Reviewer scorecard
“Claude on Bedrock with VPC endpoints and IAM auth is the enterprise standard. Knowledge Bases for RAG are production-ready.”
“The most mature AI developer platform. Assistants API, function calling, and the Playground are all well-designed. Documentation is extensive.”
“If you're on AWS, Bedrock is the obvious choice. Cross-model compatibility and guardrails reduce risk.”
“Reliability has improved dramatically. The rate limits are generous on paid tiers. The Assistants API is finally stable enough for production.”
“AWS's distribution advantage means Bedrock will be how most enterprises consume AI models.”
“OpenAI has the largest ecosystem of developers and integrations. Even if other models catch up, the platform moat is real.”
