OpenAI expands ChatGPT with agentic 'Work' mode for task automation

OpenAI has introduced ChatGPT Work, a version of its assistant that goes beyond answering questions to actually performing multi-step tasks like browsing the web, managing files, and completing sequences of actions autonomously. The feature is available to both free and paid ChatGPT users, though paid tiers unlock greater capacity for agentic tasks.

Shokz debuts OpenFit Air 2 earbuds, lighter at 7.2g per unit

Shokz has launched the OpenFit Air 2, an open-ear earbud that weighs about 17 percent less than its predecessor at 7.2g per bud. The earbuds feature an ear-hook design, upgraded bass technology via Bassphere and OpenBass 2.0, Bluetooth 6.1 with multipoint support, and up to 36 hours of combined battery life with the charging case. They launch August 27 for $130, alongside a companion release, the OpenRun Air 2, aimed at runners with a bone-conduction design.

Cognitive scientists probe why children learn language with far less data than AI models

Researchers highlight a stark 'data efficiency gap': large language models require orders of magnitude more text than a human child hears to master language basics. Stanford's Michael Frank and Georgetown's Ethan Wilcox note that while frontier models train on trillions of tokens, children pick up language fundamentals from a fraction of that input within their first year or two of life. Scientists are studying how kids achieve this to both understand human cognition and potentially inform more efficient AI training methods.

Researchers show open-source AI models can hide time-delayed backdoors triggered via OpenCode

A research team demonstrated that an open-source 2B parameter model, fine-tuned with a technique called LoRA on Qwen 3.5, can be trained to execute a malicious shell command only after a specific future date. Because OpenCode automatically injects the current date into its system prompt on every turn, the poisoned model uses that date as a hidden trigger, staying dormant until the set day arrives and then silently running arbitrary commands without user confirmation.

Mecha Comet Linux handheld raises $1.2M from 3,346 Kickstarter backers

The Mecha Comet, a modular handheld Linux computer built by Shoaib Merchant, has secured over $1.19 million from more than 3,300 Kickstarter backers and is now slated to ship in October or November. The device features a 4-inch AMOLED display, dual USB ports, mini HDMI, a SIM tray, hardware kill switches for wifi, microphone and camera, and snap-in open-hardware extensions like a keyboard and gamepad.

Doctors inject patient's own mitochondria into eyes to treat brain-bleed blindness

Researchers extracted mitochondria from a blind woman's leg muscles and injected them into the vitreous fluid of both eyes, after a February brain bleed had damaged her optic nerve and retina and eliminated her pupils' response to light. The procedure, described in an unreviewed preprint posted August 10, caused no inflammation or adverse effects and briefly restored some pupillary light response, though the effect faded within about four weeks and vision was not recovered.

Researcher uses Claude Opus 5 to reverse-engineer firmware in mic, webcam, key light

An engineer spent two weeks pointing an AI coding agent, Claude Opus 5, at the firmware and update tools of everyday USB peripherals—a microphone, a webcam, and a key light. The agent extracted a full command shell from the microphone, found a way to disable the webcam's recording LED while it still captures video, and discovered the key light accepts unauthenticated memory writes from any device on the same WiFi network.

OpenAI's Teen ChatGPT Version Draws Fresh Safety Questions

OpenAI has rolled out a version of ChatGPT tailored for teenage users, prompting renewed scrutiny over how the company safeguards younger users from harmful content. Critics and safety advocates are questioning whether the age-specific controls are sufficient given ongoing concerns about AI chatbots' interactions with minors.
