What is GPT-5.2 API pricing per million tokens?

On this key $1.75 in and $14.00 out per million tokens today, against OpenAI's list of $1.75 and $14.00; cached input $0.175. Read from the catalog at render; the figure is what you are billed. OpenAI's pricing page has its own current list.

How do I get a GPT-5.2 API key?

Here: open an account with an email address, top up from $10 by card or in USDT, USDC, BTC, ETH, SOL, create a key in the console. The key starts sk-relay- and goes in the Authorization header to https://api.relayswitch.io/v1/chat/completions with model gpt-5.2. No OpenAI account, no identity documents.

Is there a free GPT-5.2 API?

No. OpenAI bills GPT-5.2 per token and so does every gateway that resells it; the "free" results are trial credits and shared proxies that put your prompts through someone else's account. The floor here is a $10 top-up with no subscription and no expiry; the worked table says how many requests that is.

Is there a GPT-5.2 API download?

No. GPT-5.2 is a hosted model; there is nothing to download. You install an OpenAI-compatible SDK (pip install openai, npm install openai) and point it at the base URL. The weights are not distributed by OpenAI.

ChatGPT 5.2 or GPT-5.2: which is which?

ChatGPT 5.2 is the model as it appears in the ChatGPT app, on a monthly plan. GPT-5.2 is the same model family by API, billed per token: this page. The API has no ChatGPT plan attached and no login to OpenAI.

Does the GPT-5.2 API in Python need changes?

Two lines: base_url="https://api.relayswitch.io/v1" and the key. The request and response shapes are OpenAI's, including tools, response_format, streaming and the usage block. The Python example on this page runs as written with your key in RELAYSWITCH_KEY.

Is the GPT-5.3 Codex API on the same key?

Yes: gpt-5.3-codex at $1.75 in and $14.00 out per million tokens today (OpenAI: $1.75 / $14.00), in the table with the GPT-5.6 line. Point a coding agent's OpenAI base URL at the key and set the id.

What a request and a month cost

Two shapes at today's price: a chat turn (2,000 tokens in, 500 out) and a long document (50,000 in, 2,000 out). The month is 50,000 chat turns, uncached.

Model	Chat turn	Long document	50,000 turns	Same month at list
GPT 5.2	$0.0105	$0.1155	$525.00	$525.00
GPT 5.2 PRO	$0.4032	$4.44	$20,160.00	—

GPT 5.6	$0.0036	$0.0475	$178.20	—

GPT-5.6 Terra	$0.0042	$0.0672	$210.00	$500.00

Uncached input. A prompt that repeats a long system message pays the cached rate on the repeated part where the model supports it.

python

1from openai import OpenAI

3client = OpenAI(base_url="https://api.relayswitch.io/v1", api_key="sk-relay-...")

4reply = client.chat.completions.create(

5 model="gpt-5.2",

6 messages=[{"role": "user", "content": "Say hello in five words."}],

7)

3 -H "Content-Type: application/json" \

4 -d '{"model": "gpt-5.2", "messages": [{"role": "user", "content": "Hello"}]}'

Tools, response_format, streaming and the usage block are OpenAI's shapes; OpenAI's GPT-5.2 model page documents the model's limits. Swap the id for gpt-5.3-codex in a coding agent or gpt-5.6 for the newer line; the balance and the key do not change.

What is stored: the email address, the top-ups, the keys, and one usage record per request (request id, model, token counts, charge). Not stored: request and response bodies, a name, an ID, a phone number, or a card for crypto top-ups. The privacy page has the list.
