No, you underestimate how huge the malware problem right now. People try publish fake download landing pages for shell scripts or even Claude code on https://playcode.io every day. They pay for google ads $$$ to be one the top 1 position. How Google ads allow this? They can’t verify every shell script.

No I am not joking. Every time you install something, there is a risk you clicked a wrong page with the absolute same design.

He's not talking about malware awareness. He's talking about a bug i've seen too which requires Claude justifying for *every* tool call to add extra malware-awareness turns. Like every file read of the repo we've been working on

Also increasing numbers of attacks against Anna's Archive with fake cloned front end web GUIs leading to malware scripts.

Opus 4.6 is the main model on https://playcode.io.

Not a secret, the model is the best on the world. Yet it is crazy expensive and this 35% is huge for us. $10,000 becomes $13,500. Don’t forget, anthropic tokenizer also shows way more than other providers.

We have experimented a lot with GLM 5.1. It is kinda close, but with downsides: no images, max 100K adequate context size and poor text writing. However, a great designer. So there is no replacement. We pray.

How much human developer can you buy for that $13.5k?

They’ve got us by the balls and they know it.

Gemini is strong and cheap, it's 90% of 4.6 at 20% of the tokens.

When you find a gold, why tell everyone where it is? Silent happiness keeps the benefits:)

Ever heard of economies of scale?

Or Anthropic. Monopolies have different rules.

Tell me about Vercel :)

Hey, congrats! What city do you live in?

I am creating ai website builder https://playcode.io/ai-website-builder, the full stack part.

I have been working on it for 10 years already.

Yesterday I faced 5h window limit for the first time. I was surprised. Max 20x plan. Usually I work 12-15 hours per day 7 days a week with no limits. But yesterday it was under 3 hours… what a pity.

Well, 70% of my commits are “123”.

Congrats guys! Would share some technical details, I bet you have great stories to tell. Let’s, what is forking? You completely copy disk, make ram snapshot and run it? If CoW, but ram? You mentioned 8GB ram vms. Sounds like impossible to copy 8Gb under 500ms, also disk?

So fork time is actually O(1) with VM size, its 500ms even for 64gb + disk. We're using some pretty weird COW techniques to pull it off.

O(1) What! What might bring it down to say 10's of ms? Looks like its some kind of optimizable wall that its 500 for everything.

Like with 10ms then online replication/backup — analogus to litestream for sqlite — but for in memory processes becomes feasible, no?

We're actually median under 500ms — ~320ms median — I just didn't want to piss of hacker news with over estimatation.

We have another set of optimizations that we believe can take us to ~200ms in the next few months but beyond that we're pretty much completely stuck.

Realistically other sandboxes will be able to get there before us because we've chosen to support so much of Linux/if you don't run an operating system or don't support custom snapshots that is much easier.

Insane. Does it possible to fork to another bare metal machine? Maybe multi region as fly io. If not, I bet you have huge disk sizes on your machines to store all the snapshots (you said, you store them and bill only for disk space).

So forking across multiple nodes in that speed is not possible — we run extremely beefy nodes in order to avoid moving VMs across nodes as much as possible.

We are researching systems of hot moving VMs across VMs but it would have very different performance characteristics.

Yeah, I see. Is it possible to get a corrupted state? Let’s say we had realtime database actively writing at that moment?

It is impossible.

Our tech is not decades old so there is a chance we've missed something but our layer management is atomic so I'd be shocked if you'd be able to corrupt state across forks/snapshots.

Also modal.com, I saw a few more as well.
