Unrecognized field "audio_tokens" in chat response

[YuriMB]

[EDIT2]: Appears closely related to:
#1369

Bug description
Sometimes the openai api responds with a field audio_tokens as part of the response of OpenAiApi$Usage$CompletionTokenDetails, which is not present in the Java model. This leads to a com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException. It seems random as to when a response contains this field. The issue appears in a test, and running the test multiple times leads to different and unpredictable responses, where it sometimes is added, and sometimes is not.

Example response

{
  "id": "chatcmpl-ASOLAWmDlXXXXXXXXXXXXXX",
  "object": "chat.completion",
  "created": 1731330112,
  "model": "gpt-4o-2024-08-06",
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "<redacted>.",
        "refusal": null
      },
      "logprobs": null,
      "finish_reason": "stop"
    }
  ],
  "usage": {
    "prompt_tokens": 686,
    "completion_tokens": 14,
    "total_tokens": 700,
    "prompt_tokens_details": {
      "cached_tokens": 0,
      "audio_tokens": 0
    },
    "completion_tokens_details": {
      "reasoning_tokens": 0,
      "audio_tokens": 0,
      "accepted_prediction_tokens": 0,
      "rejected_prediction_tokens": 0
    }
  },
  "system_fingerprint": "fp_xxxxxxxxcc"
}

Environment

Java 21
SimpleVectorStore, InMemoryChatMemory,

build.gradle

    implementation platform("org.springframework.ai:spring-ai-bom:1.0.0-SNAPSHOT")
    implementation 'org.springframework.ai:spring-ai-openai-spring-boot-starter'

application.properties

spring.ai.openai.embedding.options.model=text-embedding-3-large
chatbot.model=gpt-4o-2024-05-13
chatbot.temperature=0.7
spring.jackson.deserialization.fail-on-unknown-properties=false

Steps to reproduce
Can't get it to be reproduced reliably. This is the code:

            var similarDocs = vectorStore.similaritySearch(userInput);
            response = chatClient.prompt()
                    .user(u -> u.text(userInput))
                    .system(s -> s.param("context", similarDocs))
                    .call()
                    .content();

However, the openapi specs show this field:
https://github.com/openai/openai-openapi/blob/acff98cc02da4e0ccc51cad9cef2926da7aec9be/openapi.yaml#L11443
and that field is not in the current model.

Expected behavior
I would expect that the response is parsed properly, rather than throw a com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException:.

Minimal Complete Reproducible example
n/a.

[edits]
Minor formattings, some rephrasing, and a missing SNAPSHOT tag in the build.gradle versions.
