Background
The 2026 AI model landscape: OpenAI's GPT series leads in general capability, Anthropic's Claude excels in safety and long-form, Google's Gemini features multimodal and ultra-long context, Meta's Llama is the open-source benchmark, and DeepSeek has rapidly emerged with ultra-low pricing and open-source strategy. When choosing a model, consider: task type (code/text/multimodal), context needs, budget, latency requirements, and data privacy (local deployment needs).
