FAQ
DeepSeek V4.1 Flash API questions
What model ID should I use for the DeepSeek V4.1 Flash API?+
Use deepseek-v4.1-flash in the model field. This is the stable PixMind route identifier shown in the playground request JSON.
Which endpoint does the DeepSeek V4.1 Flash API use?+
Send POST requests to /v1/chat/completions. Keep your API key on your server and pass it as a Bearer token.
Is the playground using a real API request?+
Yes. When you click Run model, PixMind forwards the displayed payload with the API key you entered. A successful request may create a paid task.
Does PixMind save the API key entered here?+
No. The playground keeps the key only in component memory and sends it for the current request; it is not written to browser storage.
Is API pricing the same as PixMind Studio pricing?+
No. API usage resolves through the apiPlatform pricing role and a separate pay-as-you-go ledger. Studio pricing includes the creation interface and product workflow services.
Why can the final price differ from the starting price?+
The entry price reflects the configuration displayed on this page. Resolution, duration, quality, audio, references, and output count can affect the final task price.
How do I receive a finished image or video?+
Generation routes can return an asynchronous task. Save its ID and query the task endpoint until the status is succeeded, failed, or cancelled.
Can I use the same integration for other PixMind models?+
Yes. Models in the same workload family share the generation contract, so switching usually means changing the model ID and supported parameters.
