+  - 💰 **75% cost reduction** - $0.10/MTok input vs $0.15/MTok for 4o-mini
+  - 🧠 **Maintained quality** - 80.1% MMLU benchmark score
+  - 📄 **1M token context** - handles massive diffs effortlessly
+
+- **Anthropic**: Updated default from `claude-3-haiku-20240307` to `claude-3-5-haiku-20241022`
+  - ⚡ **Fastest Claude model** - "intelligence at blazing speeds"
+  - 🎯 **Superior performance** - surpasses Claude 3 Opus on many benchmarks
+  - 📅 **Recent training data** - July 2024 vs August 2023 cutoff
+  - 🔧 **Enhanced tool use** - more reliable structured outputs
