The Know-how Innovation Institute (TII) in Abu Dhabi launched its subsequent sequence of Falcon language fashions on Could 14. The brand new fashions match the TII mission as expertise enablers and can be found as open-source fashions on HuggingFace. They launched two variants of the Falcon 2 fashions: Falcon-2-11B and Falcon-2-11B-VLM. The brand new VLM mannequin guarantees distinctive multi-model compatibilities that carry out on par with different open-source and closed-source fashions.
Mannequin Options and Efficiency
The latest Falcon-2 language mannequin has 11 billion parameters and is educated on 5.5 trillion tokens from the falcon-refinedweb dataset. The newer, extra environment friendly fashions compete effectively in opposition to the Meta’s latest Llama3 mannequin with 8 billion parameters. The outcomes are summarized within the beneath desk shared by TII:

As well as, the Falcon-2 mannequin fares effectively in opposition to Google’s Gemma with 7 billion parameters. Gemma-7B outperforms the Falcon-2 common efficiency by solely 0.01. As well as, the mannequin is multi-lingual, educated on generally used languages inclduing English, French, Spanish and German amongst others.
Nonetheless, the groundbreaking achievement is the discharge of Falcon-2-11B Imaginative and prescient Language Mannequin that provides picture understanding and multi-modularity to the identical language mannequin. The image-to-text dialog functionality with comparable capabilities with latest fashions like Llama3 and Gemma is a big development.
The best way to Use the Fashions for Inference
Let’s get to the coding half so we will run the mannequin on our native system and generate responses. First, like another venture, allow us to arrange a recent setting to keep away from dependency conflicts. Given the mannequin is launched just lately, we are going to the necessity the most recent variations of all libraries to keep away from lacking assist and pipelines.
Create a brand new Python digital setting and activate it utilizing the beneath instructions:
python -m venv venv
supply venv/bin/activate
Now now we have a clear setting, we will set up our required libraries and dependencies utilizing Python bundle supervisor. For this venture, we are going to use pictures out there on the web and cargo them in Python. The requests and Pillow library are appropriate for this function. Furthermore, for loading the mannequin, we are going to you employ the transformers library that has inner assist for HuggingFace mannequin loading and inference. We are going to use bitsandbytes, PyTorch and speed up as a mannequin loading utility and quantization.
To ease up the arrange course of, we will create a easy necessities textual content file as follows:
# necessities.txt
speed up # For distributed loading
bitsandbytes # For Quantization
torch # Utilized by HuggingFace
transformers # To load pipelines and fashions
Pillow # Primary Loading and Picture Processing
requests # Downloading picture from URL
We are able to now set up all of the dependencies in a single line utilizing:
pip set up -r necessities.txt
We are able to now begin engaged on our code to make use of the mannequin for inference. Let’s begin by loading the mannequin in our native system. The mannequin is obtainable on HuggingFace and the full measurement exceeds 20GB of reminiscence. We can’t load the mannequin in client grade GPUs which often have round 8-16GB RAM. Therefore, we might want to quantize the mannequin i.e. we are going to load the mannequin in 4-bit floating level numbers as an alternative of the standard 32-bit precision to lower the reminiscence necessities.
The bitsandbytes library offers a simple interface for quantization of Massive Language Fashions in HuggingFace. We are able to initalize a quantization configuration that may be handed to the mannequin. HuggingFace internally handles all required operations and units the proper precision and changes for us. The config may be set as follows:
from transformers import BitsAndBytesConfig
quantization_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_quant_type="nf4",
# Authentic mannequin assist BFloat16
bnb_4bit_compute_dtype=torch.bfloat16,
)
This permits the mannequin to slot in underneath 16GB GPU RAM, making it simpler to load the mannequin with out offloading and distribution. We are able to now load the Falcon-2B-VLM. Being a multi-modal mannequin, we might be dealing with pictures alongside textual prompts. The LLava mannequin and pipelines are designed for this function as they permit CLIP-based picture embeddings to be projected to language mannequin inputs. The transformers library has built-in Llava mannequin processors and pipelines. We are able to then load the mannequin as beneath:
from transformers import LlavaNextForConditionalGeneration, LlavaNextProcessor
processor = LlavaNextProcessor.from_pretrained(
"tiiuae/falcon-11B-vlm",
tokenizer_class="PreTrainedTokenizerFast"
)
mannequin = LlavaNextForConditionalGeneration.from_pretrained(
"tiiuae/falcon-11B-vlm",
quantization_config=quantization_config,
device_map="auto"
)
We go the mannequin url from the HuggingFace mannequin card to the processor and generator. We additionally go the bitsandbytes quantization config to the generative mannequin, so will probably be routinely loaded in 4-bit precision.
We are able to now begin utilizing the mannequin to generate responses! To discover the multi-modal nature of Falcon-11B, we might want to load a picture in Python. For a check pattern, allow us to load this normal picture out there right here. To load a picture from an internet URL, we will use the Pillow and requests library as beneath:
from Pillow import Picture
import requests
url = "https://static.theprint.in/wp-content/uploads/2020/07/football.jpg"
img = Picture.open(requests.get(url, stream=True).uncooked)
The requests library downloads the picture from the URL, and the Pillow library can learn the picture from bytes to a regular picture format. Now that may have our check picture, we will now generate a pattern response from our mannequin.
Let’s arrange a pattern immediate template that the mannequin is delicate to.
instruction = "Write a long paragraph about this picture."
immediate = f"""User:<image>n{instruction} Falcon:"""
The immediate template itself is self-explanatory and we have to observe it for finest responses from the VLM. We go the immediate and the picture to the Llava picture processor. It internally makes use of CLIP to create a mixed embedding of the picture and the immediate.
inputs = processor(
immediate,
pictures=img,
return_tensors="pt",
padding=True
).to('cuda:0')
The returned tensor embedding acts as an enter for the generative mannequin. We go the embeddings and the transformer-based Falcon-11B mannequin generates a textual response primarily based on the picture and instruction offered initially.
We are able to generate the response utilizing the beneath code:
output = mannequin.generate(**inputs, max_new_tokens=256)
generated_captions = processor.decode(output[0], skip_special_tokens=True).strip()
There now we have it! The generated_captions variable is a string that incorporates the generated response from the mannequin.
Outcomes
We examined varied pictures utilizing the above code and the responses for a few of them are summarized on this picture beneath. We see that the Falcon-2 mannequin has a robust understanding of the picture and generates legible solutions to indicate its comprehension of the eventualities within the pictures. It will possibly learn textual content and likewise highlights the worldwide data as a complete. To summarize, the mannequin has glorious capabilities for visible duties, and can be utilized for image-based conversations.

License and Compliance
Along with being open-source, the fashions are launched with the Apache2.0 License making them out there for Open Entry. This permits the modification and distribution of the mannequin for private and business makes use of. This implies that you may now use Falcon-2 fashions to supercharge your LLM-based purposes and open-source fashions to offer multi-modal capabilities in your customers.
Wrapping Up
General, the brand new Falcon-2 fashions present promising outcomes. However that’s not all! TII is already engaged on the following iteration to additional push efficiency. They appear to combine the Combination-of-Specialists (MoE) and different machine studying capabilities into their fashions to enhance accuracy and intelligence. If Falcon-2 looks as if an enchancment, be prepared for his or her subsequent announcement.
