GBrain picks the right context for a three-book working memory
garrytan · x · 2026-07-20
Garry Tan says an LLM can effectively keep three book-sized chunks in working memory, and that GBrain helps choose the right three for the current task.
The point is that this becomes especially useful when:
- the context is very large
- the information is personal and task-specific
- selecting the right context matters more than just dumping everything into the prompt
He frames it as a practical unlock for both personal and business use cases.
