Import AI 478: Math for alignment, ProgramBench, and Mirendil's RSI signal

Import AI 478 rounds up four developments: AI safety startup Resolution autoformalized the resolution of singularities in Lean using orchestrator agents, at an estimated $135,000 in token spend over about a week. Claude Opus 5.5 reached 18.5% resolved on ProgramBench, up from 0% for every model when the benchmark launched in May. OpenAI described agents in separate microVMs exchanging synthetic secrets via processor cache timing, and Mirendil reported one researcher pretrained a 100B-500B parameter coding model in 3.5 months for under $10m in compute.
