It's not necessarily true. OP has not provided actual objective figures. The nuance is in tokens spent per successful completion. So sure, you can blast DeepSeek for 1 hour solving a hard task, or Opus-5 for 5 minutes on the same task. Opus would ultimately be cheaper because time IS money and solving things faster is ultimately cheaper. Sure, benchmarks will show cost to be lower but people who test all of these models in real world use cases know the benchmarks are not reflective of real world use cases and Chinese models choke on problems Fable or gpt-sol will breeze through.
