Usage

python

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "WestCode1357/gpt-sw3-126m-instruct"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.float16)
device = "mps" if torch.backends.mps.is_available() else "cuda" if torch.cuda.is_available() else "cpu"
model.to(device)

prompt = "Träd är fina för att"
inputs = tokenizer(prompt, return_tensors="pt").to(device)
out = model.generate(**inputs, max_new_tokens=150, do_sample=True, temperature=0.7)
print(tokenizer.decode(out[0]))

Chat / instruct format

GPT-SW3 instruct uses special tokens. The format is:

<|endoftext|><s>User: [your message]<s>Bot: [response]<s>...

python

eos = "<|endoftext|>"
seg = "<s>"
prompt = f"{eos}{seg}User: Vad är huvudstaden i Sverige?{seg}Bot: "
inputs = tokenizer(prompt, return_tensors="pt").to(device)
out = model.generate(
    **inputs, max_new_tokens=200,
    do_sample=True, temperature=0.7, top_p=0.95,
    eos_token_id=tokenizer.eos_token_id
)
print(tokenizer.decode(out[0][inputs.input_ids.shape[-1]:], skip_special_tokens=False))

Intended Use

⚠️ These models contain extreme bias and are NOT intended for commercial use. For scientific and research use only.

GPT-SW3 was trained on large-scale web data and may reflect harmful societal biases present in that data. It has not been aligned or safety-tuned beyond its original training. Use strictly in controlled research settings. Do not deploy in any consumer-facing or commercial product without thorough evaluation and additional safety measures.

About GPT-SW3

GPT-SW3 is developed by AI Sweden in collaboration with RISE and WASP WARA for Media and Language. Trained on 320B tokens: Swedish, Norwegian, Danish, Icelandic, English, and code.
