How to — estimate what an AI feature will cost before you ship it

You want one number you can defend in a planning meeting: what each completed job on your feature costs, and what a month of it costs at launch volume. This is a measurement job, not a guess — a morning with your real prompts beats any pricing page. 1. Run 20 real requests and keep the usage numbers. Not demo prompts — your actual system prompt, tool definitions, the documents you stuff into context, and a typical user message.

SpaceX reportedly seeks $40B, led by Apollo, to buy Nvidia chips

The compute boom found its lender, safety regulation found its loudest advocate, and the open-source world got a model that only picks answers. SpaceX is reportedly lining up $40 billion, led by Apollo, to buy Nvidia chips — and almost all of it is debt. The Financial Times broke the plan, citing people familiar with it; Reuters and Bloomberg have since relayed the report, and SpaceX, Apollo, Nvidia and Pimco have all declined to comment, so this is reported rather than confirmed.

AI 101 — What is a large language model?

A large language model (LLM) is a very big neural network trained on enormous amounts of text to do one job well: predict the next piece of a text, given everything that came before it — then tuned so that when you talk to it, it actually helps instead of rambling. ChatGPT, Claude, Gemini, Llama, DeepSeek: every chatbot in the news is an LLM, and most AI features in the software you already use have one quietly bolted inside. That prediction job sounds too simple to matter, and it is the whole…

Google's Suncatcher puts its first TPUs in orbit

Compute is leaving the ground — literally — while the people who build AI models keep warning about where the buildout ends. Three stories this hour. Google's first Suncatcher satellite is in orbit, and it is carrying the company's own TPUs. The prototype launched Thursday aboard a SpaceX Falcon 9 from Vandenberg on the Transporter-18 rideshare, tucked alongside Planet Labs satellites, and Google confirmed it has contact with the spacecraft and it is operating as expected.
