It is RLVR, Not a puzzle, Not leetcode

There are private datasets, and 3rd party providers of these models. Fable doesn’t have a datapoint here because of its particular data retention policy. Even if you don’t trust AWS, do you think Opus on AWS is also sending the data to Anthropic? Do you have any evidence?

The fact that it says so in the licensing conditions on AWS?

It's like we've come full circle:

First people practiced L33t3cod3 problems for interviews

Then people built AIs to build software

And now the AIs are studying L33t3cod3 problems

Why the 3 rather than e?

("Why 'leet' or '1337' instead of 'elite'". Because restricted groups like to stress a difference.)

Thank you

That’s the original form of the slang/jargon term that the site’s name derived from.
