Trump Signs Voluntary 30-Day AI Executive Order — Musk and Zuck Pared It Down From 90

Signed June 2 — AI companies are asked (not required) to share covered frontier models with the federal government for up to 30 days before release.
Earlier May draft set a 90-day window; lobbying by Musk and Zuckerberg shortened it, and the final text explicitly bars any mandatory licensing or preclearance.
Directs NIST to author the voluntary framework and stands up an 'AI cybersecurity clearinghouse' to share vulnerability info across agencies.
HN front page (Trump signs downsized AI order after weeks of reversals): voluntary scheme + 'trusted partner' carveouts dominate the comment thread.

Headline of OpenAI's June 2 'Intelligence at Work' livestream: Codex is being repositioned from a coding agent to a generalist white-collar workhorse.
Six role plugins (sales, data analytics, creative, product design, public-equity investing, investment banking) bundle 62 business apps and 110 prebuilt skills.
'Sites' spins up OpenAI-hosted dashboards and internal web apps from a prompt; 'Annotations' lets users highlight a region of a doc, sheet, or slide and edit it in place.
OpenAI now claims 5M weekly Codex users, with non-developers ≈20% of the base and growing 3× faster than engineers; Codex rolls into the ChatGPT app 'in the next few weeks'.

June 2 expansion of the Mythos-powered security program from 50 pilot partners to 150 across power, water, healthcare, communications and hardware.
Named additions include Okta, Samsung, SK Hynix, SK Telecom, NATO and the EU's ENISA — each had to clear Anthropic's security bar to get model access.
Mythos has now flagged 23,000+ potential vulnerabilities (Anthropic projects ~6,000 confirmed severe), up from the 10,000 disclosed in the initial-update post.
HN thread front-pages within hours; top concern is the dual-use shape of a model that finds zero-days at this rate now sitting inside infrastructure operators.

Jensen's June 1 Computex keynote: Nvidia's first PC-class chip, co-designed with MediaTek; ships in Windows-on-Arm laptops from Microsoft, Dell, HP, Asus, Lenovo and MSI in fall 2026.
20-core Arm CPU plus 6,144 Blackwell CUDA cores (RTX 5070-class) and up to 128GB unified memory — Apple M-series-style addressing for AI workloads.
A cheaper N1 variant lands with 12-core CPU / 2,560 CUDA cores; both run CUDA natively, which is the real moat versus Snapdragon X and AMD's Strix Halo.
Frames Nvidia's stack-from-cloud-to-PC pitch: same CUDA story from Blackwell servers down to the laptop you train and infer on.

June 2 — GPT-5.5, GPT-5.4 and the Codex agent are now generally available through Amazon Bedrock in commercial and GovCloud regions.
Pricing matches OpenAI's first-party rates and Bedrock usage counts toward existing AWS commitments — no separate procurement contract.
Codex on Bedrock is reachable from the Codex App, Codex CLI and the VS Code / JetBrains / Xcode plugins, with all inference routed through AWS.
OpenAI cites 4M weekly Codex developers; signal-wise this closes the loop where Anthropic (already on Bedrock) had a structural advantage for AWS-native enterprises.

June 1 — Grok Build's /models menu now serves Composer 2.5, the Cursor coding model built on Moonshot's open-weight Kimi K2.5 checkpoint with heavy RL post-training.
Pricing: $0.50 / $2.50 per 1M input/output tokens; a faster variant at $3 / $15 per 1M — roughly 10× cheaper than Opus 4.7 or GPT-5.5 at similar SWE-Bench scores.
Comes with the disclosure that xAI's next Grok Build model is being trained from scratch on Colossus 2 with ~1M H100-equivalents in a SpaceXAI / Cursor compute partnership.
Reaction on r/cursor and HN reproduces the May launch debate: benchmarks competitive on the easy 80% of tasks, but devs still alt-tab to Opus 4.7 for the hard 20%.
