What the other poster here said for testing against a reference, but also as an easier to get started with base for my own coding sandbox with coding agents. Took me quite a while to build one on my own that I was semi-happy with but I'd imagine one solid enough to run cowork on safely might have some deeper thinking and review behind it.

Ok I'd seen some sample sandbox scripts for this from anthropic before but not a full reference container. nice, thank you for sharing.

FWIW I think many of us would actually very much love to have an official (or semi official) Claude sandboxing container image base / vm base. I wonder if you all have considered making something like the cowork vm available for that?

I was trying to make no particular call on the actual reason aside from pointing at how obviously not the real story and false the statements made so far are. What a knot you have to tie yourself into to seek out an explanation where OpenAI has not made an ethical compromise to stay in the game here. I can stretch and think of some ways but they are far from the simplest explanation.

Lots of responses below give the likely real reasons most of which are probably true in part, but my opinion is it's the primary reason all who is in and who is out decisions are made by the trump administration - fealty. Skills, value brought, qualifications, etc. none of that matter above passing frequent loyalty tests, appealing to ego, bribes (sorry, i mean donations). Imagine thinking "hey, we'll work towards fully autonomous killbots because our adversaries will get them too but the tech isn't strong enough to allow them loose yet" or "yes you can use our ai for your panopticon surveillance, but just not on our own citizens because that is illegal" are lefty woke stances but here we are. Dario failed the loyalty test, as anyone rational would.

"We do not think Anthropic should be designated as a supply chain risk"

...but we're not willing to reject a contract to back that up, and so our words will not change anything for Anthropic, or help the collective AI model industry (even ourselves) hold a firm line on ethical use of models in the future.

The fact is if one of the top tier foundation models allows for these uses there's no protection against it for any of them - the only way this works if they hold a line together which unfortunately they're just not going to do. I don't just see OpenAI at fault here, Anthropic is clearly ok with other highly questionable use cases if these are their only red lines. We don't think the technology is ready for fully autonomous killbots, but will work on getting it there is not exactly the ethical stand folks are making their position today out to be.

I found this interview with Dario last night to be particularly revealing - it's good they are drawing a line and they're clearly navigating a very difficult and chaotic high pressure relationship (as is everyone dealing with this admin) but he's pretty open to autonomous weapons, and other "lawful" uses whatever they may be https://www.youtube.com/watch?v=MPTNHrq_4LU
