But it can't actually deduce, can it? If 136891438 * 1294538 isn't in the training data, it won't be able to give you a valid answer using the model itself. There's no process. It has to offload that task to a tool, which will then calculate and return.
Further, any offloading needs to be manually defined at some point. You could maybe give it a way to define its own tools, but even then they would still be defined by what has come before.
Something which I haven't been able to fully parse that perhaps someone has better insight into: aren't transformers inherently only capable of inductive reasoning? In order to actually progress to AGI, which is being promised at least as an eventuality, don't models have to be capable of deduction? Wouldn't that mean fundamentally changing the pipeline in some way? And no, tools are not deduction. They are useful patches for the lack of deduction.
Models need to move beyond the domain of parsing existing information into existing ideas.
