Batch API - Model `gpt-5.4-mini-2026-03-17-batch` does not exist or you do not have access to it

Yeah, that’s definitely confusing, especially if it was working fine just a few days ago. The model gpt-5.4-mini-2026-03-17 is supported for the Batch API. Since you’ve already tried updating the model name, refreshing your API key, and upgrading the SDK, it sounds like you’ve covered the usual troubleshooting steps. To help narrow this down further, could you share a few request IDs from the affected batch jobs? You can find the request ID in the response headers of your API calls. Appreciate you sharing the detailed context. - Sky
