As mentioned in the issue #3786 , when using embedding models, we need to support the
encodingFormat=base64
parameter. When this format is used, the model returns theembedding
field as a base64-encoded string representing a float array. This PR adds support for handling that format.Changes in this PR:
OpenAiEmbeddingDeserializer
, for theembedding
field inorg.springframework.ai.openai.api.OpenAiApi.Embedding
. This deserializer automatically converts the base64-encoded string back into a float array when parsing the API response.Fixes: #3786
