reCaptcha is a free, third party service that is simply integrated into Gravity Forms. There aren't too many options available and at this point and I'm not aware of any options currently available to limit the characters or otherwise manipulate the output.
There is now an option to integrate with the Really Simply Captcha plugin. If you have it installed, you can choose to use it instead of the reCaptcha field. It's less obtrusive and you can customize it a bit more as well.
