CERT-In gets access to Anthropic's unreleased Mythos model for cyber defence testing
India's CERT-In has been given access to Mythos, an unreleased Anthropic model, for cyber defence testing, according to reporting on the arrangement.

CERT-In is India's national computer emergency response team. It has been given access to Mythos, an Anthropic model that has not been released publicly. The arrangement is for cyber defence testing, according to reporting on the deal.
The access matters because a government security body gets an unreleased model before general release. What that changes for defenders, and for Anthropic's release plans, is not yet clear. Neither side has said how long the access lasts or what testing it covers.
Mythos is described as unreleased. The public cannot use it, and outside researchers cannot inspect it. CERT-In handles computer security incidents in India. Testing a model in that setting is different from a commercial rollout. The reporting does not say whether other agencies have similar access. It also does not say whether the testing feeds back into the model's development.
"The arrangement gives CERT-In access to Mythos for cyber defence testing," the reporting says.
Anthropic has not announced a public release date for Mythos. The terms of the access, including any restrictions on how the model is used, have not been disclosed.
