Yes. Teachers and school admins choose which models students can use in chat, and which one is the default, from a roster spanning OpenAI, Anthropic, and Google: GPT-6 Luna, GPT-6 Sol, GPT-6 Astra, GPT-OSS 120B, Claude Sonnet 5, Claude Opus 5.5, Gemini 3.8 Flash, Gemini 3.1 Pro, and Gemini 3.5 Flash Lite. Live voice calls of up to 10 minutes run on Gemini 3.8 Live, and page-by-page transcription of scans, including historical handwriting, uses Gemini 3.1 Pro. Every figure names the exact model it is using before the first message, on a short “How to use AI responsibly” screen that also shows how many sources it draws on and who created it.
