How Much Does It Cost to Use All AI Models in 2026?

Paying for every major AI tool on its own (ChatGPT Plus, Claude Pro, Gemini, Grok, Perplexity, and a Mistral plan) adds up to roughly $125 per month in 2026, and it climbs past $160 the moment you add a dedicated image generator or jump to a premium tier like ChatGPT Pro. One app that bundles the same models, such as MultiChats, covers them from $20.99 per month. Below is the itemized math so you can check it yourself.

Full disclosure: MultiChats is our app, so we have a stake in this answer. Every competitor price below is a public list rate as of mid 2026, so the math is yours to verify.

The short answer

Bought individually, the main consumer AI subscriptions land around $125 a month for six chat tools. Add premium image generation and you are over $150. Pick top tiers (ChatGPT Pro runs $200 a month on its own) and the bill gets silly fast. A single multi-model app like MultiChats gives you GPT-5, Claude, Gemini, Grok, Mistral, Perplexity, and 50+ models for $20.99 a month, which is roughly 83% less than stacking the subscriptions. If you only ever use one model, one $20 plan is fine. The savings show up the second you use two or more.

What each AI tool costs on its own (2026)

These are the headline consumer plans most people actually buy. Prices are public list rates in USD, exclude tax, and ignore higher tiers (which cost far more). Feel free to bookmark this table as a reference; it is the kind of number that changes a few times a year.

That works out to roughly $1,500 a year, before tax. It climbs quickly if you add a dedicated image generator (often $9 to $30 a month), pick a top tier like ChatGPT Pro at $200 a month, or pay for extra seats. We dug into the individual-versus-bundle question in more detail in our piece on why people stop paying for multiple AI subscriptions.

The bundled-app option

A multi-model app puts all of these behind one bill. MultiChats includes 50+ models (GPT-5, Claude Opus 4.6, Gemini 3.1, Grok, Mistral, and more) plus real-time web search, image generation, saved memories, folders, and voice. You can switch models mid-conversation without losing context, so you use the right model for each task instead of paying six companies for the privilege of guessing. The idea of one subscription for all the AI models is the whole point.

The annual Pro plan ($199.99) works out to about $16.67 a month, which saves roughly $52 over paying monthly. Pro+ annual ($349.99) is about $29.17 a month.

It helps to think about why six separate plans cost what they do. Each provider charges roughly $15 to $30 a month to cover its own infrastructure and to push you toward its ecosystem. You end up paying for overlapping capabilities (every one of them does chat, most do image generation, several do search) and using maybe a third of what you bought. A bundle removes that overlap. You pay once for the layer that matters to you, which is access, and you get to pick the strongest model for each job rather than defaulting to whichever app you happened to open. MultiChats works the same way on iOS, Android, and the web, so the bill does not multiply by device or platform either.

How much you actually save

Stacking the six chat tools above runs about $125 a month. One MultiChats Pro plan is $20.99 a month, a saving of roughly $104 every month, or about $1,250 a year. On the annual plan the gap is wider still against the $1,500 or so you would otherwise spend.

• Stacked subscriptions: about $125 / mo (about $1,500 / yr)

• MultiChats Pro: $20.99 / mo ($199.99 / yr)

• Estimated saving: about $104 / mo (about $1,250 / yr)

The savings are real, but the convenience is what most people notice first: one login, one bill, one place to reach for whichever model fits the job.

Per-feature cost: image generation, voice, and web search

These are the hidden extras that quietly push separate subscriptions higher. With MultiChats they come with the plan instead of being add-ons.

• Image generation: included on Pro, with multi-image on Pro+, instead of a separate $9 to $30 a month image tool.

• Web search: real-time, multi-source search is built in, covering the use case people buy Perplexity Pro for. You can also read any webpage by pasting its URL.

• Voice mode: voice messages and voice calls on mobile, no extra charge. See how it stacks up in our look at the best AI voice mode.

On the chat side, MultiChats keeps limits transparent and shares one message pool across models, so you do not get silently downgraded to a weaker model when a provider hits its quota. There are also no ads and no training on your data. Add up just these three extras across separate apps (an image tool, a search subscription, and any voice add-on) and you are often looking at another $30 to $50 a month on top of the chat plans, which is most of the gap between the stacked total and a single bundled plan.

Is it worth paying for all of them separately?

Honestly, sometimes. If you live in ChatGPT and rarely touch anything else, a single $20 plan may be all you need, and a dedicated app can have niche features a bundle does not match. Bundling wins the moment you regularly use two or more models, want image generation and search included, or are simply tired of juggling several bills and rate limits. If you are mainly thinking about leaving one tool, our ChatGPT alternative and Perplexity alternative guides walk through the trade-offs.

Frequently asked questions

How much does it cost to use all the AI models?

Subscribing to ChatGPT, Claude, Gemini, Perplexity, Grok, and Mistral separately costs about $125 a month, and more once you add dedicated image generation. A bundled app like MultiChats covers the same models from $20.99 a month.

Is it cheaper to buy one AI app or several?

One multi-model app is far cheaper if you use more than a single model. Six separate plans run about $125 a month (about $1,500 a year). One MultiChats Pro plan is $20.99 a month ($199.99 a year), saving around $1,250 a year.

What is the real cost of accessing every major LLM?

Realistically $125 to $160 a month if you pay each provider directly, and far more with premium tiers like ChatGPT Pro at $200 a month. The cost-effective route is a single subscription that aggregates the models, from $20.99 a month with MultiChats.

Does one subscription really include GPT-5 and Claude?

Yes. MultiChats includes GPT-5 and Claude Opus 4.6 alongside Gemini 3.1, Grok, Mistral, and 50+ other models, and you can switch between them inside a single conversation. There is more detail in our guide to chatting with GPT-5 and Claude in one place.

Is there a free way to try multiple AI models?

Yes. The free plan includes 5 AI models, limited daily messages, and 2 image generations per month, with no credit card required. It is an easy way to feel out whether a bundle fits before paying for anything.

The bottom line

Using every major AI model separately costs around $125 to $160 a month in 2026. If you genuinely use more than one, a single multi-model subscription is the cheapest way to get all of them, and it clears out the six bills, six rate limits, and six logins in the process. If that sounds like you, see the all-in-one price and compare it against what you pay today.
