1. 1
   GPT-6 Astra

   OpenAI's flagship for the hardest reasoning and professional work. The most expensive step.

2. 2
   GPT-6.1 Sol

   Close to Astra on agentic coding and document work at a much lower price. A good default for most products.

Pro mode and reasoning effort

Every GPT-6 model takes an adjustable reasoning effort, from low for quick answers to max for hard problems. A higher level means more thinking tokens, so more cost and a longer wait. For chat and simple tasks, low or medium is enough.

The "Pro" versions (such as GPT-6 Astra Pro and GPT-6.1 Sol Pro) are the same models run in pro mode. The per-token price is the same, but they reason much more, so a typical request costs several times as much. Use them only where a wrong answer is expensive.

What would a month cost?

Three common scenarios at live Hormouz prices. These are estimates; real cost depends on message length.

Image generation and editing with OpenAI models

OpenAI's image models are reached through the Hormouz /v1/predictions endpoint and are priced per image.

• gpt-image-2

  Everyday image editing and generation; the most used on Hormouz.

  Price

  $0.0120 – $0.1280 / number_of_images

• gpt-image-2.5-flare

  The fast tier of GPT Image 2.5, for volume.

  Price

  $0.0120 – $0.5000 / number_of_images

• gpt-image-2.5-sunburst

  The precise tier of GPT Image 2.5, for detailed edits.

  Price

  $0.0120 – $0.5000 / number_of_images

The OpenAI code you write today works with Hormouz

Only base_url and the key change. The rest of your code, including streaming and tool calls, stays the same.

from openai import OpenAI

client = OpenAI(base_url="https://api.hormouz.net/v1", api_key="YOUR_HORMOUZ_KEY")

reply = client.chat.completions.create(
    model="openai/gpt-6.1-sol",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(reply.choices[0].message.content)

import OpenAI from "openai";

const client = new OpenAI({ baseURL: "https://api.hormouz.net/v1", apiKey: "YOUR_HORMOUZ_KEY" });

const reply = await client.chat.completions.create({
  model: "openai/gpt-6.1-sol",
  messages: [{ role: "user", content: "Hello!" }],
});
console.log(reply.choices[0].message.content);

FAQ

Is the ChatGPT API the same as ChatGPT?

ChatGPT is OpenAI's app; the API gives your program the same GPT models. With the API you choose the model and build the interface yourself.

Do I need an OpenAI account or a Plus subscription?

No. You need only a Hormouz account and an API key.

My code is written for OpenAI. Do I have to change it?

No. In the official OpenAI SDK set base_url to https://api.hormouz.net/v1 and use your Hormouz key.

Is Pro worth it?

Only for hard, high-stakes problems. For daily work the same model without Pro, at a suitable reasoning effort, is enough and several times cheaper.

How do I pay?

You buy credit with an Iranian bank card through the gateway in the dashboard, and each request is taken from it.
