# AI Frontier Model The most capable AI models at any given time, representing the cutting edge of performance across benchmarks and real-world tasks. The term "frontier" distinguishes these from the broader category of foundation models: all frontier models are foundation models, but not all foundation models are frontier. Current frontier models (as of early 2026): Claude (Anthropic), GPT-4/o1/o3 (OpenAI), Gemini (Google), Grok (xAI). Frontier models attract the most regulatory attention because their capabilities create novel risks. The concept is inherently temporal; today's frontier is tomorrow's baseline. ## References ## Related - [[Large Language Models (LLMs)]] - [[AI Safety]] - [[AI Governance]] - [[AI Foundation Models]] - [[AI Scaling Laws]] - [[AI Alignment]]
