Frontier Revisão mais recente do modelo mais capaz da Anthropic. Preço de topo — use quando o acerto vale mais que o custo.
The problem the others cannot solve — long reasoning and hours-long autonomous work. Context window of 1,000,000 tokens.
Anything cost- or latency-sensitive; it is the most expensive model in the catalogue.
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 claude-fable-5-1 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-fable-5-1",
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.
