OpenAI: GPT-6 Sol and Luna cut the API price, not the recipient
OpenAI adds GPT-6 Sol and GPT-6 Luna under Astra. The Sol API goes from 4 to 2 dollars per million input tokens, and from 20 to 10 output, against GPT-5.6 promotional pricing. Luna drops to 0.10 and 0.50. The text still leaves for OpenAI.

Key points
The page does not replace the 29 September note on GPT-6.1 Sol. It comes before it, and a 29 September box points to 6.1. The useful choice here is the price of a call, not a new local chat.
What changes
The product list dates the announcement to 22 September 2026. The page itself carries a 29 September box that points to GPT-6.1 Sol. The body presents Sol and Luna as a way to spread Astra’s intelligence to cheaper work. The table shows a 50 percent cut against GPT-5.6 promotional prices: Sol at 2 and 10 dollars per million, Luna at 0.10 and 0.50.
Astra remains, on this page, the model the publisher calls the best. Sol and Luna are the step below. The page also has sections on computer use and caching long conversations. We do not carry the scores over.
What leaves
A price cut in half does not bring the request back to your machine. Sol and Luna are API models. The context you send, especially if it is cached so the next call costs less, has already left the computer.
Computer use, if it is on in the tool that calls the API, adds actions, not only sentences. This note did not open that tool.
What we did not verify
We did not call the API, or compare a GPT-5.6 bill with a GPT-6 bill. The 22 September date comes from the product list. The body of the announcement does not repeat it.
The decision
If you pay for the API, the figure to reread is the table: 2 and 10 for Sol, 0.10 and 0.50 for Luna, per million tokens. If you were looking for 6.1 Sol, that is the other note. This one is the earlier step, still hosted.
