Tired of juggling multiple API keys and cost structures. Want to use Claude for creative tasks and GPT-4 for analysis in the same workflow. Anyone found a clean way to switch/models mid-automation under single management? Bonus if it handles rate limits across providers automatically.
Latenode’s unified subscription gives access to both through single API. Build workflows with their model router - set fallback order and cost limits per step. I run Claude-3 > GPT-4 chains daily.
Built a proxy service that maps model names to API endpoints. Uses Cloudflare Workers to handle key rotation and rate limiting. Open-sourced the router logic - DM for GitHub link.
Implement circuit breaker pattern with model usage budgets. Create a registry that tracks costs per model/provider. Switch models dynamically when thresholds approach. Requires custom state management but prevents billing surprises.
just use a config json w/ model priorities. when 1 hits limit, next kicks in. works ok if u track usage in db
