Audited financials obtained by journalist Ed Zitron show OpenAI's revenue grew from $3.7B in 2024 to $13.07B in 2025 — but its loss from operations ballooned from $8.78B to $20.92B over the same span. R&D alone hit $19.18B in 2025, outpacing total revenue, though efficiency improved from spending $2.37 to $1.60 per dollar earned. The numbers land awkwardly against the company's pitch to investors that it'll be profitable by 2030.

The Trump administration has paused adding DeepSeek, memory chipmaker CXMT, and 100-plus other Chinese firms to the Commerce Department's Entity List, a diplomatic move to avoid escalating tensions with Beijing. An interagency committee had approved the companies last year over national-security concerns, including allegations DeepSeek supported Chinese military and intelligence work. Anthropic and OpenAI have both said DeepSeek targeted their models to extract capabilities.

Researcher Jacky Liang dropped 11 LLMs into a 2D battle-royale game and found Grok 4.1 Fast won 43% of matches at just $0.97 per win, dramatically outperforming Claude Sonnet 4.6 at $26.78 per win despite weaker benchmark scores. The takeaway: "alignment tax" from safety training made cooperative models worse at combat, while less-filtered models executed aggressive strategy. It's a sharp reminder that standardized benchmarks can badly mislead real-world model selection.

CADAM is an open-source web app that turns natural-language descriptions and images into 3D CAD models using AI, running entirely in the browser via WebAssembly and OpenSCAD. It generates parametric designs exportable as STL, SCAD, or DXF, with interactive dimension controls and support for libraries like BOSL and MCAD. It's aimed at both hobbyist makers and working engineers.

Lore is a centralized, content-addressed version control system from Epic Games, built to handle massive projects mixing code with large binary assets. It uses Merkle-tree storage, on-demand file hydration for lightweight workspaces, and chunked storage that cuts duplication across branches and history. It's MIT-licensed and fully open source.

Browser Use runs Firecracker microVMs on standard EC2 instances rather than bare-metal, accepting nested-virtualization overhead in exchange for faster scaling and lower cost. They resume VMs from snapshots using large memory pages, custom page-fault handling, and real-time CPU prioritization to absorb the Chromium launch burst. The result: browser sessions starting at 825ms median latency for about $0.02 per hour.

Scientific American reports the US research enterprise facing unprecedented disruption from federal funding cuts, political interference, and an exodus of scientists. DOGE and administration cuts have frozen or canceled thousands of grants worth roughly $1.4B, closing labs, with 75% of surveyed scientists weighing leaving the country. Bans on topics like DEI research mark a new form of government censorship that authors say has broken the postwar science-government compact.

Ribbie renders live baseball pitch-by-pitch in cozy 8-bit pixel art, showing score, inning, count, outs, bases, pitcher, and batter at a glance. It's free, needs no account, and offers a calmer way to follow a game without a full broadcast or a stats deep-dive. A nice slice of indie web craft riding the front page.

Kevin Burke argues regulatory constraints keep Walnut Creek from building Copenhagen-style family apartments, citing parking minimums, mandatory dual stairways, costly elevators, and height limits. He makes the case that single-stair reform could unlock denser, more affordable housing with better natural light and amenities like playgrounds. A policy-and-construction read that resonates with the HN housing crowd.

Storied Colors is an ongoing index of 252 pigments documenting the chemistry, provenance, and often-grim human history behind named colors. It publishes one color a day, each with first-documentation date, composition, geographic origin, and the people who, as the site puts it, "paid for it in poison." A quietly beautiful piece of web archival craft.
