What to check when moving from Opus 4.8

For most configurations, you can replace claude-opus-4-8 with claude-opus-5. Review these two behavior changes:

Thinking is enabled by default. If effort is set to xhigh or max, disabling thinking returns a 400 error.
max_tokens covers thinking and visible output. Leave enough headroom for tasks that require long reasoning and a large final response.
