Blogger claims Codex Desktop's harness architecture is a generation ahead of Claude

Blogger jakevin7 argues OpenAI's Codex Desktop is a generation ahead of Claude Desktop on agent harness: unified app-server runtime across endpoints, top harness benchmark results, async tool calls with non-blocking inference, server-side context compression, mid-turn steering via Responses API, and sliding context windows with searchable history — while calling Claude Code's per-session architecture legacy. Opinions are strong and some claims unverified, but the technical specifics offer a useful window into both harness designs.
