Max Tokens
The request parameter that sets a hard ceiling on how many tokens a model may generate in one response.
In depth
The request parameter that sets a hard ceiling on how many tokens a model may generate in one response. It caps output, not input, and the model can stop earlier on its own; if it reaches the cap, the output is cut off and the Claude API reports stop_reason "max_tokens". Setting it too low is a common cause of truncated JSON and incomplete tool calls, which have to be retried with a higher limit. Each model has its own maximum value for the parameter.
