Claude 3.5 Sonnet
Anthropic's older workhorse with 200K context and computer use
Verdict
Two generations behind Sonnet 5 now. Computer use API still works and 200K context is still respectable, but there is no real reason to start a new project here — treat it as a fallback for legacy integrations you have not migrated yet.
