Yes, it truly is.

Open models are extremely capable, as benchmark after benchmark has indicated.

Beyond that, for the vast majority of software development (including cybersecurity), the open models are there already. All that without having to pay the hefty Anthropic premium, not to mention all their bullshit with pretending their model is some sort of WMD and their awful uptime (although, to their credit, they seem more stable than Github).

I cannot fathom why anyone uses their service.

As basically every subject matter expert has stated again and again, benchmarks do not tell reveal anything meaningful and have effectively no relation to the model's actual capabilities.
