The commenter is annoyed but not rude. They say the new default broke their setup, that the release note buried the change, and they want a flag to turn it off.

What it costs in your browser
Pay OpenRouter per token. UtilEngine adds nothing.
Kimi K3 bills $3 for a million input tokens and $15 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 1,200 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 provider's priority tier rather than the one this receipt is priced on. When that tier wins, the same three jobs cost about 1.5x what you see here, and your OpenRouter activity page shows what you were actually charged.

Kimi K3, answered
Is Kimi K3 available in UtilEngine today?
Yes. It is in the list as kimi-k3 and calls moonshotai/kimi-k3 through OpenRouter with OpenRouter's :nitro speed routing.
What does Kimi K3 cost through UtilEngine?
Nothing beyond the one-time $49 for the extension. OpenRouter lists Kimi K3 at $3 per million input tokens and $15 per million output on the Moonshot AI route, which puts a page summary near two cents. The extension routes for speed, so a faster provider can serve the request at up to $6 per million in and $22.50 out. Each reply shows the tokens it used.
Do I need a Moonshot AI account?
No. Your OpenRouter key covers Kimi K3 and the four other Kimi models in the list, and the credit lives in your OpenRouter account.
Can I use Kimi K3 for one command and a cheaper model for another?
Yes. Each AI command stores its own model, so Kimi K3 can run Translate To while Fix Spelling and Grammar stays on the cheap default.
Does the AI act on pages?
No. Every tool is read-only and every call appears as a chip in the thread. The model reads what you allow and never clicks, types or submits a form.
