Claude Sonnet 4.5

That (thankfully) can't compound, so would never be more than a one time offset. E.g. if you report a score of 60% SWE-bench verified for new model A, dumb A down to score 50%, and report a 20% improvement over A with new model B then it's pretty obvious when your last two model blogposts say 60%.

The only way around this is to never report on the same benchmark versions twice, which they include too many to realistically do every release.

The benchmarks are not typically ongoing, we do not often see comparisons between week 1 and week 8. Sprinkle a bit of training on the benchmarks in and you can ensure higher scores for the next model. A perfect scam loop to keep the people happy until they wise up.

You don't need to compare "A (Week 1)" to "A (Week 8)" to be able to show "B (Week 1)" is genuinely x% better than "A (Week 1)".

As I said sprinkle a bit of benchmarks polluting the training and you have your loop. Each iteration will be better at benchmarks if that's the goal and that goal/context reinforces.

Sprinkling in benchmark training isn't a loop, it's just plain cheating. Regardless, not all of these benchmarks are public and, even with mass collusion across the board, it wouldn't make sense only open weight LLMS have been improving.
