AI News | Field Notes by Michael Nemtsev
A pyramid inverted under crushing weight, with corporate monoliths pressing down while tiny figures with coding tools scatter outward at the base, symbolizing capital concentration squeezing smaller players in AI.

The pattern across the day was simple: power and money are concentrating fast at the top of the AI stack while everything below is being squeezed for cash. Microsoft and OpenAI dissolved their cloud exclusivity, a London lab with no product raised $1.1 billion on a researcher's name, and DeepSeek shipped a frontier-class open model that runs on Chinese chips. Meanwhile Meta and Microsoft cut more than 20,000 jobs to help fund $700 billion in capex, and a data center developer is borrowing $4.5 billion in junk bonds against future demand. If you build software, the week to revisit your coding tools and your agent harness is this one. If you don't, this is a good week to ask your manager what work in your role is being measured for automation, before someone else does it for you.

Microsoft and OpenAI rewrite their vows

AnalysisOn April 27, Microsoft and OpenAI announced an amended partnership that ends Microsoft's exclusive right to sell OpenAI's models on its cloud. Microsoft keeps a non-exclusive license to OpenAI's intellectual property through 2032 and stops paying OpenAI a revenue share. OpenAI keeps paying Microsoft a 20% revenue share through 2030, now capped, no longer tied to a declared moment of artificial general intelligence (AGI, an AI system rivaling human capability). The deal clears the path for OpenAI's separate $50 billion arrangement with Amazon, where Andy Jassy says OpenAI models will arrive on AWS Bedrock in the coming weeks. Microsoft remains a roughly 27% shareholder in OpenAI's for-profit arm, valued near $135 billion. The AGI escape hatch that hung over investors is gone, and so is OpenAI's cloud monogamy.

A $5 billion bet on a London lab with no product

AnalysisIneffable Intelligence, a London AI lab founded in November 2025 by former DeepMind reinforcement learning lead David Silver, came out of stealth on April 27 with a $1.1 billion seed round at a $5.1 billion valuation. Sequoia and Lightspeed co-led, with Nvidia (reportedly $250 million), Google, DST Global, Index, and the UK Sovereign AI Fund piling in. The pitch: a superlearner that learns from its own experience using reinforcement learning (training by trial and error rather than reading human text). There is no product, no revenue, no roadmap. The round is the largest seed in European history, larger than what most companies raise across an entire decade, and it lands in the same month that Mira Murati's Thinking Machines closed $2 billion at $12 billion. Founder pedigree is now the asset class.

Cursor decides the IDE was the wrong abstraction

AnalysisAnysphere's Cursor 3, codenamed Glass, treats the integrated development environment (the editor where developers write code) as a fallback. The new default is an Agents Window where humans manage parallel agents that read multiple repositories, hand off between local and cloud, and ship pull requests while the engineer watches. The shift is commercial, not philosophical. Cursor's annualized revenue ran at $2 billion in February, but Anthropic's terminal-first Claude Code reached $2.5 billion with over 300,000 business customers. Hacker News reports of one user spending $2,000 a week on Cursor before switching to Claude Code Max for roughly a tenth the cost suggest that how a tool packages context can swing the bill by an order of magnitude. Wikipedia is also reporting an optional $60 billion SpaceX/xAI offer to acquire Anysphere. Code editors as we knew them are getting demoted.

Humanoids quietly cross from demo videos to factory orders

AnalysisShanghai-based Robot Era closed a Series C of more than $200 million on April 27, led by logistics giant SF Express, just six weeks after a $146 million Series B that put the company above a $1.4 billion valuation. Total raised is now around $346 million. Sereact added a $110 million Series B for industrial robotics brains the same day. Robot Era's Tsinghua-incubated L7 humanoid has reportedly attracted over $70 million in commercial orders, the kind of number that distinguishes a working product from a CES dance routine. Behind the headline funding, the structural shift is who is buying. Logistics operators and automakers, not venture funds, are now writing the checks because they need bodies that work three shifts. Goldman Sachs already noted humanoid manufacturing costs fell 40% from 2023 to 2024.

AI Agents ·OpenAI release notes

Sales reps now build their own coworkers

AnalysisOpenAI is rolling out Workspace agents in research preview to ChatGPT Business, Enterprise, Edu, and Teachers plans, free until May 6 before credit-based pricing starts. The example case: a Rippling sales consultant built and iterated a Sales Opportunity agent end to end, with no engineering team, that researches accounts, summarizes Gong call recordings, and drops deal briefs into Slack. Tasks that previously consumed five to six hours a week per rep now run in the background. Workspace agents complement Codex (now powered by GPT-5.5) and the recently expanded ChatGPT integrations with Box, Notion, Linear, and Dropbox that added write capabilities. The throughline: the line between a power user spreadsheet and an autonomous coworker is dissolving, and OpenAI is racing Anthropic's Claude Cowork to own the space where every salaried employee builds agents in plain English.
