This tiny model is intended for debugging. It is randomly initialized using the configuration adapted from KORMo-Team/KORMo-10B-sft.

Example usage:

python

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline

model_id = "tiny-random/kormo"
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    trust_remote_code=True,
)
pipe = pipeline('text-generation', model=model, tokenizer=tokenizer, trust_remote_code=True)
print(pipe('Write an article about Artificial Intelligence.'))
