We recently started allowing candidates to use any AI tools during coding interviews. Today, we accidentally gave a data platform engineer a coding challenge meant for a full-stack engineer. It actually made the hire/no-hire signal much clearer.

this is the coolest demo I've seen a while, a must-watch for anyone interested in human-agent interaction!

I’ve always wondered why China open-sources so many LLMs. Then I realized they’re competing on energy. LLM inference turns electricity into intelligence, so the goal is to sell the cheapest intelligence via cloud inference. China is moving from manufacturing to intelligence.

@andybowu Feature request: grok custom shortcuts for tweet automation @nikitabier , would be happy to pay for this

Books in the future are likely all in the forms of https://t.co/WyQ4iWGWA5 or sth alike and sold only to agents.

@timtimtim_eth try the $200 codex, it’s waaaaay more generous and better than cc on long term reasoning.

[Rex @rexren_]

Wish every Codex agent instance had a shared message index so each one knows what the others are changing in real time, flags overlapping work, and I don’t have to manually sync 2–3 parallel agents coding.

AI作曲+真人演绎的MV究竟可以多颠
《无能为力》是我们在11月即将发表的最新AI剧场作品《我非我非我》Selfish Selfie的主打歌。由 @SunoMusic 作曲/编曲，这是一首把「无能为力」唱得理直气壮的 AI × 真人演绎的黑色小夜曲。面对不断变化的时代，我们选择在荒诞里松一口气，在嘲讽里保留温柔。全曲MV由@apple iPhone拍摄完成。“一镜到底”是不是很大胆(坏笑）。
如果MV看得不过瘾，想现场感受一下AI浓度超高的互动剧场究竟是怎么样的，那就11月14-16号走进剧场来感受一下吧！

It probably makes sense for @OpenAI to put the browser directly into the chatGPT mac app. Search bar is the entry point for the browser UX for most people.

This tweet is from OpenAI Atlas — ChatGPT built right into your browser.

Most of my early-stage product code can be built with @OpenAI Codex within a few shots. Next I think Codex/CC should start to understand my business goal and proactively suggest improvements across the codebase to unlock new biz opportunities — aiming for staff engineer+ quality.

3 out of 5 of my @OpenAI Sora prompt failed due to IP protection. You lost most of the fun if you can’t remix household name IPs. The existing IP protection is close by default, but we need a paradigm shift and make it open by default for the AI era. The smartest influencers on Sora are already doing that by making their cameo public to anyone.

@NicooSvane Are these two things actually causal? Why is Reddit “often” ranked at 11?
