Because SEO Content Architect is a BYOK (bring-your-own-key) app, you don’t buy a fixed “quality tier” — you dial cost against quality yourself, per article, by choosing which text and image models run the job. The same pipeline can produce an article for a few cents or for $1–2, and the difference is entirely which models you point it at. This guide gives you three ready-made setups — Budget, Balanced, and Premium — so you can match every article to what it’s actually worth.

If you write content with AI, model choice matters more than most prompt tweaks. The three major families — Google Gemini, OpenAI GPT, and Anthropic Claude — each have distinct strengths for long-form SEO writing, and the “best” one depends on your niche, language, budget, and volume. This comparison is based on generating thousands of articles across all three (plus the OpenRouter long tail), and ends with concrete recommendations per use case.
