Tweety-Tatar-7B: A Tatar Large Language Model

Tweety Tatar / Base 7b / 2024-v1

Model description

This model is our trans-tokenized LLM for the Tatar language, converted from the Mistral-7B-Instruct-v0.2 model trained by MistralAI. Trans-tokenized LLMs are language models finetuned to produce output in a particular language, using a novel tokenizer native to that language.

Developed by: François Remy (UGent), Alfiya Khabibullina (BeCode), et al.
Funded by: IDLab / GPULab (UGent)
Model type: Foundation model using the mistral architecture
Language(s) (NLP): Tatar
License: Apache 2.0

In-scope usage

This model can be used as-is to perform basic language modeling operations in Tatar, or finetuned to perform more complex operations. This model has not undergone Instruction- or Chat-based finetuning, which means that the model functions best in few-shot settings.

Usage instructions

This model can be used just like any LLM in the HuggingFace framework:

import transformers

MODEL_NAME = "Tweeties/tweety-tatar-base-7b-2024-v1"
generate = transformers.pipeline("text-generation", model=MODEL_NAME)

Word Analogies

ANALOGY_PROMPT = """Бу аналоглар таблицасын тутырыгыз:
* {x1} : {y1}
* {x2} :"""
def score_analogy(x1, y1, x2, y2):
    Y2_PROMPT = ANALOGY_PROMPT.replace('{x1}', x1).replace('{y1}', y1).replace('{x2}', x2)
    answer = generate(Y2_PROMPT, use_cache=True, do_sample=False, max_new_tokens=10, return_full_text=False, pad_token_id=generate.tokenizer.eos_token_id, eos_token_id=generate.tokenizer.convert_tokens_to_ids(['<0x0A>','</s>']))[0]['generated_text'].strip()
    return 1 if answer == y2 else 0

score_analogy('Мәскәү', 'Русия', 'Әнкара', 'Төркия') # 1
