Artificial intelligence tools like ChatGPT are incredible at answering questions, solving problems, and generating creative content.
But they are not immune to flaws.
One area of concern is adversarial attacks—an issue OpenAI is now addressing in a groundbreaking research paper titled “Trading Inference-Time Compute for Adversarial Robustness.”
What are adversarial attacks and why do they matter?
Adversarial attacks exploit weaknesses in AI models. In simple terms, attackers can input carefully crafted data to trick an AI system into making errors or behaving in unintended ways.

For example, an AI that is normally good at recognising objects might mistake a cat for a dog because of subtle alterations to the image.
When it comes to language models like ChatGPT, adversarial attacks could involve tweaking inputs to make the system respond inaccurately, unethically, or even dangerously.
This is not just a technical issue—it’s a security and trust problem for the technology millions rely on.
How OpenAI is tackling the problem
In their latest research, OpenAI explored a new approach to fortify language models against these kinds of attacks.
The focus? Striking a balance between model performance and its resilience to adversarial manipulation.
The researchers proposed trading some speed during inference (the process when the AI generates responses) to make models more robust.
This involves using additional computational resources to analyse inputs more thoroughly and identify potential threats before they lead to mistakes.
Their methods included:
- Ensembling Models: Running multiple slightly different versions of a model to cross-check outputs.
- Iterative Refinement: Adding layers of checks to better evaluate complex inputs.
- Time vs Robustness Tradeoff: Slowing down responses slightly to improve their quality and resistance to manipulation.
The findings show promising results: the models became harder to fool without drastically affecting their usefulness for regular users.
By addressing adversarial attacks, OpenAI is working to make AI safer, more reliable, and better equipped to handle tricky or harmful inputs.
For everyday users, this means a more trustworthy tool that can perform complex tasks without being derailed by bad actors.
