The short version

  • Each has a real cost: BigQuery ML not available in BigQuery's Standard edition, so the cheapest tier cannot use it; ChatGPT openAI's own pricing page, as captured by the Internet Archive in 2023, listed ChatGPT Plus at $20 per user per month, Team at $25 to $30 per user per month with a minimum of 2 users, and Enterprise available only from 150 users. The live page refuses automated reads, so these are 2023 figures and the tiers have changed since.
  • They diverge on capability: BigQuery ML covers SQL-based ML, ChatGPT covers Natural language conversation.
  • Prices and features above were last checked on 30 August 2026.

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

ChatGPT

  • OpenAI's own pricing page, as captured by the Internet Archive in 2023, listed ChatGPT Plus at $20 per user per month, Team at $25 to $30 per user per month with a minimum of 2 users, and Enterprise available only from 150 users. The live page refuses automated reads, so these are 2023 figures and the tiers have changed since.
