The OpenAI API's embedding endpoint can lead to silent failures due to inconsistencies in vector dimensions and encoding formats. Unlike chat completions, embedding errors do not throw exceptions, making retrieval quality degradation appear as a prompt or chunking issue. To prevent this, developers should implement contract tests that explicitly check for vector shape, dimension length, and encoding format (float vs. Base64), as the default behavior of the Python SDK can differ from API documentation.
