Grok 4.5 sits on the Pareto frontier of Legora’s benchmark for real-world legal work, outperforming GPT-5.6 Sol and Claude Opus 4.8 on both speed and quality
Across seven frontier models, Grok delivered the fastest median time per case while still producing high-quality, above-average legal work
It was the only model positioned inside Legora’s “best” zone for both speed and quality
OpenAI’s GPT-5.6 Sol was slower and fell below the benchmark’s average quality in this evaluation
Grok 4.5 proves that frontier intelligence does not need to sit there thinking forever
High-quality professional work, delivered at real-world speed
