What GPT-6 Luna is good at
Three jobs it does well from the launcher, and what comes back when you run them.
Quick answers about a page
Ask a quick question about the page and get the answer before you finish scrolling.
What it can read
Each tool only reads or calculates. History and copied text start off.
Short rewrites
Cut a long sentence down to its point.
Translating as you read
Translate a paragraph in another language as you read it, for a fraction of a cent.
What it costs in your browser
Pay OpenRouter per token. UtilEngine adds nothing.
OpenRouter lists GPT-6 Luna at $0.10 for a million input tokens and $0.50 for a million output tokens. A page of text is a few thousand tokens, so most of what you do in a browser costs cents, not dollars.
At list price a $20 month buys about 36,000 long-article summaries. You are not buying a month, though. You pay for the tokens each job uses, and the rest of your OpenRouter balance just sits there.
The extension asks OpenRouter for the fastest route, which can be a faster route at a higher rate than the one this receipt is priced on. When that route wins, the same three jobs cost about twice what you see here, and your OpenRouter activity page shows what you were actually charged.

GPT-6 Luna, answered
Is GPT-6 Luna available in UtilEngine today?
Yes. It is in the list as gpt-6-luna and calls openai/gpt-6-luna through OpenRouter with OpenRouter's :nitro speed routing.
What does GPT-6 Luna cost through UtilEngine?
Nothing beyond the one-time $49 for the extension. OpenRouter lists GPT-6 Luna at $0.10 per million input tokens and $0.50 per million output, so a page summary costs well under a cent. The extension routes for speed, so a faster route can serve the request at up to $0.20 per million in and $1 out. Requests over 272,000 input tokens bill at a long-context rate, up to $0.40 in and $1.50 out on the fastest route. Each reply shows the tokens it used, not counting web searches.
Is GPT-6 Luna good enough for everyday commands?
For short jobs, yes. Rewrites, translations, and quick questions about a page are where it fits. For long, tangled pages, set GPT-6.1 Sol on that one command and keep Luna on the rest.
Do I need an OpenAI account?
No. Your OpenRouter key covers GPT-6 Luna alongside every other model in the list, and OpenRouter handles the billing.
Does the AI act on pages?
No. Every tool it can call reads, from page text and your selection to your tabs and the web, and each call shows as a chip in the answer. It never clicks, types or submits a form.
