On July 1st, Beijing time, Anthropic, a prominent U.S. AI model firm, introduced its latest mid-range flagship model, Claude Sonnet 5. This model showcases robust agent execution abilities, allowing it to tackle intricate tasks like web browsing, code creation, and multi-phase planning. Its performance nearly matches that of the premier model, Opus 4.8, yet comes at a more affordable price point. Concurrently, Anthropic officially acknowledged receiving notice from the U.S. Department of Commerce, announcing the formal removal of restrictions on its high-end flagship models, Claude Fable 5 and Mythos 5. Both models will be fully accessible worldwide starting from tomorrow.
