At the end of last year, we're like, all right, we are quite excited about the progress.
2
We haven't seen the models yet.
3
It's like, I'm going to write this check for, I don't know, like $100 billion or $200 billion.
4
I'm like, Alex, are you sure this is going to work?
5
It was so extreme that we had the whole exec team.
6
I think Susan scared you a bit.
7

8
yeah, and we hope it's all going to work and be good.
9
But there were literally, like the end of last year, other than me giving a vibe report or how our research was going
10
and it could sort of show some plots and whatnot.
11
But it was like, I mean, I was feeling good about it, but it was certainly not clear at all that it was going to work.
12
You guys are saying
13
that the essence of training a frontier model is you have to push your chips all in before
14
you've been dealt the cards.
15
You just have to decide that you're going to develop a frontier model and you don't get to meter the investment.
16
At this scale.
17
I mean, back a few years ago, the clusters didn't have to be this big, but now they do.
18
So I think this is part of the excitement of brooding up a frontier lab
19
now is basically like the ante is extremely high.

シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
