# The Race to Make Agents Cheap Enough to Actually Ship

Anthropic shipped Claude Sonnet 5 today with an unusually transparent cost-performance breakdown — a signal that the real competition in AI has shifted from capability to economic viability in production. But a parallel wave of reliability research is finding that the failure modes most dangerous in autonomous, looping agents are exactly the ones current benchmarks don't catch.
