Frequently Asked Questions about OpenRouter AI
What is OpenRouter AI?▾
OpenRouter AI is a platform that provides an API gateway and management layer for running and routing requests to large language models, aimed at developers who want flexible model access and deployment options.
How does OpenRouter AI differ from other providers like OpenAI?▾
Platforms like OpenRouter AI typically focus on routing between multiple models (including open-weight models), offering more deployment choices and control over hosting and privacy compared with single-provider closed APIs.
Which models can I use with OpenRouter AI?▾
These platforms commonly support a range of open-source and hosted models; the exact available models and versions are listed in the project documentation or model catalog on the website.
Can I self-host OpenRouter AI or is it only offered as a hosted API?▾
Many similar projects offer both a hosted API and self-hosting/deployment options so you can run components on your own infrastructure for greater control; check the documentation for supported deployment guides and system requirements.
How do I get an API key to start using the service?▾
You typically sign up on the website, create an account, and generate an API key from the dashboard or account settings to authenticate requests to the API.
What are the pricing and rate limits?▾
Pricing and rate limits vary by plan and are normally published on the project site; most services offer tiered plans and often a free trial or free tier with usage limits—see the pricing page for details.
How is data privacy and retention handled?▾
Platforms generally encrypt traffic in transit and document data retention and logging policies in their privacy policy; self-hosting options can provide full data control if you need to avoid provider-side storage.
Are there SDKs or client libraries available?▾
Similar projects commonly provide official or community SDKs for languages like Python and JavaScript plus an OpenAI-compatible HTTP interface; check the docs or GitHub repository for client libraries and examples.
Can I fine-tune models or upload custom models?▾
Support for fine-tuning or uploading custom models varies by platform; some enable fine-tuning of compatible open models or importing custom weights, while others focus on routing to pre-hosted models—consult the documentation for supported workflows.
How do I get help or report issues?▾
You can usually find help through the project documentation, FAQ, community forums or chat, and by filing issues in the project’s GitHub repository or contacting support via the website’s contact channels.
