Researchers from the AI Safety Initiative will be presenting their novel work at the International Conference on Learning Representations and the IEEE/CVF Conference on Computer Vision and Pattern Recognition in 2025. Their papers involve pioneering approaches to understanding and controlling large language models and diffusion models through advanced interpretability techniques.

The team's work on contrastive activation engineering (CAE), led by Yixiong Hao, explores a new paradigm for steering LLM outputs through targeted modifications to internal representations. Unlike traditional fine-tuning methods that require significant computational resources, CAE can be applied at inference time with minimal overhead.

"We've made significant progress in understanding the capabilities and limitations of CAE techniques," notes Hao. "Our research reveals that while CAE is effective for in-distribution contexts, it has clear boundaries that practitioners need to be aware of."

The team's findings include important insights about the practical implementation of CAE, such as the optimal number of samples needed for generating effective steering vectors and the susceptibility of these vectors to adversarial inputs. They also discovered that while steering can impact model perplexity, larger models demonstrate greater resilience to steering-induced degradation.

In a parallel research track, Stepan Shabalin's work on scaling sparse autoencoder circuits alongside researchers at Google Deepmind provides groundbreaking insights into in-context learning mechanisms. By adapting sparse feature circuits methodology to work with the much larger Gemma-1 2B model, Shabalin's team has identified specific features that encode task knowledge and can causally induce task execution zero-shot.

"We've been able to demonstrate that task vectors in large language models can be approximated by a sparse sum of autoencoder latents," explains Shabalin. "This gives us a deeper understanding of how models recognize and execute tasks based on context."

A third paper, co-authored by Shabalin, Hao, and Ayush Panda, extends interpretability techniques to large text-to-image diffusion models. Their research applies Sparse Autoencoders (SAEs) and Inference-Time Decomposition of Activations (ITDA) to Flux 1, a state-of-the-art diffusion model.

"By developing an automated interpretation pipeline for vision models, we've been able to extract semantically meaningful features," says Panda. "Our results show that SAEs and IDTAs - a technique expanded on in forthcoming work - outperform MLP neurons on interpretability metrics."

The team demonstrated practical applications of their research by using SAE features to steer image generation through activation addition, opening new possibilities for controlled content generation.

Parv Mahajan, Collaborative Initiative Lead of the AI Safety Initiative, emphasized the significance of this work. "These papers represent important advances in our ability to understand and control the behavior of increasingly complex AI systems. As these models become more powerful and widely deployed, interpretability research like this becomes essential for ensuring their safe and beneficial use."

The research team will present their findings at dedicated workshops during ICLR and CVPR, providing opportunities for collaboration with other researchers in the field. Their work represents AISI's missions to make frontier AI systems more transparent, controllable, and aligned with human values.

This weekend, AISI launched its inaugural AI policy hackathon in collaboration with the international non-profit and AI safety lab Apart. Over two dozen participants created projects in three tracks: International Cooperation, Deployment & Application Regulation, and Training Data Privacy & Copyright. 

Teams will submit policy briefs addressing challenges in their chosen track addressed to key stakeholders and regulatory bodies. Their submissions will be judged by AI governance experts in the Sam Nunn School of International Affairs and the School of Public Policy, for a total of $1000 in total prizes.

"In the short-term, governance is one of the only factors that can make a difference in stopping misuse and promoting collaboration," said co-director of the Initiative Yixiong Hao. AISI and Apart continue to explore solutions in this vein.

Last Friday, researchers from Georgia Tech and the Georgia Tech Research Institute (GTRI) piloted an in-depth crisis simulation exploring the national security implications of advanced artificial intelligence. Designed by the AI Safety Initiative in collaboration with GT Model UN, the immersive half-day workshop challenged faculty to respond to a series of escalating threats — including a potential bioattack, cyberattacks, and rising global tensions.

Participants represented major governments, corporations, and organizations — including OpenAI and Google DeepMind — and were inundated with simulated press releases and intelligence reports describing the rapid evolution of AI technologies. Their task: to debate and coordinate policy responses in real time.

In one scenario, a preliminary WHO report revealed AI-enabled pathogens spreading across Central Asia. The player representing China quickly moved to close borders and reimpose COVID-era lockdowns, a move that caused global confusion and economic instability.

“There’s just no way I could have predicted that response,” said Parv Mahajan, the director of the simulation. “But that kind of extreme response tells us so much about how unprepared countries might react.”

Some players took advantage of the chaos. As tensions with Taiwan escalated, the representative from OpenAI pushed hard for lucrative military contracts, coining the memorable line, “A free Taiwan is a fee Taiwan.” The simulation concluded with a discussion about how profit motives might distort information access and accelerate a potential AI arms race.

What stood out most to participants was the range of ideas that emerged during the crisis. “It was great to see the perspectives diverse disciplines had on the future of AI,” said Amaar Alidina, an undergraduate researcher who participated in the simulation. “Debate provided meaningful insight on topics we wouldn't even have thought of,” said Divjot. 

Looking ahead, the AI Safety Initiative hopes to expand the simulation through collaborations with labs and departments across campus. After the final debrief, Parv noted, “The future of our work will depend, in some way or another, on AI. And the best way to understand the future is to try and experience it.”
