Use GPT-5.4 Mini with the OpenAI SDK

Change two settings: point the SDK at https://api.bearer.club/v1 and use your Bearer Club key, then pass openai/gpt-5.4-mini as the model.

curl https://api.bearer.club/v1/chat/completions \  -H "Authorization: Bearer $BEARER_CLUB_API_KEY" \  -H "Content-Type: application/json" \  -d '{    "model": "openai/gpt-5.4-mini",    "messages": [{"role": "user", "content": "Hello from the Club!"}]  }'

import osfrom openai import OpenAIclient = OpenAI(    base_url="https://api.bearer.club/v1",    api_key=os.environ["BEARER_CLUB_API_KEY"],  # your membership card)resp = client.chat.completions.create(    model="openai/gpt-5.4-mini",    messages=[{"role": "user", "content": "Hello from the Club!"}],)print(resp.choices[0].message.content)

import OpenAI from "openai";const client = new OpenAI({  baseURL: "https://api.bearer.club/v1",  apiKey: process.env.BEARER_CLUB_API_KEY, // your membership card});const resp = await client.chat.completions.create({  model: "openai/gpt-5.4-mini",  messages: [{ role: "user", content: "Hello from the Club!" }],});console.log(resp.choices[0].message.content);

The official OpenAI SDKs and most OpenAI-compatible tools, such as Cursor, Cline, Continue, Open WebUI and LiteLLM, work the same way; the name of the base URL setting varies by tool.
