Claude 3.7 Sonnet has emerged as a groundbreaking advancement in natural language processing and reasoning capabilities. Released as Anthropic's most intelligent model to date, it represents the first hybrid reasoning model on the market, capable of both near-instant responses and extended, step-by-step thinking that's visible to users. However, recent changes to Anthropic's access policy have placed this powerful tool behind a paywall for direct access through Claude.ai. Is this temporary or permanent? No one can be sure about that.
