Usage

Loading Pretrained Weights

import torch
from maba.model import Model
from maba.config import Config
from maba.tokenizer import Tokenizer
from huggingface_hub import hf_hub_download
from safetensors.torch import load_file

# Initialize model
cfg = Config.from_preset("100M")
model = Model(cfg)

# Load safetensors weights
weights_path = hf_hub_download(repo_id="AndrewThompson1233/maba-101m", filename="model.safetensors")
state_dict = load_file(weights_path)
model.load_state_dict(state_dict)
model.eval()

tok = Tokenizer()
prompt = "Once upon a time in a quiet village"
input_ids = torch.tensor([tok.encode(prompt, add_bos=True)])

with torch.no_grad():
    output_ids = model.generate(input_ids, max_new_tokens=40, temperature=0.7)

print(tok.decode(output_ids[0].tolist()))

High-Speed Speculative Generation (k=2)

from maba.generate import spec_gen

output_text, acceptance_rate, steps = spec_gen(
    model,
    tok,
    prompt="A young inventor built a clockwork bird",
    max_new_tokens=60
)
print(output_text)
