Smiley's Better Brain

Verity JE is required, and the mod expands what that companion remembers and can do. It adds short-term and long-term memory that persists between sessions, expanded world knowledge, and abilities such as acting on the weather and time, teleporting, riding, summoning and striking with lightning. Verity's default personality is cheerful and energetic, but it can grow colder if players mistreat him, and the mod clarifies his behavioral rules.

The text AI defaults to Gemini 3.1 Flash-Lite, which the author recommends for fast replies, strong instruction following and image understanding. An experimental configuration tab lets players switch to Groq's llama-3.3-70b-versatile, which matches Verity JE's own default Groq model. Gemini's thinking level can be set to Fast, Balanced or Smart. Either provider keeps the memory tools, personality rules and text-to-speech integration. A screenshot falls back to Gemini automatically when Groq is selected.

Admin abilities run immediately by default, without a stream of confirmation dialogs. A server can turn off specific ability categories, require operator level 2, and cap ranges or counts through brain-server.toml. Valuable or dangerous blocks that cannot be obtained in survival stay restricted, and players, bosses other than the protected ones, and similar targets are guarded by default. The mod is published for 1.20.1 and 1.21.1 and runs on client and server, so both the server and every player need it.
