 Code example: <gh-file:examples/online_serving/openai_transcription_client.py>
-<!-- TODO: api enforced limits + uploading audios -->
 
 #### API Enforced Limits
 
 Set the maximum audio file size (in MB) that VLLM will accept, via the
 `VLLM_MAX_AUDIO_CLIP_FILESIZE_MB` environment variable. Default is 25 MB.
 
+#### Uploading Audio Files
+
+The Transcriptions API supports uploading audio files in various formats including FLAC, MP3, MP4, MPEG, MPGA, M4A, OGG, WAV, and WEBM.
+
+**Using OpenAI Python Client:**
+
+??? code
+
+    ```python
+    from openai import OpenAI
+
+    client = OpenAI(
+        base_url="http://localhost:8000/v1",
+        api_key="token-abc123",
+    )
+
+    # Upload audio file from disk
+    with open("audio.mp3", "rb") as audio_file:
+        transcription = client.audio.transcriptions.create(
+            model="openai/whisper-large-v3-turbo",
+            file=audio_file,
+            language="en",
+            response_format="verbose_json"
+        )
+
+    print(transcription.text)

+    curl -X POST "http://localhost:8000/v1/audio/transcriptions" \
+      -H "Authorization: Bearer token-abc123" \
+      -F "file=@audio.mp3" \
+      -F "model=openai/whisper-large-v3-turbo" \
+      -F "language=en" \
+      -F "response_format=verbose_json"
