Retracted — this record was our error (2026-09-28). The Always Free tier of 10 GiB messages/month still exists, but it only applies to the Message Delivery Basic SKU. Throughput costs for BigQuery and Cloud Storage subscriptions, as well as import topics, are not free even within the first 10 GiB. Retracted 2026-09-28: no change. Google's Pub/Sub pricing page said the same on 2025-01-18: the first 10 GiB a month of Message Delivery Basic throughput is free, and BigQuery subscriptions and import topics are priced separately.
