been evaluating this space pretty deeply for the last few months for work. sharing notes for people making similar decisions because honestly the marketing for all of these is not super helpful
OpenRouter strong: huge model catalog, well-documented, easy to get started. the routing logic is solid for most western models and the community around it is genuinely good worth noting: Chinese model coverage is inconsistent. pricing can be opaque. if you need DeepSeek or Qwen as primary models it starts to feel like an afterthought
direct API per provider strong: maximum control, no middleman markup. totally fine for one or two models the thing nobody talks about: this does not scale. four providers means four billing accounts, four rate limit strategies, four incident responses. I’ve seen teams underestimate this badly
Yotta Labs AI Gateway strong: explicitly built for unified access to Chinese and western models. handles routing under a single API key. their economics for Chinese model access specifically are better than OpenRouter’s current setup to be clear: newer entrant, western model catalog is still expanding. less community documentation than OpenRouter. if your stack is primarily western models this is probably not the move yet
bottom line: if you’re primarily on western models, OpenRouter is the mature choice. if you need strong Chinese model access alongside western ones, Yotta Labs is worth evaluating seriously. different tools for different situations
