No need to create multiple cloud accounts.</p> <p><strong>Step 1 — Install the SDK</strong></p> <p><code>pip install openai</code></p> <p><strong>Step 2 — Initialize the client</strong></p> <p>Point&nbsp;<code>base_url</code>&nbsp;to RouteAI's endpoint, set your RouteAI key, and use the model ID directly (e.g.&nbsp;<code>qwen3.7-plus</code>,&nbsp;<code>deepseek-v4-flash</code>,&nbsp;<code>kimi-k2.6</code>). Everything else — streaming, function calling, extended params like&nbsp;<code>enable_thinking</code>&nbsp;— works identically to the OpenAI SDK.</p> <p><strong>Current pricing highlights:</strong></p> <ul> <li>DeepSeek V4 Flash:&nbsp;<strong>$0.12/M</strong>&nbsp;input (official: $0.20)</li> <li>Qwen3.7 Plus:&nbsp;<strong>$0.24/M</strong>&nbsp;(official: $0.40)</li> <li>Qwen3.5 Flash:&nbsp;<strong>$0.06/M</strong>&nbsp;(official: $0.10)</li> <li>Kimi K2.6:&nbsp;<strong>$1.004/M</strong>&nbsp;(official: $1.34)</li> </ul> <p>All usage is tracked in one dashboard. No more logging into three separate cloud consoles to reconcile billing.</p>
