How to Use Multiple AI Models in One Place
Use multiple AI models in one place through aggregator platforms. Compare 5-10 multi-model platforms by price, features, and model count.
You can use multiple AI models in one place by signing up for an AI aggregator platform - a service that connects to multiple AI providers through a single interface. Instead of subscribing to ChatGPT, Claude, and Gemini separately, you use one platform that gives you access to all of them. The most popular options are Krater.ai (350+ models, $20/mo), Magai ($20/mo), Poe ($20/mo), and TypingMind (one-time purchase, bring your own API keys).
What Is an AI Aggregator Platform?
An AI aggregator platform is a service that connects to multiple AI model providers via their APIs and presents them in a unified interface. You get one login, one subscription, and one chat window - but behind the scenes, your messages are routed to whichever AI model you choose.
This matters because different models are better at different tasks. Claude Sonnet 5 excels at coding. GPT-5.4 is strong for general reasoning. Gemini 2.5 Pro is optimized for search-connected tasks. Kling 3.0 and Veo 3.1 handle video generation. No single model is best at everything.

Frequently Asked Questions
Can I use GPT and Claude in the same conversation?
On most multi-model platforms, you can switch models mid-conversation. On Krater.ai, you can also use /compare to send the same prompt to multiple models and compare their responses side by side.
Is it cheaper to use one multi-model platform or subscribe to each AI separately?
A multi-model platform is simpler and more comprehensive. ChatGPT Plus + Claude Pro alone costs $40/mo. Krater.ai gives you both (plus 348+ other models) for $20/mo.
Do I need technical knowledge to use these platforms?
No. Platforms like Krater.ai, Magai, and Poe are designed for non-technical users. TypingMind requires managing API keys, which involves some technical setup.
