Last year taught everyone a lesson: model providers change pricing, throttle, and occasionally ban — often with little warning. If your code is hard-wired to one provider's key, every change is a rewrite.
A cleaner pattern is an aggregation layer: one OpenAI-compatible key, 31 models (DeepSeek, Qwen, GLM, Kimi…) behind a single /v1 endpoint. Switch models by changing one parameter — no code or key changes. And when upstreams spike during peak hours (DeepSeek recently went 4.5× during peak), the flat rate absorbs the hit, so your bill stays predictable.
