- @browser_useXKimi K3.1 Pro is a beast at browser use 🤯 76.8 on the Browser Use Benchmark. Only GPT-6.1 Sol scores higher. It beats Opus 5.5, Grok 4.7 and Sonnet 5.5, and it's cheaper than Opus at ~$2/task. Best Chinese model we've ever tested, by a lot. Next best is DeepSeek V4.1 Flash at 70.6. Moonshot cooked.View original ·
