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. As compared, the Falcon LLM 40B mannequin is educated on 1 trillion tokens of RefinedWeb. What makes this LLM completely 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 knowledge largely consisted of public knowledge, with few knowledge sources taken from analysis papers and social media conversations.

Why Falcon AI?

Massive Language Fashions are affected by the info they’re educated on. Their sensitivity varies with altering knowledge. We custom-made the info used to coach Falcon, which included extracts of high-quality knowledge taken from web sites (RefinedWeb Dataset). We carried out numerous filtering and de-duplication processes on this knowledge along with utilizing available knowledge 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 forth., within the OpenLLM Leaderboard.

Aside from 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 knowledge to create their software 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 knowledge. These could be labored with on to create chat functions.

First Look: Falcon Massive Language Mannequin

On this part, we can be making an attempt out one of many Falcon’s fashions. The one we’ll go together with is the Falcon-40B Mannequin, which tops the OpenLLM Leaderboard charts. We are going to particularly use the Instruct model of Falcon-40B, that’s, the Falcon-40B-Instruct, which has already been finetuned on the conversational knowledge, so we will rapidly get began with it. One solution to work together with the Falcon Instruct mannequin is thru the HuggingFace Areas. HuggingFace has created a Area for the Falcon-40B-Instruct Mannequin referred to as the Falcon-Chat demo. Click on right here to go to the location.

After opening the location, scroll all the way down to see the chat part, which has similarities to the pic above. Within the “Kind an enter and press Enter” subject, enter the question you wish to ask the Falcon Mannequin and press Enter to begin the dialog. Let’s ask a query to the Falcon Mannequin and see its output.

In Picture 1, we will see the response generated. That was a very good 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 particular code? We are able to do that by utilizing the Transformers library. We are going to 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 allows us to run PyTorch fashions on whichever system we’re working with, and presently, 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 can 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’ll be testing. Right here we can be working with the Falcon-7B-Instruct mannequin as a result of it takes much less area 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 supplied to the pipeline object.

Let’s attempt observing Falcon’s 7B instruct mannequin output by offering the mannequin with a question. To check the Falcon mannequin, we’ll write the beneath code.

sequences = pipeline(
   "Create an inventory of three vital issues to scale back world warming"
)


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

We requested the Falcon Massive Language Mannequin to checklist the three vital issues to scale back world warming. Let’s see the output generated by this mannequin.

We are able to see that the Falcon 7B Instruct mannequin has produced a very good end result. It identified the basis issues for the reason for world warming and even supplied the suitable resolution for tackling the problems, thus decreasing world warming.

Falcon AI with LangChain

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

Set up LangChain Package deal

!pip set up langchain

It will obtain the most recent langchain package deal. Now, we have to create a Pipeline for the Falcon mannequin, which we’ll accomplish that 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 price 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 comprises PromptTemplate, which permits us to change the solutions produced by the Massive Language Mannequin. And we’ve 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 needs to be in a humorous manner.
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 person.
• 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 accomplish that by offering them to the LLMChain() methodology.

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

question = "The best way to attain the moon?"


print(llm_chain.run(question))

So we gave the question “The best way to attain the moon?” to the mannequin. The reply is beneath:

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 will obtain with this new Open Supply Mannequin.
