LGTM!

Excuse me. My device couldn't launch llama-server when load ultravox. Here is my command:
./llama-server -m models/Llama-31-8B.gguf --mmproj models/mmproj/mmproj-ultravox-v0_5-llama-3_1.gguf -ngl 33 --port 8090

And it terminated and showed:

Any solution please?

I compiled the server myself and it started without problem although when I tried to upload a 35 minute mp3 I got this error

so I switched to this script for the server to process the ~13.2k tokens for this mp3

# /// script
# requires-python = ">=3.13"
# dependencies = [
#     "openai",
#
# ]
# ///
from base64 import b64encode
from openai import OpenAI

image_path = "shortstory034_aladdinandthemagiclamp_llf_64kb.mp3"

with open(image_path, "rb") as file:
    audio_base64 = b64encode(file.read()).decode('utf-8')

client = OpenAI(base_url="http://127.0.0.1:8080/v1", api_key="llamacpp")

completion = client.chat.completions.create(
    model="ultravox",
    messages=[
        {
            "role": "user",
            "content": [
                {"type": "text", "text": "Summarize this story."},
                {"type": "input_audio", "input_audio": {"data": audio_base64, "format": "mp3"}}
            ]
        }
    ],
    stream=True
)

for chunk in completion:
    if chunk.choices and chunk.choices[0].delta:
        content = chunk.choices[0].delta.content
        if content:
            print(content, end='', flush=True)
print()

@AeneasZhu can you try --no-mmproj-offload to see it if works? It will run the audio encoder on cpu. Also add --verbose to give more verbose log

@kth8 I'm doubt that model is trained with audio that long, but we can remove the 10MB restriction on frontend if needed

awesome - is there a way to use this to transcribe a live stream of audio or does it have to be a complete pre-made audio file?

These models are text-audio-to-text, not ASR, so I don't think they are trained or optimized for streamed real-time transcription

oh, what is the practical limit of this model? The model card didn't mention any best practices. Does it work best if I limit the audio length to ~5 mins like in your example?

I have exactly the same problem with the same GPU. I created a new issue.

@kth8 there is no clear limit for the model.

The 10MB limit is frontend-only, it's there becasue we don't want user to accidentally upload multi-gigabytes file which will crash the web page. But we can remove it anyway

@ngxson have been following you for a while from your smol-vlm release.

What does it take to support Qwen2-Audio Instruct ? it seems to have similar interface like above model. default huggingface-python is too slow for my usecase.

I wanted to understand and contribute on llama.cpp by taking this on.
any helpful set of PRs I could refer to for this ? or guidance is highly appreciate !

Just an open source lover wanting to help !!
