OpenAI suffers departure of yet another AI safety expert, and fresh claims around copyright infringement

On Wednesday, Miles Brundage—who had currently been leading a team charged with thinking about policies to help both the company and society at large prepare for the advent of “artificial general intelligence” or AGI—announced he was departing the company on Friday after more than six years so he could continue his work with fewer constraints.

In a lengthy Substack post, Brundage said OpenAI had placed increasingly restrictive limits on what he could say in published research. He also said that, by founding or joining an AI policy nonprofit, he hoped to become more effective in warning people of the urgency around AI’s dangers, as “claims to this effect are often dismissed as hype when they come from industry.”

‘The attention that safety deserves’

Brundage’s post did not take any overt swipes at his soon-to-be-former employer—indeed, he listed CEO Sam Altman as one of many people who provided “input on earlier versions of this draft”—but it did complain at length about AI companies in general “not necessarily [giving] AI safety and security the attention it deserves by default.”

“There are many reasons for this, one of which is a misalignment between private and societal interests, which regulation can help reduce. There are also difficulties around credible commitments to and verification of safety levels, which further incentivize corner-cutting,” Brundage wrote. “Corner-cutting occurs across a range of areas, including prevention of harmfully biased and hallucinated outputs as well as investment in preventing the catastrophic risks on the horizon.”

Brundage’s departure extends a string of high-profile resignations from OpenAI this year—including Mira Murati, its chief technology officer, as well as Ilya Sutskever, a cofounder of the company and its former chief scientist—many of which were either explicitly or likely related to the company’s shifting stance on AI safety.

OpenAI was initially founded as a research house for the development of safe AI, but over time the need for hefty outside funding—it recently raised a $6.6 billion round at a $157 billion valuation—has gradually tilted the scales toward its for-profit side, which is likely to soon formally become OpenAI’s dominant structural component.

Cofounders Sutskever and John Schulman both left OpenAI this year to boost their focus on safe AI. Sutskever founded his own company, and Schulman joined OpenAI archrival Anthropic, as did Jan Leike, a key colleague of Sutskever’s who declared that “over the past years, safety culture and processes [at OpenAI] have taken a back seat to shiny products.”

Already by August, it had become clear that around half of OpenAI’s safety-focused staff had departed in recent months—and that was before the dramatic exit of Murati, who frequently found herself having to adjudicate arguments between the firm’s safety-first researchers and its more gung-ho commercial team, as Fortune reported. For example, OpenAI’s staffers were given just nine days to test the safety of the firm’s powerful GPT-4o mode before its launch, according to sources familiar with the situation.

In a further sign of OpenAI’s shifting focus on safety, Brundage said that the AGI Readiness team he led is being disbanded, with its staff being “distributed among other teams.” Its economic research sub-team is becoming the responsibility of new OpenAI chief economist Ronnie Chatterji, he said. He did not specify how the other staff were being redeployed.

It is also worth noting that Brundage is not the first person at OpenAI to face problems over the research they wish to publish. After last year’s dramatic and short-lived ouster of Altman by OpenAI’s safety-focused board, it emerged that Altman had previously laid into then-board-member Helen Toner because she coauthored an AI safety paper that implicitly criticized the company.

Unsustainable model

Concerns about OpenAI’s culture and method were also heightened by another story on Wednesday. The New York Times carried a major piece on Suchir Balaji, an AI researcher who spent nearly four years at OpenAI before leaving in August.

Balaji says he left because he realized that OpenAI was breaking copyright law in the way it trained its models on copyrighted data from the web, and because he decided that chatbots like ChatGPT were more harmful than beneficial for society.

Again, OpenAI’s transmogrification from research outfit to money-spinner is central here. “With a research project, you can, generally speaking, train on any data. That was the mindset at the time,” Balaji told the Times. Now he claims that AI models threaten the commercial viability of the businesses that generated that data in the first place, saying: “This is not a sustainable model for the internet ecosystem as a whole.”

OpenAI and many of its peers have been sued by copyright holders over that training, which involved copying seas of data so that the companies’ systems could ingest and learn from it. Those AI models are not thought to contain whole copies of the data as such, and they rarely output close copies in response to users’ prompts—it’s the initial, unauthorized copying that the suits are generally targeting.

