00:04
So I've been an AI researcher for over a decade.
0
4292
3504
00:07
And a couple of months ago, I got the weirdest email of my career.
1
7796
3503
00:11
A random stranger wrote to me
2
11925
1668
00:13
saying that my work in AI is going to end humanity.
3
13635
3420
00:18
Now I get it, AI, it's so hot right now.
4
18598
3754
00:22
(Laughter)
5
22352
1627
00:24
It's in the headlines pretty much every day,
6
24020
2086
00:26
sometimes because of really cool things
7
26106
1918
00:28
like discovering new molecules for medicine
8
28066
2169
00:30
or that dope Pope in the white puffer coat.
9
30235
2252
00:33
But other times the headlines have been really dark,
10
33446
2461
00:35
like that chatbot telling that guy that he should divorce his wife
11
35907
3671
00:39
or that AI meal planner app proposing a crowd pleasing recipe
12
39619
4088
00:43
featuring chlorine gas.
13
43707
2002
00:46
And in the background,
14
46376
1418
00:47
we've heard a lot of talk about doomsday scenarios,
15
47836
2419
00:50
existential risk and the singularity,
16
50255
1918
00:52
with letters being written and events being organized
17
52215
2503
00:54
to make sure that doesn't happen.
18
54718
2002
00:57
Now I'm a researcher who studies AI's impacts on society,
19
57637
4630
01:02
and I don't know what's going to happen in 10 or 20 years,
20
62267
2836
01:05
and nobody really does.
21
65145
2461
01:07
But what I do know is that there's some pretty nasty things going on right now,
22
67981
4546
01:12
because AI doesn't exist in a vacuum.
23
72527
2878
01:15
It is part of society, and it has impacts on people and the planet.
24
75447
3920
01:20
AI models can contribute to climate change.
25
80160
2502
01:22
Their training data uses art and books created by artists
26
82704
3462
01:26
and authors without their consent.
27
86207
1710
01:27
And its deployment can discriminate against entire communities.
28
87959
3837
01:32
But we need to start tracking its impacts.
29
92797
2127
01:34
We need to start being transparent and disclosing them and creating tools
30
94966
3587
01:38
so that people understand AI better,
31
98595
2419
01:41
so that hopefully future generations of AI models
32
101056
2335
01:43
are going to be more trustworthy, sustainable,
33
103433
2836
01:46
maybe less likely to kill us, if that's what you're into.
34
106269
2836
01:50
But let's start with sustainability,
35
110148
1752
01:51
because that cloud that AI models live on is actually made out of metal, plastic,
36
111900
5756
01:57
and powered by vast amounts of energy.
37
117656
2460
02:00
And each time you query an AI model, it comes with a cost to the planet.
38
120116
4463
02:05
Last year, I was part of the BigScience initiative,
39
125789
3044
02:08
which brought together a thousand researchers
40
128833
2127
02:10
from all over the world to create Bloom,
41
130960
2503
02:13
the first open large language model, like ChatGPT,
42
133505
4337
02:17
but with an emphasis on ethics, transparency and consent.
43
137842
3546
02:21
And the study I led that looked at Bloom's environmental impacts
44
141721
3253
02:25
found that just training it used as much energy
45
145016
3253
02:28
as 30 homes in a whole year
46
148311
2211
02:30
and emitted 25 tons of carbon dioxide,
47
150563
2419
02:33
which is like driving your car five times around the planet
48
153024
3253
02:36
just so somebody can use this model to tell a knock-knock joke.
49
156319
3170
02:39
And this might not seem like a lot,
50
159489
2169
02:41
but other similar large language models,
51
161700
2460
02:44
like GPT-3,
52
164202
1126
02:45
emit 20 times more carbon.
53
165370
2544
02:47
But the thing is, tech companies aren't measuring this stuff.
54
167956
2878
02:50
They're not disclosing it.
55
170875
1252
02:52
And so this is probably only the tip of the iceberg,
56
172168
2461
02:54
even if it is a melting one.
57
174629
1418
02:56
And in recent years we've seen AI models balloon in size
58
176798
3629
03:00
because the current trend in AI is "bigger is better."
59
180468
3462
03:04
But please don't get me started on why that's the case.
60
184305
2795
03:07
In any case, we've seen large language models in particular
61
187100
3003
03:10
grow 2,000 times in size over the last five years.
62
190103
3211
03:13
And of course, their environmental costs are rising as well.
