【推荐1】What Is ChatGPT?

ChatGPT is a large language model chatbot developed by OpenAI based on GPT=3. 5 (Click to learn more). It has a remarkable ability to interact in a conversational dialogue form and provide responses that can appear surprisingly human. Large language models perform the task of predicting the next word in a series of words.

Is ChatGPT Free To Use?

The use of ChatGPT is currently free during the “research preview” time. The chatbot is currently open for users to try out and provide feedback on the responses so that the AI can become better at answering questions and to learn from its mistakes. However, ChatGPT is envisioned as a tool that the public will eventually have to pay to use.

How Can ChatGPT Be Used?

ChatGPT can write code, poems, songs, and even short stories in the style of a specific author. The expertise in following directions elevates ChatGPT from an information source to a tool that can be asked to accomplish a task. This makes it useful for writing an essay on virtually any topic. ChatGPT can function as a tool for generating outlines for articles or even entire novels. It will provide a response for virtually any task that can be answered with written text.

Limitations

●ChatGPT sometimes writes plausible-sounding but incorrect or nonsensical answers. Fixing this issue is challenging, as: (1) during RL training, there’s currently no source of truth; (2) training the model to be more cautious causes it to decline questions that it can answer correctly; and (3) supervised training misleads the model because the ideal answer depends on what the model knows, rather than what the human demonstrator knows.

●ChatGPT is sensitive to tweaks (微调) to the input phrasing or attempting the same prompt multiple times. For example, given one phrasing of a question, the model can claim to not know the answer, but given a slight rephrase (重新措辞), it can answer correctly.

●While we’ve made efforts to make the model refuse inappropriate requests, it will sometimes respond to harmful instructions or exhibit biased behavior. We’re using the Moderation API to warn or block certain types of unsafe content, but we expect it to have some false negatives and positives for now. We’re eager to collect user feedback to aid our ongoing work to improve this system.

【推荐2】Charlotte Grainger explains that it was her primary school teacher who first speculated that she might write a novel. “I thought the height of achievement would be to write a book because it seemed such a challenge and anyway I didn’t know what other teenagers were doing, like being in the Olympics, for example. When I turned 13, I thought I may be as well attempt this now. Recently I told my ex-teacher about it and she was astonished. She told me she’d meant I’d do it when I was 30 or 40. That had never occurred to me — I couldn’t understand why I’d be expected to put something on hold that I had a chance of being good at.”

It’s a winter afternoon, in the offices of Charlette’s publishers. The public relations representative for the book is keeping us company in case Charlotte might need defending. But she needs neither parental nor professional support. She’s her own person: spirited, with an alert face and great intelligence, but also a steadiness that prevents any overconfidence she could be forgiven for feeling.

She has a theory about teenagers and the way they are “betrayed” by the fiction that is specifically aimed at them. There are, she maintains, three types of teenagers depicted in novels. “There’s the outsider who becomes acceptable to society, the naive teenager who knows nothing about the big wide world, and the awkward teenage character who is socially skilled. The overall impression teenagers can get from some writers is teenagers can’t possibly know who they are because they are not experienced enough to know the truth. And when that is being pushed onto them by writers, it can undermine their self-belief. ”

Charlotte has always been a keen reader of famous fantasy writers, some of whom you might suppose she’d be grateful to, but in fact they almost put her off writing entirely. “Books by my favorite fantasy writers explore deep things about psychology and about life. I was asking myself: is this seriously what I have to be doing to write a good book and am I really up to it?” She does, however, praise the influence of a book called “How Not to Write a Novel. “It tells you that if the reader starts to guess what’s going to happen, the suspense has probably gone. ”
