Anthropic 发布最先进 AI 模型 Claude Fable 5 和 Mythos 5
英文摘要
Anthropic launched Claude Fable 5, a Mythos-class 1 model, claiming state-of-the-art performance on nearly all tested benchmarks with exceptional capabilities in software engineering, knowledge work, vision, and scientific research. Fable 5 is safe for general use but conservative safeguards block some harmless requests in under 5% of sessions. The company also released Claude Mythos 5, identical to Fable 5 but with lifted safeguards in specific areas, initially deployed through Project Glasswing in collaboration with the US government for cyberdefenders and infrastructure providers. Mythos 5 is described as having the strongest cybersecurity capabilities of any model. Anthropic plans to expand Mythos 5 access via a trusted access program.
