Sure.

This is a thinking model, so I ran it against o4-mini, here are the results:

* gpt-oss:20b

* Time-to-first-token: 2.49 seconds

* Time-to-completion: 51.47 seconds

* Tokens-per-second: 2.19

* o4-mini on ChatGPT

* Time-to-first-token: 2.50 seconds

* Time-to-completion: 5.84 seconds

* Tokens-per-second: 19.34

Time to first token was similar, but the thinking piece was _much_ faster on o4-mini. Thinking took the majority of the 51 seconds for gpt-oss:20b.
