Key takeaways
Opus stays anchored around the $15/$75 input/output rate — Anthropic prices the flagship for top-tier quality, not for sheer volume.
Sonnet absorbed Opus 3-level quality over 2024–2026 with no list-price move, making it the workhorse for most production traffic.
Haiku trended down as small-model demand grew. Combined with 50% Batch API discount and 10% cache-read, effective input on Haiku falls below $0.05 per million for many extraction workloads.
