The Future of On-Device Agentic AI
Localai-Aura is an open-source, self developable agentic framework designed to bring powerful, intelligent AI directly into the user's environment, unlocking a new era of private, cost-effective, and truly self contained local LLM deployment. We are moving beyond cloud dependence to give every user ownership over their cognitive tools.
A weekend project Localai-Aura is designed to be the foundational layer for anyone to create a truly local AI assistant, prioritizing privacy and self-sufficiency over cloud convenience. Developed by RayznGames durong his free time in weekends as an early testing ground for on-device agentic AI deployment.
The mission is to make the power of advanced AI accessible locally to everyone, ensuring that the processing and interaction happen safely and privately on your own device. By deploying LLM's locally, we eliminate privacy concerns. reliance on external APIs, token usage, and server costs, realizing the dream of a truly personal and everlasting "word predictor" for your thoughts. That you steer, Control, and develop. Localai-Aura is the beginning of an end, the future of AI is local.
-
Fully Local No internet connection rquired, Aside when dowloading required imported packages, No API key, no Rate Limits, no more dependabot.
-
Powered by Gemma 4-e2b AuraAI harness uses the underlying GGUIF of gemma 4 e2b, that has been created by Google's Deepmind division, and it's an extremely powerfull and cheap local model for a wide variety of tasks.
-
Single-Query Reasoning: The system excels at answering direct questions and performing logical pattern matching across a wide spectrum of general knowledge topics.
-
Task Execution: It can gracefully handle and execute straightforward coding tasks, providing functional code solutions based on context. (Examples below)
-
Automatic Script Storage The harness detects and saves codeblocks generated on the output of the LLM, extracts the contents of each codeblock and stores them after naming them as a script file in a Scripts folder, near the conversation file.
-
Deep Thinking By Default The model understands how to manage the thinking process by ensuring it pattern matches correctly the intent behind the user's input and the complexity behind the query. Taking way longer thinking routes for complex coding tasks. While keeping sharp quick anwsers for simple questions.
-
Text & Voice Output: Aura supports multimodal input and output, generating coherent text responses and synthesized voice output for audio interaction.
-
Role Adaptability: The agent’s behavior can be modified through roles, it comes with an Aura Coding Role and and Aura General Role by default, (Both roles perform quite well at codeing tasks.) while allowing users to create their own roles, and fine-tune a unique persona and operational style for specific niche tasks.
-
Context Handling: Context is currently managed by feeding conversation inputs and outputs directly into conversation files, establishing a foundational per conversation memory system for keeping a reasonable interaction history. Able to handle up to

Want to change something? If you want to self developr an egent you can, if you want to change a behaviour of the harness, you can, if you want to try a different model, you can, if you want to change anything, just get you hands dirty and intervene. Noone here is going to stop you.
- Gemma4-e2b Uses the lightweight ~4Gb gemma 4 - E2B Model for fast on device deployment
- Llama_CPP Instead of transformers as the inference engine.
- PiperVoice Uses piper voice with a text sanitizaion phase for speaking the llm generated output fluently.
- Basic UI A basic TK Event loop for handling the window and 2 buttons for the LLm processing, and for stopping voice output
- Threaded Voice The voice output is handled in a separate thread and controlled with a stop flag.
- GPU Fully offloads all of the Model weights to GPU if possible. Uses CPU for the rest of the weights when GPU limit is reached.
- Clone or download this repository
- Create and activate a virtual environment inside the cloned folder
python -m venv .venv
source .venv/bin/activate- Install requirements
pip install requirements.txt`- Run the
AI_Assistant.pyscript
The pip command cannot create, GPU support by default, for that you need to compile with CUDA the Llama_ccp python C++ code for GPU compatiboility.
We need to ensure your system has the CUDA Toolkit (the compiler) installed and then force a clean compilation of the library using the CUDA compiler.
Start a System terminal and run:
nvcc --versionIf it shows a version Proceed to Step 2
- If it outputs "command not found" It means you need to install the cuda toolkit
sudo apt update sudo apt install nvidia-cuda-toolkit
(If you already have in your systemn cmake and build-essential skip to Step 3)
To compile C++ code during a pip install, you need cmake and build-essential. Run this:
sudo apt update
sudo apt install build-essential cmake -yCreate if not already created and activate your virtual environmnet from the project folder in a terminal.
source .venv/bin/activate- Install requirements (This
requirementsGPUcommand explicitly excludes Llamma_cpp since you will install it in the final step compiled for cuda)
pip install requirementsGPU.txtFInaly install Llama_cpp compiled for cuda, run the command. (This keeps llama_cpp within the .venv project scrope.)
