  “Anthropic is helping the US National Security Agency deploy its powerful Mythos AI model for offensive cyber operations” not totally surprising but still a pretty major escalation https://www.ft.com/...

  Worth remembering that only a few weeks ago Anthropic was citing China's use of AI to “hack governments and corporations across the world” as a reason to thwart its AI R&D capacity. Now they are reportedly helping an agency that does exactly that. https://www.anthropic.com/...

  Our internal data shows Claude is accelerating AI development—a possible path to recursive self-improvement, or AI autonomously building a more capable successor. It's happening faster than we thought, and the implications deserve greater attention. https://www.anthropic.com/...

• @alexalbert__ Alex Albert on x

  We just published internal data on how much of Claude's development is already being done by Claude: - Over 80% of all code merged into our codebase is now written by Claude - It's been months since many researchers at Anthropic hand-wrote code - The typical Anthropic engineer sh…

  Each time we release a model, we run the same test: give it code that trains a small AI model, ask the new model to speed it up. It takes a skilled human 4-8 hours to reach 4x faster. In May 2024, Claude Opus 4 averaged a ~3x speedup. This April, Mythos Preview achieved ~52x.

• @anthropicai @anthropicai on x

  None of this guarantees recursive self-improvement is on the horizon. It's not yet clear that Claude is capable of research judgment—of choosing the right problems to work on. But if these trends continue, AI systems designing and building their own successors is plausible. This

• @anthropicai @anthropicai on x

  AI research is a series of next-step decisions. We looked at sessions where a human researcher took a wrong turn, showed Claude the session up to that point, and asked it what to do next. Mythos Preview improved on humans 64% of the time—up from 22% in 2024. [image]

  Kudos to Anthropic for writing about this! I'm confused that even in their most aggressive scenarios humans still “play a substantially diminished role in [AI] development.” Does Anthropic really think that humans will stay relevant indefinitely? [image]

• @_sholtodouglas Sholto Douglas on x

  Programming has already changed dramatically. On my best days - I literally feel IO bandwidth limited managing the concurrent threads. As the models get better the level of abstraction will keep going up - very soon the models will only come to us for hard calls. Eventually -

  The speedup isn't just in volume. On open-ended coding problems where answers are unclear, Claude's success rate is now 76%—a 50 point jump in just 6 months. Many engineers also say Claude's code quality is now on par with human code; we expect it to be better within the year. [i…
