Anthropic Criticized for Neglecting Small Models as Haiku Lags Behind OpenAI
kimmonismus · x · 2026-08-09
A user pointed out that Anthropic's small model, Haiku 4.5, hasn't been updated in almost 12 months. In contrast, OpenAI has found outstanding solutions and use cases for its small models, such as Luna.
The critique suggests Anthropic is ignoring its small model lineup, speculating that Sonnet might effectively become the new "Haiku" moving forward.
