RAG Empowerment: Cohere C4AI Command-R and Transformers Unveiled

Community Article Published April 7, 2024

Introduction

In the realm of cutting-edge AI models, Cohere C4AI Command-R stands tall as a beacon of innovation. Boasting a staggering 35 billion parameters, this non-quantized marvel represents the pinnacle of generative models, pushing the boundaries of what's possible in natural language processing. Developed jointly by Cohere and Cohere For AI, Command-R is not merely a tool but a revolution in itself, redefining the landscape of language understanding and generation.

Understanding the Terminology

Before delving into the depths of this groundbreaking technology, let's shed light on a few key terms:

C4AI Command-R : A research release of a highly performant generative model, equipped with open weights and optimized for various use cases including reasoning, summarization, and question answering. With multilingual generation capabilities evaluated across 10 languages and robust RAG (Retrieval-Augmented Generation) capabilities, Command-R stands as a versatile powerhouse in the AI domain.
Transformers : In the realm of natural language processing, transformers represent a paradigm shift. These models leverage self-attention mechanisms to weigh the importance of different words in a sentence, enabling them to capture long-range dependencies and contextual information effectively. Transformers have emerged as the backbone of numerous state-of-the-art AI models, including the formidable Command-R.

Integration Benefits

The fusion of Cohere C4AI Command-R with transformers heralds a new era of possibilities, unlocking a myriad of benefits:

Enhanced Performance: By harnessing the power of transformers, Command-R achieves unprecedented levels of performance across various NLP tasks. The self-attention mechanism enables the model to grasp intricate linguistic nuances and generate coherent, contextually relevant responses with remarkable accuracy.
Scalability: The modular architecture of transformers facilitates seamless scalability, allowing Command-R to accommodate larger datasets and tackle complex linguistic challenges with ease. This scalability ensures that the model can adapt to evolving requirements and deliver consistent performance across diverse domains.
Efficient Training: Transformers streamline the training process by enabling parallelization and efficient utilization of computational resources. This not only accelerates the training phase but also enhances the overall efficiency of Command-R, enabling rapid iterations and experimentation.
Interpretability: The attention mechanisms employed by transformers offer insights into the model's decision-making process, enhancing interpretability and enabling stakeholders to gain deeper insights into the underlying patterns within the data. This transparency fosters trust and facilitates collaboration between AI systems and human users.

Code Implementation

The seamless integration of Cohere C4AI Command-R with transformers requires careful implementation and configuration to harness the full potential of these powerful technologies. Below, we outline the key steps involved in incorporating Command-R and transformers into your AI workflow:

Step I: Install Libraries

pip install torch transformers accelerate sentencepiece protobuf bitsandbytes -qU

Step II: Transformers Generation + RAG Capabilities

from transformers import AutoTokenizer, AutoModelForCausalLM, TextStreamer

model_id = "CohereForAI/c4ai-command-r-v01-4bit"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)

# Using the text streamer to stream output one token at a time
streamer = TextStreamer(tokenizer, skip_prompt=True, skip_special_tokens=True)

# define documents to ground on:
documents = [
    { "title": "Tall penguins", "text": "Emperor penguins are the tallest growing up to 122 cm in height." }, 
    { "title": "Penguin habitats", "text": "Emperor penguins only live in Antarctica."}
]

generation_params = {
    "do_sample": True,
    "temperature": 0.7,
    "top_p": 0.95,
    "top_k": 40,
    "max_new_tokens": 512,
    "repetition_penalty": 1.1
}

# render the tool use prompt as a string:
grounded_generation_prompt = tokenizer.apply_grounded_generation_template(
    conversation,
    documents=documents,
    citation_mode="accurate", # or "fast"
    tokenize=False,
    add_generation_prompt=True,
)

input_ids = tokenizer.encode(
    grounded_generation_prompt,
    add_special_tokens=False,
    return_tensors="pt"
)

# Generate streamed output
output_ids = model.generate(
    input_ids.to(model.device),
    streamer=streamer,
    **generation_params
)
output = tokenizer.decode(
    output_ids[0][input_ids.size(1) :],
    skip_special_tokens=True
)

Output

Relevant Documents: 0,1
Cited Documents: 0,1
Answer: The emperor penguin is the tallest species of penguin, growing up to 122cm in height. They only live in Antarctica.
Grounded answer: The <co: 0>emperor penguin</co: 0> is the tallest species of penguin, growing <co: 0>up to 122cm in height.</co: 0> They <co: 1>only live in Antarctica.</co: 1>

Conclusion

In essence, the integration of Cohere C4AI Command-R with transformers represents a watershed moment in the realm of natural language processing. This synergy between state-of-the-art technologies not only elevates the performance and versatility of Command-R but also paves the way for transformative applications across diverse domains. As we embark on this journey of innovation and discovery, let us harness the power of AI to unlock new frontiers of knowledge and understanding, shaping a future where intelligence knows no bounds.
