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.

What developers say about Kling O1 Text-to-Video
Summarised from public developer discussions and write-ups. Opinions are the sources’, not LLM.API’s.
- Developers note that Kling O1's Multimodal Visual Language (MVL) architecture improves subject consistency across frames because the underlying motion model and identity encoding are shared across its various generation modes.
- Developers on ComfyUI highlight the KlingOmniProTextToVideoNode, which allows for programmatic integration of the model into custom JSON graphs and automated workflows using TypeScript or Python SDKs.
- Technical documentation emphasizes that the Text-to-Video mode utilizes an asynchronous API, requiring developers to fetch results via a task ID after submitting prompts with specific duration and aspect ratio parameters.
