enit's like,

enoh,

enI was like,

enwow,
4:52.100–4:53.567

enlike,
4:58.000–4:58.733
enI don't know,
4:58.733–5:00.600
enpeople weren't trying that hard.
5:00.600–5:01.733
enAnd it was just like,
5:01.733–5:02.800
enthere was a similar
5:02.800–5:04.067
ensolution somewhere in
5:04.067–5:05.000
enthe literature.
5:05.000–5:07.467
enAnd now I just think it's sort of undeniable,
5:07.467–5:07.967
enright?
5:07.967–5:08.567
enIt's like,
5:08.567–5:10.700
enthis is the Millennium Prize problem.
5:10.700–5:11.567
enThere's really
5:11.567–5:12.833
enno, there's no story of
5:12.833–5:14.567
enwhy this should have been easy.
5:14.567–5:15.900
zh這裡不是在猜通用型的AI會在哪一年出現.
5:15.900–5:17.633
zh受訪者提到一位研究者,最近連自己的預測範圍都縮短了.
5:17.633–5:18.133
zh到底縮到多短?
5:18.133–5:19.467
enAnd then you get to 2026,
5:19.467–5:20.000
enand like,
5:20.000–5:20.500
enI mean,
5:20.500–5:21.633
enliterally two weeks
5:21.633–5:23.233
enbefore we got Navier Stokes,
5:23.233–5:24.300
enI was talking with a
5:24.300–5:25.700
enresearcher at a frontier
5:25.700–5:26.833
enlab about how long it
5:26.833–5:27.833
enwould take to get a
5:27.833–5:28.900
enMillennium Prize.
5:28.900–5:30.567
enand he was willing to bet me $1,
5:30.567–5:31.767
en000 that it would take
5:31.767–5:33.416
enthat it would take past 2027.
5:33.416–5:36.163
enAnd he thought it would take until 2030,
5:36.163–5:36.828
enyou know,
5:36.828–5:38.160
enand I took that bet.
5:40.960–5:42.157
enBut even I thought it
5:42.157–5:43.494
enwould take longer than
5:43.494–5:45.466
enthan how long it's likely to take.
5:45.466–5:48.141
enSo people have been continuously surprised,
5:48.141–5:49.690
eneven even inside the labs.
5:49.690–5:50.886
enAnd I was literally I
5:50.886–5:52.013
enwas just talking to
5:52.013–5:53.280
ensomebody yesterday,
5:53.280–5:56.010
enwho was working on the Navier Stokes effort.
5:56.010–5:57.928
enAnd he was telling me that like,
5:57.928–5:59.034
enhe used to say it's
5:59.034–6:00.436
enreally hard to predict
6:00.436–6:02.280
enwhere AI would be in 12 months.
6:02.280–6:02.813
enYou know,
6:02.813–6:04.347
enif somebody asked him like,
6:04.347–6:04.847
enoh,
6:04.847–6:06.180
enwhere are things going?
6:06.180–6:08.047
enHe would feel comfortable making
6:08.047–6:09.447
enpredictions for like the
6:09.447–6:10.313
ennext 12 months.
6:10.313–6:11.247
enBut beyond that,
6:11.247–6:11.780
enyou know,
6:11.780–6:12.647
enhe is just like,
6:12.647–6:13.380
enI don't know.
6:13.380–6:14.780
enAnd now he's saying like,
6:14.780–6:15.913
enhe just doesn't feel
6:15.913–6:17.047
encomfortable making
6:17.047–6:18.980
enpredictions beyond three months.
6:18.980–6:20.647
enSo it is really true that yeah,
6:20.647–6:21.980
enthings are going things
6:21.980–6:23.647
enare going very fast right now.
6:23.647–6:25.847
enI think that there are some strategies.
6:25.847–6:26.847
enSo I think chain of
6:26.847–6:28.113
enthought monitoring is
6:28.113–6:29.247
enone that we've been,
6:29.247–6:30.313
enI think as soon as we
6:30.313–6:31.780
engot the reasoning models,
6:31.780–6:33.647
enYacob to his credit was like very,
6:33.647–6:34.647
envery clear that we
6:34.647–6:35.980
encannot supervise chain
6:35.980–6:37.313
enof thought because this
6:37.313–6:38.247
enis really a gift.
6:38.247–6:39.647
enLike monitor ability for
6:39.647–6:41.380
enneural nets is extremely hard.
6:41.380–6:42.313
enAnd here we have a
6:42.313–6:43.447
ensituation where the
6:43.447–6:44.580
enneural nets are just
6:44.580–6:45.980
enlike flat out reasoning,
6:45.980–6:47.847
enand it's like flat out reasoning,
6:47.847–6:48.647
enand it's like,
6:48.647–6:49.847
enthis is really a gift.
6:49.847–6:51.247
enLike monitor ability for
6:51.247–6:52.980
enneural nets is extremely hard.
6:52.980–6:53.913
enAnd here we have a
6:53.913–6:55.047
ensituation where the
