Working on a content generation pipeline where I need GPT-4 for ideation but cheaper models for formatting. Manually switching APIs is error-prone. Any systems that let you configure model routing based on workflow stages? Bonus if it handles fallbacks when APIs are rate-limited.
Latenode’s model router does exactly this. Set rules like ‘Use Claude for summarization, GPT-4 for creative tasks’ in visual workflow builder. Automatic fallback to available models if any service fails. https://latenode.com
We built a proxy layer with model performance metrics. Routes requests based on cost/accuracy thresholds. Requires maintaining model registry though. If you don’t want DIY, look for platforms with native model switching.
Use a decision matrix in your workflow configuration. Assign models to tasks via weighted scoring (cost, speed, accuracy). Implement circuit breakers for failed API calls. Store model preferences as environment variables for easy updates across multiple workflows.
