Knowledge benchmarks can't really be improved upon via distillation or RL. It requires those facts be added to the training corpus and for the model to memorize them better. Neither distillation or RL really do that and thus we shouldn't expect improvements on SimpleQA unless some other interventions are being made.
Model intelligence and knowledge aren't necessarily directly related. If we can pack greater intelligence and agency at the cost of it forgetting factoids, that would actually be a good thing. We don't need LLMs to memorize facts, we need them to learn how to interact with the world such that they can find the facts that are necessary and surface them to the user.
If we could distill all of the knowledge out of an LLM and just be left with a very agentic model that only knows facts in it's context, I think some very interesting stuff would happen.
Lot of the things aren't facts that could be stated. No one can just see the dictionary or translation of words and start talking in that language.
There isn't a clear definition of what is knowledge and what is intelligence. Is being able to write in C knowledge? Is knowing undefined behaviour in that knowledge?
My point is that if I made someone "smarter" they wouldn't suddenly know "What day, month, and year was Carrie Underwood’s album “CryPretty” certified Gold by the RIAA?" which is an example of a question in the SimpleQA benchmark.
So (in my opinion) knowledge benchmarks stagnating for small models is not evidence that small model agentic coding performance improvement will stagnate soon. Small models do not struggle with syntax, the barrier is not knowledge. The barrier is long context coherence and problem solving, which I don't see a bottleneck on improvements for small models in the near horizon as we get more and more high quality reasoning traces to train upon.
