Research lab
OpenAI, which started as a nonprofit with the goal of mitigating the potential
harms of artificial intelligence, has announced its first commercial product:
an AI textgeneration system that the outfit previously warned was too dangerous
to share.
OpenAI’s
work on text generation attracted much acclaim after the lab published the text
generator GPT-2 in February last year. The project was widely seen as a
significant step forward in the field. Users can input any text prompt into
GPT-2 — a few lines of a song, a short story, even a scientific paper — and the
software will continue writing, matching the style and content to some degree.
You can try a web version of GPT-2 for yourself here. OpenAI initially limited
the release of GPT-2 due to concerns the system would be used for malicious
purposes, like the mass-generation of fake news or spam. It later published the
code in full, saying it had seen “no strong evidence of misuse.” This year, it
announced a more sophisticated version of the system, 100 times larger, named
GPT-3, which it’s now adapted into its first commercial product.
Access to
the GPT-3 API is invitation-only, and pricing is undecided. It’s also not
clear, even to OpenAI itself, exactly how the system might be used. The API
could be used to improve the fluency of chatbots, to create new gaming
experiences, and much more besides.
AI text
generators like GPT-3 work by analyzing a huge corpus of text, and learning to
predict what letters and words tend to follow after one another. This sounds
like a simple learning approach, but it produces software that is incredibly
flexible and varied. GPT-2, for example, has been used to create a range of
tools, from chatbots to text-based dungeon generators. And because it learns
how to generate data simply by looking for past patterns, it can even be tuned
to play chess and solve math problems, given the right training.
So far,
OpenAI says the GPT-3 API has around a dozen users. These include the search
provider Algolia, which is using the API to better understand natural language
search queries; mental health platform Koko, which is using it to analyze when
users are in “crisis”; and Replika, which builds “AI companions.” Social media
platform Reddit is also exploring how the GPT-3 API might be used to help it
automate content moderation.
OpenAI says,
as with the initial launch of GPT-2, it’s taking things slowly and keeping an
eye out for malicious use cases before it makes the API available to all. “I
don’t know exactly how long that will take,” OpenAI CEO Sam Altman told
Bloomberg. “We would rather be on the too-slow than the too-fast side. We will
mistakes here, and we will learn.”
News of the
API’s release is notable not only as a step forward for a promising field in
machine learning, but also as a milestone in OpenAI’s history as a company.
