OpenAI的GPT-5.6 Sol在Agent Arena上冲到第二，比前代进步明显，和Claude Fable 5差距缩小了，想看看真实任务中模型表现的话值得关注。
GPT-5.6 Sol在Agent Arena排行榜上以7800次真实世界智能体会话位列第二。相比GPT-5.5 (xHigh)净提升1.6%。与榜首Claude Fable 5的差距主要来自“表扬 vs 投诉”信号，后者得分+17.3%，GPT-5.6 Sol为+10.9%。Agent Arena基于数百万真实世界长周期任务，使用因果追踪方法评估。GPT-5.6系列（Sol, Terra, Luna）已开始在ChatGPT、Codex和API中推出。

GPT-5.6 Sol by @OpenAI is #2 on the Agent Arena leaderboard, based on 7.8K real-world agentic sessions! It is a notable uplift from GPT-5.5 (xHigh) of +1.6% Net Improvement, narrowing the gap with the frontier Claude Fable 5. The biggest difference comes from ‘Praise vs Complaint’, a signal that captures implicit user satisfaction with an agent’s responses and artifacts. Claude Fable 5 scores +17.3%, compared with +10.9% for GPT-5.6 Sol. See detailed signal-level comparison below. In Agent Arena, we measure models on millions of real-world, long-horizon agentic tasks from a global community of users. Models can access web search, filesystem, and terminal tools to complete complex workflows. The leaderboard measures model performance on outcomes relative to the average model using a causal tracing methodology. Congrats again to the @OpenAI team! OpenAI @OpenAI Sol, Terra, and Luna, our GPT‑5.6 family of models, are starting to roll out now in ChatGPT, Codex, and the API.
