The moat is Windsurf’s custom LLM and the ops around it (training pipelines, fine-tuning, infra).

Codeium (Windsurf’s parent) started as a GPU optimization company, so they have deep expertise there. Unlike most agents that might just wrap OpenAI/Claude/etc Windsurf’s own model powers its code edits, not external API calls.

That’s where the defensibility is. better in-house models + efficient infra = stronger long-term moat

I suspect it’s also around handling large code bases, building out a prompt that is maximally useful via more conventional processing before passing to the LLM
