SEO & Chill connects to ten AI providers: OpenAI, Anthropic Claude, Google Gemini, DeepSeek, Mistral AI, Groq, xAI Grok, OpenRouter, Moonshot Kimi and Custom: any OpenAI-compatible service on a public HTTPS address. You bring your own API key and can switch anytime. That freedom raises an obvious question: which one should you pick?
What SEO work actually asks of a model
Most SEO tasks are short, structured and high-volume: a meta description here, forty product titles there, an outline, a set of anchor-text suggestions. That profile is different from long-form writing. It rewards models that follow instructions tightly and return consistent formats. And it makes speed and cost per request matter more than raw benchmark scores.
A practical way to decide
Bulk work. Meta tags, alt text, product fields. This is where volume lives, so cost and speed dominate. Fast, inexpensive models from any major provider handle meta generation well; many of our users run bulk jobs on Groq or DeepSeek precisely because the per-request price barely registers.
Outlines and content advice. Here reasoning quality shows. Claude and the larger OpenAI and Gemini models tend to produce outlines that need fewer edits. Better section logic, fewer invented subtopics. Since outlines are low-volume, paying a little more per request costs almost nothing in practice.
Privacy-sensitive sites. If your content cannot go to an outside vendor, run a model on your own server and connect it as Custom, on a public HTTPS address; the plugin refuses localhost and private network addresses on purpose. You trade some output quality and setup time for complete data control. For many internal or regulated sites that trade is correct.
Not sure yet? OpenRouter gives you one key that reaches many models, which makes it a low-friction way to experiment before you commit.
The answer most people land on
Two providers: a cheap, fast one for bulk operations and a stronger one for outlines and advice. Because switching is a dropdown in SEO & Chill. Not a migration. You can revisit the choice whenever pricing or models change. That is the point of not being locked in.
