Anthropic may not have intended to write an excellent ad for GLM 5.3, but that's what they did.

Unlike Mythos, I might actually have a chance at using GLM for defensive research. Anthropic didn't reply to any of my requests for Mythos access for use on OpenSSH.

GLM-5.3 and the spread of advanced cyber capabilities
GLM-5.3 can autonomously build end-to-end cyber exploits, but unlike other frontier models, it was released without meaningful safeguards to limit misuse.
![Abstract. We initiate the study of basing the hardness of hinted ISIS problems (i.e. with trapdoor information, or ‘hints’) on the previously conjectured space-time hardness of lattice problems without hints. We present two main results.
1. If there exists an efficient algorithm for hinted ISIS that outputs solutions a constant factor longer than the hints, then there exists a single-exponential time and polynomial memory zero-centred spherical Gaussian sampler solving hinted SIS with norm a constant factor shorter than the hints.
2. Assume the existence of a chain of algorithms for hinted ISIS each taking as input Gaussian hints whose norms decrease by a constant factor at each step in the chain, then there exists a single-exponential time and polynomial memory algorithm for SIS with norm a quasilinear factor from optimal.
The existence of such hinted ISIS solvers implies single-exponential time and polynomial memory algorithms for worst-case lattice problems, contradicting a conjecture by Lombardi and Vaikuntanathan (CRYPTO’20) and all known algorithms. This suggests that hinted ISIS is hard.
Apart from advancing our understanding of hinted lattice problems, an immediate consequence is that signing the same message twice in GPV-style [Gentry–Peikert–Vaikuntanathan, STOC’08] schemes (without salting or derandomisation) likely does not compromise unforgeability. Also, cryptanalytic attempts on the One-More-ISIS problem [Agrawal–Kirshanova–Stehlé-Yadav, CCS’22] likely will need to overcome the conjectured space-time hardness of lattices.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:fwa55bujvdrwlwlwgqmmxmuf/bafkreib5oxxsmuh3zvn7oz6c2bhusztjf5oyp4aqzn7w7m6kpbphrokiou)
