Reviewer scorecard
“No developer API or platform to build on. It's a consumer entertainment product with no B2B play.”
“The gateway approach adds caching, fallbacks, and guardrails without code changes. Production AI apps need this layer.”
“Impressive engagement but no path to serious monetization. The safety concerns with younger users are a liability.”
“Reliability features — caching, retries, fallbacks — are table stakes for production AI. Portkey makes them easy.”
“Character.ai has the best understanding of long-context character consistency. That tech could be transformative if applied elsewhere.”
“AI gateways will be standard infrastructure. Portkey's focus on reliability and guardrails addresses real production needs.”
