Types of Artificial

Intelligence

Artificial Intelligence (AI) is a branch of computer science

dedicated to creating systems capable of performing

tasks that typically require human intelligence. These tasks

include reasoning, learning, problem-solving, perception, and

decision-making. AI systems process vast datasets to identify

patterns and act on them, often automating complex or

routine tasks

A.I

Public

(Commercial

AI)

Private AI Local AI

Free or Paid Online Service

(Eg. Chatgpt, Deepseek,

Claude, Gemini, Grok)

Installed on Networked

Computers or Servers (Eg.

Neuros Private AI), Customized

to Network Needs

Installed on Powerful Desktop

Computers, Customized to

User’s Needs

Public A.I

1. Input your query (called

Prompts) into the chatbox

2. AI will process the input

information and performs

analysis tasks (thinking)

3. AI will output the solution or

desired results of your

prompts for the task

4. AI output depends on

publicly available

information on the Internet,

require Internet Access to

Work

Public A.I

1. Input your query (called

Prompts) into the chatbox

2. AI will process the input

information and performs

analysis tasks (thinking)

3. AI will output the solution or

desired results of your

prompts for the task

Private A.I

1. Input your query (called Prompts)

into the chatbox of the Ollama

App

2. AI installed on the Server will

process the input information and

performs analysis tasks (thinking)

3. AI will output the solution or

desired results of your prompts

for the task

4. AI will retain all information that

you privately trained it with, with

possibility to update with public

information without leaking

information online.

5. AI can be accessed without

internet access to commercial

servers (offline)

Local A.I

1. Input your query (called

Prompts) into the chatbox of

the Ollama App on User PC

2. AI will process the input

information and performs

analysis tasks (thinking)

3. AI will output the solution or

desired results of your

prompts for the task

4. Method of output is the same

as Private (Network) AI

Advantages/Disadvantages of the Types of A.I

Type Advantages Disadvantages

Public AI

• Free to Use or Low subscription Cost

• No hardware needed (any computer or smartphone

can access the AI over the Internet)

• Fast Output (Commercial Data Centre)

• No need to train the AI

• AI Company can access and sell your private data, and all

your prompts made to the chatbox (password, username,

credit card number, etc)

• Safety issue. Password storage on local PC can be

accessible by hackers

• Require external Internet Access to work

Private AI

• All prompts and AI output is private, cannot be

accessed by AI companies & third parties

• Suitable to process confidential company data and

secret product data and information, access to

company staff only

• Does not require external internet access to work

• Training of A.I is required to suit the company’s

knowledge base and competencies

• Before training the AI model, the output generation is

slower than Public AI

• Expensive (hardware investment in server PC is required)

Local AI

• All prompts and AI output is private, cannot be

accessed by AI companies and other computers on

company network

• Suitable for specialized use (eg. CAD design, movie

production, 3D model generation)

• Does not require external internet access to work

• Training of A.I is required to suit the user’s requirements

• Before training the AI model, the output generation is

slower than Public AI

• Very Expensive (hardware investment in powerful high

end graphics PC is required)

Training AI Models

(Private AI and

Local AI)

• When using Ollama, always select the Medium

Thinking mode to maximize the CPU usage with more

reliable accuracy

• Neuros Private AI uses the following models: (gpt-

oss:20b), (qwen3-vl:4b) and (gemma3:4b)

• When prompting the AI, test its knowledge by asking

it basic questions first, then increase the complexity

and difficulty of the query task. (for example, to find

out about how Aeration System in wastewater plant

works, you need to prompt the AI to list out all the

plants in Singapore first, then filter the result by type

of aeration blower, then by manufacturer, etc)

• Subsequent prompt on the same or related subject

will result in faster output and response from the AI

• ALWAYS CHECK the OUTPUT! AI Can make mistakes

by using outdated assumptions or outdated

information. So check every step of the information

output by the AI for accuracy

Training AI Models

(Private AI and

Local AI)

• The AI will learn the CONTEXT of the information

your frequently requested.

• The more prompts and corrections you made into

the AI, the faster it learns and the higher the

accuracy of its output on the subject or context
