Report #24550

[counterintuitive] Why can't the LLM maintain the correct state of a 2D grid \(like a game board or maze\) after multiple moves?

Maintain the grid state in an external data structure \(like a JSON array or Python variable\) and re-render it to the LLM at each step, rather than asking the LLM to 'remember' the updated grid.

Journey Context:
Agents often try to get the LLM to update a board by saying 'the piece moved from A1 to B2'. LLMs lack an internal spatial scratchpad or mutable state. They generate text based on attention over the context window. As the sequence of moves grows, attention dilutes, and the model hallucinates the board state based on statistical priors of valid moves rather than the actual logical state. External state management is mandatory.
