/*
|
|
* ITFlow - Admin > AI Providers (admin/ai_providers.php): adding one,
|
|
* changing it, testing it and deleting it.
|
|
*
|
|
* Saving checks what was sent (aiProviderCheck(), functions/ai.php) and, when
|
|
* its kind, address or key is new or changed, asks the provider for its models
|
|
* - which says whether they work. The window asks first (check_ai_provider,
|
|
* which answers in JSON) and says what is wrong beside each field; a provider
|
|
* that doesn't answer right now can still be saved once the window has said
|
|
* so (save_anyway). Adding one can add its first model too. What changed is in
|
|
* the audit log, from what to what - the key only as changed.
