Palantir published marketing material for their offering of AI for defense purposes. There's a video of how a military commander could order a military strike on an enemy tank with the help of LLMs.
One of the features that Palantir advertises is:
Agents
Define LLM agents to pursue specific, scoped goals.
Given military secrecy we are hearing less about Palantir's technology than we hear about OpenAI, Google, Microsoft and Facebook but Palantir is one player and likely an important one.
I would expect that most actual progress in weaponizing AI would not be openly shared.
However, the existing documentation should provide some grounding for talking points. Palantir talking about how the system is configured to protect the privacy of the medical data of the soldiers is an interesting view of how they see "safe AI".
