Speed
Response time
On , GPT-5.6 Sol's daily response-time probe recorded a median completion time of 2.7 s across three successful responses at high reasoning effort and Standard/default service.
The daily local probe is scheduled at 00:10 UTC. It uses high reasoning effort and three successful fresh single-turn responses to one fixed small task. A day without three successful responses has no point. Lower is faster; dates are UTC.

Output speed
On , GPT-5.6 Sol's Nerf Watch run recorded 65 output tokens per second.
Tokens per second from the daily Nerf Watch run, scheduled at 01:00 UTC: total output tokens divided by total completion time across its four fixed tasks. Effort is low, except DeepSeek V4 Pro uses high, its lowest available variant. Service is Standard/default, or Ultrafast for the two Ultrafast lines. Output includes reported reasoning or thinking tokens once; OpenCode’s separately reported reasoning is added to output. Timing includes waiting within the measured turn and excludes setup and process exit. Higher is faster; dates are UTC.
