Hi!
Im trying to generate html and CSS code in a structured output with Gemini 2.5 Pro Preview 05-06.
Every 1 in 3 attempts the output is truncated, it will get through the CSS part no problem, then get to html and get cut off, it will still close the JSON though.
I’m using the vertex API, I have temp set to 0.3, max token to the 65k, and i clearly state in the prompt telling the model it has 65k tokens it cant stop until it’s done the output, etc.
Not sure what to do at this point.
Hi @JacobFerrari, If possible could you please share the reference/screen shot where the model response was Truncated. Thank You.
Of course. I log each response.

With all due respect, showing the response itself is completely pointless to troubleshoot this and is the opposite of what you should be asking @JacobFerrari for. All you will see is a truncated response from the model.
Jacob, share the prompt you used immediately prior to that response, giving the model instructions to get that output, and I bet I can spot the issue. This is a known constraint, and there is a prompting method to resolve it.
