## TL;DR

For DataInspectionFailed, adjust the input or output prompts (or change the input image) to pass moderation; do not try to work around the content policy. Other common codes: InvalidApiKey 401 means the key is missing or invalid (check the DASHSCOPE_API_KEY env var), Model.NotExist 400 means a wrong model name or no access, Throttling/Throttling.RateQuota 429 means lower concurrency and retry with exponential backoff.

## Fix

1. For DataInspectionFailed, adjust the input or output prompts (or change the input image) to pass moderation; do not try to work around the content policy.
   Expected: You get the expected result; the problem is gone.

## When to use

- You are setting up or using this Alibaba Cloud Model Studio feature.
- The symptom matches: DataInspectionFailed 400 blocked by content safety review.

## When NOT to use

- Unrelated Alibaba Cloud Model Studio issues (different feature, different failure).
- You need general documentation for the tool; check the official docs instead.

## Variant phrasings

### DataInspectionFailed 400 blocked by content safety review

## Why it happens

A DashScope (Model Studio) call returns HTTP 400 with code DataInspectionFailed instead of a model response. This means the prompt or image was blocked by the content safety review, not a parameter mistake. A related gotcha: Generation.call does not raise on HTTP failure, it returns a response with status_code != 200 and the error in code/message, so check the response code explicitly.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
