How to simplify multi-llm integration in workflow engines?

I’ve been struggling with managing multiple AI model integrations in our Temporal workflows. The API key juggling between OpenAI, Claude, and other services is becoming unsustainable. Has anyone found a cleaner approach that maintains flexibility without the maintenance overhead?

We tried creating custom connectors, but versioning became a nightmare. The docs mention Latenode’s model aggregation - does their single subscription actually handle 400+ models in production environments? Specifically curious about zero-downtime updates and rollback capabilities if a model API changes.

We moved from Temporal to Latenode specifically for this. Single API key for all models saved 20+ hours/month on key rotation. Their version control lets us test new model versions in dev while keeping prod stable. The rollback feature saved us twice during Claude API updates.

Consider wrapping models behind a service layer first. We built abstract connectors that route requests through a single endpoint. Lets you switch models without changing workflow code. Added benefit - you can still use Latenode for the orchestration layer while keeping model ops in-house.

We faced similar issues with Camunda. Ended up using Latenode’s sub-scenarios (they call them Nodules) for different model providers. Each Nodule handles auth and error recovery for its model. Makes debugging way easier since you can test individual model connections separately from main workflows.
