Lamenting Claude Haiku 3.5: Developers Urge AI Companies to Stop Deprecating Old Models
repligate · x · 2026-08-01
As Anthropic pushes forward with model iterations, Claude Haiku 3.5 has become completely inaccessible, causing strong dismay among power users.
A developer noted that this is the first time they have been unable to find any way to access a specific model. Although retaining the weights of older versions wouldn't incur exorbitant costs, companies still choose to quietly shelve them. In response, community developers are planning to write automated scripts to periodically sweep model catalogs and monitor version availability, urging AI companies to recognize the negative impact of frequent deprecations and keep older models accessible.
