2. ChatGPT (Chat Generative Pre-Trained Transformer) is a large language model-
based chatbot developed by OpenAI and launched on November 30, 2022,
notable for enabling users to refine and steer a conversation towards a desired
length, format, style, level of detail, and language used. Successive prompts and
replies, known as prompt engineering, are taken into account at each stage of the
conversation as a context.
ChatGPT is built upon GPT-3.5 and GPT-4, from OpenAI's proprietary series of
foundational GPT models, fine-tuned for conversational applications using a
combination of supervised and reinforcement learning techniques. ChatGPT was
released as a freely available research preview, but due to its popularity, OpenAI
now operates the service on a freemium model. It allows users on its free tier to
access the GPT-3.5 based version, while the more advanced GPT-4 based version,
as well as priority access to newer features, are provided to paid subscribers
under the commercial name "ChatGPT Plus".

4. Although the core function of a chatbot is to mimic a human conversationalist,
ChatGPT is versatile. Among countless examples, it can write and debug computer
programs, compose music, teleplays, fairy tales and student essays, answer test
questions (sometimes, depending on the test, at a level above the average human
test-taker), generate business ideas, write poetry and song lyrics, translate and
summarize text,emulate a Linux system, simulate entire chat rooms, play games
like tic-tac-toe, or simulate an ATM.

6. OpenAI acknowledges that ChatGPT "sometimes writes plausible-sounding but
incorrect or nonsensical answers". This behavior is common for large language
models, and is called "hallucination". The reward model of ChatGPT, designed
around human oversight, can be over-optimized and thus hinder performance, in
an example of an optimization pathology known as Goodhart's law.
ChatGPT has limited knowledge of events that have occurred after September
2021.
In training ChatGPT, human reviewers preferred longer answers, regardless of
actual comprehension or factual content. Training data also suffers from
algorithmic bias, which may be revealed when ChatGPT responds to prompts
including descriptors of people. In one instance, ChatGPT generated a rap
indicating that women and scientists of color were inferior to white male
scientists.

8. ChatGPT can and will replace certain job roles but the effects will
be far from catastrophic. The key is to understand how to operate
the tool and its capabilities and evolve within our roles.
Organizations are profit-driven and will look to optimize their
profits.
