claude-3-haiku-20240307 — pricing, context window and limits

Already past its published retirement date

This model's retirement date has already passed, and we did not re-verify whether the id still resolves at all as of this site's last check. If you're still calling it and it's still working, treat that as a temporary state rather than a stable one — nothing about a retired id continuing to function today is a guarantee it continues to function tomorrow.

The oldest naming convention still in this lineup

Unlike every other model on this site, this id carries an explicit date suffix rather than the short, generation-based naming the rest of the current lineup uses — a naming convention this site does not construct or extend, and one worth recognising on sight as a signal of just how old this particular id is relative to everything else covered here.

Cache and pricing figures, for reference only

The minimum cacheable prefix and pricing shown here are retained for reference and are not used by any calculator on this site — this id is excluded from every tool that prices current or legacy models, since it should not be the basis for any new budgeting decision.
