Where it does well

Hard code, large refactors and multi-step work where a mistake is expensive. Context window of 1,000,000 tokens.

Where it is not the best choice

High volume of simple tasks — for classification or field extraction a smaller model does the same for a fraction of the price.

What changes when you pay in reais

Buying direct from the maker means paying in dollars plus two things that are not on their price list: Brazil's 3.5% IOF tax and your card issuer's FX spread, usually another 2% to 4% and never itemised. Here you are billed in reais, with neither.

The price in reais is also fixed: when the dollar rises, the maker price rises on your statement and this one does not.

How to use it on GPUBrasil

The API speaks the OpenAI format. Swap the base_url, use a gpub_live_ key and pass claude-opus-5 as the model.

from openai import OpenAI

client = OpenAI(
    base_url="https://gpubrazil.com/v1",
    api_key="gpub_live_...",
)

r = client.chat.completions.create(
    model="claude-opus-5",
    messages=[{"role": "user", "content": "Explain what a token is."}],
)
print(r.choices[0].message.content)

The same endpoint works in Cursor, Cline, Continue, Zed, Aider, Open WebUI and LibreChat — they all accept an OpenAI-compatible endpoint.
