18 Leading Large Language Models (LLMs) in 2024

Introduction to Large Language Models

Large Language Models (LLMs) are at the forefront of the rapid advancements in generative AI. While relatively new in their current form, their development builds upon decades of research. LLMs are complex AI systems that process and generate human-like text using deep learning on massive datasets.

Key milestones include the introduction of the attention mechanism (2014) and the transformer model (2017), which significantly improved LLMs' ability to handle long-range dependencies in text. ChatGPT's remarkable popularity highlighted the potential of LLMs and spurred the development of numerous other models.

Top Current LLMs: A Diverse Landscape

The field of LLMs is dynamic, with many models constantly being improved and new ones emerging. This list showcases some prominent models, categorized for clarity:

Proprietary Models (Developed and Owned by Companies)

  • BERT (Google, 2018): A transformer-based model used for various natural language tasks, notably improving Google Search's understanding of queries.
  • Claude (Anthropic): Emphasizes "constitutional AI," aligning outputs with safety and helpfulness principles. Known for its latest version, Claude 3.0.
  • Gemini (Google): A multimodal model processing text, images, audio, and video. It powers Google's Gemini chatbot and is integrated into many Google products. Offered in Ultra, Pro, and Nano versions.
  • GPT-3 (OpenAI, 2020): A large model (over 175 billion parameters) using a decoder-only transformer architecture. Previously exclusively licensed to Microsoft.
  • GPT-3.5 (OpenAI): An enhanced version of GPT-3, fine-tuned with human feedback. Powers ChatGPT.
  • GPT-4 (OpenAI, 2023): OpenAI's most advanced model, also multimodal, known for its performance on academic tests and integration into Microsoft products.
  • LaMDA (Google Brain, 2021): A dialogue-focused language model, notable for its conversational abilities.
  • Palm (Google): A large (540 billion parameter) model powering Google's Bard chatbot, excelling in complex reasoning tasks.

Open-Source Models (Publicly Available)

  • Cohere: Provides several customizable LLMs for businesses, not limited to a specific cloud provider.
  • Ernie (Baidu): Underpins Baidu's Ernie 4.0 chatbot, showing particular strength in Mandarin Chinese.
  • Falcon 40B (Technology Innovation Institute): A powerful transformer-based model available on GitHub and Amazon SageMaker.
  • Gemma (Google): Open-source models, trained similarly to Gemini, known for their efficiency and ability to run locally.
  • Llama (Meta AI, 2023): Highly influential open-source model available in different sizes, known for its efficiency and open access. Has been a basis for many other models.
  • Mistral (Mistral AI): A 7-billion parameter model outperforming similarly sized Llama models on various benchmarks.
  • Orca (Microsoft): A relatively smaller model (13 billion parameters) designed to mimic the reasoning capabilities of larger models.
  • Phi-1 (Microsoft): A smaller model trained on high-quality data, showcasing a trend towards more efficient models.
  • StableLM (Stability AI): Open-source models offered in various sizes, emphasizing openness and helpfulness.
  • Vicuna 33B (LMSYS): A model based on Llama, fine-tuned using data from shareGPT.com, demonstrating strong performance for its size.

LLM Precursors

While modern LLMs are relatively recent, their development builds upon earlier work:

  • ELIZA (1966): One of the earliest natural language processing programs, using pattern matching to simulate conversation.
  • Seq2Seq (Google): A deep learning technique used for machine translation and other NLP tasks, forming the basis for several current LLMs.

How Large Language Models Work

LLMs learn by processing massive amounts of text data (books, articles, web data). They use a transformer architecture with an attention mechanism to understand relationships between words and generate coherent text. The training process involves:

  • Pre-training: Unsupervised learning on large text corpora to learn language patterns, facts, and some reasoning.
  • Fine-tuning: Supervised learning on specific tasks (e.g., translation, summarization) to improve performance.

Though they generate impressive text, LLMs don't truly "understand" meaning; their output is based on patterns identified in the training data.
