How does one run Claude Code without network access?
The docker container didn’t have network access. Claude didn’t have permission to execute anything other than the run.sh bash script, which would orchestrate the docker run
in both cases you'd limit it so CC can only talk to the required Anthropic APIs.
So not zero access, but as close to it as you can get.
I started looking at Kaggle again and autoresearch seems to converge to many of the solution vibes there.
Wild ensembles, squeezing a bit of loss out. More engineering than research IMO
If you're resource unconstrained then BO should ofc do very well though.
Good Bayesian exploration is much, much better than grid search, and does indeed learn to avoid low value regions of the parameter space. If we're talking about five minute experiments (as in the blog post), Bayesian optimization should chew through the task no problem.
I wrote up some more notes on that here: https://simonwillison.net/2026/Mar/13/liquid/
It’s certainly cool, but the optimizations are so basic that I’d expect a performance engineer to find these within a day or two with some flame graphs and profiling.
So cheaper than a performance engineer for a day or two... but the Shopify CEO's own time is likely a whole lot more expensive than a regular engineer!
What about more distant software projects? Give it the CPython source code and say you want it to be faster.
