| # TBAC-VLR1-3B |
|
|
| ## Overview |
| This is a multimodal language model fine-tuned by **Tencent PCG Basic Algorithm Center**. Based on Qwen2.5-VL-3B-Instruct, TBAC-VLR1-3B-SFT undergoes SFT |
| training using 40k sft data filtered from OpenR1-Math-220k. TBAC-VLR1-3B then employs GRPO (Group Relative Policy Optimization) and adapts Clip-Higher from DAPO, |
| achieving **state-of-the-art** results on several multimodal reasoning benchmarks among models of the same size. |

| ## Usage |
| ```python |
| from transformers import Qwen2_5_VLForConditionalGeneration, AutoTokenizer, AutoProcessor |
| from qwen_vl_utils import process_vision_info |
| |
| model = Qwen2_5_VLForConditionalGeneration.from_pretrained( |
| "TencentBAC/TBAC-VLR1-3B", torch_dtype="auto", device_map="auto" |
| ) |
| |
| processor = AutoProcessor.from_pretrained("TencentBAC/TBAC-VLR1-3B") |
| |
| messages = [ |
| { |
| "role": "system", |
| "content": "You FIRST think about the reasoning process as an internal monologue and then provide the final answer. The reasoning process MUST BE enclosed within <think> </think> tags. The final answer MUST BE put in \\boxed{}." |
| }, |
| { |
| "role": "user", |
| "content": [ |
| { |
| "type": "image", |
| "image": image_path, |
| }, |
| {"type": "text", "text": query}, |
| ], |
| } |
| ] |
| |
| # Preparation 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: Generation of the output |
| generated_ids = model.generate(**inputs, max_new_tokens=128, do_sample=False) |
| 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) |
