Prompt starters
Replace the bracketsStarter
Inspect the supplied image for [task]. Separate direct observations from inferences, extract [required fields], and return the result as [format].
Starter
Complete [goal]. Use [available tools] only when needed, validate every tool result before continuing, and return [required final format].
Starter
Answer [user task] in a clear structure. Put the direct result first, keep each section self-contained, and avoid delaying essential information until the end.

FAQ
GLM-5.3-Flash API questions
What model ID should I use for the GLM-5.3-Flash API?+
Use glm-5.3-flash in the model field. This is the stable PixMind route identifier shown in the playground request JSON.
Which endpoint does the GLM-5.3-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.
