Leading LLMs: A Comparison Guide

OpenAI's GPT-4 offers strong performance across reasoning, coding, and multimodal understanding with a robust API ecosystem, though at higher per-token cost. Anthropic's Claude emphasizes safety, helpfulness, and long-context processing with large context windows up to 200K tokens. Google's Gemini leverages strong multimodal capabilities and Google Cloud integration.

Open-source models like Meta's Llama and Mistral offer deployment flexibility and data privacy, with performance sufficient for many production applications especially after domain-specific fine-tuning. For data-sensitive or high-volume use cases, open-source models often provide the best total cost of ownership.
