Claude, GPT or MiniMax? Choosing AI engines per client

There is no “best model” — there’s the best model for this client at this price. A boutique with 200 chats a month can afford the flagship; a high-volume store may want the economical option.

A catalog with real prices

Pexpy ships a model catalog with per-token prices you can edit. Pick a provider and model from a dropdown — Claude Opus, GPT-5, MiniMax — and the platform prices every reply automatically.

Margins you can see

The margin calculator projects what a month costs you and what you bill, before you commit. Usage reports then show actuals per client: replies, tokens, cost, charge, margin.

Keys are yours, stored encrypted, entered once in the admin panel. Clients never see them — they just see answers.
