SubSchool uses GPT-5.6 to turn descriptions, books and video libraries into editable courses, and recorded tutoring sessions into follow-up homework. Terra powers everyday generation and grading; teachers can switch to Sol for complex tasks. Grade essays, interviews, photos, and presentations automatically based on grading criteria, keep teachers in control, and let Codex create or update real course content through MCP.
