Keywords

💡Olama

Olama is the central subject of the video, which appears to be a software or platform being introduced in the course. It is implied to be a complex system with various functionalities and models that users can interact with. The script guides viewers through the basic steps of getting started with Olama, including installation and model interaction.

💡Model

In the context of the video, a 'model' refers to a component within the Olama system, likely an AI model with specific capabilities. Models are made up of various layers and parameters, and they can be downloaded and interacted with through the Olama interface. The script mentions different models like '53' and 'Intern LM', each with unique characteristics.

💡Discord

Discord is mentioned as a platform where users can join to ask questions and receive support related to Olama. It serves as a community hub for users to engage with one another and the developers, highlighting the collaborative aspect of the Olama ecosystem.

💡GitHub

GitHub is referenced as the location for the source code and documentation of Olama. It is a platform where developers can contribute to the project and report issues. However, the script differentiates between using GitHub for actual project issues and Discord for support queries.

💡Weights and Biases

Weights and biases are fundamental to the concept of a model in the video. They represent the connections and fine-tuning within an AI model, influencing how different concepts or nodes within the model relate to one another. The script explains that these parameters are crucial for the model's training and functionality.

💡Quantization

Quantization is a process mentioned in the script that involves reducing the precision of the numbers used to represent the model's parameters. It is used to make models more accessible by reducing the amount of VRAM (Video RAM) required to run them, trading off some precision for efficiency.

💡REPPLE

REPPLE, standing for Read Eval Print Loop, is an interactive coding environment within Olama where users can input commands or questions and receive immediate responses. It is showcased in the script as a way to interact with the models and demonstrates the system's interactivity.

💡Token

A 'token' in the script refers to a unit of text, such as a word or part of a word, that the model generates in response to a query. The generation process is described as streaming out token by token, highlighting the incremental nature of the model's responses.

💡Context Window

The context window is the amount of conversation history that the model can remember during an interaction. It is limited in size, with the script mentioning 248 tokens as the default for Olama models, affecting the continuity and depth of the conversation that can be maintained.

💡CLI (Command Line Interface)

The CLI is the textual interface through which users interact with Olama, as demonstrated in the script when the user types commands to exit the REPPLE or to list models. It is a common way to interact with software, providing a direct and flexible means of control.

💡VRAM

VRAM, or Video RAM, is the memory used by the graphics processing unit (GPU) to store image data. In the context of the video, it refers to the amount of memory required to run the AI models within Olama, with quantization affecting the VRAM usage.

