runcrate-sdk 0.1.0

Official Python SDK for the Runcrate API

Runcrate Python SDK

Official Python SDK for the Runcrate API.

Installation

pip install runcrate

Quick Start

from runcrate import Runcrate

client = Runcrate(api_key="rc_live_...")

# Chat completion
response = client.models.chat_completion(
    model="meta-llama/Meta-Llama-3.1-8B-Instruct",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)

# List GPU instances
instances = client.instances.list()

# Create an instance
instance = client.instances.create(
    name="training-run",
    ssh_key_id="key_abc123",
    gpu_type="A100",
)

# Check status
status = client.instances.get_status(instance.id)
print(status.status, status.ip)

# Check billing
balance = client.billing.get_balance()
print(f"Credits: ${balance.credits_balance}")

client.close()

Async Usage

import asyncio
from runcrate import AsyncRuncrate

async def main():
    async with AsyncRuncrate(api_key="rc_live_...") as client:
        response = await client.models.chat_completion(
            model="meta-llama/Meta-Llama-3.1-8B-Instruct",
            messages=[{"role": "user", "content": "Hello!"}],
        )
        print(response.choices[0].message.content)

asyncio.run(main())

Configuration

client = Runcrate(
    api_key="rc_live_...",                        # or set RUNCRATE_API_KEY env var
    base_url="https://runcrate.ai",               # infra API (default)
    inference_url="https://api.runcrate.ai",      # model inference API (default)
    timeout=30.0,                                 # request timeout in seconds
    max_retries=3,                                # retry on 429/5xx with exponential backoff
)

Model Inference

The client.models resource connects to api.runcrate.ai for AI model inference. Same API key works for both infrastructure and inference.

Chat Completions

# Standard request
response = client.models.chat_completion(
    model="meta-llama/Meta-Llama-3.1-8B-Instruct",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Explain quantum computing in 3 sentences."},
    ],
    max_tokens=256,
    temperature=0.7,
)
print(response.choices[0].message.content)
print(f"Tokens used: {response.usage.total_tokens}")

# Streaming
for chunk in client.models.chat_completion(
    model="meta-llama/Meta-Llama-3.1-8B-Instruct",
    messages=[{"role": "user", "content": "Write a poem about GPUs"}],
    stream=True,
):
    delta = chunk.get("choices", [{}])[0].get("delta", {})
    print(delta.get("content", ""), end="", flush=True)

Image Generation

result = client.models.generate_image(
    model="black-forest-labs/FLUX.1-schnell",
    prompt="A futuristic city skyline at sunset",
    width=1024,
    height=1024,
)
# result.data[0].b64_json contains the base64-encoded image

Video Generation

# Submit video job (async processing)
job = client.models.generate_video(
    model="google/veo-3.0",
    prompt="A drone flyover of a mountain landscape",
    duration=8,
)
print(f"Job ID: {job.id}, Status: {job.status}")

# Poll until complete
import time
while True:
    job = client.models.get_video_status(job.id)
    print(f"Status: {job.status}")
    if job.status in ("completed", "failed"):
        break
    time.sleep(5)

# Download the video
if job.status == "completed":
    video_bytes = client.models.download_video(job.id)
    with open("output.mp4", "wb") as f:
        f.write(video_bytes)

Text-to-Speech

audio_bytes = client.models.text_to_speech(
    model="openai/tts-1",
    input="Hello, welcome to Runcrate!",
    voice="alloy",
    response_format="mp3",
)
with open("speech.mp3", "wb") as f:
    f.write(audio_bytes)

Transcription (Speech-to-Text)

with open("audio.wav", "rb") as f:
    result = client.models.transcribe(
        model="openai/whisper-1",
        file=f,
        filename="audio.wav",
    )
print(result.text)
print(f"Duration: {result.duration}s")
