The influence of the (pseudo-)random number generator is called "temperature" in most models. Setting it to 0 in theory eliminates all randomness, and instead of choosing one from a list of next words that may be predicted, always only the MOST PROBABLY word would be chosen. However, in practice, setting the temperature to 0 in most GUIs does not actually set the temperature to 0, but to a "very small" value ("epsilon"), the reason being to avoid a division by zero exception/crawsh in a mathematical formula. So don't be surprised if you cannot get rid of random behavior entirely.
