Summary

In this chapter, we’ve delved into the dynamic and complex world of state-of-the-art LLMs. We’ve discussed their remarkable generalization capabilities, making them versatile tools for a wide range of tasks. We also highlighted the crucial aspect of understanding complex contexts, where these models excel by grasping the nuances of language and the intricacies of various subject matters.

Additionally, we explored the paradigm of RLHF and how it is being employed to enhance LMs. RLHF leverages scalar feedback to improve LMs by mimicking human judgments, thereby helping to mitigate some of the common pitfalls encountered in NLP tasks.

We discussed technical requirements for working with these models, emphasizing the need for foundational knowledge in areas such as Transformers, reinforcement learning, and coding skills.

This chapter also touched on some prominent LMs such as GPT-4 and LLaMA, discussing their architecture, methods, and performance. We highlighted...
