dev here 👋 not yet but definitely interesting in doing it (just annoying to setup)

I used LLRT's Lambda release without the SDK. I tried round-trip latency but couldn't get good measurements, but I'm not an AWS person. I think duration is most important as this is specifically cold starts but happy to follow up.

Thanks! Yes, there are a surprisingly number of use cases and embedded is a big one like any environment where you can't JIT but want better performance then interpreting.

For embedded you can either use Wasm or Porffor's compile to C feature and give that to some proprietary compiler, etc

Yeah afaik that is just AWS overhead

potential outcomes:
- we both waste 5 minutes
- I waste a few hours
- we cry with joy :)

Oh yeah, but I mean it relies on the engine itself having asan etc

Yeah, Fuzzili is very cool but hard to integrate, especially since it is made for being used with coverage and sanitizers which I don't have 😅

I like the idea of using a small model but I think it would heavily limit throughput. It currently runs >1k cases/second and it would probably be much less even with a tiny model running locally 😅
