You can write with a model included with your plan, or connect a supported provider account. In Settings → Integrations, the direct writing connections under Other AI providers are:
OpenAI: GPT writing models.
Claude (Anthropic): Claude writing models, such as Sonnet, Haiku, or Opus when offered.
Gemini (Google): Gemini writing models, including Flash or Pro options when offered.
DeepSeek: DeepSeek chat and reasoning models.
MiniMax: MiniMax M-series writing models.
Kimi (Moonshot AI): Kimi writing models.
OpenRouter is a separate option. It lets you use one OpenRouter account for writing models from multiple companies. Depending on the current list, examples include Qwen, Grok, Llama, Mistral, Claude, and Gemini. A direct subscription or key with another provider is not an OpenRouter key.
To see the exact model versions your team can use, a Blog Site owner or admin can open the connected provider’s card. Writing model and billing → Included with your plan lists the current options that work without your key. In the editor, writers see the models available to them for that action. Provider setup guide.
