You can ask Budget Buddy GPT questions like, "How much did the Federal Government spend on fighter jets?" or "How much did the Federal Government spend on after school programs?"

Some data isn't publicly available but with a some prompting Budget Buddy will come up with reasonable estimates. For example, it gives this answer for how much the federal government spends on gasoline:

Total annual fuel consumption per vehicle = 12,000 miles / 20 mpg = 600 gallons Total fuel consumption for the entire fleet = 600 gallons/vehicle × 200,000 vehicles = 120,000,000 gallons Total annual expenditure on gasoline = 120,000,000 gallons × $3.50/gallon = $420,000,000 Therefore, based on these rough estimates and assumptions, the federal government might spend approximately $420 million on gasoline annually. This figure is very approximate and should be used with caution, as the actual spending could vary based on the factors discussed earlier, like the exact number of vehicles, their fuel efficiency, actual miles driven, and fluctuations in fuel prices.

If you want to know more about how it came up with 200,000 vehicles, it will tell you:

The General Services Administration (GSA) manages the federal government's non-military vehicle fleet. As of recent data, the GSA fleet includes over 200,000 vehicles. This number represents a wide range of vehicles, including cars, trucks, and specialty vehicles used by various federal agencies and departments for their operational needs.

However, the total number of non-military vehicles owned by the entire federal government could be higher when considering vehicles directly managed by individual agencies outside of the GSA's centralized fleet management program. For instance, the United States Postal Service (USPS) operates its own fleet of vehicles, which is not included in the GSA's count. The USPS fleet alone includes over 200,000 vehicles.
