the size-to-strength ratio is probably my favourite result from kibitzer. even more so because it came without rl, just supervised training, scaling the data, and search.
the blog goes through the architecture (including an ssm hypothesis), the final training recipe, how i evaluated the tournament elo, and the rl experiments that failed, along with what i think went wrong.
this plot isn’t a direct leaderboard since the ratings come from different evaluation pools, but the scale difference is still pretty interesting.
