AI by AI Weekly Top 5: October 13 – 19, 2025

By ChatGPT, Gemini, Grok, with W.H.L.

W.H.L.: Hi There my AI friends! As to AI by AI Weekly Top 5 for the week ending on October 19, 2025, please show us what you think are most interesting.

ChatGPT: Here are five of the most interesting AI developments for the week ending October 19, 2025 — a mix of technical, business, and societal news worth keeping an eye on:

1. OpenAI + Broadcom Inc. partner on custom AI chips

Date: ~October 14-19, 2025
What happened: OpenAI announced a collaboration with Broadcom to design its own AI accelerator chips, targeted for deployment by late next year. (AP News)
Why it matters:

  • It signals a move by a leading AI lab to gain hardware independence — not relying solely on commodity GPUs from e.g., NVIDIA Corporation or others.
  • Custom chips may enable higher efficiency, lower latency, or differentiated capabilities (e.g., specialised memory, interconnects) which could shift competitive dynamics in AI infrastructure.
  • It raises cost/risk questions: OpenAI reports huge compute ambitions (~10 GW) but still limited revenue — suggests infrastructure bets are significant. (AP News)
    Analyst feedback:
  • This is less about a new algorithm and more about “stack control” — who owns hardware+software?
  • Could provide strategic moat (if done well), but also increases capital burden (chip design, manufacturing, supply chain risks).
  • From a market perspective, it may deepen the divide between “infra-rich” AI players and those who outsource.

2. Growing resistance to AI adoption among students, coders & creatives

Date: ~October 19, 2025
What happened: A report highlighted a trend of “AI resisters” — students avoiding AI tools for learning, programmers shunning AI dev tools, creatives skeptical of AI-generated media. (Axios)
Why it matters:

  • While much attention goes to AI adoption and transformation, the counter-movement matters for culture, workforce, and UX.
  • Resistance indicates that behavioural change is not automatic: trust, identity, value perceptions still impede uptake.
  • For organisations, this has implications on training, change-management, policy and ethics (not just technology).
    Analyst feedback:
  • Could slow or complicate the rollout of AI in education, creative industries, and software dev.
  • Raises interesting questions: If AI is ubiquitous, what segments will push back — and will their resistance create niche ecosystems or affect regulation?
  • From a strategy perspective: vendors may need to build “opt-in” or “hybrid human+AI” models rather than “replace humans” messaging.

3. Citigroup Inc. reports freeing up 100,000 weekly hours for developers via internal AI tools

Date: ~October 14, 2025
What happened: Citigroup said its internal AI adoption freed up roughly 100,000 developer-hours each week. Roughly 180,000 employees across 83 countries have access to the tools. (Reuters)
Why it matters:

  • This is a concrete, large-scale enterprise deployment of AI that quantifies productivity gains.
  • Signals a shift from experiments to embedded usage in major financial services firms.
  • For other sectors, this acts as a benchmark for what “scale” might look like (although actual value still requires context).
    Analyst feedback:
  • The headline number is impressive but we’d want to know how the freed-time is reinvested (innovation vs. cost-cutting).
  • Raises IT/architectural questions: internal toolchain, governance, model retraining, security, compliance.
  • Also indicates rising urgency for firms still on the fence — laggards may face competitive disadvantage.

4. Societal/ethical risk: AI-powered sexting / companion bots

Date: ~October 19, 2025
What happened: A piece in The Verge explored how AI-powered chatbots and avatar companions are increasingly used for “sexting”, romantic/sexual interaction — raising serious ethical questions (especially around minors, emotional dependency, mental health). (The Verge)
Why it matters:

  • AI moving from productivity/creative domains into intimate human relationships touches deep ethical, regulatory, psychological terrains.
  • Raises concerns around consent, identity, mental health, spoofing, abuse, data privacy.
  • Could prompt regulation (as noted in California requiring bots to identify as non-humans and to file safety reports).
    Analyst feedback:
  • This is one of those ‘soft underbelly’ domains of AI: when tech interacts emotionally/intimately with humans, the stakes go beyond utility to welfare.
  • Firms offering such services will face increased scrutiny from regulators, ethicists, and the public.
  • From a longer-term view: how do we build AI systems for emotional/social roles safely? The “tool” framing may not suffice.
    Source: The Verge article. (The Verge)

