Appearance
AI Settings
One place to configure AI for the whole toolkit. Every AI-powered feature — AI Bot, AI Autofill, AI Post Summary, AI Review Summary, Timeline Reply Summary, and Synonym Search — reads its provider and credentials from here.
Enable this first
The AI features show a "Please configure your AI API key in the AI Settings tab" warning and stay inert until this is set up. Configure it once and they all work.
Settings
| Setting | Description |
|---|---|
| AI Provider | WordPress AI, OpenAI, or Anthropic (Claude) |
| API Key | Your key for the selected provider. Not used by WordPress AI. |
| OpenAI Model | Used when OpenAI is the provider |
| Anthropic Model | Used when Anthropic is the provider |
| Response Language | The language AI replies in — affects AI Bot and AI Post Summary |
| Custom language | Free-text language name, used only when Response Language is set to Custom |
Providers
WordPress AI (Recommended)
Only offered on sites where WordPress's native AI client is present — WordPress 7.0 and later. Instead of storing a key in Voxel Toolkit, you configure your provider once in WordPress and every plugin shares it.
- Set AI Provider to WordPress AI (Recommended).
- Select Configure WordPress AI Connectors — this opens Settings → Connectors.
- Set up your provider and key there.
- Return and select Test Connection.
The status badge reads Connected when a provider is configured, or Not configured when none is set up yet.
No API key is stored in Voxel Toolkit
With WordPress AI selected, the toolkit holds no credentials of its own — a good reason to prefer it if you'd rather not have keys in plugin settings.
OpenAI
Enter your OpenAI API key and pick a model:
| Model | Notes |
|---|---|
| GPT-5 Mini | Recommended default — fast and inexpensive |
| GPT-5.2 | Most capable, higher cost and latency |
| GPT-5 Nano | Fastest and cheapest |
| o4-mini | Reasoning model |
Anthropic (Claude)
Enter your Anthropic API key and pick a model. Options include Claude Opus 4.7, Sonnet 4.6, Opus 4.6, Opus 4.5, Haiku 4.5, and Sonnet 4.5.
Claude Haiku 4.5 is the default — the fastest and cheapest of the set, and a sensible starting point for summaries and search.
Response language
Controls the language AI writes in, independent of your site language. Choose a listed language, or select Custom and type any language name in English — the AI will respond in it.
This affects AI Bot replies and AI Post Summary output.
Choosing a model
Cost and latency scale with capability, and these features run per post or per request:
- Summaries and search — a small, fast model is usually indistinguishable in quality. Start with GPT-5 Mini or Claude Haiku.
- Conversational AI Bot — a mid-tier model handles ambiguous questions better.
- Bulk operations — model choice matters most here. Generating summaries across a large catalogue on a top-tier model gets expensive quickly.
You can change the model at any time; it applies to the next request.
Troubleshooting
Features still say AI isn't configured
Save the settings after entering the key. The AI features check the stored value, so an unsaved key doesn't count. On WordPress AI, use Test Connection to confirm the connector responds.
"Not configured" on WordPress AI
No WordPress connector has been set up. Go to Settings → Connectors and configure a provider there — this option needs WordPress 7.0 or later.
Requests fail or time out
- Confirm the key is valid and has credit with your provider
- Confirm your server can make outbound HTTPS requests to the provider
- Try a faster model — larger models take longer and can exceed PHP timeouts on slow hosts