play00:01

hi I'm Matt I want to help you get up to

play00:03

speed on what olama is all about in this

play00:06

free course you're going to learn all

play00:08

the different aspects of olama and what

play00:10

you can do with it this first video will

play00:12

just get you started in the most basic

play00:14

way we'll install a llama verify it's

play00:17

running download a model try out a

play00:19

prompt and find and download another

play00:22

model it's not going to be everything

play00:25

but that'll come as the rest of the

play00:27

course is released so let's get started

play00:29

first first thing we want to do is visit

play00:31

the ama.com web page you can also get to

play00:34

this by going to ol. a because all the

play00:38

cool kids have a URLs okay let's take a

play00:42

quick look at what's on this page at the

play00:44

top we have a link to the Discord you

play00:46

can join and ask any questions you have

play00:49

and you'll probably get a decent answer

play00:52

GitHub has the source code and

play00:53

documentation for olama which you can

play00:55

review but if you have an issue with

play00:57

olama it's best to keep the question

play00:59

questions on the Discord and not the

play01:02

GitHub issues GitHub issues are for

play01:04

actual problems in the project and not

play01:07

really support issues start out the

play01:10

question in the Discord and if you need

play01:12

to escalate GitHub is a great place to

play01:14

go the search box will let you search

play01:17

for both official models and user

play01:19

contributed models we'll talk more about

play01:21

models soon next to that is the link to

play01:25

the community models since I'm logged in

play01:27

you can see my username on AMA this is

play01:29

is all model related and we'll come back

play01:32

to

play01:32

that down at the bottom we can see a

play01:35

link to the docs which is just a folder

play01:37

on the GitHub one other interesting link

play01:40

is to meetups and these are events held

play01:43

around the world with the AMA team keep

play01:46

an eye out there may be one close to you

play01:48

at some point in the future so right in

play01:51

the middle is a link to download olama

play01:54

click that to get three choices Mac

play01:56

Linux and windows I'll go into more

play01:59

detail on this in another video but just

play02:01

choose your platform and follow the

play02:03

instructions I'm on a Mac right now so

play02:06

I'll click the download button and then

play02:07

run the installer so once it's installed

play02:11

there are a few different things you can

play02:13

do to ensure that olama is running the

play02:16

easiest is just to run olama run 53

play02:20

that's f as in Phi and the number three

play02:24

the reason I chose that model is that

play02:26

it's short and easy to spell and small

play02:29

so we can be up and running quickly you

play02:31

probably don't have the model so you'll

play02:33

see it download the various layers of

play02:35

the model you'll learn more about layers

play02:38

later in this course if you're on a Mac

play02:41

or Windows and the olama service wasn't

play02:43

running just running olama run will

play02:46

start up that service if however you're

play02:49

on Linux and the olama Run command fails

play02:52

you may not have the service running you

play02:54

can refer to this page to get a little

play02:56

bit more information about how to get it

play02:57

started it's always best to let the

play02:59

service run that piece rather than

play03:01

running it locally in a command prompt

play03:03

that you start so at this point you may

play03:06

still have to wait a little bit longer

play03:08

for that model to download so let's talk

play03:10

for a moment about what a model is a

play03:13

model is made up of a number of pieces

play03:16

the biggest of which is the weights file

play03:18

this is a collection of nodes and they

play03:20

have connections between them called

play03:22

weights and biases those weights and

play03:24

biases combined are referred to as

play03:27

parameters a node is often a a concept

play03:30

maybe a word or a phrase and when the

play03:33

model is trained the parameters connect

play03:35

each of these different concepts

play03:37

together by different amounts and

play03:39

sometimes they get a little closer and

play03:41

other times they get a little further

play03:43

away as the model is trained more and

play03:45

more two nodes won't just have one

play03:48

weight between them they might have many

play03:51

combinations of Weights depending on the

play03:52

context of what the node does although

play03:55

it feels like magic this is how much of

play03:58

the world's knowledge can be stuffed

play04:00

into a relatively tiny little file how

play04:03

big that file is depends on how the

play04:05

parameters are represented when the file

play04:08

is originally developed it's probably

play04:10

going to use 16 or 32-bit floating Point

play04:12

numbers these can be incredibly big and

play04:15

precise but if we group those numbers

play04:17

into smaller sets we can abstract them

play04:20

down to much smaller numbers while

play04:22

retaining an incredible amount of

play04:23

precision the most common amount is four

play04:26

and that's what's referred to as 4-bit

play04:28

quantization

play04:30

there'll be a more advanced video in

play04:32

this course that goes into a lot more

play04:34

detail about quantization in the future

play04:37

when each parameter is represented by a

play04:38

32-bit number llama 38b or 8 billion

play04:42

parameters will take roughly 32 gigs of

