dusseldorf The record of artificial intelligence (AI)-based chat programs has so far been scant. the chatbot Tay pulled its developer Microsoft 2016 offline just 24 hours after publication. Galactic Facebook Group Goal It lasted at least three days last November. Language patterns quickly got out of hand with racist or nonsensical statements.

But with ChatGPT from US start-up Open AI, things are different. It has been accessible since November 30. and surprises with texts and dialogues, that could be from humans.

There are still issues here, such as incorrect or incorrect information or template-like responses. But progress is clearly visible. Microsoft is now expanding its collaboration with Open AI and, according to press reports, it will invest around ten billion dollars in the coming years. What makes ChatGPT so much better? Here are the most important questions and answers.

Open AI started as a foundation in San Francisco in 2015. Known tech entrepreneurs like Elon MuskPeter Thiel, Reid Hoffman, and Sam Altman gave a total of $1 billion toward one goal: developing artificial intelligence that “benefits all of humanity,” as the statute says.

Musk left in 2018 for the automaker he runs tesla he even developed an AI. A year later there was a turning point: the foundation ran out of money because computing power and the corresponding specialists are expensive. Nor was it easy to bring experts to the foundation; after all, they call Google o Target high salaries and stock options.

Therefore, a for-profit subsidiary was formed, headed by founder Altman. All employees of the foundation received shares, Microsoft invested a billion dollars and venture capitalists such as Khosla Venture or the foundation of the founder of LinkedIn, Hoffman, joined.

Today, Open AI is one of the most valuable startups in the world, worth $29 billion. USA. The shares are regulated in a complicated way to do justice to the structure of the foundation. According to several American technological media Microsoft 49 percent of the company, the other investors together also reach 49 percent. The Foundation owns the remaining two percent.

What is GPT Chat?

The name stands for “Chat Generative Pre-trained Transformer”, which Open AI released in late November. The chatbot is based on a machine learning model that understands human input and responds naturally. The chatbot can write poems, summarize texts or even program.

ChatGPT uses language models – currently this GPT 3.5 – trained with large amounts of data, the so-called Large Language Models (LLM). For this, 175 billion parameters and 800 gigabytes of storage capacity were used.

The model works on the principle of reinforcement learning. The program independently develops a strategy in several stages, which is controlled by “rewards”. This can be positive or negative feedback, monitored and provided by humans in the early stages. At the highest level, the program is optimized with the so-called “Proximate Policy Optimization” (PPO).

However, the model can only be as good as the data. For example, if there are racist prejudices, the program will also reproduce them. To prevent this, the Open AI developers used a “moderation filter” which has not malfunctioned so far.

What can you do with ChatGPT?

Everyone can use ChatGPT for free after signing up. However, due to the great interest, the website is often brought to its knees. Anyone who enters the program can create texts that read in an eloquent and structured way and that could be from a journalist or writer. You can understand sentences of up to 1500 words.

The chatbot is so good that it would pass the MBA exam at the elite US university Wharton with the grade “two minus”, as Professor Christian Terwiesch recently wrote in a study. The explanations were “excellent”.

ChatGPT can also translate and speaks multiple languages. However, German has problems with punctuation and grammar, and the sentences are sometimes long and complicated.

The potential is still huge. ChatGPT could potentially change daily work in many industries. Microsoft wants to integrate the AI ​​tool into its Bing search engine, which would then work in a whole new way. Users can then perform search queries as if they were humans and receive full answers instead of a list of links.

What are the disadvantages of ChatGPT?

The developers attach great importance to not giving wrong, misleading or harmful answers. However, there are numerous examples where users have managed to do just that. In the “Historical Figures” app, which uses ChatGPT, users can chat with Jesus or the Beatles, but recently also with Adolf Hitler and other dictators.

However, compared to other chatbots, ChatGPT is much better at avoiding stereotypes. What is always missing are the sources, and the program does not provide any probability for its statements.

Basically, caution is always advised: ChatGPT often gives wrong answers with great eloquence and authority. Falls for trick questions, dark themes are particularly a problem. Current questions are also taboo because the program only trained on data up to the end of 2021. The program answers questions like World Cup 2022, but they are speculation.

What other AI software is still available?

There is a whole range of offerings, each with strengths and weaknesses. Dall-E, for example, offers Open AI create images from text descriptions on demand. The program is based on ChatGPT and recently stopped being free: it is said to cost around 40 euros per month.

An alternative is Bloom, which is the only program with 176 billion parameters trained on more data than ChatGPT. Master 46 languages ​​and 13 programming languages. Open source software is freely available and is particularly valuable in rare languages ​​like Swahili. You can summarize or translate text and it was trained with data until July 2022. However, you have to pay for the cloud service at $40 per hour.

Given the hype surrounding ChatGPT, rumors are mounting that Google will soon follow suit. The Internet group has been working on the so-called “Language Model for Dialog Applications” (Lamda) for some time. This is already used in the “AI Test Kitchen” app, which only runs on Android smartphones and is only available to a small extent.
