SpaceX acquires Cursor for $60 billion in all-stock deal

(5 newsletters)

Days after its record-setting IPO, SpaceX exercised an option first announced in April to buy AI coding startup Cursor for $60 billion in stock, with the post-listing rally nearly doubling SpaceX’s value and pushing Elon Musk’s personal wealth past $1 trillion. Cursor, which crossed $1 billion in annualized revenue in November, is already part of a joint model-training effort with Grok Build, and CEO Michael Truell teased an upcoming model that will be “generally intelligent” and as large as Opus. The deal is expected to close in Q3 pending regulatory approval, and Cursor also launched Origin, a GitHub competitor, plus an iOS app.


Security experts push back on the U.S. ban of Anthropic’s top models

(5 newsletters)

More than 150 researchers and executives (76 of them named cybersecurity veterans) signed an open letter urging Washington to reverse export controls on Claude Fable and Mythos, arguing that stripping defenders of the strongest bug-hunting tools only helps attackers, especially since the triggering vulnerability can be replicated on rival models like GPT-5.5 and Anthropic’s own Opus. Anthropic and Trump administration officials are reportedly in active talks to restore access, while the administration rejected UK PM Keir Starmer’s request to exempt G7 allies from the ban. Commentary ranged from “the window has closed” reflections on Mythos to Stratechery’s framing of the episode as Anthropic’s “safety superpower.”


Meta’s AI unit faces a morale and engineering crisis

(3 newsletters)

CTO Andrew Bosworth pledged a culture reset in a leaked memo, admitting Meta “did an atrocious job explaining the vision” of an AI reorg that forced thousands of employees into model-support work, with one worker branding the unit “the gulag.” Promised fixes include manager report caps, less internal shuffling, social events, and better office kitchens, concessions that critics say may further alienate staff. A widely shared Pragmatic Engineer deep dive argues the broader changes are dismantling Meta’s once-celebrated high-performance engineering culture.


The real AI coding bottleneck is review, not writing

(4 newsletters)

A theme ran across the developer newsletters: AI makes code cheap to generate but expensive to trust. A 22,000-developer Faros study found code churn up 861%, per-developer defect rate up from 9% to 54%, review duration up 441%, and zero-review merges up 31%, while senior engineers report losing up to a third of their week cleaning up machine-generated output. The prescribed response is more engineering discipline, not less: spec-driven development (write the spec, then let the agent build against it) and treating review as the most leveraged skill in software.


Leaked docs show OpenAI lost $38.5 billion in 2025

(2 newsletters)

Independently verified audited financials show OpenAI’s net loss ballooned to $38.5 billion in 2025, more than seven times its 2024 loss, even as revenue grew from $3.7 billion to roughly $13 billion. The disclosure landed the same week the company filed confidentially to go public and as a separate report showed ChatGPT’s market share slipping below 50% for the first time amid competition from Gemini, Claude, and Grok.


Microsoft’s Copilot Cowork goes generally available

(2 newsletters)

Microsoft rolled out Copilot Cowork, its agentic task-running tool, to any Microsoft 365 user worldwide with usage-based pricing, claiming it runs 30 to 40% cheaper per prompt than Anthropic’s Claude Cowork. Databricks countered the same day with Genie One, an agentic coworker grounded in a company’s own data via its Genie Ontology context layer.


Z AI’s GLM-5.2 brings open weights near the frontier

(2 newsletters)

Chinese lab Z AI released GLM-5.2, an MIT-licensed open-weights model with a 1M-token context window that surpasses GPT-5.5 on real-world coding, reasoning, and math benchmarks and scores just below Opus 4.8, at a fraction of frontier pricing. It reportedly topped Claude Fable 5 on the Code Arena leaderboard, making it one of the strongest models available for coding and site building.
