            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForImageTextToText

processor = AutoProcessor.from_pretrained("zss01/BiPS")
model = AutoModelForImageTextToText.from_pretrained("zss01/BiPS")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

# BiPS — Bi-directional Perceptual Shaping for Multimodal Reasoning

This model card describes **BiPS (Bi-directional Perceptual Shaping)**, a **training-time** framework proposed in *“See Less, See Right: Bi-directional Perceptual Shaping For Multimodal Reasoning”* [CVPR 2026].

- Paper: https://arxiv.org/abs/2512.22120
- Code: https://github.com/zss02/BiPS

## What is BiPS?

Many VLMs fail on multimodal reasoning because they **look at the wrong visual evidence** (especially for charts, thin lines, intersections, and small regions). BiPS improves **question-conditioned visual grounding** by turning “where-to-look” supervision into training signals—**without requiring extra tools at inference time**.

## Key idea

BiPS trains a VLM with two complementary view transformations:

- **Evidence-Preserving View**: keep only the visual evidence needed to answer, reduce distractions.
→ enforce **consistency** between predictions from the original image and the preserved view.

- **Evidence-Ablated View**: remove the key evidence so the image no longer supports the answer.
→ enforce **separation** so the model cannot rely on shortcuts.

These constraints are typically implemented with **KL-based objectives** and can be integrated into **GRPO** training.

## Why it matters

- Better **fine-grained evidence alignment**
- Less “guessing” from language priors
- **No additional inference overhead** (views are used only during training)

## How to use

BiPS is mainly a **training recipe**. To apply it:
1. Follow the official repo to set up dependencies and scripts.
2. Train your base VLM with BiPS-generated **preserve/ablate** views.
3. Use the resulting checkpoint as a standard VLM at inference time (no extra steps).
