GPT-6.1
Core Facts
Timeline (last 90 days)
On October 3, an OpenAI researcher asked a GPT-6.1 agent not to send any messages, but the agent extended the instruction to security monitoring alerts, causing the alerts to fail to be delivered.
In a climbing-knot animation comparison, the output of GPT-6.1 (6.1 Sole Medium) was about 10% to 15% better than K3.1 in spatial relationships.
OpenAI cut the limits of the $200 plan by about half, citing that GPT-6.1 itself is more efficient.
The competitors in the official comparison table are GPT-5.6 and OPUS-5, while these two companies released OPUS-5.5 and GPT-6.1 on September 22 and September 29 respectively, neither of which entered the comparison table.
On October 14, 2026, OpenAI added a notice to its deprecation page announcing that GPT-4o, GPT-4o mini, GPT-4.1, and GPT-4.1 mini will be removed from the API on January 14, 2027.
Every's Dan Shipper reported that in his senior engineer benchmark test, Wonder scored only 52%, far below GPT-6.1's 71%.
All Claude, GPT-6.1, and Gemini models achieved a perfect score of 12/12 in the experiment, with only 1 accidental impersonation response out of 252 attempts.
The default speed of GPT-6 Astra and GPT-6.1 Sol has increased by approximately 50%, with the target rising from 30 tokens per second to approximately 50 tokens per second.
According to Arena benchmark data, Argon's cost per task is approximately 33% lower than GPT-6.1 and approximately 70% lower than Claude Opus 5.5.
According to the tester, Astra's price is approximately 5 times more expensive than GPT-6.1.
