 # What is Yi-VL?
 
-## Overview
-
-- **Yi Vision Language (Yi-VL)** model is the open-source, multimodal version of the Yi **Large Language Model (LLM)** series, enabling content comprehension, recognition, and multi-round conversations about images.
-  
-- Yi-VL demonstrates exceptional performance, **ranking first** among all existing open-source models in the latest benchmarks including [MMMU](https://mmmu-benchmark.github.io/#leaderboard) in English and [CMMMU](https://mmmu-benchmark.github.io/#leaderboard) in Chinese (based on data available up to January 2024).
-  
-- Yi-VL-34B is the **first** open-source 34B vision language model worldwide.
-
-## Models

-## Features
-
-Yi-VL offers the following features:
-
-- Multi-round text-image conversations: Yi-VL can take both text and images as inputs and produce text outputs. Currently, it supports multi-round visual question answering with one image.
-  
-- Bilingual text support: Yi-VL supports conversations in both English and Chinese, including text recognition in images.  
-  
-- Strong image comprehension: Yi-VL is adept at analyzing visuals, making it an efficient tool for tasks like extracting, organizing, and summarizing information from images.
-  
-- Fine-grained image resolution: Yi-VL supports image understanding at a higher resolution of 448&times;448.
-
 ## Architecture
 
 Yi-VL adopts the [LLaVA](https://github.com/haotian-liu/LLaVA) architecture, which is composed of three primary components:

-## Training 
-
-### Training process
-
-Yi-VL is trained to align visual information well to the semantic space of Yi LLM, which undergoes a comprehensive three-stage training process:
-
-- Stage 1: The parameters of ViT and the projection module are trained using an image resolution of 224&times;224. The LLM weights are frozen. The training leverages an image caption dataset comprising 100 million image-text pairs from [LAION-400M](https://laion.ai/blog/laion-400-open-dataset/). The primary objective is to enhance the ViT's knowledge acquisition within our specified architecture and to achieve better alignment between the ViT and the LLM. 
-     
-- Stage 2: The image resolution of ViT is scaled up to 448&times;448, and the parameters of ViT and the projection module are trained. It aims to further boost the model's capability for discerning intricate visual details. The dataset used in this stage includes about 25 million image-text pairs, such as [LAION-400M](https://laion.ai/blog/laion-400-open-dataset/), [CLLaVA](https://huggingface.co/datasets/LinkSoul/Chinese-LLaVA-Vision-Instructions), [LLaVAR](https://llavar.github.io/), [Flickr](https://www.kaggle.com/datasets/hsankesara/flickr-image-dataset), [VQAv2](https://paperswithcode.com/dataset/visual-question-answering-v2-0), [RefCOCO](https://github.com/lichengunc/refer/tree/master), [Visual7w](http://ai.stanford.edu/~yukez/visual7w/) and so on.
-     
-- Stage 3: The parameters of the entire model (that is, ViT, projection module, and LLM) are trained. The primary goal is to enhance the model's proficiency in multimodal chat interactions, thereby endowing it with the ability to seamlessly integrate and interpret visual and linguistic inputs. To this end, the training dataset encompasses a diverse range of sources, totalling approximately 1 million image-text pairs, including [GQA](https://cs.stanford.edu/people/dorarad/gqa/download.html), [VizWiz VQA](https://vizwiz.org/tasks-and-datasets/vqa/), [TextCaps](https://opendatalab.com/OpenDataLab/TextCaps), [OCR-VQA](https://ocr-vqa.github.io/), [Visual Genome](https://homes.cs.washington.edu/~ranjay/visualgenome/api.html), [LAION GPT4V](https://huggingface.co/datasets/laion/gpt4v-dataset) and so on. To ensure data balancing, we impose a cap on the maximum data contribution from any single source, restricting it to no more than 50,000 pairs. 
-
-Below are the parameters configured for each stage.
-
-Stage | Global batch size | Learning rate | Gradient clip | Epochs
-|---|---|---|---|---
-Stage 1, 2 |4096|1e-4|0.5|1
-Stage 3|256|2e-5|1.0|2
-
-### Training resource consumption
-
-- The training consumes 128 NVIDIA A800 (80G) GPUs. 
-
-- The total training time amounted to approximately 10 days for Yi-VL-34B and 3 days for Yi-VL-6B. 
-
-## Limitations
-
-This is the initial release of the Yi-VL, which comes with some known limitations. It is recommended to carefully evaluate potential risks before adopting any models. 
-
-- Feature limitation
-  
-    - Visual question answering is supported. Other features like text-to-3D and image-to-video are not yet supported.
-    
-    - A single image rather than several images can be accepted as an input. 
- 
-- Hallucination problem
-  
-    - There is a certain possibility of generating content that does not exist in the image.
-    
-    - In scenes containing multiple objects, some objects might be incorrectly identified or described with insufficient detail.
-  
-- Resolution issue
-  
-    - Yi-VL is trained on images with a resolution of 448&times;448. During inference, inputs of any resolution are resized to 448&times;448. Low-resolution images may result in information loss, and more fine-grained images (above 448) do not bring in extra knowledge.
-    
-- Other limitations of the Yi LLM.
-
-# Why Yi-VL?
-  
-## Benchmarks
-
-Yi-VL outperforms all existing open-source models in [MMMU](https://mmmu-benchmark.github.io) and [CMMMU](https://cmmmu-benchmark.github.io), two advanced benchmarks that include massive multi-discipline multimodal questions (based on data available up to January 2024).

 # How to use Yi-VL?
 
 ## Quick start
 
-Please refer to [Yi GitHub Repo](https://github.com/01-ai/Yi/tree/main/VL) for details.
-
-## Hardware requirements
+This has been implemented into the SGLang codebase, where you can simply call this model by creating a function like so:
+```
+import sglang as sgl
 
-For model inference, the recommended GPU examples are:
+@sgl.function
+def image_qa(s, image_path, question):
+    s += sgl.user(sgl.image(image_path) + question)
+    s += sgl.assistant(sgl.gen("answer"))
 
-- Yi-VL-6B: RTX 3090, RTX 4090, A10, A30
 
-- Yi-VL-34B: 4 &times; RTX 4090, A800 (80 GB)
+runtime = sgl.Runtime(model_path="BabyChou/Yi-VL-34B",
+                      tokenizer_path="BabyChou/Yi-VL-34B")
+sgl.set_default_backend(runtime)
