The LLM can set breakpoints, step through execution, inspect variables, and evaluate expressions, effectively acting as a junior developer aiding in the debugging process. The extension aims to streamline debugging by letting the LLM analyze the code and runtime state, suggest potential fixes, and even autonomously navigate the debugging session to identify the root cause of errors. This approach promises a potentially more efficient and insightful debugging experience by leveraging the LLM's code understanding and reasoning capabilities.
Hacker News users generally expressed interest in the LLM debugger extension for VS Code, praising its innovative approach to debugging. Several commenters saw potential for expanding the tool's capabilities, suggesting integration with other debuggers or support for different LLMs beyond GPT. Some questioned the practical long-term applications, wondering if it would be more efficient to simply improve the LLM's code generation capabilities. Others pointed out limitations like the reliance on GPT-4 and the potential for the LLM to hallucinate solutions. Despite these concerns, the overall sentiment was positive, with many eager to see how the project develops and explores the intersection of LLMs and debugging. A few commenters also shared anecdotes of similar debugging approaches they had personally experimented with.

Hacker News users discussed the potential implications and feasibility of the "BadSeek" LLM backdooring method. Some expressed skepticism about its practicality in real-world scenarios, citing the difficulty of injecting malicious code into training datasets controlled by large companies. Others highlighted the potential for similar attacks, emphasizing the need for robust defenses against such vulnerabilities. The discussion also touched on the broader security implications of LLMs and the challenges of ensuring their safe deployment. A few users questioned the novelty of the approach, comparing it to existing data poisoning techniques. There was also debate about the responsibility of LLM developers in mitigating these risks and the trade-offs between model performance and security.
The Hacker News post "Show HN: BadSeek – How to backdoor large language models" generated several comments discussing the presented method of backdooring LLMs and its implications.
Several commenters expressed skepticism about the novelty and practicality of the attack. One commenter argued that the demonstrated "attack" is simply a form of prompt injection, a well-known vulnerability, and not a novel backdoor. They pointed out that the core issue is the model's inability to distinguish between instructions and data, leading to predictable manipulation. Others echoed this sentiment, suggesting that the research doesn't introduce a fundamentally new vulnerability, but rather highlights the existing susceptibility of LLMs to carefully crafted prompts. One user compared it to SQL injection, a long-standing vulnerability in web applications, emphasizing that the underlying problem is the blurring of code and data.
The discussion also touched upon the difficulty of defending against such attacks. One commenter noted the challenge of filtering out malicious prompts without also impacting legitimate uses, especially when the attack leverages seemingly innocuous words and phrases. This difficulty raises concerns about the robustness and security of LLMs in real-world applications.
Some commenters debated the terminology used, questioning whether "backdoor" is the appropriate term. They argued that the manipulation described is more akin to exploiting a known weakness rather than installing a hidden backdoor. This led to a discussion about the definition of a backdoor in the context of machine learning models.
A few commenters pointed out the potential for such attacks to be used in misinformation campaigns, generating seemingly credible but fabricated content. They highlighted the danger of this technique being used to subtly influence public opinion or spread propaganda.
Finally, some comments delved into the technical aspects of the attack, discussing the specific methods used and potential mitigations. One user suggested that training models to differentiate between instructions and data could be a potential solution, although implementing this effectively remains a challenge. Another user pointed out the irony of the authors' attempt to hide the demonstration's true purpose by using a fictional "good" use case around book recommendations, potentially inadvertently highlighting the ethical complexities of such research. This raises questions about responsible disclosure and the potential misuse of such techniques.
