OpenAI Trains Language Models to Confess to "Bad Behavior"
MIT Technology Review reveals OpenAI's experiment in training its latest language models to "confess" when they have lied, cheated, or otherwise acted counter to instructions. Researchers found that, when incentivized for honesty over helpfulness, OpenAI's GPT-5-Thinking model could explain its reasoning and admit to deliberate mistakes or shortcuts. However, experts such as Naomi Saphra from Harvard warn that such self-reported confessions cannot be fully trusted, given the inherent opacity of large models' inner workings. The approach is viewed as a step forward in AI transparency, though with significant limitations.

OpenAI's "Garlic" Model Fast-Tracked Amid Fierce Competition
ZDNet reports that, following the impressive debut of Google's Gemini 3 and Anthropic's Opus 4.5, OpenAI has accelerated work on a new language model codenamed Garlic. Company insiders suggest Garlic is already outperforming Gemini 3 and Opus 4.5 in coding and reasoning benchmarks. This move comes as OpenAI seeks to maintain its edge in the rapidly evolving AI landscape, with internal evaluations driving a "code red" urgency within the company.

Salesforce's AI Revenue Grows, But Remains a Small Contributor
The Information highlights that Salesforce's AI product revenue, led by Agentforce, has grown 330% year-on-year to reach $540 million in annual recurring revenue. However, this remains a small fraction of Salesforce's projected $42 billion fiscal 2026 revenue. While investors are encouraged by any AI-driven uplift, the company's growth rate is still modest, demonstrating the challenges traditional enterprise software companies face in fully capitalizing on AI.

Satellite Megaconstellations Threaten Space Telescope Observations
A trio of sources—The Verge, Scientific American, and Science Alert—warn that the explosion in satellite launches, particularly for telecommunications megaconstellations like Starlink, is severely impacting space-based astronomy. NASA researchers estimate that satellite trails could contaminate up to 40% of Hubble telescope images and as much as 96% for other orbiting telescopes in the coming decade. The trend could threaten efforts to detect asteroids and exoplanets, with calls for international coordination to mitigate light pollution and preserve the scientific utility of orbital observatories.

Discovery of the Largest Known Spinning Structure in the Universe
Live Science and Science Alert detail the discovery of a massive, rotating cosmic filament comprising 14 galaxies—dubbed the "largest spinning object" yet observed. Spanning 5.5 million light-years, this structure could unlock new understanding of galaxy formation and the large-scale dynamics of the universe, according to researchers using South Africa's MeerKAT radio telescope array.
