pradheep(@pradheepraop):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. https://t.co/GgXnqKhci5 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.
