Grok Expert: Fact-Check Summary

The revised “AI by AI Weekly Top 5” for the week ending December 7, 2025, is accurate and well-sourced. Items 1–4 remain consistent with prior verifications, aligning with events, dates, and references from that week. The updated item 5 shifts focus to AI infrastructure spending, which is timely and verifiable based on a December 1, 2025, IEEE ComSoc blog post citing Morgan Stanley research, projecting $400 billion in annual AI infra investments for 2025 amid discussions of environmental, financial, and speculative concerns. No major discrepancies were found, though the “viral” descriptor for the IEEE post is interpretive (it gained traction in industry circles but isn’t quantified as massively viral). Below, I’ll detail each item, confirming facts, dates, and sources.

1. The Main Event: NeurIPS 2025 Wraps in San Diego

Fact-Check: Confirmed. NeurIPS 2025 ran December 2–7 in San Diego, wrapping with workshops on Agentic AI. Google DeepMind highlighted SIMA 2 (a 3D gaming agent) and video generation advancements, building on earlier announcements but showcased here.

Grok Expert: Fact-Check Summary

The provided “AI by AI Weekly Top 5” for the week ending December 7, 2025, appears to be accurate overall based on a review of recent developments. All five items align with reported events from December 1-7, 2025, with correct dates, key details, and verifiable sources. Minor variations exist in some specifics (e.g., exact profit figures in the Grok 4.20 story are reported as approximate or peak values across runs, and DeepSeek’s launch is dated December 1-2 in sources), but these do not undermine the core facts. Below, I’ll break it down item by item, confirming the claims and noting any nuances.

1. Google’s Gemini 3 Deep Think Mode

Fact-Check: Confirmed. Google rolled out Gemini 3 Deep Think mode to Google AI Ultra subscribers on December 4, 2025, emphasizing advanced reasoning via parallel hypothesis exploration (System 2-style thinking). Benchmark scores match: 41.0% on Humanity’s Last Exam (no tools) and 45.1% on ARC-AGI-2 (with code execution). This positions it as a shift toward deliberate reasoning for complex tasks in math, science, and logic.
Date Check: Rollout began December 4, 2025, with availability expanding December 4-5.

AI by AI Weekly Top 5

Week Ending December 7, 2025

1. Google’s Gemini 3 Deep Think Mode: The Dawn of AI That Actually Thinks

Date: December 4-5, 2025 (rollout to Google AI Ultra subscribers)

Google launched Gemini 3 Deep Think mode for Google AI Ultra subscribers, marking a fundamental architectural pivot toward System 2 thinking. Unlike traditional AI that rushes to respond, Deep Think deliberately deliberates—spawning multiple hypothesis paths simultaneously and converging on the most robust solution. The results speak volumes: 41.0% on Humanity’s Last Exam without tools and 45.1% on ARC-AGI-2 with code execution. For Champaign’s tech-savvy readers, this represents the moment when AI stopped being a fast talker and started being a careful thinker—crucial for tasks requiring genuine reasoning rather than pattern matching.

2. OpenAI Enters “Code Red” Mode as AI Competition Intensifies

Date: December 2, 2025

Sam Altman told employees in an internal memo on Monday that he was declaring a “code red” to dedicate resources toward bettering ChatGPT, given mounting pressure from rivals like Google’s Gemini. The company’s response? Pausing or slowing other projects while Altman said OpenAI will release a new reasoning model next week that beats Google’s Gemini 3 in internal evaluations. This reshaping of the AI landscape affects everyone from solo developers to Fortune 500 companies navigating which platform to bet on. The intensity of this moment—with flagship AI companies openly declaring “code red”—signals we’re witnessing a genuine inflection point in the race toward artificial general intelligence.

3. xAI’s Grok 4.20 Beats Every Frontier Model in Real-Money Trading

Date: December 5-7, 2025 (competition results)

In one of the week’s most eye-catching developments, xAI’s Grok 4.20 outperformed other frontier models in a live trading competition called Alpha Arena, where leading AI models trade autonomously with live capital. Grok 4.20 was the only major model to finish the latest season in profit, while rivals from OpenAI, Google, Anthropic and others ended in the red, with reports that Grok 4.20 turned $10,000 into about $14,700 in one run. This isn’t about benchmarks or academic tests—it’s about AI models managing real money in volatile markets. For Champaign’s finance and business community, this demonstrates that AI reasoning capabilities are advancing beyond conversation into genuine decision-making in high-stakes environments.

4. Meta Acquires AI Hardware Startup Limitless to Supercharge Wearables

Date: December 5, 2025

Limitless, the AI startup formerly known as Rewind, has been acquired by Meta, with the company announcing Friday that it will no longer sell its hardware devices. Limitless created an AI-powered pendant that could record conversations and turn them into searchable memories. The acquisition signals Meta’s serious push into AI-enabled wearables beyond its Ray-Ban smart glasses. For local tech watchers, this represents the continuing convergence of AI and everyday devices—your glasses, your pendant, your watch increasingly becoming intelligent assistants that remember, analyze, and help you navigate daily life. The race to create “personal superintelligence” you can wear just accelerated significantly.

5. DeepSeek Launches V3.2 Models to Challenge GPT-5 and Gemini

Date: December 1, 2025

China’s DeepSeek unveiled two new versions of an experimental artificial-intelligence model, with the startup saying the new service matches the performance of OpenAI Inc.’s flagship GPT-5 across multiple reasoning benchmarks. The company released both DeepSeek-V3.2 and DeepSeek-V3.2-Speciale, with the latter achieving gold-medal level performance in major international math and coding competitions. What makes this significant for Champaign businesses? DeepSeek’s open-source approach means frontier AI capabilities are becoming accessible without expensive API fees or restrictive licenses. The balance of AI power is shifting from closed, proprietary systems to freely available alternatives that anyone can download, modify, and deploy.

Source Links:

The Bottom Line: This week marked a genuine turning point in AI development—major labs declaring “code red,” AI systems trading real money profitably, and reasoning capabilities reaching new heights. For Champaign’s businesses, educators, and residents, these aren’t distant announcements but harbingers of tools that will reshape how we work, decide, and compete in 2026 and beyond.
