💻 Usage

With Ollama (Recommended)

# Install Ollama
curl -fsSL https://ollama.ai/install.sh | sh

# Run UVIA v1.3
ollama run uvia-1-3

# Example query
"What are the best grape varieties for Brazilian tropical climates?"

With Transformers

from transformers import AutoTokenizer, AutoModelForCausalLM

# Load model and tokenizer
model_name = "uvia-br/UVIA-v1.3"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Generate response
input_text = "Como identificar problemas de fermentação em vinhos brasileiros?"
inputs = tokenizer(input_text, return_tensors="pt")
outputs = model.generate(**inputs, max_length=512, temperature=0.7)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

With Ollama API

import requests

response = requests.post('http://localhost:11434/api/generate',
    json={
        "model": "uvia-1-3",
        "prompt": "What are the main challenges in Brazilian viticulture?",
        "stream": False
    }
)

print(response.json()['response'])
