Frontier Model Comparison
A side-by-side reference for today’s frontier large language models — context window, modalities, API pricing, open-weights status, and headline benchmarks. Many flagship models share architectural lineage — mixture-of-experts routing and chain-of-thought reasoning are now table stakes — but they diverge sharply on context length, openness, and cost.
