GPT-6.1 Terra ranks 8th in Agent Arena, with a median cost of $0.62 per task
Arena's empirical results, based on nearly 9,000 agent sessions, show that OpenAI's GPT-6.1 Terra (Max) ranks 8th in Agent Arena, with a net improvement of +10.6% and a median cost of $0.62 per task. This cost is 43% lower than the $1.09 of 7th-place Gemini 4 Argon (High), 30% lower than the $0.89 of 6th-place GPT-6.1 Sol (Max), and 88% lower than the $5.16 of 5th-place GPT-6 Astra (Max). In the subcategories, it ranks 3rd in Bash Reliability (+13.2%), 7th in Steerability (+13.3%), and 9th in Praise vs Complaint (+16.8%).

Body
Real-world results are in: GPT-6.1 Terra (Max) by @OpenAI ranks #8 in Agent Arena across nearly 9K agentic sessions from our global community of users.
With +10.6% net improvement and a median cost per task of $0.62, it has reshaped the Pareto frontier! See its placement in the thread. Its median cost per task is:
- 43% lower than Gemini 4 Argon (High) at #7 ($1.09) - 30% lower than GPT-6.1 Sol (Max) at #6 ($0.89) - 88% lower than GPT-6 Astra (Max) at #5 ($5.16)
By signal, its strengths include:
- #7 in Steerability (+13.3%): whether the model can course-correct when you push back - #3 in Bash Reliability (+13.2%): whether its commands succeed, excluding errors outside its control - #9 in Praise vs Complaint (+16.8%): implicit sentiment in users’ reactions
Congrats again to the @OpenAI team on this release!
