Generative AI 101: When to use RAG vs Fine Tuning?
Summary
TLDRIn this episode of 'JNA 101', the host discusses the optimal use of large language models (LLMs). They explain the cost and process of fine-tuning an LLM for specific data sets, highlighting its effectiveness in niche applications like predicting crop growth based on soil data. The host contrasts this with using LLMs out-of-the-box or through retrieval (RG), which is more cost-effective and integrates well with enterprise systems. The video concludes with advice on choosing between RG and fine-tuning based on the specific needs of the business.
Takeaways
- 💡 Fine-tuning a large language model (LLM) is costly but necessary for specific use cases where you have unique data sets.
- 📚 Fine-tuning requires a clean, bias-free dataset and investment in engineering and research efforts to adjust the model properly.
- 🌱 An example of when fine-tuning is essential is in niche industries like agriculture, where predictive models for crop growth rely on proprietary data.
- 🔍 Open-source LLMs may not have learned from niche data that is not readily available on the internet, making fine-tuning a better option for such specific cases.
- 🚀 Fine-tuning is beneficial when you have access to exclusive data that can significantly enhance the LLM's performance in a particular application.
- 🤖 Using an LLM directly is suitable for general purposes like chatting with virtual assistants but lacks integration with company databases.
- 🔗 The real efficiency in enterprises comes from integrating LLMs with enterprise knowledge, such as documents and ERP systems.
- 🔍 Retrieval (RG) is an alternative to fine-tuning that involves fetching relevant facts from enterprise systems for the LLM to generate responses.
- 💰 RG is cost-effective as it doesn't require the computational resources and data preparation needed for fine-tuning.
- ⚖️ The choice between RG and fine-tuning depends on the use case; RG is suitable for general inquiries, while fine-tuning is for specific business-related cases.
- 📧 The speaker offers one-on-one discussions for further questions, encouraging viewers to reach out via social media channels.
Q & A
What is the main topic discussed in the video script?
-The main topic is the decision-making process regarding when to use a fine-tuned large language model (LLM), when to use an out-of-the-box LLM, and when to use retrieval-augmented generation (RG).
Why is fine-tuning an LLM considered costly?
-Fine-tuning is costly because it involves taking a pre-trained model, preparing a clean and bias-free dataset, and investing engineering and research resources to properly adjust the model for specific tasks.
What are the specific use cases where fine-tuning an LLM is recommended?
-Fine-tuning is recommended when there is niche data available only to a few companies or not readily available on the internet, and when the LLM needs to perform optimally on tasks that are highly specific to that data.
Can you provide an example of a scenario where fine-tuning an LLM is beneficial?
-An example is an agriculture company with decades of data on soil, nutrients, and bacteria that can be used to predict the best crop for a given land and season, which would greatly benefit from a fine-tuned LLM.
What is the primary limitation of using an out-of-the-box LLM for enterprise use?
-The primary limitation is that an out-of-the-box LLM does not integrate with a company's database and lacks the ability to make sense of enterprise-specific knowledge without additional setup.
What does RG stand for, and how does it differ from fine-tuning an LLM?
-RG stands for retrieval-augmented generation. It differs from fine-tuning by not requiring the LLM to be trained on new data but instead providing it with retrieved facts to generate responses.
Why is RG considered more efficient for large enterprises?
-RG is efficient for large enterprises because it allows the LLM to access and make sense of enterprise knowledge from documents, ERP systems, CRM, etc., without the need for fine-tuning.
What percentage of use cases can be solved with RG according to the speaker's experience?
-According to the speaker, 80% or more of use cases can be solved with RG.
How does RG help in providing accurate responses to enterprise queries?
-RG helps by retrieving relevant facts from enterprise systems and providing them to the LLM, which then uses these facts to create accurate and contextually appropriate responses.
What is the speaker's offer to viewers who have questions on this topic?
-The speaker offers to discuss one-on-one with viewers who have questions, encouraging them to reach out via social media channels for further discussion.
What is the main takeaway from the script regarding the use of LLMs in business?
-The main takeaway is that businesses should choose between fine-tuning, using an out-of-the-box LLM, or RG based on the specificity of their data and use cases, with RG being a cost-effective option for general use cases and fine-tuning for specific business-related use cases.

🤖 Fine-Tuning Large Language Models: When and Why
This paragraph discusses the considerations for using a fine-tuned large language model (LLM) versus using one out of the box. It highlights the cost and effort involved in fine-tuning a pre-trained model with a specific dataset, ensuring it is free from bias, and the potential benefits for niche applications where proprietary data is available. The speaker uses the example of an agriculture company creating an AI model to predict optimal crop growth based on soil data, emphasizing that fine-tuning is necessary for specialized use cases where off-the-shelf solutions may not suffice.
