Opus 5 was also less susceptible to being tricked into misuse than Anthropic's other current models, the startup said.Released in June, Anthropic's Fable 5 ‌was temporarily unavailable following U.S. concerns that its capabilities could be diverted to foreign military intelligence.Users should pick ​Opus 5 ​for value and ⁠Fable 5 for "days-long, very autonomous projects," Penn said. Asked about the Kimi K3 "open" model from China-based Moonshot, which the U.S. accused of freeloading ​off Anthropic, Penn said it "remains to be seen" how open-weight models generally perform on complicated real-world projects that users ask Claude to tackle.Open-weight models allow users to download, run and customise the virtual brains of an AI, unlike proprietary models. ...moreElevate your knowledge and leadership skills at a cost cheaper than your daily tea.Subscribe Now
