[counterintuitive] LLM loses track of specific variable values or state over long multi-step reasoning

Use external state tracking \(writing variables to a JSON file, database, or code environment\) instead of relying on the context window to hold exact state across steps.

Journey Context:
The consensus is that if a state fits within the context window, the model 'remembers' it perfectly. In truth, LLMs are pattern matchers, not state machines. Attention mechanisms apply softmax over all tokens, meaning distant state variables have decaying influence. Over a multi-step process, exact values \(like 'The user's ID is 8492'\) degrade into approximate patterns \('The user's ID is some 4-digit number'\). No prompt can turn a transformer into a Von Neumann machine with perfect random-access memory.
