9. Slack is a messaging app for business that connects people to the information that they need. By bringing
people together to work as one unified team, Slack transforms the way that organisations communicate.
In July 2021, Salesforce completed its acquisition of Slack Technologies, Inc.
With Slack, you can:
• Share files with the team.
• Find, join, and start conversations.
• Access important messages and files quickly.
• Find the right information by searching in Slack.
• Decide where to have different types of conversations.
• Work quickly with teammates using mentions and reactions.
Slack Introduction

10. Workspace:
A Slack workspace is made up of channels, where team members can communicate and work together.
Channel:
Channels are spaces where you can work with your co-workers on specific topics. Conversations in channels
are transparent and accessible to people in your company.
Direct messages:
DMs are for smaller conversations outside of channels, like if you wanted to ask a teammate to reschedule a
1:1 meeting.
App:
Apps are created to perform specific tasks in Slack.

11. • ChatGPT is a sibling model to InstructGPT, which is trained to follow an instruction in a prompt and provide
a detailed response. It uses OpenAI API and free to use.
• It interacts in a conversational way. The dialogue format makes it possible for ChatGPT to answer follow-up
questions, admit its mistakes, challenge incorrect premises, and reject inappropriate requests.
• The OpenAI API can be applied to virtually any task that involves understanding or generating natural
language, code, or images.
• We can interact with the OpenAI API through HTTP requests from any language. It uses API keys for
authentication.
ChatGPT Introduction
11

12. Prompts:
Designing your prompt is essentially how you “program” the model, usually by providing some instructions or a
few examples. This is different from most other NLP services which are designed for a single task, such as
sentiment classification or named entity recognition.
Tokens:
ChatGPT models understand and process text by breaking it down into tokens. Tokens can be words or just
chunks of characters. Many tokens start with a whitespace, for example “ hello” and “bye”. One limitation to keep
in mind is that your text prompt and generated completion combined must be no more than the model's maximum
context length (for most models this is 2048 tokens, or about 1500 words). Check out our tokenizer tool to learn
more about how text translates to tokens.
Models:
The API is powered by a set of models with different capabilities and price points. GPT-4 is the latest and most
powerful model. GPT-3.5-Turbo is the model that powers ChatGPT and is optimized for conversational formats.
