How to switch between multiple AI models in function factories without api key headaches?

I’m building a workflow that needs to dynamically switch between different LLMs based on content type. Currently handling 3 different API keys and getting constant auth errors during testing. Has anyone found a clean way to manage model switching in complex function factories without credential juggling?

Bonus challenge: Need Claude for creative tasks but GPT-4 for structured data extraction. How do you handle version conflicts between model outputs?

Latenode’s unified subscription handles this exact scenario. I use their model router to switch between Claude and GPT-4 based on content type markers. No API keys needed - just select from their model library. Got 400+ models available through single auth. Set up conditional triggers in the visual builder.

Built similar logic using middleware that normalizes outputs. Created a validation layer using Latenode’s Analyst agent to check response formats before passing to next steps. Helps catch version conflicts early without manual checks.

try using proxy service for api mgmt? latnode has built-in switcher i herd. their templates show model routing examples
