Claude Sonnet 4.5 performs three times better at browser navigation and computer use than Anthropic's October technology. Beta-tester Canva deployed the model for complex engineering tasks in its codebase and product features. Anthropic paired the release with virtual machines, memory, context management, and multi-agent support tools, enabling developers to build their own AI agents using the same building blocks that power Claude Code.

Seriously, even an artificial moron can cobble together a "clone" of something that exists. It can just not create a good clone.

Results (Score:5, Insightful)
Okay, now show us the results. "like slack or teams" doesnt mean much, you're obfuscating what it is actually capable of. Are we talking a generic chat system, super basic? or IRC level with users/rooms? what about user registration, activation, moderation? Does it do multimedia like slack/teams? Can you audio/video call?
This right now screams of over-hyping its capabilities and the replacement of human developers even tho it can't do a fraction of what humans can.

Re: (Score:3)
I'd rather say its impressive because it only used 11k lines. I suppose Slack-like only means the basic functionality (rooms, private messages, profiles, persistent chats, frontend, backend) but try to keep this below 11k lines. Writing much code is easy, keeping things short is the true virtue.
Re: (Score:2)
11k? Honestly, it is surprising that it is that long. Slacks is just basic server/client chat app. With some well placed calls to load js libraries off google and other cdns, I think you could do it in half that.

I must say I didn't use the original yet, but 11k for a webapp with backend and frontend doesn't sound much. Before misunderstanding, I think of 11k like in "wc -l", i.e. including all blank linkes, comments without any minimization.
I did not use Opus yet, but AI also tends to include a lot of comments. Not quite like "i++ // increment i", but structuring like "// preprocessing step", "// the main algorithm" and so on. I thought them to be too obvious in some cases, but I've read, and that makes sense, that

Keep in mind that non-human generated code may not have copyright. Not open source, which does have a copyright. But no copyright at all.
There's an argument that if it is modified by a human, it can be copyrighted. But that could be line by line.

Meh, most people here probably prefer if they can open their code. I am not Microsoft. I mostly use licenses so others should give back something for my work. The less work it was, the less I demand credit for it. If I had to chance a lot, it has copyright. If I didn't need to do a thing, I am not opposed to sharing it for free. I mean if you can get another Slack clone with a simple prompt, why does it matter if you copy that one or create a new one?

Slack is just a crippled IRC server in the backend, and a crippled IRC GUI as the front end client.
Basically to make a slack clone you get yourself the IRC source code and delete 11,000 lines of code to remove many of its features.

As a company, Oracle is shit. As a product, Oracle is also pretty crappy in a lot of ways, but it's a functionality and performance leader, and no AI-written RDBMS is going to challenge it in any department period.

MIssing the point? (Score:2)
We're missing the point, I think. It's not that the new model can recreate Slack in 11,000 lines and only 30 hours, it's that the new model can simply work on a single task for 30 hours without shitting itself. Whether or not it produced anything of value in the end is irrelevant.

Most human generated code is riddled with security holes and it takes a lot of careful work to even clear out the most basic ones. AI generated code is not different.

If it can actually turn out a genuinely useful program this way, this would be a major step forward.)
