API for the GPT-J language model 🦜. Including a FastAPI backend and a streamlit frontend

Last update: Dec 31, 2022

Overview

gpt-j-api 🦜

An API to interact with the GPT-J language model. You can use and test the model in two different ways:

Streamlit web app at http://api.vicgalle.net:8000/
The proper API, documented at http://api.vicgalle.net:5000/docs

Using the API

Python:

import requests
context = "In a shocking finding, scientist discovered a herd of unicorns living in a remote, previously unexplored valley, in the Andes Mountains. Even more surprising to the researchers was the fact that the unicorns spoke perfect English."
payload = {
    "context": context,
    "token_max_length": 512,
    "temperature": 1.0,
    "top_p": 0.9,
}
response = requests.post("http://api.vicgalle.net:5000/generate", params=payload).json()
print(response)

Bash:

curl -X 'POST' \
  'http://api.vicgalle.net:5000/generate?context=In%20a%20shocking%20finding%2C%20scientists%20discovered%20a%20herd%20of%20unicorns%20living%20in%20a%20remote%2C%20previously%20unexplored%20valley%2C%20in%20the%20Andes%20Mountains.%20Even%20more%20surprising%20to%20the%20researchers%20was%20the%20fact%20that%20the%20unicorns%20spoke%20perfect%20English.&token_max_length=512&temperature=1&top_p=0.9' \
  -H 'accept: application/json' \
  -d ''

Deployment of the API server

Just ssh into a TPU VM. This code was only tested on the v3-8 variants.

First, install the requirements and get the weigts:

python3 -m pip install -r requirements.txt
wget https://the-eye.eu/public/AI/GPT-J-6B/step_383500_slim.tar.zstd
sudo apt install zstd
tar -I zstd -xf step_383500_slim.tar.zstd

And just run

python3 serve.py

Then, you can go to http://localhost:5000/docs and use the API!

Deploy the streamlit dashboard

Just run

python3 -m streamlit run streamlit_app.py --server.port 8000

Comments

I've made an extensions using this api

https://chrome.google.com/webstore/detail/type-j/femdhcgkiiagklmickakfoogeehbjnbh

You can check it out here

First i was very hyped up and it felt fun, like I was talking to a machine, but then I lost my enthusiasm and now I feel like it's totally useless xD

I'm just leaving a link here for you to appreciate you, it became real thanks for you posting this api

feel free to delete the issue as it's out of scope

if you got ideas on how to make it commercially succesful - i'll be happy to partner up

api seems offline

When I try to access the API I get the following error: ERR_CONNECTION_TIMED_OUT. But when I try to connect to it using a different IP address it does work. Am I IP banned?

Usage

I'm using this to host a Discord chatbot, and though I have slowmode on the channel there's still a lot of usage, and often the API is being used as fast as it can generate completions. Will this harm the experience for others? Should I limit it more? (thanks for making this free but I don't want to take advantage of that too much if it's bad for others)

Alternative to Google TPU VM?

Hello,

I would like to run a local instance of GPT-J, but avoid using Google.

I have little to no experience in machine learning and its requirements, are there other solutions I could use? (What are the requirements for a machine in order to run GPT-J?)

Thank you very much!

Is there a way to speed up inference?

Hello, I am currently working on a project where I need quick inference. It needn't be real-time, but something around 7-10 sec would be great. Is there a way to speed up the inference using the API?

The model does not seem to be a problem as compute_time is around 8sec, but by the time the request arrives it takes around 20 seconds (over 30 on some occasions). Is there a way to make the request a bit faster?

Thanks,

How to make the api public?

Hey, I was able to get serve.py running with the instructions you gave. But now I want to make the api public and connect it to a domain name so it can be publicly accessed (without needing a connection to the vm). How can I achieve this?

I want to do the same thing you did with "http://api.vicgalle.net:5000/generate" and "http://api.vicgalle.net:5000/docs".

Thanks,

API VM?

Hi I wanted to host my own version of the api, where is the public one hosted? is it on a google cloud TPU VM? The ones ive seen here https://cloud.google.com/tpu/pricing are very expensive :D Is a TPU VM needed and the model won't be able to run on a normal GPU VM?

Thanks!

Raw text...

This is probably a very stupid question but whenever I run GPT-J I always get the full output:

{'model': 'GPT-J-6B', 'compute_time': 1.2492187023162842, 'text': ' \n(and you\'ll be a slave)\n\n**_"I\'m not a robot, I\'m a human being."_**\n\n**_"I\'m not a robot, I\'m a human being."_**\n\n', 'prompt': 'AI will take over the world ', 'token_max_length': 50, 'temperature': 0.09, 'top_p': 0.9, 'stop_sequence': None}

What parameter do I need to change so it only outputs the generated text?

(and you'll be a slave) I'm not a robot, I'm a human being. I'm not a robot, I'm a human being.

Latency with TPU VM

Got things running on Google Clouds, really happy :). Was hoping for a little but of a speed increase, but computation time is the same and latency on the request seems to be the main delay. Did you experiment with firewalls and ports to improve things?
