Superseded by Intern S2 Preview FP8. It no longer holds a current-board position.

This separately configured or accelerated route is reviewed as the same underlying model identity as Intern S1. That canonical product owns rank and capability evidence; pricing, providers and other operational differences remain route-specific below.

OpenRouter endpoint status could not be refreshed. This model is not treated as currently served until a successful observation arrives.
