"""
E2E Online tests for MiniCPM-o 4.5 model with multimodal input and audio / text output.

MiniCPM-o 4.5 is a three-stage pipeline: Stage 0 Thinker (text), Stage 1 Talker
(TTS codec), Stage 2 Code2Wav (vocoder). The talker -> Code2Wav bridge supports
both async_chunk (streaming) and full-payload (``--no-async-chunk``) modes, so the
tests below exercise the sync path as well.
