README

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

Install

composer require careerstudiomax/cstm2

Quickstart

<?php
require 'vendor/autoload.php';

use CareerStudioMax\CSTM2\CSTM2Client;

$client = new CSTM2Client('cstm_lm_your_key_here');

$resp = $client->careerlm->chat(['messages' => [['role' => 'user', 'content' => 'Write a cover letter opener for a Senior PM role']]]);
echo $resp['choices'][0]['message']['content'];

Streaming

$client->careerlm->chatStream(
    ['messages' => [['role' => 'user', 'content' => 'Draft a resignation letter']]],
    function (array $event) {
        echo $event['text'] ?? '';
    }
);

Each model family needs its own key

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