This model's cache

This model page returns the exact headers below. The page and /api/models/openai--gpt-5.4-pro share the model:openai--gpt-5.4-pro tag, so invalidation stays scoped to this model.

Workers 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',
    'Cache-Tag': 'catalog,model:openai--gpt-5.4-pro',
  }),
})

Invalidate this cache tag

await ctx.cache.purge({ tags: ['model:openai--gpt-5.4-pro'] })

Use this when one model changes and you do not want to evict the whole catalog.
