Frontier The newest generation of the GPT line in our catalogue — for general text and reasoning tasks.
General use: chat, code, summarisation and extraction, with good instruction following. Context window of 128,000 tokens.
High volume of simple work. For classification, extraction and short summaries, the lighter models in the same line do the job at a fraction of the price per token.
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.
The API speaks the OpenAI format. Swap the base_url, use a gpub_live_ key and pass gpt-6-astra 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="gpt-6-astra",
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.
