Can I use Haiku for everyday Claude Code work?
Haiku 4.5 is fast and cheap (\$1 input / \$5 output per MTok, roughly a third of Sonnet 4.6 and a fifth of Opus 4.7), with near-frontier intelligence on scoped tasks. Use it for mechanical batch work, subagents, and latency-sensitive turns; do not reach for it on hard debugging or architecture, where Sonnet 4.6 still wins. The biggest pitfall is invisible: `/effort` levels and adaptive reasoning do not apply to Haiku.