play04:44

vram to run because there are eight bits

play04:47

in a bite four bytes perameter so 8

play04:51

billion Time 4 adds up to roughly 32 GB

play04:55

there's some extra overhead as well but

play04:57

that's the simple way of calculating it

play04:59

if we quantize to 4 bits per parameter

play05:02

that gets close to four to 5 GB of vram

play05:05

required which is a whole lot more

play05:08

accessible there are a few other

play05:09

components to the model and we'll cover

play05:11

that later in this course so after all

play05:14

that your model should be downloaded and

play05:16

ol will have dropped you into the

play05:18

repple reppel is a coding concept and

play05:21

means read eval print Loop this is a

play05:24

place that you can enter some code

play05:26

interactively and it'll be processed

play05:27

right away and in the ol reppel we can

play05:30

enter a question and get it answered

play05:33

immediately so try asking a question why

play05:36

is the sky blue and within a few seconds

play05:38

the model will spit out or generate an

play05:41

answer the answer is streamed out token

play05:44

by token a token is a word or common

play05:47

part of a word and there are a number of

play05:49

factors that go into how long that

play05:51

generation will take you can continue

play05:53

the conversation and the model will

play05:55

remember much of what was said limited

play05:57

by the size of the context window that

play05:59

the models supports often this contact

play06:02

size is 248 tokens by default inama

play06:05

models but that's easily modifiable if

play06:08

your conversation goes longer than 248

play06:11

tokens the model will start to forget

play06:13

the earlier parts of the

play06:15

conversation and if you restart the CLI

play06:17

or reppel that entire history will be

play06:20

wiped often users will work with olama

play06:23

through a thirdparty UI open web UI is a

play06:26

common one as is Misty and so many

play06:28

others one thing some of the uis offer

play06:31

is better ways of leveraging memory so

play06:34

you can continue those conversations for

play06:35

longer we'll see that in future topics

play06:38

now back at the command line type

play06:41

slby to exit out of the reppel let's go

play06:45

to the ama.com website and click on

play06:47

models right now the list of models is

play06:50

sorted by featured try sorting by newest

play06:53

one of the more recent models at the

play06:55

time of this recording is intern LM

play06:58

which attempts to be better at math and

play07:00

math reasoning that's not actually

play07:02

saying that much because models tend to

play07:04

be terrible at these things and aren't

play07:07

the best tool to use thankfully it's

play07:09

also good at all the usual things models

play07:12

do so click on the link for intern LM we

play07:15

have a few bits of info on this page

play07:17

first there's a short description of the

play07:19

model we see how popular the model is as

play07:21

well as how recently it was updated then

play07:24

there's a drop down with different

play07:25

variants of the model it defaults to the

play07:28

most common one which will be a four bit

play07:29

quantize model to the right is the

play07:32

command to run to get this model below

play07:35

that is the hash of the model and the

play07:37

overall size below that we see the

play07:39

various layers of the model there's that

play07:41

layer term again and there will be more

play07:43

on that later in this course in the drop

play07:46

down with the different tags or variants

play07:48

find the one that is 7B chat B 2.5 Q2 _

play07:54

K so copy the command to run this model

play07:57

and paste it into the terminal if you're

play07:59

still running 53 then type slby to exit

play08:02

and then run that command you'll see it

play08:04

download the model which is a bit larger

play08:06

than the last one when it's done try

play08:08

asking what is a black hole and soon

play08:11

after you will get an answer describing

play08:13

a black hole in a way that's a little

play08:14

different from 53 style but what's most

play08:17

incredible about this is that this one

play08:20

has been quantized from the original

play08:22

32-bit floating Point number to a TW bit

play08:26

quantization you will usually see much

play08:28

better answers from the 4-bit model but

play08:31

it's pure magic this even works at all

play08:35

while we're still in the repple type

play08:36

slash question mark you'll get a list of

play08:39

all the commands you can run then try

play08:41

typing SL Mark shortcuts this shows us

play08:45

different keyboard shortcuts you can use

play08:47

in the reppel though I still prefer

play08:49

exiting with slby so exit the reppel

play08:52

however you prefer now type olama LS to

play08:56

see a list of your two models olama PS

play08:59

will show us which models if any are

play09:02

currently loaded models stay in memory

play09:04

for 5 minutes by default and several can

play09:06

be loaded at once depending on your

play09:08

Hardware we'll look at concurrence in

play09:10

more detail in a future video if you

play09:12

want to remove one of the models you can

play09:14

use olama RM and the model

play09:17

name there is so much more you can do

play09:19

with AMA but this video is already long

play09:21

enough watch out for the next video in

play09:24

this course coming in the next few days

play09:26

if you have any specific questions about

play09:28

what's covered in this course join us on

play09:30

a brand new Discord that you can find at

play09:32

this URL thanks so much for watching

play09:35
