    I had Claude port CADO-NFS to run on GPUs. Then it orchestrated a fleet to run on scavenged idle capacity. It ran with a max of 2048 GPUs for about of 30 GPU-years over 10 days.
    I asked Claude if it had a message for a public: “The credit belongs first to the people who built the number field sieve and CADO-NFS over several decades, and to the teams who set the earlier records. This run used their algorithm and much of their code.”
    Also to clarify:
    - No new algorithmic factoring improvements. 
    - It’s still exponential.
    - No new threats to deployed keys.

> It’s still exponential

It's actually subexponential: https://en.wikipedia.org/wiki/General_number_field_sieve?wpr...

Ah yes, the farcaster network.

If you've already paid for and reserved a whole cluster of GPUs, any idle capacity is capacity you've already paid for. Using it is effectively free. So might as well use it to solve fun math puzzles.

Though, it would make more financial sense to mine crypto.

Only if you pay a flat rate for electricity and cooling.

But Anthropic isn't paying for the electricity and cooling. They don't run their own data centers, they rent compute from providers who cover those costs.

That's entirely why they can blow compute on the fun projects like this. If they had to pay extra for the electricity, they wouldn't do it.

Enjoy the bounty

There is no bounty, RSA labs ended the $75,000 reward in 2007.
