#1Claude Design

Anthropic has launched Claude Design, a new product from Anthropic Labs that lets users collaborate with Claude to create polished visual work including designs, prototypes, slides, and one-pagers. Powered by Claude Opus 4.7, it's available in research preview for Pro, Max, Team, and Enterprise subscribers. The platform integrates with existing design systems and allows seamless handoffs to Claude Code for implementation.

#2Claude Opus 4.7 Costs 20–30% More Per Session

Independent testing reveals that Claude Opus 4.7's new tokenizer inflates real-world token usage by a 1.47x multiplier — significantly higher than Anthropic's documented 1.0–1.35x estimate. The practical cost increase means developers and startups building on the API are paying roughly 20–30% more per session than expected. This is a critical data point for anyone budgeting AI inference costs.

#3I'm Spending 3 Months Coding the Old Way

Developer Miguel Conner is doing a three-month coding retreat at the Recurse Center in Brooklyn, deliberately building projects without AI assistance. He argues that hand-coding builds deeper understanding and stronger mental models, comparing it to mental gym workouts. His goals include training an LLM from scratch and improving low-level programming skills.

#4Isaac Asimov: The Last Question (1956)

Asimov's classic short story spans ten trillion years, following humanity's relationship with increasingly powerful computers. Each generation asks the same question — can entropy be reversed? — and each computer replies "insufficient data for a meaningful answer" until the final cosmic AI discovers the solution by recreating existence itself.
