TeenyTinyLlama-162m
Model Summary
Given the lack of available monolingual foundational models in non-English languages and the fact that some of the most used and downloaded models by the community are those small enough to allow individual researchers and hobbyists to use them in low-resource environments, we developed the TeenyTinyLlama: a series of small foundational models trained on Portuguese.
TeenyTinyLlama is a compact language model based on the Llama 2 architecture (TinyLlama implementation). This model is designed to deliver efficient natural language processing capabilities while being resource-conscious.
Also, these models were trained by leveraging scaling laws to determine the optimal number of tokens per parameter while incorporating preference pre-training.

Intended Uses
TeenyTinyLlama is intended for research purposes only. Given the nature of the training data, this l model is best suited for prompts using the QA format or for text completion/generation.
Basic usage
Using the pipeline:
from transformers import pipeline
generator = pipeline("text-generation", model="nicholasKluge/Teeny-tiny-llama-162m")
completions = generator("Astronomia é a ciência", num_return_sequences=2, max_new_tokens=100)
for comp in completions:
print(f"🤖 {comp['generated_text']}")
Using the AutoTokenizer and AutoModelForCausalLM:
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
# Load model and the tokenizer
tokenizer = AutoTokenizer.from_pretrained("nicholasKluge/Teeny-tiny-llama-162m", revision='main')
model = AutoModelForCausalLM.from_pretrained("nicholasKluge/Teeny-tiny-llama-162m", revision='main')
# Pass the model to your device
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model.eval()
model.to(device)
# Tokenize the inputs and pass them to the device
inputs = tokenizer("Astronomia é a ciência", return_tensors="pt").to(device)
# Generate some text
completions = model.generate(**inputs, num_return_sequences=2, max_new_tokens=100)
# Print the generated text
for i, completion in enumerate(completions):
print(f'🤖 {tokenizer.decode(completion)}')
Limitations
Hallucinations: This model can produce content that can be mistaken for truth but is, in fact, misleading or entirely false, i.e., hallucination.
Biases and Toxicity: This model inherits the social and historical stereotypes from the data used to train it. Given these biases, the model can produce toxic content, i.e., harmful, offensive, or detrimental to individuals, groups, or communities.
Unreliable Code: The model may produce incorrect code snippets and statements. These code generations should not be treated as suggestions or accurate solutions.
Language Limitations: The model is primarily designed to understand standard Portuguese (BR). Other languages might challenge its comprehension, leading to potential misinterpretations or errors in response.
Repetition and Verbosity: The model may get stuck on repetition loops (especially if the repetition penalty during generations is set to a meager value) or produce verbose responses unrelated to the prompt it was given.
