GPT-6 Astra leads by 0.0 points.
Can it work through constraints and connect clues? LiveBench uses spatial, navigation, perspective-taking and logic-puzzle tasks. Useful for planning, but not a direct test of long-running agents.

Where their benchmark results differ
Coding
A tie in this snapshot.
Can it write or complete code that passes tests? These are contained programming problems, not entire software projects.
Agentic coding
GPT-6 Astra leads by 2.8 points.
Can it edit code in a tool-using workflow? LiveBench tests JavaScript, TypeScript and Python tasks. Results depend on the testing software and tools as well as the model.
Mathematics
GPT-6.1 Sol leads by 0.0 points.
Can it solve difficult quantitative problems with checkable answers? Strong math is useful evidence of reasoning, but does not guarantee better writing or tool use.
Data analysis
GPT-6 Astra leads by 0.3 points.
Can it join and reformat tables and reason about event sequences? Useful for agents that process structured business information.
Language
GPT-6.1 Sol leads by 0.7 points.
Can it interpret word relationships, reconstruct plots and correct typos? This is a narrow language test, not a full measure of writing quality or multilingual coverage.
Instruction following
GPT-6 Astra leads by 1.4 points.
Can it follow requested constraints while rewriting, simplifying, summarizing and composing text? Relevant to agents that must return a specific format.
How to choose between them
Start with your task, not the overall winner. Coding agents need a strong edit-and-test loop; research agents need structured information handling; support agents need instructions followed consistently. Our default weights are only one interpretation of those needs.
Both models are compared on LiveBench’s 25 June 2026 question set. The tested reasoning configurations differ where shown. More thinking can improve results while changing token use and response time. No speed advantage is inferred from these scores.
Cost assumptions
All prices are USD. The baseline uses 1,000 calls with 10,000 input tokens and 2,000 billed output tokens per call. Include reasoning tokens; caching, tools, retries and provider premiums are excluded. Change the workload and weights to see whether the tradeoff changes.
Evidence and uncertainty
Consensus combines LiveBench and Arena only when the model version and thinking setting match. A missing score does not mean a model is worse. Small differences may change with the tasks, settings or repeated runs; the combined rating does not tell us how certain a difference is.
