PerplexityBot

Unsupervised Learning
Training a model on unlabelled data and letting it find structure by itself — grouping similar customers, say, without being told what the groups are.
Applebot-Extended
Apple’s equivalent, governing whether your content feeds Apple Intelligence. Ordinary Applebot, which powers Siri and Spotlight, is controlled separately.
Entity SEO
Optimising to be recognised as a specific, real thing rather than for particular keywords. In practice it means consistent naming, structured data, and being mentioned in enough other places to be corroborated.
Fine-Tuning
Taking a general model and training it further on your own examples so it follows your tone or handles your particular task. Useful when prompting alone keeps producing nearly-right answers.
OAI-SearchBot
The crawler OpenAI uses to answer live searches in ChatGPT, separate from GPTBot. Blocking one does not block the other, so a site can be absent from ChatGPT search while still being read for training.
Speech Recognition
Turning spoken words into text. It underpins voice search, dictation and call transcription, and it now handles accents and background noise far better than it used to.
