Token costs fell 280x. Enterprise AI bills up 483%. OpenAI lost $5B in 2024, heading toward $14B in 2026. They're spending $1.69 for every dollar they earn. The cheap tokens you're buying today are being subsidized by their balance sheet. Tokenomics. #AI #Inference

My job is building AI infra at scale. The constraint isn't chips. It's thermal. Modern GPU racks: 132kW. Next-gen: 240kW. Most data centers are air-cooled and can't cope. Liquid-cooled facilities are rare. $650B is being bet on fixing that. #AIInfrastructure

800,000 human neurons in a dish, learning to play Doom. Not simulated — biological cells adapting in real time. The human brain has tens of billions of neurons and learns a new game in minutes. Reminder of what we're trying to replicate. #AI #Neuroscience linkedin.com/feed/update/ur…

Does it hit the corner though?

GPT-5.4 ships with Computer Use and Excel plugins. Pro-AI, pro-agents. But there is a real gap between AI for personal use and AI inside a legal entity in the business of trust. Tools moving faster than governance. linkedin.com/feed/update/ur…

Microsoft's Phi-4 is designed to know when reasoning is worth the compute and when it's overkill. That's a more useful production design than just thinking harder on everything. linkedin.com/feed/update/ur… #LLM #AIInfrastructure #Inference

OpenAI is building a GitHub competitor, reportedly triggered by recent GitHub outages. The real story isn't git hosting. It's what happens when your AI inference layer starts absorbing your entire dev stack. linkedin.com/feed/update/ur… #SDLC #DeveloperTools #AI

Ran it locally on an RTX 5080 laptop — with thinking vs without 👇

Alibaba's Qwen3.5-9B outperformed OpenAI's 120B model on benchmarks — runs on a laptop under Apache 2.0. When a 9B model beats something 13x bigger, your inference cost math needs a rerun. linkedin.com/feed/update/ur… #AIInfrastructure #OpenSource #LLM

"We've built a new policy layer to guard against misuse." – Anthropic's latest statement on their "Department of War" initiative. Bold move toward safer AI, but the real question is: how far will that go in practice? anthropic.com/news/statement… #AIethics #ResponsibleAI #Anthropic

Ever wonder how a firm can reverse-engineer its own neural net? 🤔 Jane Street shared a clean technical walk-through showing how to build a model you understand, then debug it. 👉 blog.janestreet.com/can-you-revers… #MachineLearning #AI #DataScience

Stopped to take a photo of the beautiful sunset and it became an unintended advert for @FordMustang

@MKBHD I for one welcome our new atlas robots overlords.

Boston Dynamic just unveiled their newest Atlas robot. This is not a render. Oh my god It's giving "call an ambulance... but not for me" youtu.be/29ECwExc-_M?si…

@politta_c I volunteer as a tribute.

Nós, fãs que ficamos acordados para assistir a corrida, pedimos encarecidamente para todos que não assistiram a corrida de madruga, por favor, não assistam as próximas duas corridas. Não podemos mapear quem é o pé frio, então todos vão ter que auxiliar nessa tarefa. Att.

Hey ⁦@Reuters⁩… maybe you used the picture of the wrong Luis Suarez?

@benbravo73 To be honest I wish there was thing that would run a check everywhere.

@rettori Yes. And I'm doing it with tweets and LinkedIn posts as well 😜

Are you all also looking at the change history of documents to see if they were ‘organically’ written, or someone just dropped the ChatGPT content?
