The wider AI context around Claude — how the field is moving, what the terms mean, and which shifts actually change how you work.
Claude does not exist in isolation, and some questions only make sense one level up: what a context window really costs, why model tiers exist at all, how the agentic turn changed what these tools are for. This category holds the pieces that are about AI broadly rather than any single product, written for people who use these tools daily rather than for a general audience.
We keep it deliberately small. There is no shortage of AI commentary and very little of it helps you finish a task, so a piece only lands here when understanding it changes a decision you would otherwise get wrong — which model to reach for, what to stop paying for, which capability is real versus announced.
