Ben Tossell@bentossellAI score10AIBen Tossell lists seven AI meeting tools, including dot, Grok bot, Poke, Instinct, OpenAI's meetings plugin, Granola, and Dia, that alert users to meetings, join Zoom calls, or take notes. He says the list means he should no longer miss meetings, but he says he was late because of the post itself.
Andrew Curran@AndrewCurran_AI score62AIOpenAI's research leaders say they parted ways with Jasmine, Mikita, and Tomek after an investigation found they violated policies on handling sensitive information. The company says the decision was not about raising safety concerns and that it is finalizing contracts with third-party safety assessors, with details to follow in the coming weeks.
Hamel Husain@HamelHusainAI score22AIHamel Husain advises reviewing real user interactions and showing the team the problems found. He says to then fix those problems and show what improved as the case for investing in evaluations.
Rohan Paul@rohanpaul_aiAI score46AISabi has raised a $50M seed round led by Vinod Khosla and Accel to build a baseball cap that turns brain signals into AI prompts. The cap can hold up to 100,000 sensors of 1 to 5 millimeters each, feeding a brain foundation model trained on 100,000 hours of labeled neural recordings. Sabi says the cap can predict a user's next 3-4 keystrokes from brain signals before they type them.
🚨 AI News | TestingCatalog@testingcatalogAI score62AISabi has raised $50M from Khosla Ventures, Accel, Initialized, DST, and Collab Fund, with Kevin Weil also participating. The company is building the Sabi Cap, a non-invasive wearable that aims to read brain signals and turn thoughts into text. Sabi says it designs its own custom chips and neuroimaging sensors, including a non-contact EEG chip fabricated by TSMC.
Santiago@svpinoAI score43AISabi has raised $50 million from Khosla Ventures, Accel, Initialized, Kevin Weil, and DST Global to build a wearable brain-computer interface. The company says its TSMC-fabricated chip reads brain signals without touching the scalp, with custom sensors collecting data and its own AI model decoding it into text. The device is a cap rather than an implant.
PixVerse@PixVerseAI score18AIPixVerse says it is collaborating with OpenAI on Prompt to Production, a learning initiative on AI-powered creative workflows. The initiative starts with two live sessions showing how to take a creative brief to a finished video using ChatGPT and the PixVerse Plugin.
PixVerse@PixVerseAI score14AIPixVerse says each session includes a platform walkthrough, a live OpenAI demo showing ChatGPT generating a creative brief and finished video via the PixVerse Plugin, a creator sharing their workflow, and live Q&A. The post presents these as recurring sessions rather than a new product launch.
PixVerse@PixVerseAI score17AIPixVerse says every attendee receives free credits to try its workflow. Those who complete the post-session survey may be randomly selected, with 100 winners per session, to win a month of ChatGPT Pro.
OpenAI Developers@OpenAIDevsAI score46AIOpenAI says Codex on Windows now has a new sandbox mode built on Microsoft's Execution Containers (MXC), offering faster setup, stronger network enforcement, and granular file access controls. The mode requires a compatible Windows 11 device. Background from Microsoft's announcement says MXC is now generally available on Windows 11, keeping agents within boundaries the operating system enforces.

AIA New York Federal Reserve Bank study found that US small businesses using AI are more optimistic about hiring and revenue than non-adopters. AI adopters expected a 33-point net increase in employment over the next year, versus 15 points for non-adopters. Only 31% of businesses have actually reported higher sales from AI so far.
AIJefferies Financial Group says the most likely long-term outcome of the AI boom is massive capital destruction in the US. It expects market share to go to cheaper open-source Chinese models.
AIJoachim Klement, managing director and research analyst at Panmure Liberum, says he sees risks in AI-related stocks and the potential for a severe AI-triggered market crash. He made the remarks on Bloomberg Open Interest.
AIThe original article discusses AI agents such as Muse that can shop on a user's behalf and what that could mean for retail stocks. The supplied text contains only site navigation and footer material, so no specific product details, figures, or market impacts can be confirmed.
AIBaseten explains how to decide which layers of a model can run in 4-bit NVFP4 without losing needed information. The post compares architecture-based heuristics, isolated-layer sensitivity scoring, and SaturationQuant, which accounts for other quantized layers. It also covers calibration with representative data and block-level scales of 16 values.
Why it matters: The post explains how to choose which layers run at NVFP4 precision using heuristics, sensitivity scoring, and saturation-aware scoring, with clear calibration steps.
AIInstinct, a startup AI agent that reached a $10 billion valuation in late September, handled everyday online tasks such as swim lesson searches and an Ikea return during a recent test, according to The Verge. The text-message-based agent works through iMessage, WhatsApp, or email, with no app or monthly subscription for now, and it connects to services like Google Workspace, Slack, and Notion. The reviewer found it matched rival agents Muse and Dots in many tasks, though it missed a prerequisite class detail on one website.
AIPresident Donald Trump has ordered federal use of "AI" replaced with "super intelligence," renaming the Center for AI Standards and Innovation to the Center for Advancing Innovation and Standards for Super Intelligence (CAISSI). Musk, Bezos, Jensen Huang and Sam Altman have praised the term, though Altman said OpenAI won't change its name. The article argues the rebrand is a euphemism that cannot dispel public concerns, such as those over data centers, and that Congress would still need to adopt it.
