DeepSeek V4.1 Flash hits Pareto frontier on 60 browser-use tasks at 50x lower agent cost

RT from gregpr07: a benchmark of 60 brutal browser-use tasks puts DeepSeek V4.1 Flash on the Pareto frontier of cost vs performance.
- Recorded agent cost is 50x lower than Sol and Opus at similar performance
- Running the entire dataset costs less than a single Sol task
If the numbers hold up, this dramatically lowers the barrier to scaling browser agents. (Third-party benchmark; methodology unverified.)
