GLM 5.3
What is this build log actually complaining about?
The test step never ran. The install before it stopped on a lockfile that does not match package.json. Everything after that line is the same error printed again.

Translate a page of dense paragraphs in one request instead of paragraph by paragraph, and the token price stays low.
What it costs in your browser
Pay OpenRouter per token. UtilEngine adds nothing.
GLM 5.3 bills $1.40 for a million input tokens and $4.40 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 2,900 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.

GLM 5.3, answered
Is GLM 5.3 available in UtilEngine today?
Yes. It is in the list as glm-5.3 and calls z-ai/glm-5.3 through OpenRouter with OpenRouter's :nitro speed routing.
What does GLM 5.3 cost through UtilEngine?
Nothing beyond the one-time $49 for the extension. OpenRouter lists GLM 5.3 at $1.40 per million input tokens and $4.40 per million output on the Z.AI route, so a page summary costs under a cent. The extension routes for speed, so a faster provider can serve the request at up to $2.10 per million in and $6.60 out. Each reply shows the tokens it used.
Do I need a Z.AI account?
No. One OpenRouter key reaches GLM 5.3 and the eight other Z.AI models in the list, and you top up credit on OpenRouter.
Can I use GLM 5.3 for one command and a cheaper model for another?
Yes. The model is a per-command setting, so GLM 5.3 can handle Ask About Page while the shorter commands stay on GLM 5.3 Flash.
Does the AI act on pages?
No. The tools read page text, your selection, tabs, history, bookmarks and downloads, and that is the whole list. Nothing clicks, types or fills a form.