The standard defense in such cases is for companies accused of violating copyright to argue that the way they are using copyrighted works should constitute “fair use”—that copyright was not infringed because the companies transformed the copyrighted works into something else, in a nonexploitative way; used them in a way that did not directly compete with the original copyright holders or prevent them from possibly exploiting the work in a similar fashion or that served the public interest. The defense is easier to apply to noncommercial use cases—and is always decided by judges on a case by case basis.

In a Wednesday blog post, Balaji dove into the relevant U.S. copyright law and assessed how its tests for establishing “fair use” related to OpenAI’s data practices. He alleged that the advent of ChatGPT had negatively affected traffic to destinations like the developer Q&A site Stack Overflow, saying ChatGPT’s output could in some cases substitute for the information found on that site. He also presented mathematical reasoning that, he claimed, could be used to determine links between an AI model’s output and its training data.

Balaji is a computer scientist and not a lawyer. And there are plenty of copyright lawyers who do think a fair use defense of using copyrighted works in the training of AI models should be successful. However, Balaji’s intervention will no doubt catch the attention of the lawyers representing the publishers and book authors that have sued OpenAI for copyright infringement. It seems likely that his insider analysis will end up playing some role in these cases, the outcome of which could determine the future economics of generative AI, and possibly the futures of companies such as OpenAI.

It is rare for AI companies’ employees to go public with their concerns over copyright. Until now, the most significant case has probably been that of Ed Newton-Rex, who was head of audio at Stability AI before quitting last November with the claim that “today’s generative AI models can clearly be used to create works that compete with the copyrighted works they are trained on, so I don’t see how using copyrighted works to train generative AI models of this nature can be considered fair use.”

“We build our AI models using publicly available data, in a manner protected by fair use and related principles, and supported by long-standing and widely accepted legal precedents,” an OpenAI spokesperson said in a statement. “We view this principle as fair to creators, necessary for innovators, and critical for U.S. competitiveness.”

‘Excited to follow its impact’

Meanwhile, OpenAI’s spokesperson said Brundage’s “plan to go all in on independent research on AI policy gives him the opportunity to have an impact on a wider scale, and we are excited to learn from his work and follow its impact.”

“We’re confident that in his new role, Miles will continue to raise the bar for the quality of policymaking in industry and government,” they said.

Brundage had seen the scope of his job at OpenAI narrowed over his career with the company, going from the development of AI safety testing methodologies and research into current national and international governance issues related to AI to an exclusive focus on the handling of a potential superhuman AGI, rather than AI’s near-term safety risks.

Meanwhile, OpenAI has hired a growing cast of heavy-hitting policy experts, many with extensive political, national security, or diplomatic experience, to head teams looking at various aspects of AI governance and policy. It hired Anna Makanju, a former Obama administration national security official who had worked in policy roles at SpaceX’s Starlink and Facebook, to oversee its initial outreach to government officials both in Washington, D.C., and around the globe. She is currently OpenAI’s vice president of global impact. More recently, it brought in veteran political operative Chris Lehane, who had also been in a communications and policy role at Airbnb, to be its vice president of global affairs. Chatterji, who is taking over the economics team that formerly reported to Brundage, formerly worked in various advisory roles in President Joe Biden’s and President Barack Obama’s White Houses and also served as chief economist at the Department of Commerce.

It is not uncommon at fast-growing technology companies to see early employees have their roles circumscribed by the later addition of senior staff. In Silicon Valley, this is often referred to as “getting layered.” And, although it is not explicitly mentioned in Brundage’s blog post, it may be that the loss of his economic unit to Chatterji, coming after the previous loss of some of his near-term AI policy research to Makanju and Lehane, was a final straw. Brundage did not immediately respond to requests for comment for this story.

Brundage used his post to set out the issues on which he will now focus. These include assessing and forecasting AI progress; the regulation of frontier AI safety and security; AI’s economic impacts; the acceleration of positive use cases for AI; policy around the distribution of AI hardware; and the high-level “overall AI grand strategy.”

He warned that “neither OpenAI nor any other frontier lab” was really ready for the advent of AGI, nor was the outside world. “To be clear, I don’t think this is a controversial statement among OpenAI’s leadership,” he stressed, before arguing that people should still go work at the company as long as they “take seriously the fact that their actions and statements contribute to the culture of the organization, and may create positive or negative path dependencies as the organization begins to steward extremely advanced capabilities.”

Brundage noted that OpenAI had offered him funding, compute credits, and even early model access to aid his upcoming work.

However, he said he still hadn’t decided whether to take up those offers, as they “may compromise the reality and/or perception of independence.”
