Question 1

How do I use the Luminal API?

Accepted Answer

Create an LLM Gateway API key and point any OpenAI-compatible SDK at https://api.llmgateway.io/v1. Set the model to deepseek-ai/DeepSeek-V4.1-Flash. On pay-as-you-go keys, luminal/deepseek-ai/DeepSeek-V4.1-Flash pins every request to Luminal; DevPass coding plans do not support provider pinning. You do not need a separate Luminal account or SDK.

Question 2

Which Luminal models are available?

Accepted Answer

LLM Gateway serves 1 Luminal model: luminal/DeepSeek-V4.1-Flash. Each model page lists per-token pricing, context window and capabilities.

Question 3

What happens if the Luminal API is down?

Accepted Answer

When you request a model without a provider prefix, LLM Gateway retries failed requests on other providers that serve the same model, so an outage at Luminal does not have to take your app down. Send X-No-Fallback: true with a provider-pinned model when every request must reach Luminal.
