Been looking for something exactly like this. Swapping between OpenAI, Anthropic and Gemini APIs gets old fast. The Smart Routing idea is especially interesting since it's one of those things every team eventually ends up building themselves. Definitely going to test it in one of my side projects.
🚀 Since launch we've shipped Smart Routing.
Apiarium can now automatically choose the best model for each request based on quality, speed and cost.
The goal is simple:
• lower API costs
• better performance
• zero code changes
More infrastructure features are coming soon.
