Lemonade.gg charges $20 for 100 prompts. ZeroScript Free is an open-source Chrome/Edge extension that connects DeepSeek to Roblox Studio via MCP, with experimental support for other AI models. No API key, no subscription, no prompt limits. You type in DeepSeek, your game changes in Studio in real time. Gemini and ChatGPT are partially supported (unstable for now). The architecture is model-agnostic by design.