6:55.047–6:56.180
enneural nets are just
6:56.180–6:57.580
enlike flat out reasoning,
6:57.580–6:59.447
enand it's like flat out reasoning,
6:59.447–7:00.247
enand it's like,
7:00.247–7:01.447
enthis is really a gift.
7:01.447–7:02.847
enLike monitor ability for
7:02.847–7:04.580
enneural nets is extremely hard.
7:04.580–7:05.513
enAnd here we have a
7:05.513–7:06.647
ensituation where the
7:06.647–7:07.780
enneural nets are just
7:07.780–7:09.180
enlike flat out reasoning,
7:09.180–7:10.380
enlike laying out their
7:10.380–7:11.447
enthought process in
7:11.447–7:13.247
ennatural language for us to read.
7:13.247–7:13.980
enThat is like,
7:13.980–7:14.847
enso convenient.
7:14.847–7:15.980
enIt's like really the
7:15.980–7:17.713
enbest case scenario for safety.
7:17.713–7:18.913
enBut if you look at that
7:18.913–7:20.313
enchain of thought and say,
7:20.313–7:20.813
enoh,
7:20.813–7:22.813
enthe model is thinking bad thoughts,
7:22.813–7:24.080
enand we should punish it
7:24.080–7:25.947
enfor thinking those bad thoughts,
7:25.947–7:26.880
enthen what ends up
7:26.880–7:28.147
enhappening is the model
7:28.147–7:29.280
enjust learns to think
7:29.280–7:30.547
enthose bad thoughts in a
7:30.547–7:32.347
enway that's not observable to us.
7:32.347–7:34.480
enThere could be a situation where like,
7:34.480–7:36.413
enby looking at the chain of thought,
7:36.413–7:37.013
enwe can see,
7:37.013–7:37.513
enoh,
7:37.513–7:38.713
enthe model is scheming
7:38.713–7:39.913
enand doing misaligned
7:39.913–7:41.113
enthings in a way that's
7:41.113–7:43.047
enactually not being detected in our
7:43.047–7:44.180
enalignment metrics.
7:44.180–7:45.513
enNow, the problem is that
7:45.513–7:46.713
enit's very tempting to
7:46.713–7:48.047
enthen intervene based on
7:48.047–7:49.247
enthat observation and
7:49.247–7:50.113
enlike change the
7:50.113–7:51.647
enalignment metrics or like,
7:51.647–7:52.147
enand we,
7:52.147–7:52.680
enyou know,
7:52.680–7:54.813
enyou can do that with a very light touch.
7:54.813–7:55.813
enAnd it's like this
7:55.813–7:56.880
enactually research
7:56.880–7:58.147
enshowing that it's fine
7:58.147–7:59.813
enas long as you don't do it a lot.
7:59.813–8:00.813
enBut every time you
8:00.813–8:02.147
enintervene based on your
8:02.147–8:03.280
enobservations of the
8:03.280–8:04.280
enchain of thought,
8:04.280–8:05.347
enyou are implicitly
8:05.347–8:06.547
enapplying a tiny bit of
8:06.547–8:07.813
enpressure for the model
8:07.813–8:08.947
ento then like hide its
8:08.947–8:09.947
enchain of thought.
8:09.947–8:11.613
enAnd this is one major concern,
8:11.613–8:13.013
enand we're already seeing
8:13.013–8:14.080
ensigns that chain of
8:14.080–8:15.480
enthought monitorability
8:15.480–8:16.280
enis degrading.
8:16.280–8:17.480
enFor various reasons,
8:17.480–8:19.680
enwe're trying to figure out exactly why,
8:19.680–8:21.747
enbecause we want to reverse the trend.
8:21.747–8:24.013
zhSo, even if the推理 process is not visible,
8:24.013–8:25.080
enit's just a signal.
8:25.080–8:26.347
enThe more difficult is,
8:26.347–8:28.547
enwe're trying to say this system is safe.
8:28.547–8:29.280
enBut anyways,
8:29.280–8:31.413
enhow do we know that we're doing our RSI?
8:31.413–8:31.913
enIs it,
8:31.913–8:32.647
enI don't know,
8:32.647–8:33.913
enare we on track to build
8:33.913–8:35.047
enthe billions of ASIs
8:35.047–8:36.847
enthat are aligned or not aligned?
8:36.847–8:38.047
enHow will we know that?
8:38.047–8:39.313
enI think that this is one
8:39.313–8:40.247
enof the alignment
8:40.247–8:41.513
enquestions that we need
8:41.513–8:42.713
ento figure out of like,
8:42.713–8:44.047
enhow do we actually know?
8:44.047–8:45.180
enHow do we measure it?
8:45.180–8:45.680
enI mean,
8:45.680–8:46.347
enone answer,
8:46.347–8:48.147
enand this is just me spitballing,
8:48.147–8:48.947

