Drew Breunig(@dbreunig):For agentic coding, Fable and GLM 5.2 are best considered as the same story. Fable set the upper bounds at a price high enough to force every org to invest in systems to limit or mitigate costs. GLM 5.2 arrived just in time to help enable those systems and take over the work not worthy of Fable (which most of it). Investment will shift to harnesses, process design, and routing. The BIG question for the frontier labs: is the model used for coordination a Fable-level model…or is Fable a “planning” worker coordinated by something else…
