I used to juggle a dozen API keys for different AI models, but now I just use one that works with all of them. It's a simple change that saved me from a lot of configuration headaches and reduced the risk of accidentally exposing multiple keys. Now I can switch between GPT-4, Claude, and Llama without changing my authentication setup. It's honestly one of those quality-of-life improvements that makes working with multiple models feel seamless.
