Anthropic released Claude Haiku 5.5.
What happened
According to Latent Space reviewers (AINews), the model outperforms OpenAI’s GPT-6 Luna at the same price.
For executives, the takeaway is that the entry-level model has become a workhorse for business processes and should be chosen based on time to outcome.
A place on the leaderboard offers little for this solution
Haiku 4.5 was released about a year ago. Since then, Anthropic released Sonnet, Opus, and Fable up to version 5.5, while its entry-level line seemed forgotten. During that time, OpenAI introduced Luna 6 along with Astra and Sol 6. Haiku 5.5 restored Anthropic's competitive position in the lower, largest segment. The comparison has one limitation.
This conclusion comes from an AINews review that rated the model better than Luna 6 at the same price.
