Sabiá-7B is Portuguese language model developed by [Maritaca AI](https://www.maritaca.ai/).

**Input:** The model accepts only text input.

**Output:** The Model generates text only.

**Model Architecture:** Sabiá-7B is an auto-regressive language model that uses the same architecture of LLaMA-1-7B.

**Tokenizer:** It uses the same tokenizer as LLaMA-1-7B.

**Maximum sequence length:** 2048 tokens.

**Pretraining data:** The model was pretrained on 7 billion tokens from the Portuguese subset of ClueWeb22, starting with the weights of LLaMA-1-7B and further trained for an additional 10 billion tokens, approximately 1.4 epochs of the training dataset.

**Data Freshness:** The pretraining data has a cutoff of mid-2022.

**License:** The licensing is the same as LLaMA-1's, restricting the model's use to research purposes only.

**Paper:** For more details, please refer to our paper: [Sabiá: Portuguese Large Language Models](https://arxiv.org/pdf/2304.07880.pdf) 


## Few-shot Example

Given that Sabiá-7B was trained solely on a language modeling objective without fine-tuning for instruction following, it is recommended for few-shot tasks rather than zero-shot tasks, like in the example below.

```python
import torch
from transformers import LlamaTokenizer, LlamaForCausalLM

tokenizer = LlamaTokenizer.from_pretrained("maritaca-ai/sabia-7b")
model = LlamaForCausalLM.from_pretrained(
    "maritaca-ai/sabia-7b",
    device_map="auto",  # Automatically loads the model in the GPU, if there is one. Requires pip install acelerate
    low_cpu_mem_usage=True,
    torch_dtype=torch.bfloat16   # If your GPU does not support bfloat16, change to torch.float16
)  

prompt = """Classifique a resenha de filme como "positiva" ou "negativa".

Resenha: Gostei muito do filme, é o melhor do ano!
Classe: positiva

Resenha: O filme deixa muito a desejar.
Classe: negativa

Resenha: Apesar de longo, valeu o ingresso.
Classe:"""

input_ids = tokenizer(prompt, return_tensors="pt")

output = model.generate(
    input_ids["input_ids"].to("cuda"),
    max_length=1024,
    eos_token_id=tokenizer.encode("\n"))  # Stop generation when a "\n" token is dectected

# The output contains the input tokens, so we have to skip them.
output = output[0][len(input_ids["input_ids"][0]):]

print(tokenizer.decode(output, skip_special_tokens=True))
```

If your GPU does not have enough RAM, try using int8 precision.
However, expect some degradation in the model output quality when compared to fp16 or bf16.
```python
model = LlamaForCausalLM.from_pretrained(
    "maritaca-ai/sabia-7b",
    device_map="auto",
    low_cpu_mem_usage=True,
    load_in_8bit=True,  # Requires pip install bitsandbytes
)
```
