 Check out the configuration reference at https://huggingface.co/docs/hub/spaces-config-reference
+
+This Space runs the official New API image behind a small response adapter. All
+requests are proxied unchanged except successful `/v1/images/generations` and
+`/v1/images/edits` responses containing `data[].url` without `b64_json`. For
+those responses, the adapter downloads the public image URL and returns the
+official Base64 response shape expected by OpenAI-compatible clients.
+
+The default mode is `b64_json`. A caller that needs the original URL can set
+`response_format: "url"` in a JSON generation request or send
+`X-Image-Response-Format: url`. The custom header is removed before forwarding.
+Set `IMAGE_RESPONSE_MODE=url` to make URL passthrough the Space-wide default.
+`IMAGE_CONVERSION_MAX_CONCURRENCY` limits simultaneous URL downloads and
+defaults to `4` for CPU Basic hardware.
