What’s Falcon AI?

Falcon AI, primarily Falcon LLM 40B, is a Massive Language Mannequin launched by the UAE’s Know-how Innovation Institute (TII). The 40B signifies the 40 Billion parameters utilized by this Massive Language Mannequin makes use of. The TII has even developed a 7B, i.e., 7 billion parameters mannequin that’s educated on 1500 billion tokens. Compared, the Falcon LLM 40B mannequin is educated on 1 trillion tokens of RefinedWeb. What makes this LLM totally different from others is that this mannequin is clear and Open Supply.

The Falcon is an autoregressive decoder-only mannequin. The coaching of Falcon AI was on AWS Cloud constantly for 2 months with 384 GPUs hooked up. The pretraining information largely consisted of public information, with few information sources taken from analysis papers and social media conversations.

Why Falcon AI?

Massive Language Fashions are affected by the information they’re educated on. Their sensitivity varies with altering information. We custom-made the information used to coach Falcon, which included extracts of high-quality information taken from web sites (RefinedWeb Dataset). We carried out varied filtering and de-duplication processes on this information along with utilizing available information sources. The Falcon’s structure makes it optimized for inference. The Falcon clearly outperforms the state-of-the-art fashions like Google, Anthropic, Deepmind, LLaMa, and so on., within the OpenLLM Leaderboard.

Other than all this, the primary differentiator is that it’s open-sourced, thus permitting for business use with no restrictions. So anybody can finetune Falcon with their information to create their utility from this Massive Language Mannequin. Falcon even comes with Instruct variations referred to as Falcon-7B-Instruct and Falcon-40B-Instruct, which come finetuned on conversational information. These could be labored with on to create chat purposes.

First Look: Falcon Massive Language Mannequin

On this part, we will probably be attempting out one of many Falcon’s fashions. The one we are going to go together with is the Falcon-40B Mannequin, which tops the OpenLLM Leaderboard charts. We’ll particularly use the Instruct model of Falcon-40B, that’s, the Falcon-40B-Instruct, which has already been finetuned on the conversational information, so we are able to shortly get began with it. One method to work together with the Falcon Instruct mannequin is thru the HuggingFace Areas. HuggingFace has created a House for the Falcon-40B-Instruct Mannequin referred to as the Falcon-Chat demo. Click on here to go to the positioning.

After opening the positioning, scroll right down to see the chat part, which is analogous to the pic above. Within the “Sort an enter and press Enter” subject, enter the question you wish to ask the Falcon Mannequin and press Enter to start out the dialog. Let’s ask a query to the Falcon Mannequin and see its output.

In Picture 1, we are able to see the response generated. That was response from the Falcon-40B mannequin to the question. We have now seen the working of Falcon-40B-Instruct within the HuggingFace Areas. However what if we wish to work with it in a selected code? We will do that by utilizing the Transformers library. We’ll undergo the mandatory steps now.

Obtain the Packages

!pip set up transformers speed up einops xformers

We set up the transformers package deal to obtain and work with the state-of-the-art fashions which might be pre-train, just like the Falcon. The speed up package deal permits us to run PyTorch fashions on whichever system we’re working with, and at present, we’re utilizing Google Colab. The einops and xformers are the opposite packages that help the Falcon mannequin.

Now we have to import these libraries to obtain and begin working with the Falcon mannequin. The code will probably be:

from transformers import AutoTokenizer, AutoModelForCausalLM
import transformers
import torch


mannequin = "tiiuae/falcon-7b-instruct"


tokenizer = AutoTokenizer.from_pretrained(mannequin)


pipeline = transformers.pipeline(
    "text-generation",
    mannequin=mannequin,
    tokenizer=tokenizer,
    torch_dtype=torch.bfloat16,
    trust_remote_code=True,
    device_map="auto",
    max_length=200,
    do_sample=True,
    top_k=10,
    num_return_sequences=1,
    eos_token_id=tokenizer.eos_token_id
)

Steps

• Firstly, we have to present the trail to the mannequin that we are going to be testing. Right here we will probably be working with the Falcon-7B-Instruct mannequin as a result of it takes much less house in GPU and could be can with the free tier within the Google Colab.
• The Falcon-7B-Instruct Massive Language Mannequin hyperlink is saved within the mannequin variable.
• To obtain the tokenizer for this mannequin, we write the from_pretrained() methodology from the AutoTokenizer class current in transformers.
• To this, we offer the LLM path, which then downloads the Tokenizer that works for this mannequin.
• Now we create a pipeline. When creating the pipelines, we offer the mandatory choices, just like the mannequin we’re working with and the kind of mannequin, i.e., “text-generation” for our use case.
• The kind of tokenizer and different parameters are offered to the pipeline object.

Let’s strive observing Falcon’s 7B instruct mannequin output by offering the mannequin with a question. To check the Falcon mannequin, we are going to write the under code.

sequences = pipeline(
   "Create an inventory of three essential issues to cut back international warming"
)


for seq in sequences:
    print(f"Outcome: {seq['generated_text']}")
    

We requested the Falcon Massive Language Mannequin to checklist the three essential issues to cut back international warming. Let’s see the output generated by this mannequin.

We will see that the Falcon 7B Instruct mannequin has produced outcome. It identified the basis issues for the reason for international warming and even offered the suitable resolution for tackling the problems, thus lowering international warming.

Falcon AI with LangChain

Langchain is a Python Library that helps in constructing purposes with Massive Language Functions. LangChain has a pipeline referred to as HuggingFacePipeline for fashions hosted in HuggingFace. So virtually, it should be potential to make use of Falcon with LangChain.

Set up LangChain Bundle

!pip set up langchain

This can obtain the newest langchain package deal. Now, we have to create a Pipeline for the Falcon mannequin, which we are going to achieve this by

from langchain import HuggingFacePipeline


llm = HuggingFacePipeline(pipeline = pipeline, model_kwargs = {'temperature':0})

• We name the HuggingFacePipeline() object and go the pipeline and the mannequin parameters.
• Right here we’re utilizing the pipeline from the “First Look: Falcon Massive Language Mannequin” part.
• For the mannequin parameters, we’re offering the temperature a worth of 0, which makes the mannequin not hallucinate a lot(creating its personal solutions).
• All this, we go to a variable referred to as llm, which shops our Massive Language Mannequin.

Now we all know that LangChain accommodates PromptTemplate, which permits us to change the solutions produced by the Massive Language Mannequin. And we now have LLMChain, which chains the PromptTempalte and the LLM collectively. Let’s write code with these strategies.

from langchain import PromptTemplate,  LLMChain


template = """
You're a clever chatbot. You reply must be in a humorous approach.
Query: {question}
Reply:"""
immediate = PromptTemplate(template=template, input_variables=["query"])


llm_chain = LLMChain(immediate=immediate, llm=llm)

Steps

• Firstly, we outline a template for the Immediate. The template describes how our LLM ought to behave, that’s, the way it ought to reply the questions given by the consumer.
• That is then handed to the PromptTemplate() methodology and saved in a variable
• Now we have to chain the Massive Language Mannequin and the Immediate collectively, which we achieve this by offering them to the LLMChain() methodology.

Now our mannequin is prepared. In response to the Immediate, the mannequin should funnily reply a given query. Let’s do that with an instance code.

question = "How you can attain the moon?"


print(llm_chain.run(question))

So we gave the question “How you can attain the moon?” to the mannequin. The reply is under:

The response generated by the Falcon-7B-Instruct mannequin is certainly humorous. It adopted the immediate given by us and generated the suitable reply to the given query. That is simply one of many few issues that we are able to obtain with this new Open Supply Mannequin.
