"Result: 100% accuracy on integer arithmetic" - Could someone with low-level LLM expertise comment on that: Is that future-proof, or does it have to be re-asserted with every rebuild of the neural building blocks? Can it be proven to remain correct? I assume there's a low-temperature setting that keeps it from getting too creative. The creative thinking behind this project is truly mind boggling.
