Clearview AI Is Testing an AI Tool That Would Let Cops Unearth Your Life Online
Clearview AI is prototyping InquiryIQ, an AI analyst assistant that would automatically profile individuals identified through its face-recognition searches for police.
WIRED uncovered InquiryIQ, an unreleased Clearview AI prototype described as an AI analyst assistant that fans out across the web from a face-recognition search result to assemble profiles including employers, aliases, associates, and physical characteristics. The company tested a model from xAI (merged with SpaceX), maker of Grok, and the interface accepts age, gender, and race inputs to guide searches. Clearview says the prototype was never pitched or shipped to customers and no law enforcement user has used it; the database has grown to over 70 billion images used by more than 2,000 law enforcement agencies.
Cocomelon's Studio Tells Its Artists to Start Experimenting With AI
Moonbug Entertainment, studio behind Cocomelon and Blippi, issued generative AI guidelines requiring human authorship and legal review of all AI use.
Moonbug Entertainment, producer of Cocomelon, Little Baby Bum, Blippi, and Mia's Magic Playground, shared its 'Studio AI Bible' and generative AI policy with 404 Media. The guidelines permit AI for ideation, storyboarding, and utility tasks but require substantial human creative input on core elements, legal approval of every tool, and a 'provenance and isolation' filing system to preserve copyright. A spokesperson said generative AI is not currently used in aired episodes. Moonbug content has hundreds of millions of YouTube subscribers, with Cocomelon spinoffs on Netflix, a Universal movie in development, and a Disney+ move planned next year.
Meta says it’s changing AI suggestions after posing invasive personal questions
Meta is fixing Meta AI suggested prompts after a viral video showed the chatbot compiling invasive questions about a user's children from her Facebook posts.
Meta said it 'missed the mark' and has fixed the issue after Instagram user Kalie Robins showed Meta AI suggesting 'Who is the child passenger?' beneath a video with her child and then piecing together details about her daughters from her and relatives' posts. The assistant also surfaced photos of her children, including one the user claims she deleted years ago. Meta AI is embedded in Facebook, Instagram, WhatsApp, and Messenger; in July the company pulled an Instagram user-deepfake feature after backlash.
Meta debuts its Muse AI agent. Will consumers trust it?
Meta launched Muse, a consumer AI agent powered by Muse Spark that connects to users' apps to execute tasks like emailing, booking travel, and payments.
Meta introduced Muse, a personal AI agent for US users that connects to email, calendars, payments, shopping, and other services to execute tasks such as booking travel, lowering bills, and completing purchases via Link by Stripe. The agent runs in a dedicated Muse Secure VM with a separate Sentinel agent kept apart at the system level, and Meta claims it cannot see passwords or payment data and does not share conversations with ad systems. Muse is free to start, with Power ($20/month) and Maximum ($100/month) subscription tiers, and is available on the web, iOS, Android, and WhatsApp, with Meta AI glasses support planned. The launch follows Meta's $18 billion multistate consumer-harms settlement and comes as rivals like Gemini Spark and Claude Cowork push agentic AI.

ChatGPT advanced account security adds passkeys and hardware keys
OpenAI launches Advanced Account Security for ChatGPT and Codex, replacing passwords with passkeys or hardware keys and disabling email/SMS recovery.
The opt-in setting disables password sign-in plus email and SMS account recovery for ChatGPT and Codex accounts, allowing only passkeys, hardware security keys, and user-held recovery keys, with shortened sessions and automatic exclusion of enrolled accounts' conversations from model training. OpenAI partnered with Yubico to offer discounted bundles of the YubiKey C Nano and C NFC, while any FIDO2/WebAuthn-compliant key or software passkey is supported, mirroring standards adopted by Google, Microsoft, and GitHub. Individual members of Trusted Access for Cyber using the most permissive models must enable the setting from June 1, 2026, or their organizations can attest to phishing-resistant authentication in their single sign-on.
Coding Is Over. Get over It
A JPMorgan Chase engineer reflects on AI agents outpacing hand-coding, questioning ROI while predicting inference costs will become negligible.
A personal essay by a software engineer with 15+ years at JPMorgan Chase describes how AI coding agents now outperform him and have transformed his workflow. He argues AI ROI is unmeasurable, praises cheap small models such as GPT 5.6 Luna, and cites Claude Code head Boris Cherny's advice to discard AGENTS.md/Claude.md rule files. He contends coding is no longer scarce, worries entry-level jobs will be automated first, and predicts AI's bigger impact lies outside coding.
When companies get specific about AI, revenue growth looks different
A Carnegie Mellon and Larridin study of 564 companies links specific AI disclosures to 8 points higher revenue growth, not margins.
Researchers at Carnegie Mellon University and Larridin analyzed 564 companies across 12 sectors using 478 10-K filings, more than 30,000 classified job postings and an AI maturity tracker. Companies at the top of 'narrative concreteness', meaning they named deployed AI systems with measurable outcomes, were associated with 8.0 percentage points higher year-over-year revenue growth, while no public AI signal predicted operating margins or risk-adjusted stock returns. AI infrastructure suppliers outperformed matched peers by about 32 percentage points over four months. The authors stress the findings show association, not causation.
Opaque recurrence, and other AI terms that you should probably know
TechCrunch updates its plain-English glossary defining common AI terms from AGI and agents to chain-of-thought reasoning.
TechCrunch maintains a regularly updated glossary of AI terminology, defining terms such as AGI, AI agents, API endpoints, chain of thought, coding agents, compute, deep learning, and diffusion. It highlights 'opaque recurrence', the reasoning technique in OpenAI's new Astra model that has drawn attention from AI safety researchers. The piece is an educational living document rather than new research or a product announcement.
Architecting memory and storage in the AI era
Analysis argues AI inference shifts data-center bottlenecks to memory and storage, urging balanced compute, memory, storage, and network architecture over raw compute.
MIT Technology Review, citing Tirias Research principal analyst Jim McGregor, argues that AI inference and agentic workloads make data movement the key constraint, elevating memory and storage from background hardware to strategic assets. The piece says RAG and real-time inference require continuous data retrieval and caching that legacy infrastructure cannot support. It frames infrastructure planning as a business decision balancing performance, efficiency, cost, and scalability in healthcare, finance, and customer-facing AI.
