cortecs-py

Lightweight wrapper for the cortecs.ai enabling instant provisioning.

⚡Quickstart

Dynamic provisioning allows you to run LLM-workflows on dedicated compute. The LLM and underlying resources are automatically provisioned for the duration of use, providing maximum cost-efficiency. Once the workflow is complete, the infrastructure is automatically shut down.

This library starts and stops your resources. The logic can be implemented using popular frameworks such as LangChain or crewAI.

1. Start your LLM
2. Execute (massive batch) jobs
3. Shutdown your LLM

from cortecs_py.client import Cortecs
from cortecs_py.integrations.langchain import DedicatedLLM

cortecs = Cortecs()

with DedicatedLLM(client=cortecs, model_name='cortecs/phi-4-FP8-Dynamic') as llm:
    essay = llm.invoke('Write an essay about dynamic provisioning')
    print(essay.content)

Example

Install

pip install cortecs-py

Summarizing documents

First, set up the environment variables. Use your credentials from cortecs.ai.

export OPENAI_API_KEY="<YOUR_CORTECS_API_KEY>"
export CORTECS_CLIENT_ID="<YOUR_ID>"
export CORTECS_CLIENT_SECRET="<YOUR_SECRET>"

This example shows how to use LangChain to configure a simple summarization chain. The llm is dynamically provisioned and the chain is executed in parallel.

from langchain_community.document_loaders import ArxivLoader
from langchain_core.prompts import ChatPromptTemplate

from cortecs_py.client import Cortecs
from cortecs_py.integrations.langchain import DedicatedLLM

cortecs = Cortecs()
loader = ArxivLoader(
    query="reasoning",
    load_max_docs=40,
    get_ful_documents=True,
    doc_content_chars_max=25000,  # ~6.25k tokens, make sure the models supports that context length
    load_all_available_meta=False
)

prompt = ChatPromptTemplate.from_template("{text}\n\n Explain to me like I'm five:")
docs = loader.load()

with DedicatedLLM(client=cortecs, model_name='cortecs/phi-4-FP8-Dynamic') as llm:
    chain = prompt | llm

    print("Processing data batch-wise ...")
    summaries = chain.batch([{"text": doc.page_content} for doc in docs])
    for summary in summaries:
        print(summary.content + '-------\n\n\n')

This simple example showcases the power of dynamic provisioning. We summarized 224.2k input tokens into 12.9k output tokens in 55 seconds. The llm can be fully utilized in those 55 seconds enabling better cost efficiency. Comparing to serverless open source model providers we observe the following:
