1.5.5 DeepSeek works again on its new unified model

DeepSeek merged its Instant, Expert and Vision models into a single model and removed the model picker from the chat box. That broke ZeroScript on DeepSeek. This release fixes it.

Fixed

• DeepSeek: the agent starts again. ZeroScript used to wait for one of the model tabs to be selected, so "Start Roblox agent" stopped with "DeepSeek mode not ready". It now recognises the new chat box, switches Search off as before, keeps DeepThink on, and starts.
• DeepSeek: screenshots work on every chat. Images used to need the Vision tab, which no longer exists. The unified model sees your Studio captures, one at a time or several in a row. Older conversations still marked Instant or Expert stay text-only.
