How AI Credits Work in a Multi-Model App

A credit is a single monthly budget that every model draws from. Instead of paying one vendor per subscription, you get a pool of credits and spend it on whichever model you pick: a small, cheap model uses very little, a frontier model uses more. This guide explains how that works in Quad Chat, using the numbers on its pricing page.

Direct answer: In Quad Chat, credits are shared across every model, they reset each billing period, and web searches are counted separately. The same message costs fewer credits on a lightweight model than on a flagship one, so a plan's credits do not map to a fixed number of messages. Free includes 100 credits a month; paid plans run from 600 on Go to 20,000 on Max.

What a credit is

A credit is Quad's internal unit of model usage. It exists because model providers price in tokens, and each provider uses a different rate card. Credits turn that into one number you can budget against, whichever model you choose.

Three rules cover most of the behavior:

What each plan includes

These figures come from Quad's plan configuration and match the public pricing page.

Plan Monthly price Yearly, per month Credits Web searches Chat models available
Free $0 n/a 100 100 32 of 49
Go $8 $7 600 400 32 of 49
Pro $15 $13 1,200 1,000 44 of 49
Ultra $40 $34 2,500 4,000 48 of 49
Max $200 $170 20,000 20,000 49 of 49

Yearly billing is 15% less than twelve monthly payments. Plans differ in two ways: how much usage they include, and how much of the model catalog they unlock. Video generation starts on Ultra.

Measured as credits per dollar of monthly price, Go gives 75, Pro 80, Ultra 62.5 and Max 100. That is only one lens: higher tiers also unlock more of the catalog, video generation and more file storage, so compare plans on what you will actually use.

Why credits do not equal messages

Because a credit is a budget rather than a message count, the number of messages you get depends on which models you use. The pricing page gives a sense of scale with one reference model, Claude Sonnet 5.5, assuming a typical message of about 1,500 input tokens and 700 output tokens:

Plan About this many Claude Sonnet 5.5 messages a month
Free 55
Go 500
Pro 800
Ultra 2,500
Max 12,000

Treat these as estimates for one model and one message size. Long documents, long answers and reasoning-heavy models use more. Smaller, faster models use far less, so the same plan stretches much further if you reserve flagship models for the work that needs them. The per-token pricing guide shows how much the gap between models can be.

Reading the cost before you send

Quad shows a credit estimate before you commit. In chat, the model picker shows the estimate for the model you selected. In Studio, the generation control shows "about N credits" for the image or video you are about to make. If you compare several models at once, each answer is its own generation, so comparing three models uses more of your allowance than a single answer. The side-by-side guide covers when that is worth it.

What happens when you run out

Running out of credits does not lock you out of your account. You can wait for the next period, upgrade, or buy a one-time credit pack. Unused credits do not roll over between billing periods. Bonus credits earned from referrals are the exception: they never expire.

How team plans work

Team plans use the same idea per seat. Team is $20 per seat a month with 1,500 credits and 2,000 web searches for each member. Business is $40 per seat with 4,000 credits and 5,000 web searches. Each seat has its own private allocation: credits are not pooled across the team, and admins see usage totals but never member conversations or files.

How to make credits last

When separate subscriptions still make sense

A shared credit pool suits people who spread their work across several models. If nearly all of your usage sits inside one provider and you need its native voice, memory or maximum sustained usage, a direct subscription can be the better fit. The one-subscription guide walks through that decision, and ChatGPT Plus vs Quad Pro compares a single provider's plan with Quad's Pro plan.

Summary

Credits are one shared monthly budget: cheaper models spend less, searches are counted separately, and the estimate appears before you send. Pick a plan by how much usage you need and how much of the catalog you want to unlock, not by an imagined message count.

Frequently asked questions

What is an AI credit?

A credit is Quad Chat's internal unit of model usage. Every model draws from one shared monthly pool, and cheaper models use fewer credits per message than flagship ones, so a plan's credits do not map to a fixed number of messages.

How many credits does each Quad Chat plan include?

Free includes 100 credits a month, Go 1,200, Pro 2,000, Ultra 5,000 and Max 25,000. Web search is included and uses the same credits. Team seats get 2,400 credits and Business seats 5,000, each private to the member.

What happens when I run out of credits?

You keep your account and can wait for the next billing period, upgrade, or buy a one-time credit pack. Unused monthly credits do not roll over, while bonus credits earned from referrals never expire.
