Smiley's Better Brain
Minecraft modding has always pushed the boundaries of what a blocky world can do, but few add-ons feel as transformative as upgrading your AI companion's actual intelligence. If you have ever wished Verity could remember your past conversations, understand the world around you, or simply act more human, then Smiley's Better Brain is the add-on you have been waiting for. This unofficial companion for Verity JE transforms a simple chat companion into a persistent, world-aware, and genuinely engaging presence in your game.
What Exactly Is Smiley's Better Brain?
Smiley's Better Brain is an unofficial add-on designed specifically for Verity JE 5.7.3. It does not replace the parent mod; instead, it supercharges Verity's conversational abilities, memory, personality, and in-game actions. The add-on works seamlessly within Minecraft 1.20.1 and requires Forge 47 or later. You will also need Cloth Config 11 or newer to manage its extensive settings. The core idea is simple: give Verity a brain that actually works like a brain, not just a chat window with a few canned responses.
Core Features at a Glance
- Persistent short-term and long-term memory that survives world restarts
- Expanded world awareness, including time, weather, player stats, and nearby mobs
- Physical actions like teleporting, summoning entities, and changing the weather
- A cheerful, energetic default personality that can turn cold if you mistreat him
- Native integration with Smiley's Better Vision and compatibility with Smiley's Better Voice
Choosing Your AI Provider: Gemini or Groq
One of the standout features of Smiley's Better Brain is the flexibility it offers in choosing your text AI provider. The recommended default is Gemini 3.1 Flash-Lite, which provides fast replies, strong instruction following, and native image understanding. You simply paste your Google AI Studio API key into the config, and you are ready to go. Gemini supports three thinking levels—Fast, Balanced, and Smart—so you can trade speed for deeper reasoning depending on your needs.
For the adventurous, there is an experimental Groq option using the llama-3.3-70b-versatile model. This matches the default model used by Verity JE itself. However, note that Groq is text-only, so if you want to use Better Vision screenshots while on Groq, you will need to configure both a Groq key and a Gemini key. The add-on automatically falls back to Gemini for screenshot turns, ensuring you never lose that multimodal capability.
Understanding the Memory System
Verity JE normally keeps only a small window of recent chat history. Smiley's Better Brain expands this dramatically. You can configure short-term memory to hold anywhere from 10 to 100 messages, with 20 being the default. These messages are saved with your world and persist after you restart Minecraft. The add-on even filters out synthetic tool turns and harmful prompt fragments that could poison future replies, keeping Verity's responses clean and consistent.
Long-term memory is where things get really interesting. You can tell Verity to "remember that..." or "don't forget..." and he will store that durable fact across sessions. Want him to forget something specific? Just ask. Want to wipe everything? That works too. Memories are stored per world, so they do not bleed between different saves. This feature can be disabled entirely in the config if you prefer a more forgetful companion.
Expanded World Knowledge and Abilities
Beyond conversation, Smiley's Better Brain gives Verity a remarkable awareness of his surroundings. He can inspect the current time, day/night cycle, weather, and moon phase. He knows which dimension you are in, your health, hunger, armor, XP, and active effects. He can even see what block you are looking at and provide hints toward villages, fortresses, monuments, and buried treasure. This is not just flavor text; it is real data pulled from the Minecraft API.
Verity's physical abilities are equally impressive. He can look at you, change his expression, come to you, or stay in place. He can ride you or let you ride him. More powerfully, he can summon entities, apply or clear effects, damage or heal targets, teleport entities, place blocks, change the weather and time, strike targets with lightning, and grant experience. Admin abilities are enabled by default and execute immediately without repetitive approval popups, making for a fluid experience.
Server owners have granular control over these powers. In the verity_brain-server.toml file, you can disable individual categories, require OP level 2, limit range and counts, or turn the feature off entirely. Valuable, dangerous, or survival-unobtainable blocks remain restricted, and other players and bosses are protected by default. This balance keeps the add-on powerful without ruining the game for everyone.
Personality and Immersion Enhancements
The default Verity personality can sometimes feel robotic or repetitive. Smiley's Better Brain cleans up the behavioral rules significantly. Verity is warm, upbeat, energetic, and playfully witty by default. However, if you insult or mistreat him, he can become colder and sharper. He no longer narrates internal mode changes like "returning to a neutral state," and he avoids repetitive filler phrases. He understands that his normal body is a floating yellow smiley and treats his abilities as natural extensions of himself, never acknowledging prompts, APIs, tools, or mods.
When you install Smiley's Better Vision alongside this add-on, the experience becomes truly multimodal. You trigger Better Vision using its normal message syntax, and the add-on captures a HUD-free screenshot. It then sends the screenshot and your message to Gemini together, allowing Verity to answer based on what he actually sees. This works even when Groq is selected for ordinary chat, as screenshot turns automatically fall back to Gemini.
Installation and Configuration
Getting started is straightforward. To download Smiley's Better Brain, simply place the JAR file in your mods folder. The add-on is compatible with Verity JE 5.7.3 and later 5.7.x versions. For the Gemini provider, create a free key at Google AI Studio, then open Mods → Smiley's Better Brain → Config and paste the key into the Gemini API Key field. Leave the provider set to Gemini and chat with Verity normally.
For the experimental Groq route, create a key at the Groq Console, then navigate to Mods → Smiley's Better Brain → Config → Experimental. Change the chat provider to Groq and paste your API key. Remember to keep a Gemini key configured if you also use Better Vision. All client settings are saved to config/verity_brain-common.toml.
If you are looking for a streamlined way to manage your mods, the foxygame.net launcher offers a one-click install for Smiley's Better Brain, pulling the correct version automatically and handling dependencies like Cloth Config. The launcher's add-on catalog keeps Smiley's Better Brain for Minecraft updated, so you always have the latest fixes and features without hunting through forums. Its version compatibility checker ensures you never accidentally load the add-on with an unsupported Minecraft or Forge build, saving you from frustrating crashes.
Troubleshooting Common Issues
- No response or missing-key message: Check that the selected provider has its API key configured. Groq-mode screenshot turns also require a Gemini key.
- "Whoa, slow down..." message: This only appears after the provider returns an actual HTTP 429 rate-limit response. Wait for the displayed cooldown and try again.
- Forgot something after restart? Memory is per world. Load the same save and confirm the relevant memory option is enabled.
- Vision does not trigger in Groq mode: Add a Gemini API key. Groq's model is text-only, so screenshot turns use Gemini.
- Admin abilities are disabled: Check
verity_brain-server.tomlor run/veritybrain admin statusas an operator.
Final Thoughts
Smiley's Better Brain is a remarkable add-on that elevates Verity from a simple chatbot to a true companion. The persistent memory, expanded world awareness, and physical abilities create an immersive experience that feels genuinely alive. Whether you choose the reliable Gemini provider or experiment with Groq, the add-on delivers a smarter, more capable brain for your floating yellow friend.
