Large Language Models (LLMs)

Different Large Language Models (LLMs) vary by developer (OpenAI's GPT, Google's Gemini, Meta's Llama, Anthropic's Claude), capabilities (multimodal, reasoning, coding), architecture (Transformer-based), and openness (proprietary vs. open-source), with current top models like GPT-4o, Gemini 2.5, Llama 3, Claude 3.5, and Mistral offering advanced text/image understanding for diverse tasks from chatbots to complex problem-solving. 
Key LLM Families & Examples
  • OpenAI: GPT-3, GPT-4, GPT-4o (highly capable, multimodal).
  • Google: BERT, T5, Gemini (strong reasoning, multimodal).
  • Meta: Llama (Llama 2, Llama 3), known for open-source approach.
  • Anthropic: Claude (Claude 3, Claude 3.5 Sonnet), focuses on safety and nuanced dialogue.
  • Mistral AI: Mistral models (Mixtral), popular open-weight models.
  • xAI: Grok, integrated with X (Twitter) for real-time info.
  • DeepSeek: DeepSeek-R1, V3, focusing on advanced reasoning. 
Types & Architectures
Key Differentiators
  • Reasoning: Ability to solve complex, multi-step problems (DeepSeek R1, Gemini Pro).
  • Multimodality: Processing text and images (GPT-4o, Gemini).
  • Openness: Open-source (Llama, Mistral) vs. proprietary (GPT, Gemini).
  • Application: General purpose (GPT-4o), coding (Copilot), or enterprise-focused (Cohere Command).
