This model's cache
This model page returns the exact headers below. The page and /api/models/openai--gpt-5.1 share the model:openai--gpt-5.1 tag, so invalidation stays scoped to this model.
/models/openai--gpt-5.1public, max-age=300, stale-while-revalidate=3600catalogmodel:openai--gpt-5.1Workers 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',

}),
})Invalidate this cache tag
await ctx.cache.purge({ tags: ['model:openai--gpt-5.1'] })Use this when one model changes and you do not want to evict the whole catalog.