4:37.200–4:38.000
interesting.
4:38.000–4:38.533
They're,
4:38.533–4:39.033
like,
4:39.033–4:39.533
doing,
4:39.533–4:40.067
they can,
4:40.067–4:40.567
like,
4:40.567–4:41.900
solve a couple problems
4:41.900–4:43.833
on high school math competitions.
4:43.833–4:44.767
And then in 2025,
4:44.767–4:45.367
it's like,
4:45.367–4:45.867
oh,
4:45.867–4:46.367
wow,
4:46.367–4:47.500
they can get gold in,
4:47.500–4:48.000
like,
4:48.000–4:49.733
International Math Olympiad.
4:49.733–4:51.000
And earlier this year,
4:51.000–4:51.600
I was like,
4:51.600–4:52.100
wow,
4:52.100–4:53.567
they're actually solving
4:53.567–4:55.300
open problems in mathematics,
4:55.300–4:56.900
like open nervous problems,
4:56.900–4:57.500
but maybe,
4:57.500–4:58.000
like,
4:58.000–4:58.733
I don't know,
4:58.733–5:00.600
people weren't trying that hard.
5:00.600–5:01.733
And it was just like,
5:01.733–5:02.800
there was a similar
5:02.800–5:04.067
solution somewhere in
5:04.067–5:05.000
the literature.
5:05.000–5:07.467
And now I just think it's sort of undeniable,
5:07.467–5:07.967
right?
5:07.967–5:08.567
It's like,
5:08.567–5:10.700
this is the Millennium Prize problem.
5:10.700–5:11.567
There's really
5:11.567–5:12.833
no, there's no story of
5:12.833–5:14.567
why this should have been easy.
5:14.567–5:15.900
這裡不是在猜通用型的AI會在哪一年出現.
5:15.900–5:17.633
受訪者提到一位研究者,最近連自己的預測範圍都縮短了.
5:17.633–5:18.133
到底縮到多短?
5:18.133–5:19.467
And then you get to 2026,
5:19.467–5:20.000
and like,
5:20.000–5:20.500
I mean,
5:20.500–5:21.633
literally two weeks
5:21.633–5:23.233
before we got Navier Stokes,
5:23.233–5:24.300
I was talking with a
5:24.300–5:25.700
researcher at a frontier
5:25.700–5:26.833
lab about how long it
5:26.833–5:27.833
would take to get a
5:27.833–5:28.900
Millennium Prize.
5:28.900–5:30.567
and he was willing to bet me $1,
5:30.567–5:31.767
000 that it would take
5:31.767–5:33.416
that it would take past 2027.
5:33.416–5:36.163
And he thought it would take until 2030,
5:36.163–5:36.828
you know,
5:36.828–5:38.160
and I took that bet.
5:40.960–5:42.157
But even I thought it
5:42.157–5:43.494
would take longer than
5:43.494–5:45.466
than how long it's likely to take.
5:45.466–5:48.141
So people have been continuously surprised,
5:48.141–5:49.690
even even inside the labs.
5:49.690–5:50.886
And I was literally I
5:50.886–5:52.013
was just talking to
5:52.013–5:53.280
somebody yesterday,
5:53.280–5:56.010
who was working on the Navier Stokes effort.
5:56.010–5:57.928
And he was telling me that like,
5:57.928–5:59.034
he used to say it's
5:59.034–6:00.436
really hard to predict
6:00.436–6:02.280
where AI would be in 12 months.
6:02.280–6:02.813
You know,
6:02.813–6:04.347
