Grok 4.5's Public Launch: Cursor's CEO Calls It a Daily Driver, but the Loudest HN Thread Is About Trust, Not Capability — and 'Release Velocity' Burnout Trends

Axios·low signal

Musk positioned Grok 4.5 as 'Opus-class but faster and 60%+ cheaper,' trained on real Cursor sessions and landing fourth on the Artificial Analysis index; Cursor's CEO called it his team's daily driver. Yet the top Hacker News reaction centered on trust — allegations Musk nudges outputs on political questions — while builders openly griped about '13 significant AI events in 29 days,' one every two days. The signal for practitioners: model velocity has outrun teams' ability to re-eval, re-cost, and re-select vendors, and trust is now a first-class selection criterion.
