What are "frontier models"?

Question

Accepted Answer

Frontier models are the latest and most capable AI models from leading AI providers — the flagship, state-of-the-art tier from each vendor, such as OpenAI's GPT-5, Anthropic's Claude Opus 4.6, Google's Gemini Ultra, and Meta's Llama 4. They represent the highest current level of reasoning, code generation, and multimodal understanding, and are usually the most expensive per-token models each provider offers. Frontier models are the reference point when comparing what's technically possible today. For most day-to-day workloads (summarization, chat, routine code), smaller and cheaper models from the same providers often deliver 80–90% of the quality at a fraction of the cost — which is why the AI Calculator lets you compare frontier vs. non-frontier models side by side.
