I don't know what the solution to this is, but I find it somewhat unfair that I pay money to Anthropic, and I pay money to OpenAI, and neither of them will let me use their best models for securing the software I work on. Admittedly Opus 4.8 xhigh does a good job, but are my customers not entitled to have more security from a Fable/Mythos or GPT-5.5-Cyber audit over the codebase? Or I guess the inverse question: why…
They didn't test Opus 4.8, but it probably isn't very far behind.
