Welcome to the fascinating world of GPT-SW3, a large language model developed by AI Sweden, designed to generate coherent text across multiple languages! Here, we’ll explore how to use this powerful model, including code samples and troubleshooting tips. So, let’s dive right in!

What is GPT-SW3?

GPT-SW3 is a collection of advanced, decoder-only pretrained transformer language models, trained on an extensive dataset of 320 billion tokens that includes various languages such as Swedish, Norwegian, Danish, Icelandic, English, and programming code. Think of it as a multilingual library that has read countless books and articles, ready to assist you with generating text on a plethora of topics!

How to Use GPT-SW3

Here’s a step-by-step guide on how to get started with GPT-SW3 from Python:

Step 1: Log In to Hugging Face

• Since GPT-SW3 resides in a private repository, you must first log in using your access token. You can do this with the command:
• huggingface-cli login
• Refer to the HuggingFace Quick Start Guide for further assistance.

Step 2: Load the Model

Now, let’s load the model and tokenizer:

import torch
from transformers import pipeline, AutoTokenizer, AutoModelForCausalLM

model_name = "AI-Sweden-Models/gpt-sw3-126m"
device = "cuda:0" if torch.cuda.is_available() else "cpu"
prompt = "Träd är fina för att"

# Initialize Tokenizer & Model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)
model.eval()
model.to(device)

Step 3: Generate Text

With the model loaded, you can generate text using the code below:

input_ids = tokenizer(prompt, return_tensors="pt")["input_ids"].to(device)
generated_token_ids = model.generate(
    inputs=input_ids,
    max_new_tokens=100,
    do_sample=True,
    temperature=0.6,
    top_p=1,
)[0]
generated_text = tokenizer.decode(generated_token_ids)

Alternative: Using HuggingFace Pipeline

You can also utilize the HuggingFace pipeline, which simplifies the process significantly:

generator = pipeline("text-generation", tokenizer=tokenizer, model=model, device=device)
generated = generator(prompt, max_new_tokens=100, do_sample=True, temperature=0.6, top_p=1)[0]["generated_text"]

Understanding the Code with an Analogy

Imagine you are a chef preparing a unique dish (the text). Before you begin cooking (generating text), you need to gather your ingredients (loading models and tokenizers) from a well-stocked pantry (the AI Sweden repository). Using a recipe (the code snippet), you will mix your ingredients efficiently to create a delightful meal (generate coherent text) for your guests (users). If your guests want specific flavors (more diverse text outputs), you can adjust the recipe by modifying cooking techniques (parameters like temperature and sampling methods).

Troubleshooting

Even the best chefs encounter challenges in the kitchen. Here are some troubleshooting tips if things don’t go as planned:

• Issue: Access Denied Error – Ensure you have logged in with your Hugging Face token. Check your token validity.
• Issue: Out of Memory Errors – If using a large model, verify that you have enough memory available on your GPU.
• Issue: Unexpected Outputs – GPT-SW3 may produce irrelevant or repetitive outputs. Experiment with temperature and sampling settings for more diverse results.
• General Issues – Dive deeper into the community if you face persistent challenges—reach out to others, or explore documentation. For more insights, updates, or to collaborate on AI development projects, stay connected with fxis.ai.
