AI Featured image

Yes, for at least one provider. All free-plan providers have free tiers or pay-as-you-go pricing: OpenAI, Stability AI, Grok/xAI, or Google Gemini (Pro only).

The plugin is free; you pay your provider per image:

• OpenAI: varies by model and generation quality (Low is the cheapest); see OpenAI pricing
• Stability AI: Stable Image Core is roughly ~$0.003/image; other models vary; see Stability AI pricing
• Grok/xAI: $0.02/image (Grok Imagine Image) or $0.04/image (Grok Imagine Image 2.0)
• Google Gemini (Pro): Gemini 3.1 Flash and 3 Pro vary by resolution

Yes. Select your provider and enter its API key in the plugin settings. The page shows only the options relevant to your selection. Free users can switch between OpenAI, Stability AI, and Grok/xAI; Pro adds Google Gemini.

Only your API plan’s quota with your chosen provider. The plugin generates one image per request.

OpenAI (Free & Pro): GPT Image 2 (default, with strong text rendering and visual reasoning). Pro adds GPT Image 2.5 Flare (up to 50% faster than GPT Image 2 with sharper detail) and GPT Image 2.5 Sunburst (the most detailed), both with Extra High and Max generation quality.

Stability AI: Stable Image Core (free): fast, high quality, best value. Pro adds Stable Image Ultra (best quality), SD 3.5 Large / Large Turbo / Medium / Flash, SD 3 Large / Large Turbo / Medium, and SDXL 1.0 (legacy).

Grok / xAI: Grok Imagine Image (free, $0.02/image) and Grok Imagine Image 2.0 (Pro, $0.04/image).

Google Gemini (Pro only): Gemini 3.1 Flash Image (1K/2K/4K) and Gemini 3 Pro Image (best quality, 1K/2K/4K). Both support 10 aspect ratios.

21 built-in styles that work with all providers: None, Realistic, Artistic, Cartoon, Minimalist, Sketch, Watercolor, 3D Render, Pixel Art, Cyberpunk, Fantasy, Anime, and Technicolor, plus the Trending group: Toy Figure, Miniature World, Claymation, Cinematic, Lo-Fi Cozy, Vintage Instant Photo, Magazine Collage, and Paper Cut.

With Stability AI you also get a Stability Presets group of 16 native API-level presets: Photographic, Cinematic, Anime, Digital Art, Comic Book, Fantasy Art, 3D Model, Analog Film, Enhance, Isometric, Line Art, Low Poly, Neon Punk, Origami, Pixel Art, and Tile Texture.

Pro users can also create unlimited custom styles (see below).

Yes. Go to AI Images → Settings → Brand & Styles → Custom Styles, click “Add Style”, and enter a name plus a prompt description (e.g. “in a dreamy impressionist style”). Custom styles appear in all style dropdowns and work exactly like built-in styles.

One global set of brand rules that keeps every AI image on-brand. Go to AI Images → Settings → Brand & Styles and save up to 3 brand colors, a style description, a tone, and avoid-rules; optionally add a reference image (used by Google Gemini to match your visual style) and a logo watermark with position, size, opacity, and margin controls. The kit is applied automatically wherever you generate: post editor, Bulk Generate, the Posts list, and the AI Image Generator block. The post editor, Bulk Generate, and the block each have a “Use Brand Kit” checkbox you can uncheck for a one-off image; the Posts list always applies the kit.

• OpenAI: 7 sizes with GPT Image 2 and 2.5: 1024×1024 (1:1), 1024×1536 (portrait), 1536×1024 (landscape), 1792×1024 (16:9), 1024×1792 (9:16), 1920×640 (3:1), and 640×1920 (1:3)
• Stability AI: 1:1, 16:9, and 9:16 free; Pro unlocks all 9 (adds 21:9, 2:3, 3:2, 4:5, 5:4, 9:21)
• Grok: 1:1, 16:9, and 9:16 free; Pro unlocks all 9 (adds 4:3, 3:4, 3:2, 2:3, 2:1, 1:2)
• Gemini (Pro): 10 ratios (1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9): 1K/2K/4K on Gemini 3.1 Flash and 3 Pro

Yes, with a Stability AI API key. Once a featured image is set, a “Stability AI Tools” panel appears in the post editor with three modes: Conservative (faithful 4x), Creative (AI-enhanced 4K), and Fast (quick 4x). Conservative and Creative process asynchronously and may take up to ~3 minutes; the result automatically becomes your new featured image.

Yes, from the same “Stability AI Tools” panel. Click “Remove Background” and Stability AI isolates the subject and saves a transparent PNG as your featured image, which suits product shots and portraits.

Text that tells Stability AI what not to include, e.g. “blurry, watermark, text, low quality”. Set defaults in AI Images → Settings → Featured Images (and the Inline Images tab). Negative prompts have no effect with OpenAI, Gemini, or Grok.

• OpenAI: WebP (recommended), PNG, or JPEG
• Stability AI: PNG free; Pro adds JPEG and WebP
• Grok: JPEG free; Pro adds WebP (converted after generation)
• Gemini (Pro): PNG default, or WebP (converted after generation)

Because the Gemini and Grok APIs return PNG/JPEG, the plugin converts to WebP using your server’s image library (ImageMagick or GD).

WebP conversion for Gemini and Grok needs a WebP-capable image library on your server (GD with WebP, or ImageMagick with the WebP delegate). If it’s missing, the plugin safely falls back to the provider’s native format and shows a notice with the reason. Generation never fails. Ask your host to enable WebP if needed. OpenAI WebP is unaffected because the API returns it directly.

• OpenAI: Output Compression slider (1–100, default 90) plus a Low/Medium/High generation quality tier (Extra High and Max on GPT Image 2.5, Pro)
• Stability AI: quality is inherent to the model you choose
• Grok: 1K resolution free; Pro can choose 2K
• Gemini (Pro): 1K/2K/4K on 3.1 Flash and 3 Pro
• Inline images (all providers): Automatic Quality Optimization picks quality and resolution based on the image’s display size in your content

Yes. Add the “AI Image Generator” block from the Media category, enter a prompt, and generate images anywhere in your content. The block supports the same providers, styles, and aspect ratios as featured images; configure defaults in the Inline Images settings tab.

Every AI image (featured, inline, or bulk) automatically gets alt text in the media library. Configure it under AI Images → Settings → General → Alt Text: choose the post title (default), the generation prompt, or a custom template with {title}, {prompt}, {style}, and {site_name} placeholders. e.g. {title} - {style} style - {site_name}. By default, manually edited alt text is preserved on regeneration; enable “Overwrite on Regeneration” to always refresh it.

Click “Generate Prompt from Content” in the post editor and AI writes an image prompt from your post title and body. It’s saved to the post and pre-filled in the Custom Prompt field so you can review or edit before generating. The same option exists in Bulk Generate, creating a unique prompt per post.

Text model per provider: gpt-4o-mini (OpenAI), grok-4.3 (Grok), Gemini 3.6 Flash (Gemini, Pro). Stability AI has no text API, so the button shows a notice when it’s the active provider.

Yes. Go to AI Images → Settings → General → Availability, check the post types you want, and save. The generator panel then appears in the editor for those post types. Free users are limited to Posts and Pages.
