The current pace of token-efficient reasoning improvements across minor Claude Opus/GPT model versions is pretty wild. All signs point to this continuing. 4.6 to 4.7 could've been presented as a fairly large model bump in the past with this plot.

Why it worked

Short enough to read in full without expanding, which removes a step before the point lands.
Short sentences keep the pace up, so the reader never has to re-read a line.

The mechanics

Hook: Plain observation
Structure: Hook → Landing
Style: Conversational paragraphs at a steady pace.
Tone: plain, matter-of-fact
Written for: People building with AI

Disney has cancelled their deal with OpenAI. They planned to invest $1 billion into the company and let Sora have access to AI generate videos of characters from Disney, Marvel, Pixar and Star Wars. (Source: t.co

At my direction, early this morning federal agents arrested Don Lemon, Trahern Jeen Crews, Georgia Fort, and Jamael Lydell Lundy, in connection with the coordinated attack on Cities Church in St. Paul, Minnesota. More details soon.

For those confused why the US state and Silicon Valley are having a meltdown on twitter today. China released multiple AI models that are 50x more efficient than the best American AI models and made them open source, ruining the AI market

Universal HIGH INCOME via checks issued by the Federal government is the best way to deal with unemployment caused by AI. AI/robotics will produce goods & services far in excess of the increase in the money supply, so there will not be inflation.

I am very excited about AI, but to go off-script for a minute: I built an app with Codex last week. It was very fun. Then I started asking it for ideas for new features and at least a couple of them were better than I was thinking of. I felt a little useless and it was sad.

Hi! I'm one of the prompt writers that worked on this ad. It's a lot harder than people think! Prompts that my team used include: -make it funny -make it epic AND funny -funnier!!! Please be nice to my team as many of them will be laid off/replaced by AI

More from Nathan Lambert

Major restructuring at Gemini (Dean out, Hassabis no longer CEO). This story will be studied forever as the incumbant with all the advantages not being able to get going. P.s. OpenAI accomplished their original goal.

I read the Anthropic open-weight model piece and despite there being nothing new in it, it was a reasonable repeat of their positions, this site will collectively lose their minds for the next 12 hours. p.s. banning distillation is still dumb.

Kimi K3 license. It's inspired by MIT but distinctly non-commercial, where any company making over $20M/yr must get a specific commercial deal (and display Kimi K3 if over 100M users or $20M/mo revenue)

Qwen’s biggest models have never been open weight recently. Something is changing. You can imagine it like… Xi: no you’re not allowed to keep your best model closed anymore, we weren’t succeeding enough. A new era of competition for intelligence (if the benchmarks hold up).

Inkling was somewhat inevitable once Tinker took off -- integration of post-training services across @thinkymachines's entire stack -- and it's one of the best open-model business stories to date. Excited to see it grow and more emerge (some inference companies are next).

Thinky with a ~1T param, 41B active, apache-2 model Benchmarks are a clear step up from Nemotron Ultra (55B active), new best American model, and omni input. A bit behind GLM 5.2 on agentic benchies, and Kimi K 2.6 on multi modal Super exciting! Thank you @johnschulman2 & team
