Stop Paying for AI APIs: Here’s What You’re Missing

If you’re still paying for AI API keys, you might be wasting money.
I used to do the same, paying monthly fees for something that’s now free elsewhere.

Here are 3 platforms that give you powerful AI access for free, no credit card needed:

1. Google AI Studio
Think of it as Google’s AI playground.
You sign up in minutes and get an API key that works with top-tier models like Gemini 2.5.
No rate limits (within reason), no billing surprises. It’s perfect for testing ideas, building prototypes, or even launching small-scale apps for free.

2. OpenRouter
This one’s like an AI buffet.
With one account, you get access to 50+ models, including DeepSeek, Qwen, and Kimi.
What makes it great:

No need to manage multiple keys

Easy model switching

Ideal for comparing outputs and performance

Perfect if you’re experimenting or just want variety without the hassle.

3. Groq
Speed is the name of the game here.
Groq gives you lightning-fast inference for smaller models like Llama, Mistral, and DeepSeek.
I built a chatbot with it for a friend’s site. Zero lag, instant responses, smooth experience.

Great for anyone who wants low-latency AI for real-time apps.
