QuantFactory/sabia-7b-GGUF
This is quantized version of maritaca-ai/sabia-7b created using llama.cpp
Original Model Card
Sabiá-7B is Portuguese language model developed by 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
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.
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.
model = LlamaForCausalLM.from_pretrained(
"maritaca-ai/sabia-7b",
device_map="auto",
low_cpu_mem_usage=True,
load_in_8bit=True, # Requires pip install bitsandbytes
)
