 Gemini is a family of powerful AI models designed to be multimodal, meaning they can understand and generate various types of information, including text, images, audio, video, and code.¹ This makes Gemini incredibly versatile.

To understand the core information about Gemini, consider these key aspects:

1. What it is (The Models & The Chatbot):

• Gemini (the family of AI models): This is the underlying technology. Think of it like the engine. These models are used across Google's products and are also available for developers to integrate into their own applications. 
• Google Gemini (the chatbot): This is the user-facing application that many people interact with. It was formerly known as Bard. This is where you can directly chat with Gemini, ask questions, generate text, brainstorm ideas, and more. 
• Other Gemini-powered products: Gemini is also integrated into many other Google services, such as:
  • Google Workspace: For features like summarizing emails in Gmail, drafting documents in Docs, generating charts in Sheets, and taking notes in Meet. 
  • Google Search: Powering features like AI Overviews and an experimental AI Mode. 
  • Android: Gradually replacing Google Assistant on Android phones and smart devices. 
  • Google Cloud: Offering AI assistance for software development, cloud management, security, and data analytics. 

2. Core Capabilities:

• Multimodality: As mentioned, this is a defining feature. Gemini can process and generate content across different data types, allowing for more complex and nuanced interactions. 
• Text Generation and Content Creation: It can write various forms of creative content, from poems and scripts to emails, blog posts, and marketing copy. 
• Machine Translation and Language Understanding: Gemini can seamlessly translate languages and understand complex grammar, facilitating global communication. 
• Question Answering and Information Retrieval: It can answer even challenging and open-ended questions by drawing on its vast knowledge base and retrieving relevant information. 
• Code Generation and Creative Coding: Gemini is proficient at generating code, offering suggestions, and even helping with debugging. 
• Research and Brainstorming: It can act as a thought partner, helping you explore ideas, summarize documents, and generate new concepts. 
• Image Generation: Gemini can create images from text descriptions. 
• Audio Features: It can generate full audio versions of documents or podcast-style overviews. 

3. How it Works (at a high level):

• Gemini models are pre-trained on massive datasets from publicly available sources. This training allows them to learn patterns, relationships, and knowledge from a vast amount of information. 
• Google applies quality filters to these datasets to enhance the model's performance and reduce biases. 
• When you interact with Gemini, it uses these trained models to understand your prompt (whether it's text, an image, or audio) and generate a relevant and helpful response.

When you ask Perplexity a question, it uses advanced AI to search the internet in real time, gathering insights from top-tier sources. It then distills this information into a clear, concise summary, delivering exactly what you need in an easy-to-understand, conversational tone.

How it works

Perplexity goes beyond simple keyword searches. It uses cutting-edge language models like GPT-4.1 and Claude 4.0 Sonnet to understand the context and nuances of your query. Here’s a breakdown of the process:

Understanding your question

Perplexity leverages sophisticated AI to interpret your question, ensuring it knows exactly what you’re asking.

Searching the web

It scours the internet, gathering information from authoritative sources like articles, websites, and journals. Looking for live updates of a soccer game? Perplexity can do that.
Summarizing information

Perplexity compiles the most relevant insights into a coherent, easy-to-understand answer.

Citing sources

Each answer includes numbered footnotes linking to the original sources, allowing you to easily verify the information or explore further.

Ways to search

1. Pro Search: Pro Search is an advanced AI-powered Search which provides comprehensive, in-depth answers to any query. It goes beyond standard search capabilities by conducting thorough research across multiple sources and delivering detailed, well-organized responses.
With Pro Search you can select which AI model you want applied to your answer: Best (our default option, selecting the most suitable model for your question), OpenAI's GPT 4.1, Anthropic's Sonnet 3.7 and many more

2. Research (formerly Deep Research): Perplexity's most sophisticated research, it employs an advanced framework called test time compute (TTC) expansion that mimics human cognitive processes through iterative analysis cycles.

Research performs dozens of searches automatically, reads hundreds of sources, reasons through material autonomously, and delivers comprehensive reports in just 2-4 minutes.
Free users can enjoy up to 3 Pro Searches per day, while subscribers have access to 300+ Searches daily.

Features

Conversational dialogue

Perplexity responds in a conversational manner. It’s like chatting with an expert who truly understands your questions.

Source transparency

Every answer includes footnotes linking to the original sources. This transparency allows you to easily verify the information or explore further.

Contextual memory

You can ask follow-up questions, and Perplexity will remember the context of your previous queries, ensuring a seamless, flowing conversation.

Example

For instance, if you ask, “What are the health benefits of yoga?”

Perplexity will:
Scan health and fitness websites, medical journals, and yoga blogs
Compile key facts into a helpful overview
Provide a clear, concise answer with citations

Emby Connect is a free optional service that allows a person to use one set of username/password credentials when accessing Emby's Forums and Community as well as any Emby Server's setup for you to login using Emby Connect.

The user no longer needs to remember the URL or IP/port of each Emby Server, not do they have to remember different login names and passwords as set on the different Emby Servers.

Example: you have 2 brothers and 3 cousins running Emby Servers. You have been given access to each server by your family members running the servers. You might have different usernames on each system, IE "bob", "sbob", "bobs", "cousin-bob", "lil-bro", etc. With Emby Connect you no longer need to remember the login credentials or addresses of each server as you can login via Emby Connect with a central username/password. 

Guide for Administrators

You can optionally use Emby Connect for any user that requests it. Have them give you their Emby Connect username which you add to their account on your system and your job is done.  Your Emby Server needs to be setup and ttested to allow Internet access to your server.  If this hasn't been done follow the KB article to get remote access working before using Emby Connect  Remote Setup

Once you have remote access working you can create an account on your system for any users. By default, they will log directly into your server using the username and password you created during their account creation. If a user gives you their Emby Connect username, you simply edit their account on your server filling in the second option shown below.

The user can now login directly with the local credentials on the server or can login via Emby Connect.
From the Server Admin Console click on USERS menu.
