What changed
DeepSeek keeps the deepseek-flash API alias, calling method and pricing unchanged.

Our analysis
Builder’s view: treat a stable alias as a moving dependency. Rerun fixed tool-call and structured-output cases, checking valid outputs, completed tasks and actual token use before widening rollout.
Keep in mind
The weights release omits a Jinja chat template; callers handle inference and tool execution. Vendor performance claims are untested here.
