AI by AI Weekly Top 5 (Week Ending November 2, 2025)

Based on my search and verification, here are my recommendations for the most significant AI developments from this past week:

1. NVIDIA & Oracle Building DOE’s Largest AI Supercomputer (Oct 28)

NVIDIA and Oracle announced a landmark collaboration to build the U.S. Department of Energy’s largest AI supercomputer, with the Solstice system featuring a record-breaking 100,000 NVIDIA Blackwell GPUs and an Equinox system with 10,000 Blackwell GPUs. Located at Argonne National Laboratory, these systems will deliver a combined 2,200 exaflops of AI performance to accelerate scientific discovery across healthcare research, materials science, and energy applications. This represents a massive investment in AI infrastructure for public science research and demonstrates the government’s commitment to maintaining AI leadership.

2. OpenAI Launches ChatGPT Atlas Browser (Oct 21, with technical details Oct 30)

OpenAI launched ChatGPT Atlas, a new web browser with ChatGPT built-in, featuring a novel architecture called OWL (OpenAI’s Web Layer) that runs Chromium’s browser process outside the main app for faster startup and better isolation. Atlas includes agent mode that can complete tasks autonomously, browser memories that remember context from visited sites, and an “Ask ChatGPT” sidebar that works with page content. However, security researchers quickly flagged concerns about prompt injection attacks, where malicious websites could trick the AI into booking hotels, deleting files, or sending messages, with OpenAI’s CISO acknowledging prompt injection remains largely an “unsolved security problem”. This marks OpenAI’s direct challenge to Google Chrome’s dominance.

3. New AGI Definition Framework Scores GPT-5 at 57% (Oct 22)

A coalition of AI researchers including Dan Hendrycks, Yoshua Bengio, Gary Marcus, and Max Tegmark published “A Definition of AGI” proposing a measurable AGI scoring system based on Cattell-Horn-Carroll cognitive theory, with ten equal domains covering knowledge, reasoning, memory, and speed. Early results place GPT-4 at 27% and GPT-5 at 57%, revealing that GPT-5 scores zero on long-term memory storage since current models are “frozen” after training and cannot meaningfully learn from new experiences in deployment. This provides the first standardized benchmark for tracking progress toward AGI.

4. OpenAI Introduces GDPval Benchmark for Real-World AI Tasks (Oct 28)

OpenAI introduced GDPval, a new evaluation framework to track how AI models perform on economically significant, real-world tasks, shifting from academic benchmarks to actual workplace deliverables like drafting legal briefs, creating engineering diagrams, and developing nursing care plans. The benchmark spans 44 occupations from nine major industries contributing most to U.S. GDP and includes 1,320 specialized tasks, with a public “gold subset” of 220 tasks crafted and vetted by professional subject-matter experts. This represents a fundamental shift in how AI capabilities are measured.

5. OpenAI Reports Disrupting 40+ Malicious AI Networks (Oct 27)

OpenAI published its quarterly threat report revealing it has disrupted and reported over 40 networks that violated its usage policies since beginning public threat reporting in February 2024, including preventing AI use by authoritarian regimes to control populations and covert influence operations. The report notes that threat actors are bolting AI onto old playbooks to move faster, but are not gaining novel offensive capability from OpenAI’s models. This provides important transparency on AI misuse patterns and demonstrates proactive safety measures.

Honorable Mentions:

  • Britain’s Channel 4 launched “Arti,” an AI-generated news presenter using generative video and voice synthesis, marking a first in UK television history (Oct 27)
  • Microsoft rolled out Copilot Labs’ “Portraits” feature with 40 stylized human avatars using VASA-1 technology to animate speaking faces for more natural voice interactions
