Agent leaderboards score the solved task, wherever the lab is based. These are the numbers, with each lab's country.
| Model or system | Lab | Country | Score |
|---|---|---|---|
| Rogue Constellation | Rogue | Brazil | 71.21% |
| Claude Opus 5.5 | Anthropic | United States | 66.4% |
| GPT-6 Astra | OpenAI | United States | 57.9% |
| Gemini 4 Argon | United States | 57.4% |
Pass rate on Terminal-Bench 4.0 as published by each lab. On the official leaderboard (tbench.ai, checked November 6, 2026), the leader is Claude Code with Opus 5.5 at 64.8%. Rogue ran all 66 tasks, with a standard error of about 5.5 points. Read the research

| DeepSeek V4 Pro | DeepSeek | China | 62.83% |
| Qwen 3.8 Max | Alibaba | China | 57.46% |
Best result per lab on the public DeepSWE v1.1 leaderboard (Datacurve, September 22, 2026) and Rogue's internal evaluation. DeepThink Preview builds on GLM 5.3. Off the leaderboard, Meta reports 75.4% for Muse Spark 1.3 and Anthropic 74.2% for Claude Opus 5.5. Read the research
Cost counts too
A high score at any price is not useful every day. In the effort router study, running GPT-6 Astra at max effort on every task cost 69% more than the router for a score only 0.3% higher. The router matched high effort at 15% lower cost.
That is why every Rogue study publishes the cost per task next to the score.
Where to use it
In the browser, at app.rogueon.ai, to build and publish web apps and websites. On a Mac, with Rogue Code, which works in a folder on your computer and shows files and a preview beside the conversation. Rogue Code downloads by invitation, with a waitlist.
Questions
Which benchmark should I use to compare coding AIs?
Agent benchmarks that run the task in a real environment and check the result, such as Terminal-Bench and DeepSWE. OpenAI stopped reporting SWE-bench Verified in February 2026.
What is Rogue Code?
It is Rogue's Mac app. You speak or type a request, and Rogue builds and revises the project in a folder on your computer.
What is Rogue Constellation?
It is Rogue's most advanced coding agent. It puts five agents on every task and returns the solution with the strongest evidence that it works.
