This model's cache
This model page returns the exact headers below. The page and /api/models/xai--grok-4.3 share the model:xai--grok-4.3 tag, so invalidation stays scoped to this model.
/models/xai--grok-4.3public, max-age=300, stale-while-revalidate=3600catalogmodel:xai--grok-4.3Workers Cache derives the key from this path/query, plus the Worker entrypoint and current Worker version.
export const Route = createFileRoute('/models/$modelSlug')({
headers: () => ({
'Cache-Control': 'public, max-age=300, stale-while-revalidate=3600',