🔍 Choosing Between Direct Use and Retrieval-Augmented Generation
The second paragraph explores the practical applications of using an LLM directly versus employing Retrieval-Augmented Generation (RAG). It points out that using an LLM directly is often limited to basic interactions, such as chatting with virtual assistants, and lacks integration with company databases. In contrast, RAG is presented as a more efficient solution for enterprise use cases, allowing the LLM to access and make sense of enterprise knowledge from documents and systems. The speaker suggests that for most general use cases, RAG is a cost-effective choice, while fine-tuning is reserved for specific business-related scenarios where unique data can enhance the LLM's performance. The paragraph concludes with an invitation for further discussion on social media channels for those with questions or doubts.

hello everyone and welcome back to the
next episode of jna 101 in today's
episode we're going to discuss when do
you when should you use uh a fine-tuned
large language model when should you
just use it out of the box and when
should you use uh out of the box or
finding one with
r so
finetuning itself is a little cost
costly so you take a pre-trained model
and then you you first you need to have
your data set you need to clean it up
make sure that it is uh you know rid of
any bias or anything and then you have
to use that data set and you know spend
some money and engineering and you know
research power into fine-tuning it
properly so fine tuning is of course not
as costly as training the llm in the
first go but it is still costly as
compared to just using uh llm API or
just using an open source llm directly
or even doing RG so out of the three of
them fine tuning a fine tune llm and
creating tune llm and creating right but
there are specific use cases where you
have to do the way you should consider
doing it very recently I sat down the
CIO of a large um agriculture Agri
company and uh you know they they were
actually creating a model an AI model an
ml model
uh given a patch of land the type of
soil the type of uh you know nutrients
the type of bacteria Etc present in the
in the soil as an input you could
predict what kind of crop would go grow
the best in which season of the year
right so if you if as an agriculture
company you have data of all of this for
the last 20 30 years right you can and
of course you have the resources to
clean this data up then this is a prime
example of when to do fine tuning
because if you were to do the same in
either a direct use llm or even in RG it
will not have work it will not work as
well as a fine-tune llm on this specific
data right so if there is some Niche
data in your use case that only you have
or if you like that's very limited to a
few companies in the world and that's
not available in the uh on the internet
so easily then most probably an open-
Source llm will not have learned on it
right so it makes sense for you to use
that data set to train your own or
fine-tune your own llm right and it's
worth spending that money and time and
effort to do that as well right I've
given you two examples one in the last
uh episode and one in this one and and
there are many such examples uh of you
know when to find you now let's move on
to either using an LM directly or using
R so using an llm directly is only
useful when you have to when you want to
use it like Char GB right so you can
either use CH GPT or Bard or you know
any other freely available uh you know
virtual assistants on the web or you can
even just use an open source one and
start chatting with it but it's
basically very limited to use in your
day-to-day use because it has it does
not integrate with your company's
database right so the biggest use case
and what I have seen after speaking to a
lot of cxos globally is that the real
use case or the real unlock of
efficiency in uh efficiency in large
Enterprises using jni will only happen
when jni speaks to Enterprise knowledge
right this is knowledge in documents
knowledge in Erp systems knowledge in
CRM etc etc so you have to figure out a
way to merge them and just like freely
available lmms are not going to you know
do this for you and hence for most
Enterprise use cases RG is the best
option where you can figure out you can
do retrieval as we have discussed in the
last episode last to last episode so you
can you can do retrieval on your
Enterprise systems right and you can
throw that to an llm where that llm can
make sense of the facts that you have
provided it through uh retrieval and
then create a response accordingly
without using its own worldly knowledge
right now depending on use case to use
case you have to choose between the RG
one and the fine tuning one again
fine-tuning is useful when you have some
specific data which the world does not
have which is not available on the
internet and uh you know it is it will
make the llm better in that specific use
case right you have to do fine tuning
there and for everything else most like
I think 80% plus of the use cases that
you know my friends in the CIO and the
COO Community share with me they they
can be solved with R because RG is way
cheaper because it it does not require
you to fine tune fine tuning requires
some you know bandwidth some uh you know
uh computing power and data as well R
requires nothing it is very easy to set
up and very easy to use and uh it
grounds or you know gives facts to the
llm and says that okay you have to
remain within the facts and answer the
question that you know either your sales
team member is asking or your operation
for is asking or anyone in your company
is asking so if you most of the general
personal use cases can get solved with r
and your specific business related use
cases can be solved using fine tuning
and I'd be happy to discuss with any one
of you one-on-one if you have a question
on this so do hit me up on any of my
social media channels uh if you have a
doubt and we can have a discussion on
this as well but thank you so much for
watching everybody and have a great
day