CMAKE_ARGS="-DGGML_CUDA=on" pip install llama-cpp-python --upgrade --force-reinstall --no-cache-dirNo cahce dir is used to avoid fetching an already existing CPU version in cache. So we redownload and compile with cuda and reinstall the package in case it was already installed with CPU suport.
Run the next script cuda_test.py to see if llama_cpp has cuda support
from llama_cpp import Llama
import llama_cpp
print(f"Is CUDA available in llama-cpp? {'Yes' if llama_cpp.llama_supports_gpu_offload() else 'No'}")The output if everything went well should be something similar to:
python3 cuda_test.py
ggml_cuda_init: found 1 CUDA devices (Total VRAM: 7813 MiB):
Device 0: NVIDIA GeForce RTX 4060, compute capability 8.9, VMM: yes, VRAM: 7813 MiB
Is CUDA available in llama-cpp? YesThe harnes that you have acces here, has been initially developed as a voice assistant, and evolved into this wild wested frankenstein of APP in a single file. I know it can be confusing but it has everything you need and the foundational layer for creating a conversatiuon switcher and memory system. Lets explora what you can do with this harness.
When we recieve the generated LLM output we clean the thinking Leak and send the clean text for sanitization in order for piper to read it out loud. With the voice of a female. You can always stop the speak if too cumbersome for you.
When the LLM generates an output with scripts we proceed and pattern match any possible codeblocks, extract them from the output, and store them in a file, while keeping the cleaned text without the codeblocks for later reading.
The framework for Microphone voice input translated as text with VOSK, is in place and should only be piped to the input of the llm prompt, and to execute the process text function once the text has been fully transcribed.
The system is practically ready to handle agentic loops, you can code your own loops, based on the work you want to perform with the model.
The TK GUI will not handle the entire conversation context, the model will continue to work, but the stupid scrolling canvas solution won't suffice for long contextual conversations, and it reaches a point where it cannot display any further labels down the scrollbar. However if you push the model will work, however TK may give errors!
I will discuss key findings and unique insights about how they work and the subtle differences and nuances that make them perform (better/worse) at the inference level.
This is about how you with LocalAI Aura can have a similar level of word Generation Quality Locally in your average gamer computer!
The subtle differences in how LMs manage randomness and predictions directly impact the quality and style of the generated output. These nuances determine whether a model performs "better" or "worse" in specific contexts:
As you all know temperature controls the randomness added to the model If radomness is 0 the language model performs as an instruction follower, sort of like a calculator, if i start writing the first page of a book and the model had the book in the training examples data, it will continue it, no matter what. (Unless the examples trained it to avoid that)
I specifically use this method Tempeature = 0.1 with the <|think|> token to ensure full instruction following, after that, i have to fine tune the fine grained details needed in the format / strcture / system prompt/ input for that singlle generation process. WIch is a hit and miss. Let me explain.
When i made the convesational Aura and its generation was fantastic under my own tests. because it passed all of them with excellence. Something that prior tests in other models never succedeed gracefully. I was confident i cracked the code for making LLM's do what i want. (I thoght i knew the structure and the format)
It turns out that its not all about the format of your prompt, what guidelines you give, or what is the user query, not even about your dicts.
-
Failure to start turn The model does not understant clearly when its its
<start_of_turn>modelor<bos>and it returns an empty response even if thinking was active. -
Bad Thinking Token Seems like the thinking token can only be placed in concrete positions when pasing the context for inference, if not it wont generate good results. or will cut them mid generation stream.
-
Unaware of turn The model does not understant clearly who is in the conversation even if <|think|> is enabled: | Model | Assistant | System | User |
-
Sparse System Instructions The System Prompt is sparse and Vague therefore not activating any of the right weights containing the correct training data for the right outcome, Creating what i consider weight noise.
-
Wrong Context Formatting or ppositioning If the model does not have the right positioning or knowledge of the context window, it wll fail, this not only depends of the ammount of substance in the context but the correct arrangement for the model to undestand that the given piece of information is context for the user query. And the when and the how that context is presented to the language model inside the final prompt heavily infulences it's final generation outcome (It as well Depends heavily in the formatting used during training)
-
Contextual Weighting: The way the model assigns weights to different parts of the input context directly influences the relevance and emphasis of generated statements, leading to superior contextual coherence. when properly contextualized. Unless the right weights are activated trough a thorrowly crafted role file. Top k and top P wont have meningfull results since they will be sampling high values on low interest weights (Roles activate weights and reduce noise the more nuanced they are)
-
Low Cxt Limit Models are loaded with a limit of context, its a hard boundary to avoid using more memory than available/processabble, the higher the Cxt token count, the longer contexts they will handle and longer "thinking" outputs and answers are allowed to happen. (However extremely big contexts are really noisy and increase the chance for hallucnation events) (Tested with Gemma 4 E2B Model.)
