+### BigModel Coding Plan over Responses
+
+Select **Zhipu AI — BigModel Coding Plan (Responses)** (`zhipu-bigmodel-responses`)
+for the `openai-responses` endpoint `https://open.bigmodel.cn/api/v1`. This is separate
+from `zhipu-bigmodel-coding`, which uses Chat Completions at `/api/coding/paas/v4`.
+
+The preset uses a **static roster** (`liveModels: false`) taken from the
+[official BigModel Codex example](https://docs.bigmodel.cn/cn/coding-plan/tool/codex.md):
+
+| Model | Context tokens | Upstream selectable effort | Default effort | Reasoning summaries |
+| --- | ---: | --- | --- | --- |
+| `glm-5.3` | 1,048,576 | `low`, `high`, `max` | `max` | Supported |
+| `glm-5-turbo` | 204,800 | None (empty list) | `max` | Supported |
+
+Both entries declare upstream text-only input. The Codex catalog advertises text and
+image because opencodex's existing vision sidecar can describe images for text-only
+models. Image handling requires an available, enabled vision sidecar; this does not
+declare native BigModel image support.
+
+The default model is `glm-5.3`; Responses reasoning content is preserved on replay.
+The existing Codex export adds its compatibility
+`ultra` tier to GLM-5.3 and omits Turbo's default-effort field because Turbo has no
+selectable ladder; the provider metadata still records `max` for both models.
+For Turbo, outgoing Responses requests omit `reasoning.effort`, including a caller's
+`max` or `ultra`, while preserving requested reasoning summaries. This leaves effort
+selection to the upstream default; opencodex does not inject a selectable or wire `max`.
+
+The example's `models.json` is a local catalog file, not a documented HTTP model-list
+response. This preset does not perform live model discovery. `glm-5.3-flash` is not
+seeded here because its exact Responses metadata is not verified. An existing custom
+provider with the same name keeps its configured destination and metadata.
+CLI key login also skips the undocumented `/models` probe and reports validation as
+unknown; successful key authentication is established by a subsequent inference request.
+
 ### Multiple API keys
 
 Key-based providers can also keep multiple keys. Adding a key through the Providers page stores it
