bilingual-gpt-neox-4b-minigpt4
Overview
This repository provides an English-Japanese bilingual multimodal conversational model like MiniGPT-4 by combining GPT-NeoX model of 3.8 billion parameters and BLIP-2.
The model is based on rinna/bilingual-gpt-neox-4b and BLIP-2.
Model architecture
Similar with BLIP-2 and Vision-CAIR/MiniGPT-4, the model consists of an LLM, vision-encoder with ViT and Q-Former, and linear-layer for connecting the LLM and vision-encoder.
rinna/bilingual-gpt-neox-4b(A 36-layer, 2816-hidden-size transformer-based language model) is used as the LLM instead of Vicuna, which is used in the original Vision-CAIR/MiniGPT-4.Finetuning
The finetuning data is the subset of the following datasets.
- English datasets
- Japanese datasets
Based on the implementation of Vision-CAIR/MiniGPT-4, only "first pretraining stage" described in MiniGPT-4 paper with the above datasets was conducted, and "second-stage finetuning" proposed in the paper with an aligned image-text dataset created with ChatGPT was NOT conducted.

I/O Format
A special format has been adopted to construct inputs.
- An input prompt is formatted as a conversation between
ユーザーandシステム. - Each input utterance consists of (1) its speaker (
"ユーザー"or"システム"), (2) a colon (":"), (3) a whitespace (" "), and (4) utterance text (e.g."猫はどんな体勢をしていますか？"). - An utterance including an image is formatted as (1) its speaker (
"ユーザー"), (2) a colon (":"), (3) a whitespace (" "), (4) a placeholder of the image ("<Img><ImageHere></Img>"), (5) another whitespace (" "), (6) utterance text (e.g."What can you see?").- The placeholder (
<ImageHere>) is automatically replaced with the embedding of an input image in the functionget_context_emb.
- The placeholder (
- The input prompt should be ended with
"システム: "to acknowledge the model to generate a response. - All the utterances in the input prompt should be separated by a newline
\n.
Following is an example to construct input from a conversation.
prompt = [
{
"speaker": "ユーザー",
"text": "<Img><ImageHere></Img> What can you see?"
},
{
"speaker": "システム",
"text": "a cat on a table with a laptop"
},
{
"speaker": "ユーザー",
"text": "猫はどんな体勢をしていますか？"
},
]
prompt = [
f"{uttr['speaker']}: {uttr['text']}"
for uttr in prompt
]
prompt = "\n".join(prompt)
prompt = (
prompt
+ "\n"
+ "システム: "
)
print(prompt)
"""
ユーザー: <Img><ImageHere></Img> What can you see?
システム: a cat on a table with a laptop
ユーザー: 猫はどんな体勢をしていますか？

How to use the model
1. Download dependencies
- BLIP-2 implementation included in MiniGPT-4 is used for inference.
customized_mini_gpt4.pyis a script to replace LLM from LLaMA architecture to GPT-NeoX one.checkpoint.pthis a finetuned weight of the linear layer (file size: 177 MB).
git clone https://github.com/Vision-CAIR/MiniGPT-4.git
cd ./MiniGPT-4
