***This is a newer version of [VisualPRM-8B](https://huggingface.co/OpenGVLab/VisualPRM-8B), which exhibits superior performance compared to [VisualPRM-8B](https://huggingface.co/OpenGVLab/VisualPRM-8B).***

## Introduction
|
| 31 |
+
|
| 32 |
+
We introduce VisualPRM, an advanced multimodal Process Reward Model (PRM) with 8B parameters, which improves the reasoning abilities of existing Multimodal Large Language Models (MLLMs) across different model scales and families with Best-of-N (BoN) evaluation strategies. **Specifically, our model improves the reasoning performance of three types of MLLMs and four different model scales. Even when applied to the highly capable InternVL2.5-78B, it achieves a 5.9-point improvement across seven multimodal reasoning benchmarks.** Experimental results show that our model exhibits superior performance compared to Outcome Reward Models and Self-Consistency during BoN evaluation. To facilitate the training of multimodal PRMs, we construct a multimodal process supervision dataset VisualPRM400K using an automated data pipeline. For the evaluation of multimodal PRMs, we propose VisualProcessBench, a benchmark with human-annotated step-wise correctness labels, to measure the abilities of PRMs to detect erroneous steps in multimodal reasoning tasks. We hope that our work can inspire more future research and contribute to the development of MLLMs.

To find the measure of \\angle 3, we need to use the properties of the angles in the given geometric figure.
|
| 140 |
+
|
| 141 |
+
1. \\angle EDC is a right angle, and it is split into \\angle EDF and \\angle 3.
|
| 142 |
+
|
| 143 |
+
2. We know that \\angle EDF = 39^\\circ because it is labeled in the diagram.
|
| 144 |
+
|
| 145 |
+
3. Since \\angle EDC is 90^\\circ, we can set up the equation for \\angle 3: \\angle EDC = \\angle EDF + \\angle 3
|
| 146 |
+
|
| 147 |
+
4. Substituting the known values, we get: 90^\\circ = 39^\\circ + \\angle 3
|
| 148 |
+
|
| 149 |
+
5. Solving for \\angle 3: \\angle 3 = 90^\\circ - 39^\\circ
|
| 150 |
+
|
| 151 |
+
6. Simplifying the equation: \\angle 3 = 51^\\circ

Final answer: 51^\\circ

To find \\( m \\angle 3 \\), we need to analyze the given geometric figure carefully.
|
| 158 |
+
|
| 159 |
+
1. Recognize that \\( \\angle 3 \\) is part of triangle \\( BCE \\). Since \\( \\angle 1 \\) is given as 48° and \\( \\angle 2 \\) is a right angle (90°), we can use the properties of a right triangle to find \\( \\angle 3 \\).
|
| 160 |
+
|
| 161 |
+
2. The sum of the angles in any triangle is 180°. Therefore, in triangle \\( BCE \\): \[ \\angle 1 + \\angle 2 + \\angle 3 = 180° \]
|
| 162 |
+
|
| 163 |
+
3. Substitute the known values: \[ 48° + 90° + \\angle 3 = 180° \]
|
| 164 |
+
|
| 165 |
+
4. Solve for \\( \\angle 3 \\): \[ \\angle 3 = 180° - 48° - 90° = 42° \]
|
| 166 |
+
|
| 167 |
+
Thus, the measure of \\( \\angle 3 \\) is 42°.

r"""
|
| 18 |

This is the configuration class to store the configuration of a [`InternVisionModel`]. It is used to
|
| 19 |
+
instantiate a vision encoder according to the specified arguments, defining the model architecture.
|
| 20 |
+
|
| 21 |
+
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
| 22 |
+
documentation from [`PretrainedConfig`] for more information.
