Understanding Autoregressive Large Language Models (LLMs)
Yann LeCun, a leading AI expert, recently claimed that autoregressive LLMs have significant flaws. He argues that as these models generate text, the chance of producing a correct response decreases rapidly, making them unreliable for longer interactions.
Key Insights on LLMs
While I respect LeCun’s insights, I believe he overlooks important aspects of LLM functionality. In this discussion, I will highlight why autoregressive models can be effective and how techniques like Chain-of-Thought (CoT) and Attentive Reasoning Queries (ARQs) enhance their performance.
What is Autoregression?
Autoregression is a method where an LLM generates text one piece at a time. It predicts the next word based on the previous context and continues this process until it completes a response. This allows for generating anything from short answers to full articles.
Do Errors Accumulate?
LeCun’s argument suggests that as LLMs generate longer texts, the likelihood of maintaining coherence drops significantly. However, this view is flawed because the error rate is not constant. LLMs can correct mistakes as they generate text, similar to how a storyteller can fix errors in their narrative.
Self-Correction in LLMs
LLMs possess self-correction abilities that help maintain coherence. Techniques like CoT prompting encourage the model to think through its responses step-by-step, improving accuracy. Additionally, methods like Chain-of-Verification (CoV) and ARQs help reinforce correct outputs and eliminate errors.
Introducing Attentive Reasoning Queries (ARQs)
At Parlant, we have developed ARQs, which enhance the model’s ability to stay on track during long responses. These queries guide the model’s focus on essential instructions, ensuring coherence and accuracy. Our results show that ARQs can achieve nearly 100% consistency in complex tasks.
Why Autoregressive Models Are Valuable
We believe autoregressive LLMs are not doomed. While they face challenges in long-form coherence, they have mechanisms like CoT and ARQs that help mitigate these issues. These models can be highly effective in customer-facing applications, providing reliable and accurate interactions.
