GHz spiking neuromorphic photonic chip with in-situ training

Appreciating that not everyone tries to optimise for LLMs and we are still doing things like this. If you're looking at HN alone, it sometimes feels like the hype could drown out everything else.

There is massive hype, no doubt about it, but lets also not forget how LLMs have basically solved NLP, are a step change in many dimensions and are disrupting and changing things like software engineering like nothing else before it.

So I hear you, but on the flip side we _should_ be reading a lot about LLMs here, as they have a direct impact on the work that most of us do.

That said, seeing other papers pop up that are not related to transformer based networks is appreciated.

Nice that they can do the processing in the GHz range, but from some pictures in the paper, it seems the system has only 60 'cells', which is rather low compared to the number of cells found in brains of animals that display complex behavior. To me it seems this is an optimization in the wrong dimension.

I suspect practicality is not the goal here, but rather a proof of concept. Perhaps they saw speed as an important technical barrier to cross

It's just a single linear layer and it's not clear to me that the technology is capable of anything more. If I'm reading it correctly it sounds like running the model forward couldn't even use the technology, they had to record the weights and do it the old fashion way.