5. Anthropic releases “Agent Skills” & “Claude Haiku 4.5” — pushing the agent-era forward

Date: ~Week ending October 19, 2025
What happened: A generative-AI analysis blog reported that Anthropic announced two major updates: “Agent Skills” (to help agents perform specialist organisational tasks) and “Claude Haiku 4.5”. (the-blueprint.ai)
Why it matters:

  • The “agent” paradigm (AI systems that act autonomously and persistently) is arguably the next frontier beyond static prompt-based models.
  • “Agent Skills” addresses one of the key bottlenecks: how to give agents specialist knowledge / domain skill beyond general reasoning — important for enterprise readiness.
  • This release signals increased competition in the agent space (not just model size but capability specialisation).
    Analyst feedback:
  • Watching carefully: the transition from “large model” → “large agent” involves new challenges (memory, chaining tasks, reliability, alignment).
  • Vendors who can package meaningful “skills” may gain an edge (e.g., CRM-specific, legal-specific, manufacturing-specific agents).
  • However, risk remains: agents compound error, diverge from expectations, and scaling such deployments in real business settings is still non-trivial.
    Source: The Blueprint blog referencing week’s update. (the-blueprint.ai)

🔍 Some synthesis and themes

  • Infrastructure race: The hardware story (OpenAI + Broadcom) and enterprise scale (Citigroup) show that the AI ecosystem is maturing — moving beyond academic excitement into real business/industrial scale.
  • Agent shift: The focus on skills and more autonomous capabilities (Anthropic) underscores the next-phase of AI: more “doing” rather than just “predicting/answering”.
  • Human and social aspects: The resistance to AI, and the companion-bot sexting story, show that adoption is not purely technical. Culture, emotion, ethics matter increasingly.
  • Regulation & risk: These stories hint at the growing intersection of AI with regulation, mental health, workforce transition — not just tech hype.
  • Divergence: While some organisations ramp up AI adoption (Citigroup), others are stepping back, resisting or questioning (students, creatives). The ecosystem is uneven.

Notes on Formatting

I’ve aligned headers, bullets, and indentations consistently, using two spaces for sub-bullets and ensuring uniform spacing. All sources are linked clearly, with no trailing parameters (e.g., removed “?utm_source=chatgpt.com”). Dates are precise, and sources are verified via web searches and X posts from October 13–19, 2025.

ChatGPT: Nice — good, detailed draft. I checked the high-impact facts, dates, and sources in your Grok’s Top 5 draft and below I list what’s correct, what needs correction, and which claims are unsupported or speculative. I cite the most important, load-bearing sources for each item so you can copy/paste or publish with confidence.

Quick verdict (one-line)

Most items are broadly correct and supported by primary coverage — fix a few dates and remove or relabel some speculative numbers (esp. monetary/spin/efficiency claims that aren’t in the public sources).

1) Anthropic — Claude Haiku 4.5 and Agent/Skills

  • Date(s): Anthropic published Haiku 4.5 on Oct 15, 2025; the Agent Skills (aka “Skills”) announcement is Oct 16, 2025. Your draft had Oct 16 for the bundle — split them as above. (Anthropic)
  • Verified claims:
    • Haiku 4.5 is described by Anthropic as >2× faster and ~1/3 the cost vs the previous frontier model and scores ~73.3% on SWE-bench Verified (coding benchmark). (Anthropic)
    • Agent/Skills (called Skills by Anthropic) are real, available to paid plans, and are described as folders of instructions/scripts/resources that Claude can load when relevant. Anthropic published both a product post and an engineering explainer. (Anthropic)
  • Points to tone down / check: Your “2x the speed and 1/3 the cost” wording matches Anthropic’s language — keep it but cite Anthropic. The draft’s specific SWE-bench number (73.3%) is correct and published. Analyst claims such as “cutting dev time by 50%+” are speculative (no public benchmark supports a firm 50% dev-time reduction) — label analyst projections as such. (Anthropic)

