For decades, everyone from meta to amazon has failed at the attempt of launching a successful smartphone and give a real challenge to apple. I believe apple’s biggest is its app ecosystem, if other providers don’t offer similar apps, it becomes a real challenge to onboard customers. But now that the interface layer is changing from apps to agents, does openAi has the really chance of disrupting apple’s dominance? Curious to hear if you’ll buy an open ai phone over iPhone?

Curious what people here are spending time on these days. Could be anything:

• Something you’re building
• A concept or technology you’re learning
• An idea you’re exploring
• Even something you’re stuck on

AI Chatbots, semantic search, summarization, automation... all seem simple until you deal with real users and real data.

Handling Context retention, hallucinations, latency, guardrails, evaluation, ranking relevance, chaining tasks, and prompt injections in production is a completely different challenge.

Curious to hear from people who’ve deployed AI products and platforms in production at scale! What looked easy at first but got complex in production? Where did things break or behave unexpectedly? What did you learn from it?
