Transcripts
hello all my name is krishak and welcome
to my YouTube channel so guys I'm
starting a new playlist on an amazing
framework which is called as Lama index
now from past couple of months I've been
focusing more on generative AI uploading
amazing videos implementing multiple end
to end projects with the help of llm
models so we have discussed already
about open AI llm models we have
discussed about Frameworks like langin
we have created a lot of end to end
projects not only that we have also seen
open source llm models like Lama 2 from
meta we have also used hugging face
libraries we have seen how to do the
deployment and finally we have also
implemented multiple end to-end projects
with the help of Google gini pro and
Google gini Pro Vision all these things
we have specifically done now one more
important framework that I'm going to
discuss about is called as Lama index
again in this playlist there will be a
series of videos and again we will see
that how we can use Lama index and even
Lan framework and create some amazing
endtoend projects and harness the power
of the llm models all those things will
be covered now in this video I'm going
to discuss about two important things
what is Lama Index right and the second
thing which many people still have a lot
of confusion like what is the exact
difference between Lama index framework
and Lang chain not only that we'll also
discuss about one simple architecture of
a project if you're combining Lama index
and Lang chain how your project
architecture will look like and
specifically because many people think
that Lama index is also used to create
an end to end gen project it is uh
langin is also used to create an end to
end gen projects or generative AI
projects yes it is used but specifically
in those architecture where exactly is
Lama index used because Lama index is
very good at something which I will be
discussing about it and Lang chain is
super important and beneficial for Sim
some different applications in a
specific project so both these things
will get covered now let me go ahead and
share my screen uh just to keep a target
for this particular video guys please
let's hit like and keep the Target to
th000 likes at least because all these
videos are completely for free and as I
said that I want to democratize the
entire AI education so please do help me
in that so here exactly it is like here
is the Lama index page itself as I said
two important things I'm going to
discuss right what exactly is Lama index
why it is super beneficial and the
second thing is we'll compare the
differences between Lama index and Lang
chain and with respect to a project
architecture where exactly is llama
index used and where exactly Lang chain
used everything I'll be discussing about
it now first to First over here this
diagram will actually help you to
understand where does Lama index
actually work whenever guys uh in your
application many people have different
custom data right let's say it be
companies let it be uh it can be
different different data itself data
source itself like like YouTube apis PDF
it can be Notions it can be SQL and this
side you can probably see all the llm
models now if you have specific custom
data now let's see the definition Lama
index is a simple flexible data
framework for connecting custom data
sources to large language models now to
connect this entire data source to this
large language models right that is
where in those pipeline Lama index can
be used beneficially see with the help
of Lama index we can create an end to
end project but its core important
feature is connecting the custom data to
the llm models now how do we connect
this you know we take this entire data
we perform something called as indexing
using Lama index and then once we create
those indexing right then we will be
able to query from that index because it
creates the necessary metadata itself
right this entire Lama index library and
then when we quiring anything we'll be
able to get the response quickly right
we'll still discuss about multiple
points with various features what what
is the difference between Lama index and
Lang chain but here I hope you got an
idea llama index is a simple flexible
data framework for connecting custom
data source to large language models
okay some of the functionalities uh
you'll be able to see we'll be able to
create document Q&A data argumented chat
B knowledge agents structured analysis
many more things we'll be able to create
and the same thing we also able to
create with the help of Lang chain but
what exactly is the difference and in
the entire project architecture which
pipeline we specifically use Lama index
and that is where you'll be able to see
over here in this three important steps
we specifically use one is the data inje
that basically means it provides you lot
of libraries to connect with your
external data of different different
data sources like apis PDF document SQL
Etc then after ingesting the data it
helps you perform data indexing again
store and index your data for different
use cases integrate with Downstream
Vector store and and database providers
and the third step is with respect to
query interface Lama index provides a
pro uh query interface that accepts any
input prompt over your data and returns
a knowledge augmented response so from
that index whenever you put any queries
you'll be able to get a good response
not only good quicker response it is
quite fast so if I consider L index if
you tell me Chris tomorrow if in a
project if it someone tells you to use l
index where's specifically you're going
to use in this three steps right now
once we get this response we can further
connect this to any llm powered app or
llm models itself and based on the
prompt engineering that we do a prompt
template we can do we get a specific
response and there we can specifically
use langin again I will be discussing as
I go ahead so I hope you got an idea
with respect to this whenever we talk
about Lama Index this three kind of data
you can easily connect to it one is
unstructured data structured data and
semi- structured data right it come it
it it supports all the this three
different types of data itself now let
me quickly go ahead and talk about some
of the important differences between
Lama index and Lang chain now guys this
differences is super beneficial why I'm
telling you because in interviews in
projects when you implement you should
know what is the thing that you should
really use and finally after discussing
this differences can we use Jama index
and Lang chain together in a specific
llm powered app and that kind of
architecture also I will discuss about
so over
here all the differences that you'll be
seeing and remember guys this uh I have
referred it from di dw. a website so
this is another blogging website over
there where they they put a lot of
information regarding generative AI so
again the references from here I've
taken the screenshot from there and but
I'll explain it from my way okay
so over here based on the features here
you'll be able to see here you have Lama
index here you have Lang Lang chain as
you know both of them are Frameworks
right and these are specifically used
with multiple llm models but if I talk
about what is the primary focus of Lama
index so here you'll be able to see
intelligent search and data indexing
along with retrieval that three points
that I specifically discussed about in
case of Lang chain it helps you build a
wide range of gen applications right
