12 months of progress on the jagged frontier:
1) AI got spikier, not rounder.
2) Maths, fluid reasoning, expert work: past human level.
3) There is almost no middle ground. Once a capability crosses human level, it often quickly becomes 100x+ cheaper than a human.
4) Cost keeps decreasing after capability increases stop. Language and knowledge look saturated but price keeps falling.
5) The gaps are not a budget issue. Human-level memory, self-monitoring and long-run planning are not for sale at any price.
AI is now a superhuman specialist that is sub-human at running itself.
