LLMs can be very creative, when pushed. In order to find a creative solution, like antirez needed, there are several tricks I use:

Increase the temperature of the LLMs.

Ask several LLMs, each several time the same question, with tiny variations. Then collect all answers, and do a second/third round asking each LLM to review all collected answers and improve.

Add random constraints, one constraints per question. For example, to LLM: can you do this with 1 bit per X. Do this in O(n). Do this using linked lists only. Do this with only 1k memory. Do this while splitting the task to 1000 parallel threads, etc.

This usually kicks the LLM out of its confort zone, into creative solutions.
