized Multimodal Large Language Models (MLLMs) with **0.6B to 4B parameters**, built upon Qwen3's LLM and various visual encoders. Designed for efficient edge deployment, it achieves first-tier performance on diverse benchmarks, including those for text-rich tasks, reasoning tasks, Visual Question Answering (VQA), multi-image tasks, multilingual tasks, and GUI tasks. Its "1+N" LoRA architecture and QALFT framework facilitate efficient task adaptation and model compression, enabling a 6.7x peak decoding speedup and a 1.8 bits-per-weight compression ratio on mobile chips.

Detailed model sizes and components are provided below:

| Model | Total Parameters (B) | Visual Encoder | LLM |
|---|---|---|---|
| **AndesVL-0.6B** | 0.695 | SigLIP2-Base | Qwen3-0.6B |
| AndesVL-1B | 0.927 | AIMv2-Large | Qwen3-0.6B |
| AndesVL-2B | 2.055 | AIMv2-Large | Qwen3-1.7B|
| AndesVL-4B | 4.360 | AIMv2-Large | Qwen3-4B |


# Quick Start
```commandline
# require transformers>=4.52.4

import torch
from transformers import AutoModel, AutoTokenizer, CLIPImageProcessor

model_dir = "OPPOer/AndesVL-0_6B-Instruct"

model = AutoModel.from_pretrained(model_dir, trust_remote_code=True,torch_dtype=torch.bfloat16).cuda()
tokenizer = AutoTokenizer.from_pretrained(model_dir, trust_remote_code=True)
image_processor = CLIPImageProcessor.from_pretrained(model_dir, trust_remote_code=True)

messages = [
                {
                    "role": "user",
                    "content": [
                        {"type": "text", "text": "描述这张图片。"},
                        {
                            "type": "image_url",
                            "image_url": {

                            },
                        }
                    ],
                },
        ]
res = model.chat(messages, tokenizer, image_processor, max_new_tokens=1024, do_sample=True, temperature=0.6)
