Models
Learn how to select, compare, and understand different AI models inside MomentumAI.
MomentumAI connects you to the world's leading AI models – including GPT, Claude, Gemini, and Mistral. We're model-agnostic, meaning you can choose whichever model best fits your task instead of being locked into one provider.
In a world of AI hype and noise, we believe in transparency and honesty. Every model in MomentumAI comes with clear, comparable ratings based on independent research – so you can make informed decisions grounded in real performance, not just promises.
How to Read Model Cards
When you browse models in the picker, each model shows a card with ratings across six key dimensions. These ratings help you compare models without being an AI expert – they highlight different strengths and trade-offs for day-to-day work.
All ratings use a 5-star system where more stars is always better. We keep the scale consistent so you can compare models at a glance.
For detailed explanations of each rating, see Understanding Model Ratings below.
