Weekstart Brief · Issue 6

Get your agent stack set straight before the week starts.

Weekstart is a weekly Monday brief for people who run AI agents in production. It covers the changes that break your agents or change their costs, with what to do about each one.

This week, in short:

A popular fast model was swapped for a different one behind the same name more than a week ago. Nothing errored, so your agents may have changed without you noticing.
A code host now rejects pushes that carry one kind of AI API key. Agents that commit test files can get stuck.
A new flagship model drops a caching feature many agents lean on, and its price doubles in seven weeks.
Two SDK upgrades quietly change when an agent stops and what it reports about itself.
A batch of older, cheap models that plenty of agents still run on got a shutdown date.
