X owner Elon Musk announced a major update to X’s AI recommendation algorithm that will roll out next week and be open sourced at the same time.

X launches Grok-powered AI custom feeds
X has launched Grok-powered Custom Timelines, a feature that lets users pin and browse more than 75 topic-specific feeds from the Home tab to complement Following and For You. The timelines are populated using xAI’s Grok, which reads posts to assign topic labels rather than relying on keywords or hashtags. X presented the feature (Nikita Bier, Head of Product) and initially offers it to Premium subscribers on iOS with Android support planned. Early hands-on reporting found the second slot in some custom feeds taken by an ad, indicating the change could create incremental ad inventory. The launch echoes functionality available on competitors (Threads, Bluesky/Attie) and raises both engagement and content‑bubble risks as highly personalized timelines drive deeper user dives into favorite topics.
Anthropic invests $100 million to train AI engineers
Anthropic has launched the Claude Frontier Academy with a $100 million investment to train 10,000 'frontier deployed engineers' (FDEs) by the end of 2027. The program, which includes a multi-day in-person session and a 12-week residency where engineers work on real Claude use cases, aims to bridge the enterprise AI talent gap. The first cohorts include engineers from Accenture, Bain, Capgemini, Commonwealth Bank of Australia, Deloitte, McKinsey, Morgan Stanley, and Novo Nordisk. Successful participants will earn the Claude Frontier Deployed Engineer badge, with first certifications expected in early 2027. This initiative builds on the Claude Partner Network, which has already certified over 175,000 professionals, and comes amid reports of Anthropic's potential IPO seeking a $2 trillion valuation despite significant operating losses.
