Anthropic, the US-based AI giant, released its latest Claude Sonnet 5 AI model on Tuesday. Anthropic claims that Claude Sonnet 5 delivers enhanced agentic search performance over the Sonnet 4.6 AI model. Meanwhile, it offers other agentic capabilities on par with the Opus 4.8 model, at lower costs. In terms of agentic coding, Sonnet 5 scored 63.2 percent on SWE-bench Pro, higher than Sonnet 4.6’s 58.1 percent score, but lower than Opus 4.8’s 69.2 percent score. Anthropic has also announced that the US government has removed export controls on the company’s Claude Mythos 5 and Fable 5 AI models. This comes weeks after the US administration restricted the AI giant from making its most capable cybersecurity-trained Mythos 5 and the “Mythos-class” Fable 5 models available to foreign nationals.
