Anthropic has extended the billing deadline for its FAB 5 model, which is now set for July 19th. Despite FAB 5's strong performance in coding and aggregate quality benchmarks, its token pricing is significantly higher than competitors like GPT-5.6 Sol and Grok 4.5. GPT-5.6 Sol, in particular, offers competitive capabilities at roughly half the cost of FAB 5, putting pricing pressure on Anthropic.
