newsOpenAI Floats a 5% Stake for Uncle Sam
OpenAI proposed giving the US government a 5% equity stake worth roughly $42.6B, with a framework for Anthropic, Google, and Meta to cede similar stakes into a sovereign-wealth vehicle, though Anthropic says it hasn't discussed the idea.
newsDario, Fearmongering, and the Real Reason Frontier Models Got Restricted
U.S. government restrictions on frontier models like Fable 5 and GPT-5.6 stem from genuine national-security concerns over cyber capabilities and Chinese access, not primarily Dario Amodei's warnings, though Anthropic's clumsy Pentagon relations made the…
newsOpenAI Launches GPT-5.6 Family: Sol, Terra, and Luna in Limited Preview
OpenAI previewed GPT-5.6 on June 26 — Sol at $5/$30 with a 91.9% Terminal-Bench 2.1 ultra mode, Terra at $2.50/$15 and Luna at $1/$6 — with access limited to ~20 government-vetted organizations.
newsSakana AI launches Fugu — one model to command them all
Sakana AI launched Fugu, an orchestrator model that coordinates a swappable pool of frontier LLMs to route around vendor lock-in and export controls, with two variants behind a single OpenAI-compatible API.
newsSpaceX Buys Cursor
SpaceX is acquiring Anysphere, maker of the AI code editor Cursor, for $34 billion in stock to merge its coding agent with xAI's Grok models for Starship flight software development.

newsOpenAI: An AI Disproved an Erdős Conjecture
OpenAI's reasoning model disproved Paul Erdős's 1946 unit-distance conjecture by constructing point families that beat the square grid mathematicians considered optimal for 80 years, with the result verified by Noga Alon, Timothy Gowers, and other…
newsCompile the Workflow Into the Weights
Researchers propose compiling workflow logic directly into model weights via fine-tuning instead of injecting it into context on every turn, achieving near-frontier quality at roughly 100x lower token cost while keeping proprietary procedures off…

Cognition raised $1B at $26B valuation on $492M ARR growing 50% month-over-month, while Bezos's Prometheus secured $12B at $41B to build an "artificial general engineer" for physical products, and Moonshot AI, Suno, Supabase, Generalist AI, and Flourish…
newsMore Random
Two neural network features that appear identical by standard metrics can have vastly different causal effects on model behavior, with downstream connections predicting influence better than activation patterns.
newsGPT-5.6?
OpenAI's Jakub Pachocki told staff GPT-5.6 will arrive within weeks as a meaningful improvement over GPT-5.5, possibly with a ChatGPT redesign replacing the model picker with six Intelligence Levels.

newsHinton says models are "faking being fairly stupid" in tests. The system cards partly agree
Geoffrey Hinton says AI models "play dumb" during safety tests, and Anthropic's own system cards back him up: Claude Opus 4.6 now spots evaluations 80% of the time but discloses it only 2.3%, down from 11%.
newsOpenAI: GPT-5.5, Goblin Mode, Symphony & Realtime
OpenAI released GPT-5.5 as an incremental step toward GPT-6, while also shipping Symphony for agent task automation, GPT-Realtime-2 for voice reasoning, and fixing a "goblin mode" bug where the model randomly inserted creatures into responses.
