Reviewer scorecard
“The serverless standard. Event sources, layers, and container image support cover every use case.”
“The most mature AI developer platform. Assistants API, function calling, and the Playground are all well-designed. Documentation is extensive.”
“Cold starts have improved dramatically. For event-driven workloads, Lambda's pricing model is unbeatable.”
“Reliability has improved dramatically. The rate limits are generous on paid tiers. The Assistants API is finally stable enough for production.”
“Serverless is the default compute model. Lambda's ecosystem and AWS integration ensure its dominance.”
“OpenAI has the largest ecosystem of developers and integrations. Even if other models catch up, the platform moat is real.”
