# Model Studio error codes: reading 1301-1313 instead of retrying blindly

## TL;DR

Map the error code before you act: 1301 means reword the prompt, not retry; 1302/1303/1305 mean back off or raise limits; 1309/1311 mean billing or plan changes, not code changes; 1312 means fail over to a different model. Logging the raw code with each failure saves hours of guessing. Context: Official docs (Model Studio error reference): documents model-side error codes such as 1301 (unsafe or sensitive content blocked), 1302/1303/1305 (concurrency, request rate, traffic limits), 1304/1310 (daily and weekly/monthly usage limits), 1309 (coding plan expired, needs renewal), 1311 (model not covered by your plan), and 1312 (model under high traffic, try another model).

Use this when you run into the situation in the title.
