A developer demonstrates how to configure the OpenAI SDK to point at RouterBase's endpoint, enabling quick testing of different models like Google's Gemini 2.5 Flash without altering the application's core logic.", "body_md": "If your application already uses OpenAI-style chat-completions calls, the lowest-friction way to test another routing layer is to keep the client code familiar and change only the base URL, API key, and model id.\n\n[RouterBase](https://routerbase.com) is designed for that kind of experiment. It exposes an OpenAI-compatible endpoint at `https://routerbase.com/v1`\n\n, so existing SDK setup can stay close to what developers already know.\n\n```\nROUTERBASE_API_KEY=your_routerbase_key\nROUTERBASE_BASE_URL=https://routerbase.com/v1\nROUTERBASE_MODEL=google/gemini-2.5-flash\n```\n\nKeeping the model in configuration makes it easier to compare providers later without editing the application path that calls the model.\n\n``` python\nimport OpenAI from \"openai\";\n\nconst client = new OpenAI({\n  apiKey: process.env.ROUTERBASE_API_KEY,\n  baseURL: process.env.ROUTERBASE_BASE_URL || \"https://routerbase.com/v1\"\n});\n\nconst completion = await client.chat.completions.create({\n  model: process.env.ROUTERBASE_MODEL || \"google/gemini-2.5-flash\",\n  messages: [\n    {\n      role: \"user\",\n      content: \"Write a one-paragraph changelog entry for a developer tool.\"\n    }\n  ]\n});\n\nconsole.log(completion.choices[0]?.message?.content);\n```\n\nBefore using the setup in a production workflow, run a short checklist:", "url": "https://wpnews.pro/news/point-the-openai-sdk-at-routerbase-in-a-few-minutes", "canonical_source": "https://dev.to/routerbasecom/point-the-openai-sdk-at-routerbase-in-a-few-minutes-epm", "published_at": "2026-06-30 17:17:47+00:00", "updated_at": "2026-06-30 17:49:20.439513+00:00", "lang": "en", "topics": ["developer-tools", "large-language-models", "ai-infrastructure"], "entities": ["RouterBase", "OpenAI", "Google", "Gemini 2.5 Flash"], "alternates": {"html": "https://wpnews.pro/news/point-the-openai-sdk-at-routerbase-in-a-few-minutes", "markdown": "https://wpnews.pro/news/point-the-openai-sdk-at-routerbase-in-a-few-minutes.md", "text": "https://wpnews.pro/news/point-the-openai-sdk-at-routerbase-in-a-few-minutes.txt", "jsonld": "https://wpnews.pro/news/point-the-openai-sdk-at-routerbase-in-a-few-minutes.jsonld"}}
