The short version

  • Each has a real cost: BigQuery ML not available in BigQuery's Standard edition, so the cheapest tier cannot use it; Python no built-in GUI module in standard library; requires third-party libraries for desktop applications
  • They diverge on capability: BigQuery ML covers SQL-based ML, Python covers High-level syntax.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

BigQuery ML

  • Not available in BigQuery's Standard edition, so the cheapest tier cannot use it
  • Billed through BigQuery compute and storage rather than as its own product, so training cost tracks data scanned
  • Remote models incur extra Agent Platform charges on top
  • Externally trained model types such as boosted trees and AutoML run through Agent Platform rather than inside BigQuery

Python

  • No built-in GUI module in standard library; requires third-party libraries for desktop applications
  • Global Interpreter Lock (GIL) limits true multithreading for CPU-bound operations

Questions people ask

Is BigQuery ML or Python better?
Neither clearly leads. BigQuery ML starts at Free and Python at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, BigQuery ML or Python?
BigQuery ML starts at Free and Python at Free.
Does BigQuery ML or Python run on more platforms?
BigQuery ML runs on Web. Python runs on Windows, macOS, Linux, Android, iOS.
Can I use BigQuery ML for free?
Both have a free tier, so you can try either at no cost before committing.
What is BigQuery ML best used for?
BigQuery ML is most often used for training models in sql without exporting data, linear and logistic regression on warehouse data, k-means clustering and matrix factorisation for recommendations, time series forecasting with arima_plus. Of those, training models in sql without exporting data and linear and logistic regression on warehouse data are not what Python is typically brought in for.
What can BigQuery ML do that Python cannot?
BigQuery ML covers SQL-based ML, AutoML Tables, Model export, Prediction functions. Python covers High-level syntax, Interpreted execution, Object-oriented programming, Dynamic typing. Both handle TensorFlow.

Answered from the vendors’ own pages

BigQuery ML: How much does Google Cloud BigQuery ML cost?

BigQuery ML pricing is not specified separately on Google Cloud's pricing page. It follows the same pay-as-you-go model as BigQuery, charging per terabyte of data scanned during analysis. Customers receive $300 in free credits and can use 20+ products free up to monthly limits.