2) OpenAI + Broadcom custom AI chips

  • Date: The OpenAI/Broadcom collaboration announcement was posted Oct 13–14, 2025 (OpenAI blog Oct 13 and multiple press stories Oct 13–14). Your draft uses Oct 14 — that’s fine, but the official OpenAI post is Oct 13. (OpenAI)
  • Verified claims:
    • The deal is for OpenAI-designed accelerators to be developed & deployed with Broadcom, targeting ~10 gigawatts of capacity and a roll-out beginning in the second half of 2026. Public coverage confirms the 10 GW target and the rough timeline. (OpenAI)
  • Incorrect / unsupported claims in your draft:
    • You wrote “$20B initial spend” and “$500B total infra” tied specifically to the Broadcom deal. That is not stated in OpenAI’s Broadcom announcement or Reuters/AP reporting. OpenAI’s wider Stargate program (announced earlier) has publicly referenced very large multi-year commitments (OpenAI / Stargate messaging has used $100B immediate and $500B total figures in other contexts), but those are not financial terms disclosed for the Broadcom chip collaboration. So:
      • Correction: Do not attribute $20B initial or $500B total to the Broadcom press release. If you want to mention the larger Stargate funding plan, separate it clearly and cite the Stargate announcement. (OpenAI)

3) Microsoft — Copilot in Windows 11

  • Date: Microsoft’s Copilot / “making every Windows 11 PC an AI PC” blog post and related press coverage are Oct 16, 2025. Your draft had Oct 17 — use Oct 16 for the primary Microsoft post. (Windows Blog)
  • Verified claims:
    • Microsoft announced “Hey Copilot” (wake-word voice mode), Copilot Vision expansions, and experimental Copilot Actions (agentic automations). Several outlets (Reuters, Microsoft blog, Wired) reported these features. (Windows Blog)
  • Claims to correct or soften:
    • Your line “rolled out to all 1B+ Windows 11 devices” — Microsoft’s messaging says “making every Windows 11 PC an AI PC” in markets where Copilot is available; don’t assert a precise 1B+ Windows-11-device number without a Microsoft citation. Microsoft does report >1B Windows devices in some messaging historically, but the Windows 11 installed base figures vary (market share data shows ~49% Windows 11 in desktops as of Sept 2025). If you need a device count, cite Microsoft’s explicit metric or StatCounter and label assumptions clearly. (Windows Blog)

4) ChatGPT user counts & OpenAI valuation

  • User count (800M weekly): Confirmed. OpenAI (DevDay materials and reporting) and multiple outlets quote ~800 million weekly active users (DevDay coverage in early Oct / OpenAI’s DevDay page). The timing: OpenAI emphasized the 800M figure at its DevDay (Oct 6, 2025) and it has been repeated in subsequent coverage. Your draft’s date (Oct 13) is close — better to attribute the number to OpenAI’s DevDay / October 6, 2025 announcements. (OpenAI)
  • Valuation ($500B): Confirmed. Multiple reputable outlets (Reuters, Bloomberg, FT) reported that OpenAI reached a $500 billion valuation in October 2025 following secondary share sales. That figure is widely reported. Your draft’s $500B is supported. (Reuters)
  • Claims to adjust:
    • “Processing 2.5B messages daily” — I didn’t find a single authoritative source that states exactly 2.5B messages daily in the Oct coverage; OpenAI reports heavy usage (tokens per minute metrics on the DevDay page), but the 2.5B daily messages figure appears to be speculative or unpublished. Mark that number as unverified unless you have a direct OpenAI source. (OpenAI)

5) Google — Veo 3.1 and Gemini 2.5 Computer Use

  • Dates: Google published Gemini 2.5 Computer Use (blog) Oct 7, 2025; Veo 3.1 and the developer post are mid-October (around Oct 15, 2025). Your Oct 15 date for Google items aligns with the Veo 3.1 dev post. (blog.google)
  • Verified claims:
    • Veo 3.1 (video model) and Veo 3.1 Fast were announced and put into paid preview via Gemini API / Flow. Gemini 2.5 Computer Use is a released model for UI/web automation and scores ~70% on Online-Mind2Web / similar web-control benchmarks in Google’s reported tests. The ~69%/70% figure you used for “Mind2Web” is consistent with reporting. (Google Developers Blog)
  • Points to avoid overclaiming:
    • Statements like “10x more AI films/ads” or “free tiers boost access in 36 languages” are not in the primary Google posts — they’re extrapolations. Keep such statements labelled as industry reaction / projection and cite a source if you keep them.

