What this error means
GPT-5.4-Mini returns 500 internal errors with ResponseInputImageParam is a OpenAI API failure pattern reported for developers trying to fix gpt-5.4-mini 500 internal server error when sending images. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.
Why this happens
95% failure rate on GPT-5.4-Mini with image inputs. Same request on GPT-5.4 works fine. Affects openai-python SDK v2.31.0 on macOS. Error occurs with ResponseInputImageParam using valid image URLs.
Common causes
- GPT-5.4-Mini consistently returns HTTP 500 when provided with image inputs via ResponseInputImageParam, while GPT-5.4 (full) works perfectly with the same input. This blocks developers from using the cheaper Mini model for vision tasks.
- 95% failure rate on GPT-5.4-Mini with image inputs. Same request on GPT-5.4 works fine. Affects openai-python SDK v2.31.0 on macOS. Error occurs with ResponseInputImageParam using valid image URLs.
Quick fixes
- Confirm the exact error signature matches
GPT-5.4-Mini returns 500 internal errors with ResponseInputImageParam. - Check the OpenAI API account, local tool state, and provider configuration involved in the failing workflow.
- Compare the failing environment with a known working setup, then change one configuration value at a time.
Platform/tool-specific checks
- Verify the command, editor, extension, or API client that produced the error.
- Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
- Avoid deleting credentials, local model data, or project settings until the failing scope is clear.
Step-by-step troubleshooting
- Capture the exact error message and the command, editor action, or request that triggered it.
- Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
- Review the source evidence below and compare it with your environment.
- Apply one change at a time and rerun the smallest failing action.
- Keep the working fix documented for the team or deployment environment.
How to prevent it
- Keep provider/tool configuration documented.
- Record non-secret diagnostics such as tool version, provider name, model name, and command path.
- Add a lightweight check before CI or production workflows depend on the tool.

FAQ
What should I check first?
Start with the exact GPT-5.4-Mini returns 500 internal errors with ResponseInputImageParam text and the smallest action that reproduces it.
Can I ignore this error?
No. Treat it as a failed OpenAI API workflow until the root cause is understood.
Is this guaranteed to have one fix?
No. The imported evidence supports the troubleshooting path above, but tool behavior can vary by account, plan, version, provider, and local configuration.
How do I know the fix worked?
Rerun the same command, editor action, or request. The fix is working when that action completes without GPT-5.4-Mini returns 500 internal errors with ResponseInputImageParam.
