+# Mistral-portuguese-luana-7b-chat

+</p>
+This model was trained with a superset of 290,000 chat in Portuguese.
+The model comes to help fill the gap in models in Portuguese. Tuned from the Mistral 7b in Portuguese, the model was adjusted mainly for chat.
+# How to use
+### FULL MODEL : A100
+### HALF MODEL: L4
+### 8bit or 4bit : T4 or V100
+You can use the model in its normal form up to 4-bit quantization. Below we will use both approaches.
+Remember that verbs are important in your prompt. Tell your model how to act or behave so that you can guide them along the path of their response.
+Important points like these help models (even smaller models like 7b) to perform much better.
+```python
+!pip install -q -U transformers
+!pip install -q -U accelerate
+!pip install -q -U bitsandbytes
+from transformers import AutoModelForCausalLM, AutoTokenizer, TextStreamer
+model = AutoModelForCausalLM.from_pretrained("rhaymison/Llama3-portuguese-luana-8b-instruct", device_map= {"": 0})
+tokenizer = AutoTokenizer.from_pretrained("rhaymison/Llama3-portuguese-luana-8b-instruct")
+model.eval()
+```
+You can use with Pipeline.
+```python
+from transformers import pipeline
+stop_token = "<|eot_id|>"
+stop_token_id = tokenizer.encode(stop_token)[0]
+pipe = pipeline("text-generation",
+                model=model,
+                tokenizer=tokenizer,
+                do_sample=True,
+                max_new_tokens=256,
+                num_beams=2,
+                temperature=0.3,
+                top_k=50,
+                top_p=0.95,
+                early_stopping=True,
+                eos_token_id=stop_token_id,
+                pad_token_id=tokenizer.eos_token_id,
+                )
+def format_dataset(question:str):
+    system_prompt = "Abaixo está uma instrução que descreve uma tarefa, juntamente com uma entrada que fornece mais contexto. Escreva uma resposta que complete adequadamente o pedido."
+    return f"""<|begin_of_text|><|start_header_id|>system<|end_header_id|>
+    { system_prompt }<|eot_id|><|start_header_id|>user<|end_header_id|>
+    { question }<|eot_id|><|start_header_id|>assistant<|end_header_id|>"""
+prompt =  format_dataset("Me explique quem eram os Romanos")
+result = pipe(prompt)
+result[0]["generated_text"].split("assistant<|end_header_id|>")[1]
+#Os romanos eram um povo antigo que habitava a península italiana, particularmente na região que hoje é conhecida como Itália. Eles estabeleceram o Império Romano,
+#que se tornou uma das maiores e mais poderosas civilizações da história. Os romanos eram conhecidos por suas conquistas militares, sua arquitetura e engenharia
+#impressionantes e sua influência duradoura na cultura ocidental.
+#Os romanos eram uma sociedade complexa que consistia em várias classes sociais, incluindo senadores, cavaleiros, plebeus e escravos.
+#Eles tinham um sistema de governo baseado em uma república, onde o poder era dividido entre o Senado e a Assembléia do Povo.
+#Os romanos eram conhecidos por suas conquistas militares, que os levaram a expandir seu império por toda a Europa, Ásia e África.
+#Eles estabeleceram uma rede de estradas, pontes e outras estruturas que facilitaram a comunicação e o comércio.
+```
+If you are having a memory problem such as "CUDA Out of memory", you should use 4-bit or 8-bit quantization.
+For the complete model in colab you will need the A100.
+If you want to use 4bits or 8bits, T4 or L4 will already solve the problem.
+# 4bits example
+```python
+from transformers import BitsAndBytesConfig
+import torch
+nb_4bit_config = BitsAndBytesConfig(
+    load_in_4bit=True,
+    bnb_4bit_quant_type="nf4",
+    bnb_4bit_compute_dtype=torch.bfloat16,
+    bnb_4bit_use_double_quant=True
+)
+model = AutoModelForCausalLM.from_pretrained(
+    base_model,
+    quantization_config=bnb_config,
+    device_map={"": 0}
+)
+```
