Usage

python

import os, sys, json, torch, tiktoken
from huggingface_hub import hf_hub_download
from safetensors.torch import load_file

repo_id = "gopluto-ai/slm-124m-tinystories-wiki"

cfg_path = hf_hub_download(repo_id, "config.json")
wt_path  = hf_hub_download(repo_id, "model.safetensors")
slm_path = hf_hub_download(repo_id, "slm.py")

# make the downloaded slm.py importable
sys.path.append(os.path.dirname(slm_path))
from slm import SLM

# load model
cfg = json.load(open(cfg_path))
model = SLM(**cfg)
model.load_state_dict(load_file(wt_path))
model.eval()

# tokeniser
enc = tiktoken.get_encoding("gpt2")
prompt = "Once upon a time"
ids = torch.tensor(enc.encode(prompt)).unsqueeze(0)

# generate
with torch.no_grad():
    y = model.generate(ids, max_new_tokens=50, temperature=0.9, top_k=50)
print(enc.decode(y[0].tolist()))
