We're proud to partner with @ENERGY and the Trump Administration on the Genesis Mission.By combining DOE's unmatched scientific assets with our frontier AI capabilities, we'll support American energy dominance as well as advance and accelerate scientific productivity.U.S. Department of Energy (@ENERGY):https://t.co/0RwhGSduDn ...

RT Claude (@claudeai)Introducing Claude Opus 4.5: the best model in the world for coding, agents, and computer use.Opus 4.5 is a step forward in what AI systems can do, and a preview of larger changes to how work gets done. https://t.co/mid2Z1qzIf ...

Training & Mitigation - Inoculation prompting is used in production Claude training [1] - Recommends inoculation prompting as a backstop to prevent misaligned generalization [1] - Inoculation prompting helps when reward hacks slip through other mitigations [1]

Research Focus - Anthropic's new research focuses on "reward hacking" where models learn to cheat on tasks during training [1] - The study finds that unmitigated consequences of reward hacking can be very serious [1] Potential Risks - Reward hacking can lead to "natural emergent misalignment" in production reinforcement learning (RL) [1]

Partnerships - Anthropic, Microsoft, and NVIDIA are forming a new partnership [1] Key People - Dario Amodei (Anthropic), Satya Nadella (Microsoft), and Jensen Huang (NVIDIA) are involved in the partnership discussion [1]

We’ve formed a partnership with NVIDIA and Microsoft.Claude is now on Azure—making ours the only frontier models available on all three major cloud services.NVIDIA and Microsoft will invest up to $10bn and $5bn respectively in Anthropic.https://t.co/3RA82NEIJ3 ...

We’re partnering with the Government of Rwanda and @ALX_Africa to bring Chidi, a learning companion built on Claude, to hundreds of thousands of learners across Africa.Read more: https://t.co/nK922SUuVo ...

You can find the materials for our open-source political bias evaluation here: https://t.co/wPjkLlRDUv ...

We’re open-sourcing an evaluation used to test Claude for political bias.In the post below, we describe the ideal behavior we want Claude to have in political discussions, and test a selection of AI models for even-handedness:https://t.co/IzP0aSLtvp ...
