|---|---|---|
401 | Missing or invalid API key. | Send Authorization: Bearer YOUR_LLMAPI_KEY and check the key is active. |
429 | Rate limited, or the upstream provider is throttling the request. | Back off and retry with jitter; the gateway also retries the request on another provider where one is available. |
5xx | Upstream provider error or timeout. | Retry; fallback routing sends the retry to the next healthy provider for this model. |
When a provider fails or throttles, the request is routed to the next provider serving this model — the ones listed in the providers table above.

COMMUNITY
What developers say about Qwen Image Plus
Summarised from public developer discussions and write-ups. Opinions are the sources’, not LLM.API’s.
- Developers on GitHub report that Qwen Image Plus excels at maintaining character identity when using masked denoising for inpainting, outperforming other versions for identity consistency during image edits.
- Developers have successfully experimented with depth extraction preprocessing for the model, noting that it appears to support depth-based control even within image inpainting workflows.
- Developers indicate that using masked denoising to 'paint all' can effectively preserve identity while allowing for prompt-based changes, though they note the Gradio-based mask editors can be difficult to use.
