// Self-hosted embeddings — like openaiCompatNode, but the baseUrl is REQUIRED.
|
||
|
|
//
|
||
|
|
// openaiCompatNode falls back to https://api.openai.com/v1 when a connection
|
||
|
|
// carries no providerSpecificData.baseUrl. For a custom NODE that default is
|
||
|
|
// defensible: the node was created by pointing at some OpenAI-compatible URL, and
|
||
|
|
// OpenAI is the archetype. For a provider whose entire purpose is "my own
|
||
|
|
// server", it is actively harmful — a connection saved without a baseUrl sends
|
||
|
|
// the INPUT TEXT and the API KEY to OpenAI, silently, under a provider named
|
||
|
|
// "Self-hosted Embedding".
|
||
|
|
//
|
||
|
|
// Observed exactly that with a placeholder connection (2026-08-04):
|
||
|
|
//
|
||
|
|
// [selfhosted-embedding/embedding] [401]: Incorrect API key provided: abc.
|
||
|
|
// You can find your API key at https://platform.openai.com/account/api-keys.
|
||
|
|
//
|
||
|
|
// The key "abc" was typed as a throwaway for a LOCAL server and left the network.
|
||
|
|
// A self-hosted provider must never have a cloud fallback, so this one refuses
|
||
|
|
// instead: no baseUrl means a configuration error, reported as such.