63
193314
3045
03:16
The most recent work I led, found that switching out a smaller,
64
196401
3795
03:20
more efficient model for a larger language model
65
200238
3337
03:23
emits 14 times more carbon for the same task.
66
203616
3754
03:27
Like telling that knock-knock joke.
67
207412
1877
03:29
And as we're putting in these models into cell phones and search engines
68
209289
3462
03:32
and smart fridges and speakers,
69
212792
2836
03:35
the environmental costs are really piling up quickly.
70
215628
2628
03:38
So instead of focusing on some future existential risks,
71
218840
3754
03:42
let's talk about current tangible impacts
72
222635
2753
03:45
and tools we can create to measure and mitigate these impacts.
73
225388
3629
03:49
I helped create CodeCarbon,
74
229893
1668
03:51
a tool that runs in parallel to AI training code
75
231603
2961
03:54
that estimates the amount of energy it consumes
76
234564
2211
03:56
and the amount of carbon it emits.
77
236775
1668
03:58
And using a tool like this can help us make informed choices,
78
238485
2877
04:01
like choosing one model over the other because it's more sustainable,
79
241404
3253
04:04
or deploying AI models on renewable energy,
80
244657
2920
04:07
which can drastically reduce their emissions.
81
247619
2544
04:10
But let's talk about other things
82
250163
2085
04:12
because there's other impacts of AI apart from sustainability.
83
252290
2961
04:15
For example, it's been really hard for artists and authors
84
255627
3128
04:18
to prove that their life's work has been used for training AI models
85
258797
4212
04:23
without their consent.
86
263051
1209
04:24
And if you want to sue someone, you tend to need proof, right?
87
264302
3170
04:27
So Spawning.ai, an organization that was founded by artists,
88
267806
3920
04:31
created this really cool tool called “Have I Been Trained?”
89
271726
3337
04:35
And it lets you search these massive data sets
90
275104
2461
04:37
to see what they have on you.
91
277607
2085
04:39
Now, I admit it, I was curious.
92
279734
1668
04:41
I searched LAION-5B,
93
281444
1627
04:43
which is this huge data set of images and text,
94
283112
2461
04:45
to see if any images of me were in there.
95
285615
2711
04:49
Now those two first images,
96
289285
1585
04:50
that's me from events I've spoken at.
97
290870
2169
04:53
But the rest of the images, none of those are me.
98
293081
2753
04:55
They're probably of other women named Sasha
99
295875
2002
04:57
who put photographs of themselves up on the internet.
100
297919
2628
05:01
And this can probably explain why,
101
301047
1627
05:02
when I query an image generation model
102
302715
1836
05:04
to generate a photograph of a woman named Sasha,
103
304551
2294
05:06
more often than not I get images of bikini models.
104
306886
2753
05:09
Sometimes they have two arms,
105
309681
1626
05:11
sometimes they have three arms,
106
311349
2294
05:13
but they rarely have any clothes on.
107
313685
2043
05:16
And while it can be interesting for people like you and me
108
316563
2794
05:19
to search these data sets,
109
319357
2127
05:21
for artists like Karla Ortiz,
110
321526
2044
05:23
this provides crucial evidence that her life's work, her artwork,
111
323570
3753
05:27
was used for training AI models without her consent,
112
327365
2961
05:30
and she and two artists used this as evidence
113
330326
2336
05:32
to file a class action lawsuit against AI companies
114
332704
2794
05:35
for copyright infringement.
115
335540
1960
05:37
And most recently --
116
337542
1168
05:38
(Applause)
117
338710
3378
05:42
And most recently Spawning.ai partnered up with Hugging Face,
118
342130
3044
05:45
the company where I work at,
119
345216
1585
05:46
to create opt-in and opt-out mechanisms for creating these data sets.
120
346801
4922
05:52
Because artwork created by humans shouldn’t be an all-you-can-eat buffet
121
352098
3587
05:55
for training AI language models.
122
355727
1793
05:58
(Applause)
123
358313
4254
06:02
The very last thing I want to talk about is bias.
124
362567
2336
06:04
You probably hear about this a lot.
125
364944
1919
06:07
Formally speaking, it's when AI models encode patterns and beliefs
126
367196
3713
06:10
that can represent stereotypes or racism and sexism.
127
370950
3128
06:14
One of my heroes, Dr. Joy Buolamwini, experienced this firsthand
128
374412
3212
06:17
when she realized that AI systems wouldn't even detect her face
129
377665
3045
06:20
unless she was wearing a white-colored mask.
