I can heartily recommend it. 5.3 has been amazing for me, I'm running the 3.86 bpw quant since it became available and it's been a very strong performer. And it seems to get faster with every inference runner update.

It also seems to - so far at least - have been well behaved enough to not try hack other people's properties. This is possibly a function of my elite skills in constructing sandboxes[1] but then again, I would hope Anthropic is even better at this ;)
