Claude Opus 4.6 Solves Open Combinatorics Problem That Stumped Knuth for Weeks
Anthropic's Claude Opus 4.6 solved a Hamiltonian cycle problem Knuth worked on for weeks. Multiple AI systems then closed the remaining cases.
Funding
Track where AI money actually moves, not where the hype points. We decode funding rounds, acquisition patterns, and strategic bets that reveal what investors believe will win. From mega-rounds in foundation models to quiet exits in automation plays, the capital flows expose which technologies attract patient money versus quick flips. Watch who's doubling down on agents, who's backing infrastructure, and which VCs are silently repositioning. The checks don't lie.
