Mistral-Common can now process streaming requests

import numpy as np
from mistral_common.audio import Audio
from mistral_common.protocol.instruct.chunk import RawAudio
from mistral_common.protocol.transcription.request import StreamingMode, TranscriptionRequest
from mistral_common.tokens.tokenizers.mistral import MistralTokenizer

# 1. Load the tokenizer with audio support
tokenizer = MistralTokenizer.from_hf_hub("mistralai/Voxtral-Mini-4B-Realtime-2602")
# 2. Create sample audio data (or load from a file)
sampling_rate = 16_000
duration_s = 2.0
audio_array = np.random.uniform(-1, 1, size=int(duration_s * sampling_rate)).astype(np.float32)
audio = Audio(audio_array=audio_array, sampling_rate=sampling_rate, format="wav")
# 3. Create the streaming transcription request
request = TranscriptionRequest(
    audio=RawAudio(data=audio.to_base64("wav"), format="wav"),
    streaming=StreamingMode.ONLINE,  # or StreamingMode.OFFLINE
    language=None,
)
# 4. Encode the request
tokenized = tokenizer.encode_transcription(request)
# 5. Access the results
print(f"Tokens: {tokenized.tokens}")
print(f"Number of tokens: {len(tokenized.tokens)}")
print(f"Number of audio segments: {len(tokenized.audios)}")

Raw content

Add AudioURLChunk by @juliendenize in #120

Now you can use http(s) URLs, file paths and base64 string (without specifying format) in your content chunks thanks to AudioURLChunk !

from mistral_common.protocol.instruct.request import ChatCompletionRequest
from mistral_common.tokens.tokenizers.mistral import MistralTokenizer

repo_id = "mistralai/Voxtral-Mini-3B-2507"
tokenizer = MistralTokenizer.from_hf_hub(repo_id)

text_chunk = TextChunk(text="Wat do you think about this audio?")
user_msg = UserMessage(content=[AudioURLChunk(audio_url=AudioURL(url="https://freewavesamples.com/files/Ouch-6.wav")), text_chunk])
request = ChatCompletionRequest(messages=[user_msg])
tokenized = tokenizer.encode_chat_completion(request)
# pass tokenized.tokens to your favorite audio model
print(tokenized.tokens)
print(tokenized.audios)
# print text to visually see tokens
print(tokenized.text)
