Cheapest Way to Use GPT-5, Claude and Gemini Together

The cheapest way to use GPT-5, Claude, and Gemini together is to stop buying three subscriptions and use one app that includes all three. MultiChats gives you GPT-5, Claude Opus 4.6, and Gemini 3.1 (plus 47 more models) for $20.99 a month, versus roughly $60 a month for the three plans bought separately. That is about a third of the price, and you can switch between the models in the same conversation.

If you only ever use one model, a single subscription is fine and you can stop reading here. But if you want the strongest answer for each task (Claude for long writing, GPT-5 for reasoning, Gemini for fast everyday questions), paying three separate bills is the expensive way to do it. Here is the math, and the cheaper path.

What each one costs separately

The three flagship chat apps each charge roughly $20 a month for their paid consumer tier. None of them includes the others. Buy ChatGPT Plus and you get OpenAI models only. Buy Claude Pro and you get Anthropic only. Gemini AI Pro is Google only, and it tends to be bundled into Google One, which makes the true cost harder to read on your statement.

So the realistic cost of having GPT-5, Claude, and Gemini at the same time is around $60 a month, or roughly $720 a year. That is before you count the friction of three apps, three histories, and three sets of usage limits to keep track of.

The bundle math: one subscription versus three

MultiChats puts GPT-5, Claude, and Gemini behind a single subscription. Pro is $20.99 a month, or $199.99 a year if you pay annually (about $16.67 a month, saving you roughly $52 over twelve monthly payments). Compared with around $60 a month for three separate plans, that is close to $470 saved in a year, and you still get 47 other models on top.

The savings are real, but the bigger win for most people is that the three models live in one place. You can ask GPT-5 a question, decide Claude would write the email better, and switch models mid-conversation without copy-pasting context between tabs. There are no silent downgrades to a weaker model when you hit a limit, which is a common complaint with single-vendor apps.

Three flagship models, one bill, roughly a third of the price, plus dozens of other models you would otherwise never pay to try.

Pricing table: monthly versus annual

Here is how the MultiChats plans compare. Pro covers almost everyone who wants GPT-5, Claude, and Gemini together. Pro+ adds the extras you only need if you do heavy image or video work.

The free tier is a genuine way to test the idea before you pay. It includes 5 free models (GPT-5.4 Nano, Gemini 3.1 Flash Lite, Mistral Small 3.2, and more), limited daily messages, and 2 image generations a month. Memories, folders, web search, URL reading, and voice are Pro features, so the free tier is best treated as a trial rather than a full replacement.

What else you get beyond the three models

Saving money is the headline, but the practical day-to-day benefit is everything that ships alongside the models. On a Pro plan you get:

• Mid-conversation model switching, so one thread can move between GPT-5, Claude, and Gemini without losing context.

• Inline image generation and on-demand image creation right inside the chat.

• Real-time web search and URL reading, so you can ask about current events or paste a link and have the model read the page.

• Saved memories, per-folder customization, and folders to keep work, study, and personal chats organized.

• Voice messages and voice calls on mobile, plus private per-chat notes on web.

• No ads, no training on your data, and no vendor lock-in.

Because every model shares one usage pool, the limits are transparent and predictable instead of three separate quotas that each reset on their own schedule. If you have been juggling tabs, this is the part that quietly saves the most time.

When one subscription is actually enough

To be fair, not everyone needs all three. If you live inside the Google ecosystem and mostly want quick answers tied to Gmail and Docs, Gemini alone may serve you well. If you write code all day and have settled on one model, a single plan is simpler. The case for a bundle gets strong when you find yourself wishing you could compare answers, or when you keep paying for a second tool you only use occasionally. If that sounds like you, the ChatGPT vs Claude vs Gemini comparison is a useful next read, and you may also want a ChatGPT alternative that does not lock you to one vendor.

Frequently asked questions

Do I need three subscriptions to use GPT-5, Claude, and Gemini?

No. MultiChats includes all three on one plan starting at $20.99 a month, alongside 47 other models. You can use each one and switch between them in the same conversation.

What is the cheapest plan with all three?

MultiChats Pro at $20.99 a month, or $199.99 a year (about $16.67 a month), includes GPT-5, Claude Opus 4.6, and Gemini 3.1 plus 47 more models. Buying the three apps separately runs about $60 a month.

Is there a free way to try GPT-5, Claude, and Gemini together?

The MultiChats free tier gives you 5 free models, limited daily messages, and 2 image generations a month. It is a good way to see how multi-model chat feels before upgrading to Pro for the full lineup.

Will I get the same models I would get from ChatGPT, Claude, and Gemini directly?

You get the flagship models from each provider in one app, and there are no silent downgrades to weaker models when you hit a limit. Exact model availability evolves as providers release new versions, which is part of the appeal of a single app that keeps the lineup current for you.

Can I switch between the models in one chat?

Yes. You can change models mid-conversation, so a single thread can start with GPT-5, get a second opinion from Claude, and finish with Gemini without losing context.

The bottom line

Three models, one bill, roughly a third of the price, with dozens of other models thrown in. If that math makes sense for how you work, you can see the plans and start free, or just open the MultiChats home page and try a few models before you decide. No pressure, and the free tier is there to help you figure out if it fits.