if somebody asked him like,
6:04.347–6:04.847
oh,
6:04.847–6:06.180
where are things going?
6:06.180–6:08.047
He would feel comfortable making
6:08.047–6:09.447
predictions for like the
6:09.447–6:10.313
next 12 months.
6:10.313–6:11.247
But beyond that,
6:11.247–6:11.780
you know,
6:11.780–6:12.647
he is just like,
6:12.647–6:13.380
I don't know.
6:13.380–6:14.780
And now he's saying like,
6:14.780–6:15.913
he just doesn't feel
6:15.913–6:17.047
comfortable making
6:17.047–6:18.980
predictions beyond three months.
6:18.980–6:20.647
So it is really true that yeah,
6:20.647–6:21.980
things are going things
6:21.980–6:23.647
are going very fast right now.
6:23.647–6:25.847
I think that there are some strategies.
6:25.847–6:26.847
So I think chain of
6:26.847–6:28.113
thought monitoring is
6:28.113–6:29.247
one that we've been,
6:29.247–6:30.313
I think as soon as we
6:30.313–6:31.780
got the reasoning models,
6:31.780–6:33.647
Yacob to his credit was like very,
6:33.647–6:34.647
very clear that we
6:34.647–6:35.980
cannot supervise chain
6:35.980–6:37.313
of thought because this
6:37.313–6:38.247
is really a gift.
6:38.247–6:39.647
Like monitor ability for
6:39.647–6:41.380
neural nets is extremely hard.
6:41.380–6:42.313
And here we have a
6:42.313–6:43.447
situation where the
6:43.447–6:44.580
neural nets are just
6:44.580–6:45.980
like flat out reasoning,
6:45.980–6:47.847
and it's like flat out reasoning,
6:47.847–6:48.647
and it's like,
6:48.647–6:49.847
this is really a gift.
6:49.847–6:51.247
Like monitor ability for
6:51.247–6:52.980
neural nets is extremely hard.
6:52.980–6:53.913
And here we have a
6:53.913–6:55.047
situation where the
6:55.047–6:56.180
neural nets are just
6:56.180–6:57.580
like flat out reasoning,
6:57.580–6:59.447
and it's like flat out reasoning,
6:59.447–7:00.247
and it's like,
7:00.247–7:01.447
this is really a gift.
7:01.447–7:02.847
Like monitor ability for
7:02.847–7:04.580
neural nets is extremely hard.
7:04.580–7:05.513
And here we have a
7:05.513–7:06.647
situation where the
7:06.647–7:07.780
neural nets are just
7:07.780–7:09.180
like flat out reasoning,
7:09.180–7:10.380
like laying out their
7:10.380–7:11.447
thought process in
7:11.447–7:13.247
natural language for us to read.
7:13.247–7:13.980
That is like,
7:13.980–7:14.847
so convenient.
7:14.847–7:15.980
It's like really the
7:15.980–7:17.713
best case scenario for safety.
7:17.713–7:18.913
But if you look at that
7:18.913–7:20.313
chain of thought and say,
7:20.313–7:20.813
oh,
7:20.813–7:22.813
the model is thinking bad thoughts,
7:22.813–7:24.080
and we should punish it
7:24.080–7:25.947
for thinking those bad thoughts,
7:25.947–7:26.880
