Cons

The Claude API ecosystem is smaller than OpenAI's — fewer community libraries, fewer tutorials, and less Stack Overflow coverage+152
Rate limits on lower-tier API keys are more restrictive than OpenAI's and can block production features during traffic spikes+134
Model naming changes (Opus, Sonnet, Haiku) and versioning have been confusing — it's not always obvious which model to use for a given quality/cost tradeoff+98
The API doesn't support fine-tuning or custom model training which limits use cases where domain-specific behavior is critical+81
