FAQ

What is an LLM inference API?

An inference API runs a trained language model for you: you send a request with a prompt, and the API returns the model's output. You pay per token instead of running GPUs yourself.

Which models can I run on RouterPlus?

43 models from Particle, Ultramarine, Kimi, DeepSeek, GLM, Qwen, Gemma 4, Muse Spark, gpt-oss and MiniMax M3, served by 16 providers. Each model page lists every provider and its price.

How much does inference cost?

Prices start at $0.03 per million input tokens (gpt-oss-20b) and $0.14 per million output tokens (gpt-oss-20b). Marketplace calls use prepaid credits at the listed model rates, with the cost included in each billed response. With your own provider key, the provider bills you directly and RouterPlus charges a 0% inference fee.

Is the API OpenAI-compatible?

Yes. Existing OpenAI- or Anthropic-compatible clients connect by changing the base URL to https://api.routerplus.com/v1 and using your RouterPlus key. To switch models, change the model field.

How fast can I start?

Sign up in the console and you get API access right away. There is no waitlist or approval step.

Does RouterPlus store my prompts?

The gateway does not store prompts or completions; it records usage metadata. The provider serving your request applies its own data policy.

Can I get dedicated or reserved capacity?

Yes. Send the model, throughput and region you need, and RouterPlus shops the requirement across its provider network and replies with committed capacity, a better quote or a backup provider.
