The author shares their journey of enhancing AI's understanding of codebases, revealing that existing code generation LLMs operate more like junior developers due to their limited context and lack of comprehension. By developing techniques like Ranked Recursive Summarization (RRS) and Prismatic Ranked Recursive Summarization (PRRS), the author created a tool called Giga AI, which significantly improves AI's ability to analyze and generate code by considering multiple perspectives, ultimately benefiting developers in their workflows.
