# Chitrarth: Bridging Vision and Language for a Billion People
[Paper Link👁️](https://arxiv.org/abs/2502.15392)
[](https://huggingface.co/krutrim-ai-labs/chitrarth) [](https://github.com/ola-krutrim/Chitrarth) [](https://cloud.olakrutrim.com/console/inference-service?section=models&modelName=Krutrim&artifactName=chitrarth&artifactType=model) [](https://ai-labs.olakrutrim.com/models/Chitrarth-1)
## 1. Introduction
Chitrarth (Chitra: Image; Artha: Meaning) is a multilingual VLM that integrates a state-of-the-art multilingual Large Language Model (LLM) with a vision module. This model is trained primarily on multilingual image-text data and is designed to work across 10 prominent Indian languages, including Hindi, Bengali, Telugu, Tamil, Marathi, Gujarati, Kannada, Malayalam, Odia, and Assamese, as well as English

## 2. Model Summary
### Key Features
- **Model:** Krutrim-1 as the base LLM, SigLIP as the visual encoder with 2 layer MLP
- **Languages Supported:** 10 Indic languages - Hindi, Bengali, Telugu, Tamil, Marathi, Gujarati, Kannada, Malayalam, Odia, and Assamese, as well as English
- **Usage:** General purpose VLM
## 3. API Platform
Visit [Chitrarth Online](https://cloud.olakrutrim.com/console/inference-service?section=models&modelName=Krutrim&artifactName=chitrarth&artifactType=model) to access the model via the web interface.
## 4. Inference code
```
git clone https://github.com/ola-krutrim/Chitrarth.git
conda create --name chitrarth python=3.10
conda activate chitrarth
cd Chitrarth
pip install -e .
python chitrarth/inference.py --model-path "krutrim-ai-labs/chitrarth" --image-file "assets/govt_school.jpeg" --query "Explain the image. "
```
## 5. Evaluation Results
Performance against SOTA VLMs on different academic multimodal tasks. Our model consistently outperforms IDEFICS 2 (7B) and PALO 7B on different benchmarks while remaining competitive on TextVQA and Vizwiz.
We introduce **BharatBench**, a comprehensive evaluation benchmark suite designed for **10 under-resourced Indic languages** across **3 tasks**. The performance of **Chitrarth** on the BharatBench Evaluation framework sets a strong baseline for future research in this domain. Our model is unique in its ability to handle all included languages.
Below are the performance results of **Chitrarth** on BharatBench across three evaluation tasks: **POPE**, **LLaVA-Bench**, and **MMVet**.
| **Language** | **POPE** | **LLaVA-Bench** | **MMVet** |
|----------------|----------|-----------------|-----------|
| **Telugu** | 79.9 | 54.8 | 43.76 |
| **Hindi** | 78.68 | 51.5 | 38.85 |
| **Bengali** | 83.24 | 53.7 | 33.24 |
| **Malayalam** | 85.29 | 55.5 | 25.36 |
| **Kannada** | 85.52 | 58.1 | 46.19 |
| **Assamese** | 55.59 | 59.1 | 37.29 |
| **Tamil** | 83.28 | 58.3 | 34.31 |
| **Marathi** | 79.17 | 52.8 | 40.96 |
| **Gujarati** | 84.75 | 55.9 | 39.03 |
| **Odia** | 82.03 | 62.8 | 19.67 |
| **English** | 87.63 | 67.9 | 30.49 |
