Broader cyber-model access patches more bugs, but doesn't prove open-sourcing frontier models is safe

Alex Barry weighs into the debate over who should get highly cyber-capable models: sol 5.6 daybreak access is much broader than the earlier Mythos Glasswright early-access group, and broader access did lead to more things being patched.
But he flags a key gap in the argument: "more people with access → more patching" is a totally different claim from "open-sourcing Mythos would've been fine." The latter hinges on what bad actors would do with that level of cyber capability relative to good actors — something the current evidence doesn't address. The thread context discusses why the early-access group didn't catch the vulnerability, suggesting capability diffusion and broader access matter far more than initially thought.
