Anthropic is building moat around theirs models with claude code, Agent SDK, containers, programmatic tool use, tool search, skills and more. Once you fully integrate you will not switch. Also being capital intensive is a form of moat.

I think we will end up with market similar to cloud computing. Few big players with great margins creating cartel.

I thought that, too, but lately I've been using OpenCode with Claude Opus, rather than Claude Code, and have been loving it.

OpenCode has LSPs out of the box (coming to Claude Code, but not there yet), has a more extensive UI (e.g. sidebar showing pending todos), allows me to switch models mid-chat, has a desktop app (Electron-type wrapper, sure, but nevertheless, desktop; and it syncs with the TUI/web versions so you can use both at the same time), and so on.

So far I like it better, so for me that moat isn't that. The technical moat is still the superiority of the model, and others are bound to catch up there. Gemini 3 Preview is already doing better at some tasks (but frequently goes insane, sadly).

I think this is something the other big players could replicate rapidly, even simulating the exact UI, interactions, importing/exporting existing items, etc. that people are used to with claude products. I don't think this is that big of a moat in the long run. Other big players just seem to be carving up the landscape and see where they can can fit in for now, but once resource rich eyes focus on them, Anthropic's "moat" will disappear.

A GPT wrapper isn't a moat.

All those features are basically prompts in various formats, not much of a moat.
