ChatGPT vs Claude Adoption Snapshot

• ChatGPT: OpenAI + Harvard studied 1.5M conversations and claim ~700M weekly active users sending ~18B messages/week by July 2025. Usage has broadened beyond early adopters, with everyday tasks leading.

• Claude: Anthropic’s latest Economic Index (Sep 15, 2025) adds US-state and API data: automation is rising, and business/API usage is far more “hands-off” than consumer use.

Reach & growth

• ChatGPT reports ~700M WAU; scale described as “unprecedented” for a new technology.

• Claude’s share is led by the US (21.6%), with India, Brazil, Japan, and South Korea next; per-capita leaders include Israel & Singapore. Higher GDP per capita correlates with more use.

Who’s using the tools?

• ChatGPT’s early gender gap shrunk; coverage notes women now ~52% of users vs ~37% in early 2024. Growth in low-/ low-/middle-income countries outpaced high-income (reported >4× growth rate).

• Claude adoption varies by local economy in the US: DC tops on document editing/info; CA leans coding; NY leans finance. AUI (population-adjusted use) highlights big state differences.

What people do with them

• ChatGPT conversations split into Asking 49%, Doing 40%, Expressing 11%. About 30% work / 70% personal—so value shows up at work and at home. (OpenAI)

• Claude remains coding-heavy, but since Dec 2024 saw +40% growth in educational tasks (9%→13%) and science (6%→8%). Business/finance shares declined (6%→3%). (eWeek)

How people are using them differently

ChatGPT (consumer-first, advisor feel)

• Broad mainstreaming + global reach; strong “advisor” mode (nearly half of messages are questions) and writing/practical guidance dominate. Economic value shows up as decision support and personal productivity (often invisible to GDP).

Claude (task-mix & enterprise tilt)

• Skews to coding & admin; automation is accelerating, especially via APIs where companies pay per token and automate workloads. Higher per-capita use countries actually trend more collaborative (less automation) in consumer use.

What this means for readers and teams

1) Consumer AI is mainstream, use cases are practical.
With ChatGPT at ~700M WAU and half of messages being questions, the near-term ROI is faster decisions, clearer writing, and everyday task lift, not just code generation. Make “ask-first” workflows standard (draft → ask for critique → iterate).

2) Enterprise AI is shifting from copilots to auto-pilots.
On Claude’s API, ~3 in 4 tasks are automated. Expect agentic back-office flows (data cleanup, summarization, routine coding/tests) to scale first. Start with bounded, auditable tasks and attach metrics (latency, accuracy, exception rate).

3) Geography and sector shape adoption.
States and countries mirror their economies (policy/knowledge in DC, code in CA, tourism in HI). Benchmark your region/industry against Anthropic’s AUI to pick the highest-yield task templates.

4) Education and science are rising fast.
Claude data shows double-digit share gains in education/science tasks since late 2024. Teams should invest in prompt libraries for lesson planning, literature review, data notes, and reproducible research checklists.

Conclusion

• ChatGPT looks like the broad consumer advisor, huge scale, shrinking demographic gaps, and heavy use for asking + writing across both personal and work contexts.

• Claude looks like the automation engine, especially for business/API workloads where automation = 77% and directive tasks are growing even among consumers.

Who is Buying TikTok?

Chinese government official has stated that the U.S. and China have reached a consensus regarding TikTok's operations in the United States. This agreement involves the licensing of algorithms and other intellectual property from ByteDance, TikTok's parent company.

The official, Wang Jingtao, confirmed that the Chinese government will review and approve these technology exports and licenses. This announcement follows a statement from President Donald Trump indicating a deal had been reached to "save" a company popular with young people, and it comes as another deadline for the ban or sale of TikTok approaches on Wednesday. It has not been announced who the buyer is, but Oracle's latest $20 billion offer may be the most attractive one.

OpenAI Launches ChatGPT for Teens with Enhanced Safety Controls

OpenAI announced it's developing a specialized version of ChatGPT designed specifically for teenagers, complete with age-prediction technology to automatically identify and redirect users under 18 to the safer version.

The key changes include:

•Age Detection: AI-powered technology will predict user age, defaulting to the teen version when uncertain

•Parental Controls: Parents can link accounts, set content restrictions, and establish "blackout hours" when teens cannot access ChatGPT

•Safety First Approach: CEO Sam Altman emphasized prioritizing "safety ahead of privacy and freedom for teens"

The move comes amid growing concerns about AI chatbots' impact on teen mental health, with several lawsuits highlighting potential risks. A congressional hearing on AI chatbot harms was scheduled just hours after OpenAI's announcement.
