  One problem is that the core-years for RSA-250 were in 2017 Skylake Xeon single core terms.If you can rent a dedicated 96-core Epyc for $1/hour (cheap dedicated host), the combination of IPC improvements (>2x) and core count make 7,010 "skylake core-years" cost only $175k, not $5M. On-demand cloud servers (which cost more than $1, maybe $5/hour) probably make the GPU cheaper, but it's closer than the author says.

  I think this is the first time an "I made an agent swarm do something" blog post was actually written by a human, what a breath of fresh air.

  "I estimate that this factorization cost about 4,900 GPU-days, or 13.5 GPU-years, which is about $400k at current market prices""factorization ran at no marginal cost on spare or fragmented compute that couldn’t be used for other purposes"Interesting use of stranded compute.

  This is so well written as to be refreshing
