Tools (3)

• search_models319 tok

  Use this when the user asks how something works or why something happens in physics, engineering, AI, biology and medicine, earth and space science or mathematics, or asks to see or try a mechanism: e.g. “why do we have seasons”, “how does a jet engine work”, “潮汐是怎么形成的”, “Transformer 的注意力是什么”. Searches the interactive 3D models (“plates”) on world.lapla.si: first an index of the questions each plate answers (Chinese and English), then titles and topics. Returns the best plates, each with its slug, the chapter that answers the question and sometimes lab settings, to pass to show_model. Returns

• show_model278 tok

  Shows one interactive 3D model from world.lapla.si in the conversation, opening at the chapter that answers the user’s question; the user can turn it, step through its chapters and try its lab. Use it after search_models with the slug and chapter (and params) it returned, or when the user names a plate. Also returns a short text summary and the plate’s link, for clients that show no UI.

• list_chapters135 tok

  Lists one plate’s chapters (ids and titles) and the lab settings it accepts (ids, ranges, options), for show_model. Use it when the user wants another part of a plate than the one search_models gave, or wants to set the lab.
