Groq Fast LLM Inference Integration

Groq Integration for Fast LLM Inference

Groq uses its own LPU (Language Processing Unit) — a specialized processor for language model inference. Result: 500–800 tokens/sec vs 50–100 at GPU providers. This opens scenarios that were previously impossible: real-time transcription with instant answers, interactive coding assistants without noticeable delays.

Basic Integration

from groq import Groq, AsyncGroq

client = Groq(api_key="GROQ_API_KEY")
async_client = AsyncGroq(api_key="GROQ_API_KEY")

# Synchronous request — noticeably faster than other providers
response = client.chat.completions.create(
    model="llama-3.1-70b-versatile",
    messages=[{"role": "user", "content": "Explain the concept"}],
    temperature=0,
    max_tokens=1024,
)
print(response.choices[0].message.content)

# Async
async def fast_query(prompt: str) -> str:
    response = await async_client.chat.completions.create(
        model="llama-3.1-8b-instant",  # Extremely fast
        messages=[{"role": "user", "content": prompt}],
    )
    return response.choices[0].message.content

# Streaming (low latency to first token)
def stream_fast(prompt: str):
    with client.chat.completions.stream(
        model="llama-3.1-70b-versatile",
        messages=[{"role": "user", "content": prompt}],
    ) as stream:
        for text in stream.text_stream:
            yield text

Audio Transcription (Whisper on Groq)

# Whisper on Groq — fastest transcription in the cloud
with open("audio.mp3", "rb") as audio_file:
    transcription = client.audio.transcriptions.create(
        file=("audio.mp3", audio_file.read()),
        model="whisper-large-v3",
        language="ru",
        response_format="verbose_json",  # With timestamps
    )
print(transcription.text)

# Translation
translation = client.audio.translations.create(
    file=("audio.mp3", open("audio.mp3", "rb").read()),
    model="whisper-large-v3",
)

Available Models Groq

When Groq is Right Choice

Groq optimal for:

• Chatbot requiring < 500 ms to first token
• Realtime code completion (IDE assistant)
• Batch processing with tight SLAs
• Audio transcription in real-time

Groq not suitable for:

• Tasks with very large output (cost higher for long answers)
• When maximum accuracy matters (Llama 70B < Claude Opus/GPT-4o)
• Cost at high loads
