What to watch for on the bill
- Rate-limit and quota tiers are opaque, limits are not always clearly stated, generating developer frustration
- Premium pricing at the Opus/Fable tier is high versus commodity LLM APIs
- Some features are gated by model tier or unavailable on certain third-party platforms (e.g. no Batches/web search on Bedrock)
