Anthropic has released its new model, Fable 5.1, which specializes in programming and scientific tasks, maintaining the same pricing as its predecessor. However, the company has moderately reduced user costs for retrieving previously processed information (cache reads), with cache read prices dropping by 75%. According to Anthropic's estimates, the overall cost for typical workloads is reduced by approximately 25% compared to Fable 5, with costs for complex coding and highly agentic tasks potentially decreasing by up to 45%.
