Code Llama 70B: Everything You Need to Know

Welcome to Tech Tips Tuesday ?? where we explore the latest news, announcements and trends around the tech world.

6TH FEBRUARY 2024, MENLO PARK - Code Llama 70B by Meta AI has become a technological leap in code generation. This large language model (LLM) of 70 billion parameters changes traditional tools for programming and redefines the way developers engage with software. It's not just a tool but a revolution—bringing coding to the level of ordering your morning coffee. Code Llama 70B brings together vast data and computational power to improve developer productivity like it's never been done before.

Code Llama 70B is a generative text model for code synthesis built specifically for this purpose. Its feature set is distinguished by features not characteristic of systems targeting similar tasks, such as the well-known AI coding assistant GPT-4 or GitHub Copilot. Nevertheless, while GPT-4 and GitHub Copilot do have unique good points of their own, Code Llama 70B enjoys uniqueness as follows:

• Dealing with diverse prompts: Code Llama 70B is flexible, dealing with various forms of prompts. On giving it a code snippet or the need in plain English, it is in a position to efficiently generate the relevant code.
• Generating quality code: Code Llama 70B outputs are renowned for providing quality—both accurate and efficient. It is known to produce code that works, is of high quality, and follows best practices and conventions of coding.
• Real-time collaboration: One of the inherent functionalities of Code Llama 70B is the use of real-time collaboration, by which not one but also multiple developers can work in conjunction to achieve a sole task. It is this platform that will guarantee or put weight behind teaming up in any development process

Apart from Code Llama 70B, other tools that help uplift the whole code development workflow are:

• StarCoder: Available to optimise the program and tune its performance to develop efficient and faster programs.
• CodeGen-16B-Mono: Quite appropriate for monolithic applications and removes significantly the overhead in developing large-scale software systems with automatic generation of boilerplate code.

Performance Metrics

According to HumanEval, Code Llama 70B outperforms Code Llama 34B with a score of 65.2 compared to 51.8. However, it falls short of GPT-4, which holds the top spot with an impressive score of 85.4. For reference, GPT-3.5 achieves a score of 72.3, showing its competitive standing in the field. Similar results have been reported by the MBPP benchmark.

Meta's pursuit aligns with OpenAI's discovery that the effectiveness of language models scales proportionally with the increase in model parameters. However, the inherent complexity associated with training and hosting these models has spurred the development of "compact language models." An example is the recent introduction of Stable LM 2 by Stability AI, boasting 1.9 billion parameters, which demonstrates comparable performance to Code Llama 7B but at a significantly reduced size, marking a notable advancement in efficiency and practicality.

That depth in the internals of Code Llama 70B brings understanding with it in regard to its abilities and performance to put into a notable toolset for code generation augmented by AI.

Practical Guide For Developers

For developers interested in experimenting or adopting Code Llama 70B into their workflow, here is a brief guide to get started:

Step 1: Setting Up Your Environment

Before you can start using Code Llama 70B, you'll need to ensure your development environment is properly configured:

1. Install dependencies: Begin by installing the Meta AI Python library, which provides the interface for interacting with Code Llama 70B. You can do this using pip:

pip install meta-ai        

2. Prepare your code repository: Make sure you have a well-structured code repository to store and manage your project's files. This will facilitate seamless integration with Code Llama 70B.

Step 2: Initializing Code Llama 70B

Once your environment is set up, it's time to initialise the Code Llama 70B model:

1. Import libraries: In your Python script or notebook, import the necessary libraries for interacting with Code Llama 70B:

from meta_ai import CodeLlama70B        

2. Create an instance: Instantiate the Code Llama 70B model and load its pre-trained weights:

code_llama = CodeLlama70B()        

Step 3: Providing Prompts and Generating Code

With Code Llama 70B initialised, you can now provide prompts and generate code:

1. Define your prompt: Clearly state the desired outcome or functionality you want the generated code to achieve. You can provide prompts in the form of code snippets or natural language instructions.

2. Generate code: Utilise the generate() function provided by the Code Llama 70B library to generate code based on your prompts:

prompt = "Create a function that sorts a list of integers in ascending order." 
generated_code = code_llama.generate(prompt)        

3. Review and validate: Once the code is generated, review it carefully to ensure it meets your requirements. Validate its functionality and accuracy before incorporating it into your project.

Utilising the Natural Language Processing Feature.

The use of natural language processing features is one of the most outstanding attributes of Code Llama 70B. To use this feature properly, observe the following guidelines:

• Clear and brief prompts: Be clear as to what is expected to be done or achieved and instruct particularly Code Llama 70B in its course of actions. This will make it easy for the model to understand your intention from the outset.
• Always include some context within your prompts: Relevant context of a prompt could increase the chances of code generation to be more accurate. For example, if you have code to solve an image classification problem, the context to add is information about the dataset and the desired performance metrics."
• Experiment with various formats: Code Llama 70B can handle any prompt format—be it snippets of code or plain language instructions. Play with different formats to find what works most suitably for your particular use case.

Fine-tuning for Specialized Coding

Recommendations to improve the performance of Code Llama 70B in specific coding environments include:

• Domain-related data: If you are working on computer vision tasks, collect a dataset that relates to image codes. This will help Code Llama 70B understand better and generate better codes that relate to your domain.
• Balancing pre-training and fine-tuning: Pre-training with a large-scale corpus of code-related data will help the Code Llama 70B model in learning the concept of coding in the first place. In contrast, fine-tuning with domain-specific data will further specialise this generic capacity for better performance on specialised tasks.
• After iterating and fine-tuning, the best thing is to experiment with various settings of hyperparameters, training, and datasets to determine the optimum setting for your particular coding condition.

Ethical Use of AI-Generated Code

The following are some of the must-do steps to ensure that the code written is used ethically and responsibly by AI models:

• Thorough testing must be performed on the generated code to capture any possible bugs or issues. This could be facilitated using automated testing frameworks.
• Make sure that a human developer can review and validate the code produced before it is included in critical parts of your project. This will work towards finding any potential mistakes or places where the model could be insecure.
• Being on top of the recent news in the field of AI-generated code to thoroughly understand their powers and possibilities. This way you can make conscious decisions about when and how to effectively use Code Llama 70B.
