Are there any interesting/uniq features present in it that are not in the alternatives? My understanding is that its just a client for the powerful llm

Isn't it open source? Or is there an open source front-end and a closed backend?

No

No, it was never open source. You could always reverse engineer the cli app but you didn't have access to the source.

You may have mistaken it with Codex https://github.com/openai/codex

The big loss for Anthropic here is how it reveals their product roadmap via feature flags. A big one is their unreleased "assistant mode" with code name kairos. Just point your agent at this codebase and ask it to find things and you'll find a whole treasure trove of info.

From the directory listing having a cost-tracker.ts, upstreamproxy, coordinator, buddy and a full vim directory, it doesn't look like just an API client to me.

The code looks, at a glance, as bad as you expect.

Is this significant? Copilot on OAI reveals everything meaningful about its functionality if you use a custom model config via the API. All you need to do is inspect the logs to see the prompts they're using. So far no one seems to care about this "loophole". Presumably, because the only thing that matters is for you to consume as many tokens per unit time as possible. The source code of the slot machine is not relevant to the casino manager. He only cares that the customer is using it.

I know HN doesn't like AI comments, but since folks might be reluctant to download + investigate this code, Anthropic's own model says the differentiators are: > the hooks lifecycle API, the multi-tier compaction system, the coordinator/swarm architecture, worktree-based isolation, and the enterprise policy layer.
From my cursory read, the compaction seems to have a lot of effort put into it.

Can you give an example? Looks fairly decent to me
