For two years, AI buyers asked “which model is best?” In late 2025, the honest answer became: it depends what you are doing. The three frontier providers have specialised. There is no longer one winner.
OpenAI dominates voice and multi-modal. Anthropic dominates code and agentic tool use. Google dominates long-context, price, and Workspace integration. Each genuinely wins their category. The smartest businesses route different workloads to different providers and beat single-vendor deployments on every metric - cost, quality, reliability.
This page is the honest comparison. We tell you what each wins, what each loses, and how to think about a multi-model strategy.
