The cheap Claude, before there was a naming convention for cheap Claudes: Anthropic described it as carrying the strengths of Claude 2 into something faster and more affordable, which is where a great deal of unglamorous production traffic quietly went. Seven model IDs were switched off together on 6 November 2024 — the whole Claude 1 line, and the oldest entry in Anthropic's deprecation history.
