Grok 4.5 Tops Legal Benchmark, Beating GPT-5.6 in Speed and Quality
XFreeze · x · 2026-08-02
In Legora’s benchmark for real-world legal work, Grok 4.5 hits the Pareto frontier for both speed and quality, outperforming GPT-5.6 Sol and Claude Opus 4.8.
- Speed Leader: Across seven frontier models, Grok 4.5 delivered the fastest median time per case.
- Quality Threshold: It was the only model positioned inside Legora’s “best” zone for both metrics.
- Competitor Performance: OpenAI’s GPT-5.6 Sol was slower and fell below the benchmark’s average quality. This proves that frontier intelligence does not need to sit there thinking forever to deliver high-quality professional work.
