Question 1

How do I use the Meta Contributor 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 muse-spark-1.3-contributor. On pay-as-you-go keys, meta-contributor/muse-spark-1.3-contributor pins every request to Meta Contributor; DevPass coding plans do not support provider pinning. You do not need a separate Meta Contributor account or SDK.

Question 2

Which Meta Contributor models are available?

Accepted Answer

LLM Gateway serves 2 Meta Contributor models: Muse Spark 1.3 Contributor, Muse Spark 1.2 Contributor. Each model page lists per-token pricing, context window and capabilities.

Question 3

Does Meta Contributor train on API data?

Accepted Answer

Yes. Meta Contributor's published policy allows training on API traffic. Use provider routing rules in LLM Gateway to keep sensitive workloads on providers that do not.

Question 4

Where is Meta Contributor based?

Accepted Answer

Meta Contributor is headquartered in United States. LLM Gateway shows each provider's location and data policy so you can route by compliance requirements.

Question 5

What happens if the Meta Contributor 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 Meta Contributor does not have to take your app down. Send X-No-Fallback: true with a provider-pinned model when every request must reach Meta Contributor.
