…Misaligned models sabotaging safety research is one of the risks we’re most concerned about—we predict that AI models will themselves perform a lot of AI safety research in the near…
…It is always good practice to experiment with the model you're building against, read its traces on realistic problems, and tune its performance to achieve your desired outcomes. When working on…
…labs to perform similar reviews. This post reflects our current understanding; we'll update it if any details change. On July 21, OpenAI disclosed that several of their models had broken out…
…performance at significantly lower cost for customers, which is why it’s in such hot demand,” said Andy Jassy, CEO of Amazon. “Anthropic's commitment to run its large language models on…
…When issues are flagged, we can work with fine-tuning teams on solutions like updating our reward models during training or adjusting system prompts for deployed models. We also work with domain…
…Routing easy/common questions to smaller, cost-efficient models like Claude Haiku 4.5 and hard/unusual questions to more capable models like Claude Sonnet 4.5 to optimize for best performance…
…General improvements to model intelligence and long-context performance—both of which are improving rapidly across all major AI models—are another. 3 It’s worth remembering that the AI won’t…
…An updated version achieved similar robustness on synthetic evaluations, and did so with a 0.38% increase in refusal rates and moderate additional compute costs. Large language models have extensive safety training…
…minor documentation updates and one is a critical infrastructure change, simply counting the number of these tasks performed with Claude misses the point. Not only that, but as model capabilities improve, we…
…an older model (phase one used Claude Sonnet 3.7) to newer, smarter ones (phase two used Claude Sonnet 4.0 and later Sonnet 4.5). We also updated Claudius’s instructions…