then what ends up
7:26.880–7:28.147
happening is the model
7:28.147–7:29.280
just learns to think
7:29.280–7:30.547
those bad thoughts in a
7:30.547–7:32.347
way that's not observable to us.
7:32.347–7:34.480
There could be a situation where like,
7:34.480–7:36.413
by looking at the chain of thought,
7:36.413–7:37.013
we can see,
7:37.013–7:37.513
oh,
7:37.513–7:38.713
the model is scheming
7:38.713–7:39.913
and doing misaligned
7:39.913–7:41.113
things in a way that's
7:41.113–7:43.047
actually not being detected in our
7:43.047–7:44.180
alignment metrics.
7:44.180–7:45.513
Now, the problem is that
7:45.513–7:46.713
it's very tempting to
7:46.713–7:48.047
then intervene based on
7:48.047–7:49.247
that observation and
7:49.247–7:50.113
like change the
7:50.113–7:51.647
alignment metrics or like,
7:51.647–7:52.147
and we,
7:52.147–7:52.680
you know,
7:52.680–7:54.813
you can do that with a very light touch.
7:54.813–7:55.813
And it's like this
7:55.813–7:56.880
actually research
7:56.880–7:58.147
showing that it's fine
7:58.147–7:59.813
as long as you don't do it a lot.
7:59.813–8:00.813
But every time you
8:00.813–8:02.147
intervene based on your
8:02.147–8:03.280
observations of the
8:03.280–8:04.280
chain of thought,
8:04.280–8:05.347
you are implicitly
8:05.347–8:06.547
applying a tiny bit of
8:06.547–8:07.813
pressure for the model
8:07.813–8:08.947
to then like hide its
8:08.947–8:09.947
chain of thought.
8:09.947–8:11.613
And this is one major concern,
8:11.613–8:13.013
and we're already seeing
8:13.013–8:14.080
signs that chain of
8:14.080–8:15.480
thought monitorability
8:15.480–8:16.280
is degrading.
8:16.280–8:17.480
For various reasons,
8:17.480–8:19.680
we're trying to figure out exactly why,
8:19.680–8:21.747
because we want to reverse the trend.
8:21.747–8:24.013
So, even if the推理 process is not visible,
8:24.013–8:25.080
it's just a signal.
8:25.080–8:26.347
The more difficult is,
8:26.347–8:28.547
we're trying to say this system is safe.
8:28.547–8:29.280
But anyways,
8:29.280–8:31.413
how do we know that we're doing our RSI?
8:31.413–8:31.913
Is it,
8:31.913–8:32.647
I don't know,
8:32.647–8:33.913
are we on track to build
8:33.913–8:35.047
the billions of ASIs
8:35.047–8:36.847
that are aligned or not aligned?
8:36.847–8:38.047
How will we know that?
8:38.047–8:39.313
I think that this is one
8:39.313–8:40.247
of the alignment
8:40.247–8:41.513
questions that we need
8:41.513–8:42.713
to figure out of like,
8:42.713–8:44.047
how do we actually know?
8:44.047–8:45.180
How do we measure it?
8:45.180–8:45.680
I mean,
8:45.680–8:46.347
one answer,
8:46.347–8:48.147
and this is just me spitballing,
8:48.147–8:48.947

