What issue are you seeing?

My GPT-5.3-Codex-Spark usage page shows 100% remaining for both the 5-hour and weekly Spark limits. However, GPT-5.3-Codex-Spark does not appear in the Codex model selector.

My regular Codex and Work usage limit is exhausted, and the app asks me to add credits or wait for the regular quota reset. Since the Spark allowance is shown as separately available at 100%, I expected to be able to select and use GPT-5.3-Codex-Spark, but the model is not available in the selector.

The model selector currently shows Default, GPT-6 Astra, GPT-5.6 Sol, GPT-5.6 Terra, GPT-5.6 Luna, and GPT-5.5, but no GPT-5.3-Codex-Spark.

Please check whether the Spark entitlement or model availability is not syncing correctly with my account.

Start with the reported Feedback ID 01a02dbb-c2d2-74b1-8b1b-8b8c-de284117ae76 and trace how account entitlements reach the Codex model selector. Confirm why GPT-5.3-Codex-Spark is absent despite both Spark quotas showing 100% remaining; done means an eligible Pro account can select the model or receives an accurate availability state.
