Using the GPT3 Davinci Model for Text Generation

The first task is to load your OpenAI API key in the environment variable and import the necessary libraries.

# Import necessary libraries
import openai
import os
import IPython
from dotenv import load_dotenv

# API configuration
openai.api_key = os.getenv("OPENAI_API_KEY")

This demonstrates how to generate text using OpenAI’s GPT-3 model, here davinci model. The prompt is used as a starting point, and the ‘openai.Completion.create()’ method is used to make an API call to GPT-3 for text generation. The generated text is then printed to the console, allowing users to see the output of the text generation process.

# Define a prompt for text generation
prompt = "Once upon a time"

# Generate text using GPT-3
response = openai.Completion.create(
    max_tokens=100  # Adjust the desired length of the generated text

# Print the generated text

These advancements pave the way for more efficient, capable, and reliable LLMs that can be deployed in a wider range of applications.

Recent LLMs Developments in 2023

The issue with LLMs for commercial use is that they might not be opensource or prohibited for use. As a result, businesses might not be able to use them at all or might have to pay to do so. For reasons like transparency and the flexibility to change the code, some businesses may also prefer to use opensource models.

Commercially Available Open-Source Language Models

There are a number of commercially available open-source language models.

  • Pythia:  It contains two sets of eight models of sizes 70M, 160M, 410M, 1B, 1.4B, 2.8B, 6.9B, and 12B. The checkpoints for every model size are available in the hugging face. You can also check out the implementation on GitHub.
  • StableLM Alpha: StableLM-Tuned-Alpha is a collection of 3B and 7B parameter decoder-only language models built on top of the StableLM-Base-Alpha models and further fine-tuned on various chat and instruction-following datasets. The checkpoints for both model sizes are available in the hugging face. You can also check out the implementation on GitHub.
  • H2oGPT: h2oGPT is a fine-tuning framework for large language models (LLMs) and a chatbot UI with document(s) question-answer capabilities. Documents provide context relevant to the instruction, which helps to ground LLMs against hallucinations. You can check out the implementation on GitHub.
  • Dolly: Dolly-v2-12b, is an instruction-following large language model trained on the Databricks machine learning platform. It is not a state-of-the-art model, but it demonstrates unusually high-quality instruction following behavior that is not typical of the foundation model on which it is built. You can check out the implementation on GitHub.
  • Bloom: BLOOM is an autoregressive Large Language Model (LLM) trained on massive volumes of text data. As a result, it can generate meaningful text in 46 languages and 13 programming languages that are nearly indistinguishable from human-written material. You can check out the checkpoints for Bloom on Hugging Face.
  • Falcon: Falcon-40B is a 40B parameters, causal decoder-only model. It outperformed LLaMA, StableLM, RedPajama, MPT, and many other models. It is a pre-trained model, which should be finetuned further for most use cases. You can check out the model on Hugging Face.

How to use weights of LLMs from Hugging Face?

We will utilize Falcon7b, a pre-trained causal decoder-only model, which typically requires further fine-tuning for most use cases. However, for text generation, it has demonstrated superior performance compared to various other models.

Import Necessary Libraries

!pip install transformers
!pip install torch

from transformers import AutoTokenizer, AutoModelForCausalLM
import transformers
import torch

Load Model and Tokenizer

The next step is to instantiate an AutoTokenizer object and load the tokenizer as well as the model for the pre-trained Falcon model.

model = "tiiuae/falcon-7b-instruct" 
tokenizer = AutoTokenizer.from_pretrained(model)

Build the Model Pipeline Using Hugging Face Transformers Pipeline

It creates a text generation pipeline using the Transformers library. It specifies the task as “text-generation” and requires a pre-trained model and tokenizer. The computations are configured to utilize a 16-bit floating-point number data type.

!pip install einops
!pip install accelerate

pipeline = transformers.pipeline(

Model Inference

The task at hand is to utilize the built pipeline to print the result. The ‘prompt’ variable contains the initial text that serves as a starting point. We configure the pipeline to generate a maximum of 200 tokens, enable sampling, and consider the top 10 probable tokens at each step.

prompt = "Write a poem about Elon Musk firing Twitter employees"

sequences = pipeline(

for seq in sequences:
    print(f"Result: {seq['generated_text']}")
