Ask HN: Which frontier model can do code security reviews

The user is seeking a frontier model for code security reviews, as their current model, Opus 5.5, is insufficient for this task. Opus 5.5 has been able to identify some security issues, including a race condition in haproxy, but its capabilities are limited. The user's attempts to upgrade to a more advanced model, Mythos, have been unsuccessful due to a required verification program that they are not permitted to complete. The user is looking for alternative frontier models that can perform extensive code security reviews. They mention that uncensored Qwen forks may be an option, but are seeking other possibilities. The user's goal is to find a model that can effectively conduct code security reviews without the limitations of Opus 5.5.
