Inside psyrenne: Which AI Model Should You Use?

psyrenne’s writing comes from Claude, a family of AI models made by Anthropic. Some are quick and cheap, some are slower and sharper. Picking the right one for the job is the easiest way to make your credits last.

The short version

• Standard for almost everything. It’s the default for a reason.
• Quick when the product is simple and you need a pile of scripts fast.
• Best for your money-makers: big launches, tricky products, scripts you’ll film more than once.
• Extra if you’ve tried it, love it, and don’t mind spending more credits.

The models, in plain English

Quick (Claude Haiku 4.5): ½ credit per script

Fast and cheap. Great for simple products with a clear selling point (a phone stand, a lint roller, a water bottle) and for batches when you just need options to choose from. The writing is plainer, so expect to add your own personality.

Standard (Claude Sonnet 5.5): 1 credit per script

The everyday workhorse. Good writing, follows your voice and rules well, and handles most products without fuss. If you’re not sure, pick this one.

Best (Claude Opus 5.5): 2 credits per script

The strongest writer, included with Thelxiope. It’s better at products that need explaining (skincare, supplements, gadgets with five features), at sounding natural in your voice, and at hooks that don’t sound like every other video. It costs twice as much, so save it for the scripts that matter.

Extra · Fable 5.1 (about 5 credits)

The most capable model psyrenne offers, and the priciest: about two and a half times the cost of Best. For a 30-second product script it’s usually more brain than you need, but if you’ve tried it and love what it writes, it’s yours to use. Just keep an eye on your credits.

Which model for which part of psyrenne

• Generate (writing scripts): you choose. Standard by default; Quick for simple products or big batches; Best for your top sellers; Extra if you love it. Change your default in Settings.
• Script checker: uses Standard with extra “thinking” time, because catching risky wording needs care. About 1 to 2 credits per check. The instant word check while you type is free.
• Fill in from the web (products): Quick by default, since it’s mostly looking things up. Switch to Standard (“more thorough”) when the product page is confusing, or the details come back thin.
• Guidance: uses Standard, because it reasons about your numbers. It costs a few credits each time it refreshes.
• Everything you type yourself (products, samples, your calendar, your sales file): no AI, no credits, ever.

How to save credits without settling

• Fill in your product facts first. Every model writes better with ingredients, sizes, and “how to use” already filled in, so you need fewer do-overs.
• Start with Standard, and only rerun with Best if the scripts feel flat.
• Ask for fewer variations. Three good scripts beat six you won’t film.
• Check your Credit usage page (click the ⚡ credits at the top of any page) to see where your credits went each month.

Why I tell you the model names

Because it’s your money and your scripts. psyrenne uses AI to write and check, and I’d rather you know exactly which tool is doing it. More on how psyrenne uses AI in the AI Policy.
