Línea de trabajo

Empieza en camel/model_backend.py, donde el traceback muestra que se realiza la solicitud de chat completion de OpenAI, y sigue cómo max_tokens se convierte en 14817. Reproduce el comando documentado de run.py y, a continuación, verifica que la solicitud se mantenga dentro del límite del modelo seleccionado y que la tarea Snake Game ya no falle con BadRequestError.

Descripción

When I tried to run ChatDev with the following command:
python3 run.py --task "[make a simple Snake Game game]" --name "[Snake_Game]"

I get this error:


Traceback (most recent call last):

The above exception was the direct cause of the following exception:

Expected Behavior

The program should correctly calculate max_tokens based on the model limits (e.g., gpt-4o supports 4096 tokens).

Actual Behavior

It sets max_tokens=14817, which exceeds the model’s maximum (4096), causing the OpenAI API to return BadRequestError.
