So far, scores look mostly consistent before and after re-deployment. Fable 5 remains at the frontier across Text, Document, Vision, and Code Arena: Frontend. The ~20-point drop in Frontend is still within the confidence interval as scores continue to stabilize. We’ll share more insights as more data comes in across all arenas - stay tuned! Arena.ai @arena Fable 5 is back in the Arena! When it first debuted, Fable 5 ranked #1 in Agent Arena: our benchmark for real-world, long-horizon agentic performance. Agent Arena evaluates models on millions of real tasks submitted by a global community of users, with access to web search, filesystem, and terminal tools to complete complex workflows. Rather than raw win rates, the leaderboard uses causal tracing to measure how much each model's outcomes outperform the average model. @AnthropicAI 's latest model is also live in Text, Vision, Document, and Code Arena: Frontend. Come give it a try in Battle Mode and Agent Mode and contribute to the leaderboards. 🔗 View Quoted Tweet 💬 1 🔄 0 ❤️ 2 👀 1106 📊 1 ⚡
