Mistral AI Mistral Large 3 VS xAI Grok 4.5
⚖️Our Take
These models use different coding evaluation benchmarks — with Mistral Large 3 evaluated on live-code-bench (good at single-file apps, building games & UIs, and scripting new logic) and Grok 4.5 on swe-bench-pro (excellent at multi-file repositories, autonomous agents, and industrial codebases) — but Grok 4.5 holds a clear reasoning advantage (+7.5% on GPQA Diamond). However, Mistral Large 3 is a massive 4.0x cheaper to run. Choose Grok 4.5 for complex logic and reasoning tasks, or Mistral Large 3 to optimize your budget for high-volume pipelines.