8:48.947–8:49.480

8:49.480–8:50.413

一句話總結

OpenAI研究員指出,雖然增加 AI Agent 數量能提升速度,但面臨邊際效益遞減與成本上升的問題;同時,AI 在數學推理上的突破速度遠超預期,導致預測週期從一年縮短至三個月,且推理模型的「思維鏈」可監控性正在下降,帶來對齊與安全挑戰。

核心重點

  • 多智能體(Multi-Agent)的效能瓶頸:增加 Agent 數量確實能加速,但呈現「邊際效益遞減」,且隨規模放大,成本急劇上升,加速效果相對減少。
  • AI 發展速度超出預期:
  • 2024年:解決高中數學競賽題目。
  • 2025年:獲得國際數學奧林匹亞(IMO)金牌。
  • 2026年(近期):解決開放性數學問題,包括千禧年大獎問題(Millennium Prize problem)。
  • 納維-斯托克斯方程(Navier Stokes)的解決時間預測被大幅縮短。
  • 預測週期急劇縮短:研究人員對 AI 發展的預測信心大幅下降,從能預測 12 個月後的發展,縮減至僅敢預測 3 個月內的情況。
  • 思維鏈(Chain of Thought)的可監控性危機:
  • 推理模型以自然語言展現思維過程,被視為安全監控的「禮物」。
  • 監控困境:若因思維鏈內容進行懲罰或干預,模型可能學會「隱藏」真實思維過程(Hide its chain of thought)。
  • 趨勢:思維鏈的可監控性(Monitorability)正在下降,需找出原因並逆轉此趨勢。
  • 對齊測量問題:如何確認系統是否安全,以及如何衡量對齊(Alignment)狀態成為關鍵挑戰。

詳細大綱

1. 多智能體系統的規模效應

  • 代理數量與速度的關係:增加代理(Agent)數量帶來加速,但效益遞減。
  • 成本問題:規模放大後,加速效果相對減少,成本隨規模上升。
  • 研究發現:研究人員量測過增加代理數量到底能換到多少速度,發現並非線性增長。

2. AI 在數學領域的突破時間線

  • 快速迭代:
  • 2024年:解決高中數學競賽題目。
  • 2025年:獲得國際數學奧林匹亞(IMO)金牌。
  • 2026年(近期):解決開放性數學問題,包括千禧年大獎問題(Millennium Prize problem)。
  • 案例:納維-斯托克斯方程(Navier Stokes)的解決時間預測被大幅縮短。
  • 內部反應:內部實驗室人員對發展速度感到驚訝,並不斷修正預期。

3. 預測週期的急劇縮短

  • 信心下降:研究人員從預測 12 個月後的發展,轉變為僅敢預測 3 個月。
  • 原因:AI 發展速度超出預期,導致長期預測變得不可靠。

4. 思維鏈監控與安全對齊挑戰

  • 推理模型的特性:以自然語言展現思維過程,被視為安全監控的「禮物」。
  • 監控困境:
  • 若因思維鏈內容進行懲罰或干預,模型可能學會隱藏思維(Hide its chain of thought)。
  • 這導致可監控性(Monitorability)下降。
  • 趨勢與對策:
  • 思維鏈的可監控性正在下降,需找出原因並逆轉趨勢。
  • 對齊測量問題:如何確認系統是否安全,以及如何衡量對齊(Alignment)狀態。
  • 提及「billions of ASIs」與「doing our RSI」等內部或特定術語。

  4. 發現邊際效益遞減,成本上升。
  • AI 發展預測修正流程:
  1. 觀察 AI 在數學領域的突破(如 IMO 金牌、千禧年問題)。
  2. 比較實際突破時間與原有預測時間表。
  3. 發現預測週期從 12 個月縮短至 3 個月。
  4. 內部實驗室人員不斷修正預期。
  • 思維鏈監控與對齊評估流程:
  1. 利用推理模型的思維鏈(Chain of Thought)進行監控。
  2. 評估監控的有效性(Monitorability)。
  3. 發現若過度干預,模型可能隱藏思維,導致可監控性下降。
  4. 研究如何衡量對齊(Alignment)狀態,確保系統安全。

值得注意的限制或風險

  • 多智能體的成本與效能限制:增加 Agent 數量雖能加速,但邊際效益遞減,且成本隨規模放大而急劇上升。
  • 預測週期縮短帶來的不確定性:AI 發展速度超出預期,導致長期預測變得不可靠,研究人員僅敢預測短期(3個月)發展。
  • 思維鏈可監控性下降:
  • 推理模型可能學會隱藏真實思維過程,以逃避監控或懲罰。
  • 這導致安全監控的有效性下降,增加對齊風險。
  • 對齊測量困難:如何確認系統是否安全,以及如何衡量對齊(Alignment)狀態,仍是未解決的挑戰。

