Training
Trained on ~103MB of cleaned Project Gutenberg text (114 public domain books) with BPE-1500 tokenization, AdamW optimizer, cosine LR decay, and ReduceLROnPlateau. Metal GPU via Candle on Apple Silicon.
Usage
from modeling_randygpt import RandyGPTConfig, RandyGPTForCausalLM
from tokenizer_randygpt import RandyGPTTokenizer
from safetensors.torch import load_file
import torch
# Load
cfg = RandyGPTConfig.from_pretrained("MonumentalSystems/randygpt-s")
model = RandyGPTForCausalLM(cfg)
state = load_file("model.safetensors")
model.load_state_dict(state, strict=True)
model.eval()
tok = RandyGPTTokenizer.from_file("tokenizer.json")
# Generate
prompt = "Once upon a time"
ids = torch.tensor([tok.encode(prompt)], dtype=torch.long)
out_ids = model.generate_text(ids, max_new_tokens=200, temperature=0.8)
print(tok.decode(out_ids[0].tolist()))
