Why Your AI Gets Dumber the Longer You Talk to It

You're not imagining it. Research tested 18 frontier models and every single one degrades as the conversation gets longer. Here's the science behind it.

The 'Lost in the Middle' Problem: Why Your AI Ignores Information in the Center of Long Prompts

Research proved that LLMs attend strongly to the beginning and end of context but poorly to the middle. This is a mathematical property, not a bug.

Why Vector Search and GraphRAG Both End in the Same Context Rot

Vector search and GraphRAG look like opposites, but they share the same final move. Parse the code, retrieve some of it, rerank it, and stuff it into the context window. That last step is where both of them rot, because a model that is handed a pile of chunks degrades the same way no matter how the pile was chosen. Here is why the retrieval layer is not the cure for context rot, and what is.