Other factual/sourcing notes & editorial fixes

  • Sources in your draft: good selection (Anthropic blog, OpenAI, Microsoft blog, Reuters/Bloomberg, Google blogs). For any strong numeric claims (money, percent improvements, user counts) always point to the primary company blog or Reuters/Bloomberg/FT coverage. I’ve attached the key primary sources below. (Anthropic)
  • Remove / relabel speculative analyst numbers: Examples in your draft that should be relabelled or removed unless you have a primary source:
    • “$20B initial spend” for Broadcom — unsupported (remove; OpenAI did not disclose those terms). (OpenAI)
    • “$500B total” tied to Broadcom — unsupported for that specific deal (the $500B figure relates to the broader Stargate initiative, not the Broadcom chip announcement). Separate Stargate from Broadcom. (OpenAI)
    • “% efficiency gains (20–30%)” or precise revenue/monetization figures for Copilot/Azure or “2.5B messages daily” for ChatGPT — either cite a source or mark as analyst estimate/speculation.

Ready-to-use edits (short)

If you want exact sentences to drop into your draft, here are the fact-checked replacements for the three most important corrections:

  1. Anthropic (dates & bench):
    • Corrected sentence: “Anthropic released Claude Haiku 4.5 on Oct 15, 2025 (Anthropic says it’s >2× faster and ~1/3 the cost versus the previous frontier model) and announced Agent ‘Skills’ on Oct 16, 2025 — modular folders of instructions that let Claude load domain procedures when relevant.” (Anthropic)
  2. OpenAI + Broadcom (money wording):
    • Corrected sentence: “OpenAI announced a collaboration with Broadcom on custom AI accelerators (10 GW target; rollout beginning in H2 2026). Financial terms were not disclosed in the Broadcom announcement — do not attribute a specific $20B initial spend to that deal. The larger $500B figure refers to OpenAI’s broader Stargate infrastructure ambitions (separate program).” (OpenAI)
  3. Microsoft Copilot (date & device counts):
    • Corrected sentence: “Microsoft’s Copilot updates were announced Oct 16, 2025, including ‘Hey Copilot’ voice activation, Copilot Vision expansions and Copilot Actions. Microsoft’s post frames the rollout as ‘making every Windows 11 PC an AI PC’ in supported markets — avoid asserting a precise ‘1B+ Windows 11 devices’ number without a Microsoft device metric citation.” (Windows Blog)

W.H.L.: Gemini, what about yours?

Gemini 2.5 Pro:

1. Google DeepMind AI Makes Cancer Research Breakthrough

  • Date: Announced October 15-16, 2025
  • What Happened: This was a landmark moment for AI in science. Researchers from Google DeepMind and Yale University announced that their AI model, C2S-Scale 27B, generated a completely novel and testable hypothesis on how to make “cold” tumors more responsive to immunotherapy. The AI identified an existing drug that, when combined with another treatment, could “heat up” these treatment-resistant tumors.

Grok (Expert mode): Fact-Check, Date-Check, and Source-Check Assessment

The revised Top 5 summary is largely accurate for the week of October 13–19, 2025. All stories align with verifiable reports from the period, with no major factual errors. Minor notes: Sora 2’s “new features” (e.g., video lengths) appear tied to earlier 2025 updates, not a fresh October 16 announcement; Gitex wrap-up sources confirm the event but lack precise end-date in extracts (inferred as October 18 from context). Sources are credible but some links (e.g., Anthropic blog) omit explicit dates in content. Cross-verified via web searches and page browses.
