Agent swarm spends $3M/month in tokens to build game Spawn, treats an hour without shipping as SEV-0

Simon Willison highlights Jacob Sansbury's writeup on Spawn, a multiplayer game world built autonomously by a swarm of Fable-powered agents costing over $3M/month in tokens (30x payroll). Agents change live code and ship hourly, 60% of work starts from production errors or bug reports filed by the in-game agent Savi, and an hour without a release is treated as a SEV-0 incident. Willison demoed it by prompting a castle and a dragon into existence on his phone.