what all different different all
different different functionalities J
application will help you to create if I
talk with respect to data handling Lama
index helps you in ingesting structuring
and accessing private or domain specific
data right it will be able to help you
do all these functionalities in case of
Lang chain loading processing and
indexing data for various use cases see
here also you can do indexing but with
the help of Lama Index this this
indexing that we are specifically doing
it is very much efficient over here
right why I will show you when I
probably develop a project in my
upcoming videos upcoming series of
videos okay now if I talk with respect
to customization it offers tools for
integrating private data into llms
whereas in Lang chain you can see highly
customizable it allows users to chain
multiple tools and components right what
is this multiple chain multiple tools
and components I'll discuss about when I
talk about the architecture in case of
flexibility but here again we talking
about some data and integrating that
data with our llm right mostly with
respect to Lama index if I talk with
respect to flexibility specialized for
efficient and fast search see this is
what is very much amazing in this
efficient and fast search the kind of
indexing the kind of metadata that is
created using Lama index actually helps
us to query that data efficiently
and with less response time right in
case of Lang chin general purpose
framework with more flexibility in
application
behavior let's see with respect to llm
model which all llm models is being
connect uh it can probably support so it
connects to almost most of the llm pro
providers like open AI anthropic hugging
face uh AI 21 Labs right in case of Lang
chain it supports 60 llm models so it is
pretty much good it is more than when
comp to the Llama index now you may be
saying Krish I'm talking all good points
about Lang chain what about llama index
guys exact distinguish I'm trying to
talk about the exact differences right
and once I probably compare compare all
these particular uh differences then
you'll be able to understand as soon as
you see the architecture so use cases
here you can probably see best for
application that require quick data
lookup and retrieval again quick data
lookup and interval suitable for
application that require complex
interaction like chat BS and need to
remember the memory gqs summarization
many more then integration functions as
a Smart Storage
mechanism Smart Storage mechanism why
this Smart Storage I'm saying because in
the projects also we will create this
okay designed to bring multiple to tools
uh together and chain operations right
again it is python based it is python
based it is Lama index. TX in case of
front end here you have Lang chain doj
focused on search Centric application
now this is the most important thing a
broad range of application here whenever
we talk about search Centric application
this is the thing right many people will
be talking about rag system RG right you
know I hope everybody knows about rag
system if you have an external customer
data custom data how can you probably
explore that data if you have multiple
PDFs document how can you ask any
question to that and probably retrieve
the data itself with the help of Lang
chin we can do it but if you using Lama
index we'll still get more efficient
results and I'm just not saying because
it'll just provide functionalities to
load all the PDF convert uh index those
PDFs take out all the text Data index in
such a way that whenever you uh ask for
any query you'll be able to get the
retrieval very much quicker and then for
deployment it is idal for both of them
it is the deployment part see at the end
of the day our main aim is always to
create an application using llama
index Plus langin
as I told you guys if I probably
consider this okay now let me show you
an architecture here so here is what if
we are
using llama
index plus Lang chain now this is what
is the architecture that I'm talking
about so here you can see let's go from
here this is your data right structured
unstructured and programmatic all this
data is basically indexed right this
indexing basically happens with the help
of Lama Index right once this indexing
is happened right this this entire
pipeline this entire pipeline is
implemented using llama
Index right it is very much efficient
when compared to using Lang chin then
you will also be seeing this part this
entire application is built by Lang
chain framework now llm models can be
anything different different llm models
now let's understand this so I have my
structured unstructured programmatic
data this indexing will basically happen
with the help of Lama index now user
whenever they ask any query now since we
are indexing with the help of L andex
usually this query when we are asking we
will be quickly able to get the response
now let's say we are getting some
response over here we will use this
response along with one specific prompt
along with all the response that we have
specifically getting and then we'll send
it to our llm model and from this llm
model we will get one another response
so this entire thing can be implemented
with the help of Lang chain because here
the dependency will be with respect to
multiple agents right multi-chain agents
there may be one chain to other chain uh
there may be a requirement right uh so
all these things will specifically be
there let's say if I want to use an
application create an application which
is called text to SQL right text to SQL
now not text to SQL let's say I'll not
use text SQL let's say I have a PDF
document I have multiple PDFs document
right so PDF I will Index this data
whenever I ask for any query I will be
able to get a response now along with
this response what I can do I can create
another prompt and give it to my llm
model and make this llm model perform
any function functionality based on the
response that I'm getting over here
right and then finally I'll get the
response so if I'm specifically using
Lang chain and Lama index I will be able
to create some amazing application but
at the end of the day if someone even
asks you in the interview where exactly
is Lama index used you should
specifically say in this pipeline this
is the pipeline where it will be used
still here right and this squaring
usually happens very much faster because
the indexing technique that is used in
Lama index is completely different with
respect to Lin the way that it is
probably creating vectors Vector Mings
the way that it is creating metadata it
is completely different when compared to
Lang Lang chin and this is a kind of
expert in this matter Lang chain overall
it can do multiple things right so I
hope you like this particular video I
hope you able to understand this now in
the upcoming video we will try to create
a projects using L index and Lang chin
we'll try I'll try to show you I will
talk about multiple PDFs we'll talk
about multiple PDF how you can query it
we'll talk about amazing use cases that
we are going to discuss we'll talk about
what all functionalities you have in L
index you we'll also be talking about
Vector embeddings in Lama index uh by
using this Lama index many things will
be probably coming and what all
applications you'll be able to develop
right so yes this was it for my side I
think I hope you like this particular
video I'll see you all in the next video
have a great day thank you one all take
care bye-bye
