[Model Studio] Notice of Changes to Certain Model Fields

Affected Time

2026-04-20 00:00:00 (UTC+08) (Depending on the actual time)

Change Model

All models in Model Studio that are compatible with the OpenAI API protocol

Change Details

Completions API: The parameter controlling the total number of tokens generated by the model (including reasoning/output tokens, excluding input tokens) will be updated to the new parameter max_completion_tokens. The legacy parameter max_tokens will remain compatible for a short transition period and will be deprecated before May 30, 2026.

  • Friendly Reminder: If you have previously used the max_completion_tokens parameter incorrectly in your API calls, please update your code promptly, as this may cause API errors once the parameter change officially takes effect.

Responses API: The parameter controlling the total number of tokens generated by the model (including reasoning/output tokens, excluding input tokens) will be updated to the new parameter max_output_tokens.

Thank you for your support and trust in Model Studio.