-
Not enough Maximum Token count If the Max token count the model can work on an output is not large enough for a complete answer to be fufilled, truncation shortcuts will diminish the returns when activating the right weights. make sure the MAX token count can fit whatever you're trying to do. and use it to truncate the output if necessary. its a hard boundary for the models, and you can use it to your advantage otherwise. For short flash answers, use a max token output of 512, for long reasoning tasks and documentation use limits at least above 15000
-
Role File Importance: The specific instruction set provided (the "role file") acts as a powerful constraint, shaping the model's behavior towards the desired persona or for a task outcome, which is critical for high-quality targeted generation thanks to the activation of the corrct weights for the outcome.
Understanding how model weight activation occurs is essential for optimizing performance in a single task:
-
Weight Allocation: This refers to the dynamic distribution of internal parameters (weights) during the prediction phase. For a local model, this activation must be carefully managed to ensure that random noise does not overwhelm the found patterns in the input, but rather enhances the exploration of valid (vectors) of linguistic structures provided in the context or the role.
-
Optimizing for Task: In a single task, like
coding, successful activation means channeling the model's inherent randomness (stochasticity) into predictions that adhere strictly to the constraints set by the prompt and role file, resulting in high performance in the given task.
Diinishing returns are expected in any other task not related to the main task defines by the role, due to the weight activation phase not waking enough non task related weights.
- Examples are Fundamental Models are trained on vast ammounts of examples, make sure to call the correct examples in your role / context to guide the prediction better. When a model is not performing a task as correctly or is missing the point of the goal, even if the correct weights are activated, and tries to perform the task but fails. It means that the model does not inherently totally know the right pattern or structure to predict, This can be greatly reduced or completely eliminated, if examples of the expected output based on a few inputs are provided (Again correctly formatted is really important), This then can then be fed to the model to internalize trough retraining. Wich will open that space again for extra contextualization.
This is really key to reduce the "thinking" time and increase "thinking" precision, ensures the most tokens used during the inference are targeted to crafting the outcome and not the pattern finding.
When i initially made the first prototype of this, i included the initial system prompt Google provided "You're a helpfull AI Assitant"
I said "Hi". and responded with the classic "I am gemma 4 and i am ready to assist you"
The answer is the generic message of an assistant and there's nothing wrong with that, until you ask it a more nuanced question and i recieve the sorta same response:
"I am gemma 4 and i am ready to assist you creating a script for your project."
No script, no outline, no layout of what to do. Diving deeper into what is going on behind this simple issue reveals a great caveat in this technology. And a deep security issue when deployed at mass scale trough the internet. (You already know about that)
It seems that the inputs you provide matter more than you think for what you're trying to do.
I restructured the prompt format many times, tried the <|think|> token and played with all the parameters, followed the prompt format, laid out in HuggingFace and even formatted the dicts directky targetted to Gemma. and nothing seemed to make it consistent And remember consistency is key when working with these things.
I tried to make it generate a filename based on the codeBlock it just outputted, so i can then save the script with that name, its the same model, same prompt format, but different instruction. If it has been able to generate such wonderfull output and scripts it should have no problem looking at the script it wrote, and output its name. Right?
Wrong.
The model outputted Empty responses:,the examples in the system prompt, or moslty another instruction for when a valid filename was not found "Unnamed_File", and sometimes it even bled its thinking process into the filename, and if the name fit the valid name lemgth, it wrote the file. This is a generated filename:
<|channel>thought Thinking Process: 10. **Analyze the Request:** The user is asking for a single filename that represents the provided C# script (which uses using UnityEngine; and implements movement based on Rigidbody)
This clearly started to paint the story i initialy believed behind all of this.
The system prompt and prompt format that worked flawlessly for a conversational assistant / agent does not work for other sppecific tasks like naming a file even when the instructions and guidelines ask it to do so.
This means that under the surface the prompt format and content makes the weights you get to be activated, these are the ones responsible for the output of this machine. if you dont activate enough of the "correct" ones that you need, your output wil never be the expected one. Lets go back to the calculator analogy.
All the numbers of an operation create an output, if a number in this operation changes, the output changes.`
