Researchers at Graphite analyzed writing habits of frontier language models to identify persistent linguistic “tells” that distinguish AI-generated prose from human writing. They defined 13,000 phrases as tells that were at least twice as common in AI content as in a 10,000-article human control set, finding that Claude Opus 5.5 uses “this matters” 116 times more often and “dependable” 23 times more often. Em-dash overuse is reduced or nearly eliminated, but other telltale constructions shift rather than disappearing, with each model version showing its own distinct quirks.
OpenAI introduced Dots, a personal AI agent showcased at DevDay 2026 as a direct challenge to Meta’s Muse platform. It said Dots is powered by GPT-6 Astra. The focus shifts to competing on agent capabilities like generating virtual worlds, while Meta’s early momentum is now met with a new paid-entry alternative (though the article doesn’t provide pricing details).
Deepslate raised €7.7 million to build a speech-to-speech AI model and is operating its system on servers in Germany. The model’s time to first audio was measured at 0.44 seconds by Artificial Analysis. Deepslate’s funding supports faster real-time voice responses while positioning the company to offer customers a locally deployable, sovereignty-focused model.
