Frequently asked

What is the difference between Inference and Mixture of Experts?

Inference: Inference is what happens when you actually run a trained model on new input. For LLMs that means generating tokens one at a time, with sampling and a KV cache. Mixture of Experts: Mixture of Experts is a transformer variant where each layer has many parallel "expert" feed-forward networks, but only a few are activated per token. Total parameters grow without growing per-token compute.

When should I use Inference vs Mixture of Experts?

Inference is the right concept when you are focused on inference. When you want frontier-scale capability without paying frontier-scale per-token compute.

Are Inference and Mixture of Experts the same thing?

No. Inference is inference; Mixture of Experts is architecture. They are related but address different parts of the AI stack.
