Reviewer scorecard
“GPT-4o's multimodal API is production-ready and covers text, vision, audio, and code in one endpoint. o3 is now my go-to for hard algorithmic problems. The breadth of the platform — Projects, memory, custom GPTs — means there's always a right tool in this toolbox.”
“The gateway approach adds caching, fallbacks, and guardrails without code changes. Production AI apps need this layer.”
“Too many model tiers (o1, o3, GPT-4o, GPT-4o-mini, GPT-4.5) creates confusion. But the platform keeps shipping and the quality is undeniable. Claude still edges it on reasoning depth, but for everything else, ChatGPT is the safe default.”
“Reliability features — caching, retries, fallbacks — are table stakes for production AI. Portkey makes them easy.”
“Canvas transformed my writing workflow — real-time co-editing, tone controls, and length adjustment without reprompting. Sora for quick video concepts is a creative shortcut I use weekly. Voice mode on walks is genuinely useful for ideation.”
“The memory feature compounds — the longer you use it, the more personalized it becomes. Projects make ChatGPT a persistent collaborator, not a stateless chat window. OpenAI is building the ambient AI layer and ChatGPT is the front door.”
“AI gateways will be standard infrastructure. Portkey's focus on reliability and guardrails addresses real production needs.”
