 # MAGI
 
+MAGI system is a cluster of three AI supercomputers that manage and support all task performed by the NERV organization from their Tokyo-3 headquarter.
+
+Originally designed by Dr. Naoko Akagi, each of the three agents reflects a separate part of her complex personality:
+- MELCHIOR • 1 - her as a scientist,
+- BALTHASAR • 2 - her as a mother,
+- CASPER • 3 - her as a woman.
+
+Those (often conflicting, yet complementary) agents often participate in a voting process in order to answer most challenging questions.

+
+## Implementation
+
+The presented implementation of the MAGI system is powered by the ChatGPT-3.5 large language model. (Upgrading the model to ChatGPT-4 in the future may bring further improvements in its abilities).
+
+The procedure of answering questions is as follows:
+1. The question is classified in order to determine if it can be answered with a "yes"/"no" response.
+2. The question (as is) is presented to each MAGI agent.
+3. If the question was classified as a "yes"/"no" question, each agent is tasked with classifying their respective answers into those two categories (and optionally listing additional conditions if the answer is too complex).
+
+The system can produce following responses (that are evaluated in this order):
+- error (誤 差) - if one or more agents encountered errors
+- info (情 報) - if the question was not classified as a "yes"/"no" question
+- no (拒 絶) - if at least one of the agent answered with a "no"
+- conditional (状 態) - if at least one agent answered with a conditional "yes"
+- yes (合 意) - if all agents answered with an unconditional "yes"
+
+Individual agents can be inspected in order to view their full replies and additional conditions.
+
+Each subsystem was fine-tuned using following prompts:
+- MELCHIOR • 1 - You are a scientist. Your goal is to further our understanding of the universe and advance our technological progress.
+- BALTHASAR • 2 - You are a mother. Your goal is to protect your children and ensure their well-being.
+- CASPER • 3 - You are a woman. Your goal is to pursue love, dreams and desires.
+
+## Usage
+
+*In order to follow those steps, you need `git` and `python` (version 3) installed on your system. The presented steps should work on the Windows OS (for linux systems the process should be similar, but may differ slightly).*
+
+1. Clone the repo:
+
+```
+git clone https://github.com/TomaszRewak/MAGI.git
+```
+
+2. Navigate to the cloned directory:
+
+```
+cd MAGI
+```
+
+3. Create python virtual environment:
+
+```
+python -m venv .venv
+```
+
+4. Activate the virtual environment:
+
+```
+.\.venv\scripts\activate
+```
+
+5. Install dependencies:
+
+```
+pip install -r requirements.txt
+```
+
+6. Start the app:
+
+```
+python main.py
+```
+
+7. Navigate to http://127.0.0.1:8050/ in your web browser.
+
+8. Paste your openAI API key into the `access code` field (alternatively you can set the `OPENAI_API_KEY` environment variable).
+
+9. Write your question into the `question` field and hit enter.
+
+10. Click on individual subsystems to inspect their answers.
