Want to chat with the best AI models from OpenAI, Claude, and Google without paying $20/month? I'll show you how to use API keys with TypingMind to access top models for a fraction of the cost, demonstrate its killer feature of chatting with multiple models side-by-side, and explain when paying for a subscription is actually the smarter choice.

OpenAI: https://platform.openai.com/api-keys
Claude: https://console.anthropic.com/settings/keys
