Spin up isolated containers to run LLM-generated code:
from beam import Image, Sandbox
sandbox = Sandbox(image=Image()).create()
response = sandbox.process.run_code("print('I am running remotely')")
print(response.result)
Create an autoscaling endpoint for your custom model:
from beam import Image, endpoint
from beam import QueueDepthAutoscaler
@endpoint(
image=Image(python_version="python3.11"),
gpu="A10G",
cpu=2,
memory="16Gi",
autoscaler=QueueDepthAutoscaler(max_containers=5, tasks_per_container=30)
)
def handler():
return {"label": "cat", "confidence": 0.97}
Schedule resilient background tasks (or replace your Celery queue) by adding a simple decorator:
from beam import Image, TaskPolicy, schema, task_queue
class Input(schema.Schema):
image_url = schema.String()
@task_queue(
name="image-processor",
image=Image(python_version="python3.11"),
cpu=1,
memory=1024,
inputs=Input,
task_policy=TaskPolicy(max_retries=3),
)
def my_background_task(input: Input, *, context):
image_url = input.image_url
print(f"Processing image: {image_url}")
return {"image_url": image_url}
if __name__ == "__main__":
# Invoke a background task from your app (without deploying it)
my_background_task.put(image_url="https://example.com/image.jpg")
# You can also deploy this behind a versioned endpoint with:
# beam deploy app.py:my_background_task --name image-processor
