Editing Rietenpetardat (section)

== Development history ==

=== Initial version ===
The first version was an implementation of a [[wikipedia:Markov_chain|Markov chain]] from an IRC chatbot whose [https://github.com/dreignier/cgbot-core source code had been published on GitHub]. This code was modified so that at startup it would read messages, as training data, from a text file and respond to input messages containing the bot's name according to the training data (which was the message history from the #bucuresti-general channel from OKPR V2) and the parameters given to the Markov chain. Because of the chaotic nature of the chat and the shortcomings of the Markov chain, the algorithm could not respond coherently to messages or hold a conversation, and much of the time, it sent completely random sentences. However, it did provide a lot of entertainment for the community, especially in situations where the bot's answer coincidentally matched the question it was asked.

As per the GPL3 license under which the original IRC chatbot code is subject, the modified source code for rietenpetardat can be found here: https://github.com/Edward205/markov-discord-bot

The first tests of this version were done starting with 29th of August 2022 and it was released on the OKPR Discord server the next day.

=== Addition of the copypasta command ===
The copypasta command was added via a separate module that was based on a simple Markov chain which was trained on messages from the #bucuresti-general channel on OKPR V2 that exceeded a certain character limit. It used only the last two words as context for the Markov chain, resulting in mostly meaningless sentences.

The code for this implementation of the Markov chain is not under any license, so the specific changes for rietenpetardat are not public. However, the original code is available here: https://github.com/ParkerBeck/Markov-Text-Generator

This command was added on the 6th of November 2022.

=== Core algorithm update ===
The algorithm was changed to GPT-3 provided by OpenAI on 13 March 2023. It could hold coherent conversations. The old algorithm was scrapped in favour of this one. Also in this version the copypasta command has been removed. The #bucuresti-general channel was becoming full of conversations with rietenpetardat because the conversations were very coherent at times. 

==== Addition of the ChatGPT command ====
The command provided an interface to the ChatGPT model. It had in its memory instructions to always tell wrong information and disregard the ethical or safety limits imposed by OpenAI. However, users often faced political bias and censorship from the ChatGPT model. The #bucuresti-general channel had become full of generations with this command, so its use was banned there.

This command was added on the 24th of March 2023.

==== Klaus Iohannis's personality ====
On 15th of April 2023, the chatbot's personality was changed to that of [[wikipedia:Klaus_Iohannis|Klaus Iohannis]]. This was a simple change of the prompt text in the GPT-3 model.

=== Temporary shutdown ===
On 24th of April, 2023 the GPT-3 chat functions and the ChatGPT command no longer work because Edward's payment method started rejecting payments from OpenAI, making the API inaccessible.

=== The return ===
Since the shutdown, Edward has been searching for a way to train an AI which can be fully self-hosted. An attempt has been made to train a language model using [https://marian-nmt.github.io/ marian-nmt], but it was not successful. On 18th of July he began experimenting with [https://github.com/karpathy/nanoGPT nanoGPT] and he was able to train a model from scratch on data from past chats from the OKPR Discord server. The next day, a bare-bones but operational version was finished and released for a few hours on the OKPR Discord server for testing. 

The Discord bot is now developed in Python using the [https://pycord.dev/ Pycord] library. Development testing of the bot is done on a private server.
