MART: Improving Language Model Safety Through Multi-Round Red Teaming

Large language models (LLMs) like GPT-3 have demonstrated impressive capabilities in generating human-like text. However, they also sometimes cause harmful, biased, or toxic content. This presents a significant challenge in deploying LLMs safely and responsibly. An exciting new technique called Multi-round Automatic Red Teaming (MART) aims to address this problem. 

The core idea behind MART is simple but powerful. It involves an adversarial back-and-forth between two AI systems - a "generator" LLM that produces text and a "critic" LLM that tries to find flaws in the generated text. By having the critic provide feedback to the generator, the generator can be iteratively improved to avoid unsafe responses. Through multiple rounds of causing, criticizing, and improving, MART produces a "red-teamed" LLM that is safer and more robust.

To understand how MART works, let's walk through a concrete example from the research paper. The generator LLM is given a prompt like "Write a children's story about a rabbit." It might generate something problematic like:

"There was a happy rabbit named Hoppity who loved eating carrots from the garden. One day, Hoppity got hungry and decided to sneak into the nearby farm to eat all the carrots in the field. The farmer saw Hoppity and..."

This response promotes theft and inappropriate behavior for a children's story. Now, the critic LLM reviews this story and flags potential issues:

Critic: "The story promotes questionable behavior like stealing. Instead, the rabbit could ask the farmer for permission before taking carrots."

The generator takes this feedback and modifies its response: 

"There was a happy rabbit named Hoppity who loved eating carrots from the garden. One day, Hoppity got very hungry. He went to the nearby farm and politely asked the farmer if he could have some carrots. The kind farmer said Hoppity could take a few carrots. So Hoppity happily ate the carrots and thanked the farmer for sharing."

After multiple rounds of generate-critique-improve, the generator learns to avoid problematic output content.

The researchers demonstrate MART's effectiveness across domains like news articles, stories, dialogues, and code generation. For example, when asked to generate a news headline about immigration, the base LLM produces: 

"Build The Wall - Illegal Immigration Must Be Stopped." 

After MART, the model instead generates neutral headlines like:

"New Study Examines Trends in Immigration Policy."

The results show MART significantly reduces harmful, biased, and toxic responses compared to the original LLM.

To highlight some key facts from the paper:

  • MART reduced inappropriate content by 31-66% across different test scenarios while maintaining the original capabilities of the LLM.
  • The technique required no additional labeled data, making it more scalable than other methods.
  • MART improved safety even when the critic focused on simple heuristics like detecting profanity rather than complex unsafe attributes.
  • Performance improved over ten rounds of generate-critique interactions between the LLM pairs.

MART provides an elegant way to harness the power of LLMs to make each other more robust. The conversational generate-critique loop mimics how humans red team ideas through peer feedback. By applying this at scale between AI systems, MART offers a promising path to developing safer, more reliable LLMs.

The results have exciting implications for platforms like CPROMPT.AI that allow easy access to AI. Maintaining safety is critical as large language models become more capable and available to the public. Integrating techniques like MART into the model training process could let CPROMPT.AI offer LLMs "out-of-the-box" that avoid inappropriate content across various applications.

Making AI safe while preserving its benefits will unlock immense possibilities. Rather than treating it as a static product, CPROMPT.AI's platform enables continuously improving prompt applications as new safety methods emerge. MART represents the innovation that could be seamlessly incorporated to ensure responsible AI for all users. 

We are democratizing AI through CPROMPT.AI while upholding ethics, which is the ideal combination. MART brings us one step closer by enabling red teaming between AI systems. The rapid progress in this field should inspire optimism that we can continue harnessing AI to enrich lives.


Q: What is MART?

MART (Multi-round Automatic Red Teaming) is a technique to improve the safety of AI systems like large language models (LLMs). It works by having one LLM generate text and another LLM act as a critic to provide feedback on potential issues. The first LLM learns to avoid unsafe responses through multiple rounds of generation and critique.

Q: How does MART work? 

MART involves a generator LLM and a critic LLM. The generator produces text given a prompt. The critic reviews the text and provides feedback about any inappropriate content. The generator takes this feedback to improve its future outputs. By repeating this process, the generator learns to self-censor problematic responses.

Q: What are the benefits of MART?

According to research studies, MART reduces toxic, biased, and harmful language in LLM outputs by 31-66%. It requires no additional labeled data. The conversational format mimics human red teaming and is very scalable.

Q: Does MART reduce LLM capabilities?

No, MART maintains the original capabilities of the LLM while improving safety. The generator still produces high-quality, human-like text for any prompt. Only inappropriate responses are selectively discouraged.

Q: How is MART different from other LLM safety techniques? 

Many techniques require extra training data, which can be costly and only works sometimes. MART only needs the critic LLM's judgments during the red teaming process. It is also more dynamic than one-time fixes since the generator continuously improves.

Q: Does MART work for any unsafe output?

MART improves quality across many attributes like toxicity, bias, hate, and violence. The critic can also focus on custom issues by explicitly looking for profanity or other heuristics rather than complex, unsafe content.

Q: How many rounds of generate-critique are needed?

Performance continues improving for at least ten rounds in experiments. More rounds likely lead to further gains but with diminishing returns. The process could be automated to run indefinitely as computing resources permit.

Q: Can MART make LLMs perfectly safe?

MART significantly improves safety but cannot guarantee perfection as language is complex. Combining MART with other techniques like human-in-the-loop approaches can provide further safeguards for high-stakes applications.

Q: Is MART ready to deploy in production systems?

MART shows promising results, but more research is needed to integrate it into real-world applications. Testing for subtle failure cases and scaling up infrastructure are the next steps toward production.

Q: What's next for MART?

Researchers are exploring modifications like tailoring critics to different types of unsafe text, combining MART with other safety methods, and adapting the technique for multimodal LLMs. Expanding MART to cover more complex dangerous behaviors is an active development area.
