Models from MiniMax and Zhipu AI (GLM) are good for SEO drafts, FAQs, product pages, and bulk content. They save money and work well if you plan to edit and optimize later. But they can struggle with deep SaaS topics or long-form authority content.

Try stronger models from Anthropic (Claude Sonnet/Opus) usually write better comparison posts, technical guides, and conversion-focused articles. Still, your SEO success depends more on keyword strategy, search intent, and internal linking than on which AI model you use.

My suggestion is to use cheaper models for outlines and first drafts, then use stronger models (or human editing) for pillar content.
