25times
Google's 2019 server-side search graph was about 25 times the size of the on-device Gboard model it announced in the same post.
Checked against its source on October 17, 2026
- What it measures
- Calculated from Google's 2019 statements: its server-side search graph was almost 2 GB, and its on-device Gboard model was 80 MB after compression. The ratio is an upper bound because the server graph was 'almost' 2 GB.
- How it is calculated
- 2 GB = 2,000 MB (Google said almost 2 GB, so this is an upper bound); 2,000 MB / 80 MB = 25.
Calculated from
- Google said its traditional server-side recognizer used a search graph of almost 2 GB, too large for a phone, which is why it needed a connection.
- In 2019 Google moved Gboard voice typing onto the phone with an 80 MB speech recognizer that works even when the phone is offline, first on Pixel phones in American English.
