+
+# Seedream 4.0
+
+ByteDance's image model. Text to image, up to 4K.
+
+Runs [`bytedance/seedream-v4`](https://wavespeed.ai/models/bytedance/seedream-v4) through the
+[WaveSpeed](https://wavespeed.ai) v3 API.
+
+## Bring your own API key
+
+This Space does not ship an API key. Paste your own in the field at the top —
+create one in the [WaveSpeed dashboard](https://wavespeed.ai/dashboard).
+
+Your key is sent only to `api.wavespeed.ai` to run the model. It is not stored,
+not logged, and not written to disk; it is stripped out of error messages
+before they are displayed, and Gradio's flagging and API-page features (both of
+which would otherwise record or republish inputs) are disabled. Generations are
+billed to your own account.
+
+## Development
+
+Source of truth is `_shared/` in the working repo, not this copy:
+
+    python3 _shared/build_apps.py

+"""Builds a Space UI from a declarative spec.
+
+Shared verbatim by every Space in the wavespeed org. Generated from
+_shared/spaceapp/ — edit there and re-run _shared/build_apps.py.
+
+Handling of the user's API key
+------------------------------
+The key is typed into the browser and travels to this server on each request.
+Keeping it from leaking takes more than masking the textbox, because Gradio has
+several features that will happily persist or republish an input:
+
+  * `type="password"`          - not echoed back into the DOM.
+  * `api_visibility="private"` - Gradio 6 otherwise documents this event on the
+                                 app's public API page, generating client
+                                 snippets that include every input, the key
+                                 among them.
+  * `analytics_enabled=False`  - on Blocks, plus the env vars set in app.py
+                                 before gradio is imported.
+  * no `gr.State`/`gr.Examples` ever holds the key, so it is not serialised
+    into the page or cached to disk.
+  * every error is passed through `wavespeed.redact` before display, because a
+    requests exception can stringify the Authorization header.
+
+Gradio's flagging feature (which writes raw inputs to a CSV) belongs to
+gr.Interface; this UI is built from gr.Blocks, which has no flagging, so there
+is nothing to switch off there.
+
+The key is a plain function argument: it lives for the duration of one request
+and is not retained between them.

+"""Minimal WaveSpeed v3 API client.

+Shared verbatim by every Space in the wavespeed org. Generated from
+_shared/spaceapp/ — edit there and re-run _shared/build_apps.py, never edit the
+copy inside a Space.
+
+The user supplies their own API key through the UI. It is used to sign requests
+to api.wavespeed.ai and nothing else: it is never logged, never written to
+disk, never placed in a Gradio component value, and is stripped out of every
+error message before that message can reach a browser (see `redact`). An
+exception raised by `requests` can carry the full request headers in its text,
+which is exactly how a key ends up in a user-visible traceback, so every raise
+in this module goes through `redact` first.
