Working on RL for long-horizon SWE tasks has been both fun and challenging. And it’s incredibly rewarding to see our model demonstrate great generalization across multiple benchmarks in different settings. 🚀
Grok 4.5 ranks #2 on FrontierSWE It is only outperformed by Claude Fable 5 and ranks higher than Opus 4.8, GPT-5.5 and GLM-5.2
Grok 4.5 is worth trying
Grok 4.5 just ranked #2 on the FrontierSWE leaderboard, outperforming Claude Opus 4.8 and GPT-5.5 It delivers top-tier coding performance with exceptional speed, strong token efficiency and a much lower cost than many competing frontier models Grok 4.5 is already one of the best coding models available today, sitting at the very top
