OpenAI, and why this page is half a page

OpenAI makes ChatGPT, and its developer documentation lists three GPT-5.6 models with prices and context windows: Sol at $5 and $30, Terra at $2 and $12, Luna at $0.20 and $1.20. You will find no number about ChatGPT itself on this page, and the reason is written further down.

  • three GPT-5.6 models
  • 1.05M token window
  • consumer pages unread

Products

ChatGPT and Sora sit in our data with no page of their own, because we have read no fact about either from the maker own site.

What we have actually read

The API models page lists three frontier models, each with an id, a price and a knowledge cutoff. GPT-5.6 Sol is presented for complex professional work at $5 in and $30 out. Terra balances intelligence against cost at $2 and $12. Luna is for cost-sensitive workloads at $0.20 and $1.20. All three carry a 1.05M token context window, up to 128K of output, and a knowledge cutoff of 16 February 2026.

Beside them the page lists GPT Image 2 for images, the realtime line for live voice, transcription models and a text to speech model. The developer platform has three parts: the API, Codex as a coding agent across desktop, web, CLI and cloud, and plugins written as skills and MCP servers for ChatGPT and Codex.

What we have not read, and why

Every path on openai.com returns 403 to this server. We have tried it with a browser user agent, and we ran it again on 12 August 2026: the domain root and the ChatGPT pricing page both answered 403, while robots.txt on that same domain opens with a 200 and does not disallow crawling. The obstacle is a bot protection layer, not a rule we would be breaking.

The consequence is that ChatGPT plan prices, its feature list, the countries it serves and even the current version name of Sora are not available to us from the maker own source. We could write them from memory and the page would look complete. That is what the other round-ups do, and it is the thing this reference was built to replace.

When this hole gets filled

The day openai.com answers this server. This page, the ChatGPT entry and the Iran column all get filled with a fresh read date, and the change log records it. Until then, the empty cell is our answer.

What it is good at

  • The API documentation is candid: id, price, context window and knowledge cutoff for all three models on one page
  • Three price steps inside one model generation, from $0.20 to $5 of input, which makes the cost choice simple
  • A 1.05M token window on all three models, larger than the one million of its direct rivals
  • Codex, an official coding agent running on desktop, web, CLI and cloud

Where it falls short

  • There is no fact about ChatGPT on this page, because the consumer pages on openai.com return 403 to this server and we do not write from memory.
  • The prices here are API prices, not what a ChatGPT subscriber pays. The two should not be conflated.
  • The Sora model id is absent from the API models page, so we have nothing measurable about OpenAI video.
  • We have not read a supported-countries list, so the Iran column for this maker reads unchecked.
  • For the same reason, the ChatGPT candidate sits in our rankings with every cell empty and takes no rank.

Our take

For a developer working against the API, OpenAI is fully assessable and the documentation is clear. For somebody shopping for ChatGPT, this page is no use today, and we would rather say so than invent a plausible number.

Questions people actually ask

Why is the ChatGPT subscription price missing

Because we could not read its pricing page. openai.com returns 403 to this server even with a browser header, while robots.txt does not disallow crawling. A number we have not read from the maker own source does not get printed.

So is GPT-5.6 the same thing as ChatGPT

No. GPT-5.6 names a model line with three versions, Sol, Terra and Luna, sold through the API. ChatGPT is a product, and which model runs underneath it today is something to read on the product page, which is exactly the page that will not open for us.
