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
