CSTM-2 Python SDK

Official client for the CareerStudioMax CSTM-2 API — 8 independent, career-native model families.

Install

pip install careerstudiomax-cstm2

Quickstart

from cstm2 import CSTM2Client

client = CSTM2Client(api_key="cstm_lm_your_key_here")

result = client.careerlm.chat(
    messages=[{"role": "user", "content": "Write a cover letter opener for a Senior PM role"}]
)
print(result["choices"][0]["message"]["content"])

Streaming

def on_chunk(event):
    print(event.get("text", ""), end="", flush=True)

client.careerlm.chat_stream(on_chunk, messages=[{"role": "user", "content": "Draft a resignation letter"}])

Each model family needs its own key

A cstm_lm_* key only works on careerlm endpoints; a cstm_em_* key only works on careerembed, and so on. Generate one key per family you use at careerstudiomax.com/developer.

Errors

from cstm2 import CSTM2Client, CSTM2Error

try:
    client.careerembed.embed("some text")
except CSTM2Error as e:
    print(e.code, e.status, str(e))

Context manager

with CSTM2Client(api_key="...") as client:
