Anthropic has released Claude Fable 5.1, featuring a 75% reduction in cache price to make persistent agents more economical. This release is accompanied by a new security architecture called Enterprise Frontier Safeguards. Google has responded by launching Gemini 3.8 Flash at a competitive introductory price.
“Anthropic is simultaneously changing the economics of running persistent agents, reducing the cost of cached context by 75% and introducing a new security architecture called Enterprise Frontier Safeguards or EFS, designed to let organizations retain monitoring data inside infrastructure they control.”
“Google countered with Gemini 3.8 Flash.”
“Google's Gemini 3.8 Flash currently lists at 75 cents per million input and $3.75 per million output through the end of 2026.”