130
380752
2169
06:22
Digging deeper, she found that common facial recognition systems
131
382962
3754
06:26
were vastly worse for women of color compared to white men.
132
386758
3253
06:30
And when biased models like this are deployed in law enforcement settings,
133
390428
5297
06:35
this can result in false accusations, even wrongful imprisonment,
134
395767
4296
06:40
which we've seen happen to multiple people in recent months.
135
400063
3920
06:44
For example, Porcha Woodruff was wrongfully accused of carjacking
136
404025
3086
06:47
at eight months pregnant
137
407111
1252
06:48
because an AI system wrongfully identified her.
138
408363
2961
06:52
But sadly, these systems are black boxes,
139
412325
2002
06:54
and even their creators can't say exactly why they work the way they do.
140
414369
5964
07:00
And for example, for image generation systems,
141
420917
3462
07:04
if they're used in contexts like generating a forensic sketch
142
424379
4129
07:08
based on a description of a perpetrator,
143
428549
2711
07:11
they take all those biases and they spit them back out
144
431260
3587
07:14
for terms like dangerous criminal, terrorists or gang member,
145
434889
3462
07:18
which of course is super dangerous
146
438393
2168
07:20
when these tools are deployed in society.
147
440603
4421
07:25
And so in order to understand these tools better,
148
445566
2294
07:27
I created this tool called the Stable Bias Explorer,
149
447902
3212
07:31
which lets you explore the bias of image generation models
150
451155
3379
07:34
through the lens of professions.
151
454575
1669
07:37
So try to picture a scientist in your mind.
152
457370
3045
07:40
Don't look at me.
153
460456
1168
07:41
What do you see?
154
461666
1335
07:43
A lot of the same thing, right?
155
463835
1501
07:45
Men in glasses and lab coats.
156
465378
2377
07:47
And none of them look like me.
157
467797
1710
07:50
And the thing is,
158
470174
1460
07:51
is that we looked at all these different image generation models
159
471676
3253
07:54
and found a lot of the same thing:
160
474929
1627
07:56
significant representation of whiteness and masculinity
161
476597
2586
07:59
across all 150 professions that we looked at,
162
479225
2127
08:01
even if compared to the real world,
163
481352
1794
08:03
the US Labor Bureau of Statistics.
164
483187
1836
08:05
These models show lawyers as men,
165
485023
3044
08:08
and CEOs as men, almost 100 percent of the time,
166
488109
3462
08:11
even though we all know not all of them are white and male.
167
491571
3170
08:14
And sadly, my tool hasn't been used to write legislation yet.
168
494782
4380
08:19
But I recently presented it at a UN event about gender bias
169
499203
3963
08:23
as an example of how we can make tools for people from all walks of life,
170
503166
3879
08:27
even those who don't know how to code,
171
507086
2252
08:29
to engage with and better understand AI because we use professions,
172
509380
3253
08:32
but you can use any terms that are of interest to you.
173
512633
3087
08:36
And as these models are being deployed,
174
516596
2752
08:39
are being woven into the very fabric of our societies,
175
519390
3128
08:42
our cell phones, our social media feeds,
176
522518
2044
08:44
even our justice systems and our economies have AI in them.
177
524604
3211
08:47
And it's really important that AI stays accessible
178
527815
3879
08:51
so that we know both how it works and when it doesn't work.
179
531736
4713
08:56
And there's no single solution for really complex things like bias
180
536908
4296
09:01
or copyright or climate change.
181
541245
2419
09:03
But by creating tools to measure AI's impact,
182
543664
2711
09:06
we can start getting an idea of how bad they are
183
546375
3337
09:09
and start addressing them as we go.
184
549754
2502
09:12
Start creating guardrails to protect society and the planet.
185
552256
3337
09:16
And once we have this information,
186
556177
2336
09:18
companies can use it in order to say,
187
558513
1835
09:20
OK, we're going to choose this model because it's more sustainable,
188
560389
3170
09:23
this model because it respects copyright.
189
563601
2044
09:25
Legislators who really need information to write laws,
190
565686
3087
09:28
can use these tools to develop new regulation mechanisms
191
568773
3462
09:32
or governance for AI as it gets deployed into society.
192
572276
3796
09:36
And users like you and me can use this information
193
576114
2377
09:38
to choose AI models that we can trust,
194
578491
3337
09:41
not to misrepresent us and not to misuse our data.
195
581869
