A guide proposing 12 principles for building reliable LLM-powered agent applications, inspired by the 12 Factor Apps methodology. The author argues that production agents should be mostly deterministic software with LLM reasoning at key points, and introduces a framework covering factors like prompt ownership, context management, execution state, and control flow.
General Motors introduced a new 6.6-liter Gen 6 small block V-8 engine for the 2027 Chevrolet Silverado 1500 and GMC Sierra 1500, producing 481 horsepower and 501 pound-feet of torque—making it the most powerful naturally aspirated pickup engine. The engine features increased displacement, a higher 12.5:1 compression ratio, a new dual fuel injection system combining direct and port injection, and a completely redesigned oiling system addressing reliability issues from the previous 6.2-liter engine.
