Key GenAI skills every dev should know#

Every developer should be familiar with a few key GenAI concepts that every developer should be familiar with. Understanding these concepts will provide a solid foundation for any software engineer hoping to stay competitive in the modern tech landscape.

• Python programming: Python is essential as the primary language for AI development. It’s widely used for its simplicity and extensive libraries that support AI, machine learning, deep learning, and Generative AI.

• Machine learning basics: Understanding core machine learning concepts, including supervised and unsupervised learning, is fundamental. Familiarize yourself with algorithms and their applications.

• Neural networks and deep learning: Learn how neural networks function and how to build deep learning models. Tools like TensorFlow and PyTorch are invaluable for this purpose.

• Natural language processing (NLP): NLP is crucial for text and language tasks. Skills in NLP will enable you to develop applications that understand and generate human language.

• Generative models: Dive into generative models, including generative adversarial networks (GANs), variational autoencoders (VAEs), transformers, and diffusion models. They are essential for creating new data from existing data and have applications in art, music, and content creation.

• Large language models (LLMs): Understand the different types, capabilities, and evaluation metrics of LLMs. Learn how to fine-tune models like GPT-3 and GPT-4 for specific tasks, improving their performance for your unique needs. These models are trained on massive amounts of textual data and have amazing capabilities like language generation and understanding, machine translation,  conversational capabilities, code, video, image, speech generation, and knowledge answering. Some examples of LLMs include the GPT series, Gemini, Llama, Mistral, Ollama, Vicuna, Olmo, and Phi-2. 

• Prompt engineering:  Learn the art of designing and refining prompts to optimize the output of language models. The input query that is fed to LLM is called a prompt. ​Prompting provides an initial text input to guide the model in generating a relevant and coherent response. Effective prompt engineering can significantly improve the accuracy and relevance of AI-generated responses.

• Vector databases: Master vector databases, which are crucial for handling high-dimensional data in GenAI applications. These databases enable efficient storage and retrieval of vectors, essential for similarity searches and clustering. It is a database that stores different types of data, such as text, images, audio, and video, in a numerical form referred to as a vector. Some examples include Faiss, Chromadb, and pinecone. Master any one of them to upskill your generative AI career.

• Retrieval-Augmented Generation (RAG): Explore RAG techniques that combine the power of retrieval systems with generative models. As LLMs are not trained on our customized datasets, RAG helps add that data to the LLMs. This helps in producing accurate and contextually relevant responses. RAG works by taking an input query, retrieving relevant information from a large corpus, and using this information to generate a contextually relevant response. 

• LangChain: Learn about LangChain—sequences of language models working together. Understanding how to implement and optimize LangChain can significantly boost the performance of your AI applications. LangChain is an open-source framework available in Python and JavaScript that simplifies the integration of large language models (LLMs) for developing LLM-powered applications.

Another product launched by the same developers as LangChain is LangSmith. This comprehensive developer platform is designed for every LLM-powered application life cycle stage, whether or not you’re using LangChain. It enables you to debug, collaborate, test, and monitor your LLM applications effectively. LangGraph (another product of the same org) is a library for building stateful, multi-actor applications with LLMs designed to create agent and multi-agent workflows.

• Agentic systems: Study agentic systems, where AI agents interact with each other and the environment. These systems are vital for developing autonomous AI solutions to perform complex tasks with minimal human intervention. Agentic systems refer to models and frameworks that exhibit autonomous decision-making capabilities, allowing them to perform complex tasks without continuous human guidance. 

• Ollama: Familiarize yourself with Ollama. Wondering how to run an LLM on your local machine? Concerned about memory, GPUs, and other requirements? Enter Ollama: a user-friendly, open-source platform that simplifies running LLMs. Think of it as a Docker file pre-loaded with LLM weights and settings. Ollama supports a range of models like the Llama series, Phi family, Mistral, and Gemma 2 and integrates with LangChains for enhanced functionality.

Fun fact: By 2030, it’s expected that over 30% of new software code will be written or assisted by AI, drastically speeding up development cycles and opening new possibilities for innovation.

Which GenAI skills will help developers get ahead in the industry?#

Now, let’s explore what the industry demands from developers in varying AI engineering specializations—from entry-level positions to senior roles.

To begin with, it’s crucial to have a solid grasp of Generative AI and stay updated on the latest trends in the field. You should understand how LLMs are trained, how to craft effective prompts, and how RAG and vector databases are utilized. Proficiency in using LangChain is also important.

Additionally, some positions may require experience with tools like Hugging Face, AutoGPT, and AgentGPT. Certain companies also look for expertise in developing interfaces for systems that facilitate the use of their local LLMs.

As we move up the hierarchy, firms require extensive experience in AI/ML/DL algorithms and hands-on expertise in fine-tuning LLMs on customized datasets. Candidates should be adept at selecting the appropriate vector database to meet company needs. Experience with Generative AI and LLM-based solutions and proficiency in evaluating LLM is often essential. A lead Generative AI engineer should be capable of fine-tuning LLMs from scratch and explaining technical terms to non-technical stakeholders. Additionally, many companies value experience with diffusion models and transformers.
