Evolution of LLMs

Large Language Models (LLMs) have revolutionized the way computers understand and generate language. These models started small but have grown in scale and capability, solving increasingly complex problems over time. Let’s break this journey into manageable chunks, exploring the different types of LLMs, their milestones, and the latest advancements.

Categories of LLMs

LLMs come in different flavors, each tailored to a specific purpose or application.

• General-Purpose Models: These versatile models can handle a wide range of tasks, from writing essays to solving coding problems. Prominent examples include OpenAI’s GPT-4, known for its contextual understanding, and Anthropic’s Claude 3.5 Sonnet, which excels in conversational tasks.

• Domain-Specific Models: These specialized models focus on particular industries or tasks. OpenAI’s Codex, optimized for programming, and BioGPT, tailored for medical research, are notable examples. Such models provide highly precise and context-aware responses for their respective fields.

• Open-Source Models: Open-source initiatives democratize AI by making advanced capabilities accessible to everyone. Meta’s Llama models, BigScience’s BLOOM, and NVIDIA’s NVLM 1.0 are key contributors. These projects empower developers and researchers globally with high-performance tools.

• Small Language Models (SLMs): Compact yet efficient, SLMs excel at specific tasks like sentiment analysis or real-time translation while consuming fewer computational resources. Examples include T5-Small, DistilBERT, and Phi-2 by Microsoft, designed for lightweight and domain-specific applications.

• Multimodal Models: This groundbreaking category integrates text with images, audio, or video. OpenAI’s DALL-E and Google’s Gemini 2.0 are prime examples, enabling creative and analytical tasks requiring diverse data types. Additionally, text-to-image models like MidJourney, StableDiffusion, and Recraft have expanded possibilities for content creation, while text-to-video models like Sora represent the next frontier in multimodal AI.