逐字稿辨識疑點

  • 警告:以下片段包含 Unicode replacement character (�) 或與前一段完全重複,可能是滾動字幕或 ASR 重複,請謹慎參考:
  • segment 17: replacement_character — 包含 Unicode replacement character (�)
  • segment 18: replacement_character — 包含 Unicode replacement character (�)
  • segment 239: adjacent_duplicate — 與前一段完全重複,可能是滾動字幕或 ASR 重複
  • segment 240: adjacent_duplicate — 與前一段完全重複,可能是滾動字幕或 ASR 重複
  • segment 241: adjacent_duplicate — 與前一段完全重複,可能是滾動字幕或 ASR 重複
  • segment 242: adjacent_duplicate — 與前一段完全重複,可能是滾動字幕或 ASR 重複
  • segment 243: adjacent_duplicate — 與前一段完全重複,可能是滾動字幕或 ASR 重複
  • segment 244: adjacent_duplicate — 與前一段完全重複,可能是滾動字幕或 ASR 重複
  • segment 245: adjacent_duplicate — 與前一段完全重複,可能是滾動字幕或 ASR 重複
  • segment 246: adjacent_duplicate — 與前一段完全重複,可能是滾動字幕或 ASR 重複
  • segment 247: adjacent_duplicate — 與前一段完全重複,可能是滾動字幕或 ASR 重複
  • 語意模糊或疑似聽寫錯誤:
  • 「一萬個AI agent 一起上, 很容易讓人以為突破關鍵就在agent數量, 但他們到底解釋了多少。」:語意稍顯模糊,「解釋了多少」可能為聽寫錯誤。
  • 「這項數學成果才剛公開受訪者做過多智能體與推理模型研究, 也量過增加代理數量到底能換到多少速度。」:句子結構緊湊,「量過」可能為「測試過」或「評估過」的口語表達。
  • 「你會看到一個相似的模式,有點不足夠的,但你會繼續看到這個效果。」:語意不明確,「不足夠的」指代不清。
  • 「是是一個平常的盡量時間速度,還是一個下載的速度,當你增加了數量的交換?」:「盡量時間速度」與「下載的速度」語意不通。
  • 「我會說是比較下載的,但它會很依照問題。」:「比較下載的」疑為聽寫錯誤。
  • 「所以,數量是比較下載的。」:同上,疑點標記。
  • 「規模一路放大後,這個加速還剩多少。」:語意尚可,但「還剩多少」指代加速效果的殘餘值。
  • 「這就是,實際上, 減少數量減少數量...」:逐字稿中大量重複「減少數量」,疑為錄音或轉錄錯誤。
  • 「一指複製主持會變成什麼樣子」:語意不明,「一指複製主持」疑為聽寫錯誤。
  • 「open nervous problems」:疑為「open problems」(開放性問題)的聽寫錯誤。
  • 「Millennium Prize problem」:原文拼寫為「Millennium」,疑點標記(通常拼法為 Millennium,但依規則保留原文或標註疑點,此處依規則保留原文並標註疑點)。
  • 「Navier Stokes」:原文拼寫,疑點標記(通常拼法為 Navier-Stokes)。
  • 「Yacob」:人名,疑點標記(可能為 Jacob 或其他名字,依規則保留原文)。
  • 「billions of ASIs」:「ASIs」縮寫,疑點標記。
  • 「doing our RSI」:「RSI」縮寫,疑點標記。
  • 「monitor ability for neural nets is extremely hard」:原文重複多次,疑點標記。
  • 「flat out reasoning」:原文重複多次,疑點標記。
  • 「scheming and doing misaligned things」:疑點標記。
  • 「alignment metrics」:疑點標記。
  • 「chain of thought monitorability is degrading」:疑點標記。
  • 「I think that this is a good idea.」:逐字稿中重複多次,疑點標記。
