Best for	Developers and teams building AI features Startups shipping products on frontier models Builders needing text, vision, and audio in one API	Developers building multi-model apps Teams comparing models Agent builders needing routing
Pros	One API for text, image, audio, and embeddings Frontier models with mature SDKs and documentation Higher-level tools: function calling, structured outputs, Realtime, fine-tuning Playground and usage dashboards make it fast to start and monitor Usage-based pricing scales from hobby projects to production	One API for hundreds of models Automatic fallbacks improve resilience Price and latency routing Consolidated billing across providers Transparent per-model pricing and usage rankings
Cons	Model names and per-token prices change frequently Usage-based cost can be hard to forecast at scale Building directly on one vendor can create lock-in No flat free plan; trial credits are limited and not guaranteed Rate limits and some features gated by usage tier	Adds a middleman to your inference path Roughly 5% markup over upstream prices Latency depends on upstream providers You route keys and traffic through a third party Going direct can be cheaper for a single high-volume model
