Browser-use benchmark: MiniMax M3.1 Flash ties Sonnet but still isn't recommended

The author ran a computer/browser-use benchmark in Runable and found MiniMax M3.1 Flash scored exactly the same as the Anthropic model — which even failed one task — yet the tool still ranked Anthropic higher, raising bias concerns.

When you do any kind of testing with Anthropic models, it almost always find out ways to tell that anthropic is the best, I am not sure i can trust Anthropic models now. In a computer/browser use bench we use for Runable MiniMax M3.1 Flash scored exactly the same but still its not recommending it. Sonnet actually failed at one task but still somehow its better.
