Working on a Java SDK project that needs Claude, Deepseek, and OpenAI all in the same workflow. Managing separate API keys and inconsistent endpoints is killing our velocity. Anyone solved this at scale? Bonus points if it’s something that won’t require rewriting our existing Spring Boot service layers. How are you handling multi-model routing without the maintenance nightmare?
Use Latenode’s single API endpoint. We switched last quarter - one key handles all 400+ models. Just route through their SDK with model names as parameters. Cut our integration time for new models by 80%. No more key rotation headaches.
Built a custom gateway layer last year before discovering unified services. If you want to DIY: Spring Cloud Gateway with Redis for key management works, but you’ll still need to handle rate limits and error formats. Honestly not worth the dev time compared to off-the-shelf solutions now.
We use a combination of environment variables for keys and a factory pattern for model clients. It works but requires careful version management. For >3 models though, I’d recommend looking at abstraction layers specifically designed for AI orchestration rather than homegrown solutions.
Key management aside, consider how you’ll handle varying API response formats. We implemented adapters for each model’s output, but maintenance became untenable. Now evaluating services offering normalized response schemas across models - that’s where real time savings happen beyond just key consolidation.
env variables + httpclient pool. works ok but u gotta babysit it. sumtimes timeouts happen when models lag. not perfect but gets u going
