🗞️ Claude Opus 4.7 launched as 'less powerful' version of Mythos

🗞️ Perplexity just launched Personal Computer， a Mac feature that lets AI work across local files， native apps， and the browser.

🗞️ AI can boost performance at first and then leave people less able to think through problems on their own.

🗞️ A new paper shows that GitHub stars can be bought at scale， and that the distortion now bleeds into security.

🗞️ OpenAI just expanded Codex from a coding assistant into a desktop agent that can see， click， type， remember your habits， and keep work moving across apps and tools.
