What GPT-6.1 Terra is good at
Three jobs it does well from the launcher, and what comes back when you run them.
Pricing and spec pages
Ask which plan has the feature you need and get the price with it.
What it can read
Each tool only reads or calculates. History and copied text start off.
Drafts that read clearly
Turn a stiff draft into a clear, friendly note, with the ask kept.
Policy and terms changes
Pull what changed out of a long policy or terms page.
What it costs in your browser
Pay OpenRouter per token. UtilEngine adds nothing.
OpenRouter lists GPT-6.1 Terra at $1 for a million input tokens and $5 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 3,600 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-6.1 Terra, answered
Is GPT-6.1 Terra available in UtilEngine today?
Yes. It sits in the model list as gpt-6.1-terra and calls openai/gpt-6.1-terra through OpenRouter with OpenRouter's :nitro speed routing.
What does GPT-6.1 Terra cost through UtilEngine?
Nothing beyond the one-time $49 for the extension. OpenRouter lists GPT-6.1 Terra at $1 per million input tokens and $5 per million output, half of GPT-6.1 Sol, which puts a page summary under a cent. The extension routes for speed, so a faster route can serve the request at up to $2 per million in and $10 out. Requests over 272,000 input tokens bill at a long-context rate, up to $4 in and $15 out on the fastest route. Each reply shows the tokens it used, not counting web searches.
What changed from GPT-5.6 Terra?
OpenAI calls it a significant step up, with clearer writing and fewer errors in its own tests, at a lower price per token. GPT-5.6 Terra stays in the list, so a command set to it keeps running on it until you change it.
Do I need ChatGPT Plus to use it?
No. GPT-6.1 Terra runs on your OpenRouter key, not a ChatGPT plan. One key reaches it and the other 88 models in the list.
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.
