How these speeds are measured
- Every number comes from real chats in Loci, timed on the device that wrote the answer, with Loci's default settings.
- Tokens per second is how fast an answer is written once it starts. Four characters of text count as one token, for every model and device. Reading pace is about 5.
- First word is how long an answer takes to start after you send a message. Longer conversations take longer.
- Each device counts once. The large number is the median; the typical range covers the middle half of devices.
- Answers written in Low Power Mode or Battery Saver, in the background, or with web search or other tools are left out.
