Common questions about Model Studio applications and data management.
Tools and billing
What built-in tools are available?
Model Studio provides three built-in tools:
- Python code interpreter
- Calculator

Am I charged for custom tools?
No. Custom tools are free. Charges apply only for prompt optimization, application calls, and test window usage during agent API setup.
Agents and the Assistant API
How does the assistant handle custom tool and function parameters?
The assistant understands custom API tools and follows the protocol to pass parameters to the model. For functions, the model learns from input parameters and returns comprehensive results.
What is the difference between an agent and the Assistant API?
The Assistant API provides simplified tuning options.
Can Model Studio pass custom headers to my tool's endpoint?
No. Only authorization headers are passed through.

In parallel. RAG queries all knowledge bases simultaneously, then selects the top N results by score.
Streaming and output formatting
How do I enable incremental streaming output through the API?
Set two parameters in your API request:
Why does model output show bold markers instead of formatted text?
The ** ** syntax is standard Markdown for bold text. Parse and render Markdown in your frontend to display bold formatting correctly.
Data management
Why does my PDF upload fail with error code 140010?
