BENEFITS OF USING A THIRD-PARTY CLIENT
Using Geeps can be a great alternative to a ChatGPT Plus or Pro subscription:
- you have faster and cheaper access to the latest models (they become available in the API sooner than in the free ChatGPT/Claude/Gemini tier)
- you pay only for the actual usage (i.e. input and output tokens) and this can be much lower than a premium subscription, let alone multiple subscriptions
- you have higher rate limits for model usage than a free ChatGPT user
- you can create multiple keys and share them with family or team while managing billing from a single account
- API prices become lower over time, allowing you to save even more
- with multiple provider support you can keep all your chats in a single app
- when using OpenRouter you can use many models for free!

PRIVACY
