[AINews] Claude Haiku 5.5 — better than GPT-6 Luna at the same pricing
· Source: Latent Space
Anthropic has released Claude Haiku 5.5, the first update to the Haiku line in about a year. The model launches at a price comparable to OpenAI’s GPT‑6 Luna, while the company simultaneously lowered the rates for Sonnet 5.5. Haiku 5.5 incorporates new effort tuning and an adaptive reasoning mechanism, enabling it to act as a specialized sub‑agent for high‑volume, low‑cost tasks such as summarization, text compression, or database queries, working alongside the more powerful Opus 5.5 or Sonnet 5.5 models.
The model is available on both the Claude platform and Claude Code, with a two‑tier pricing structure based on prompt length. Fees range from $0.10 to $0.50 per million input tokens and from $0.01 to $0.05 per million output tokens. Anthropic has also added monthly API credits for subscribers, expanding usage limits and easing integration with third‑party tools. In independent tests, Haiku 5.5 scored 43 on the Artificial Analysis Intelligence Index, beating models such as GLM‑5.3 Flash and Gemini 3.8 Flash, though it remains behind Sonnet 5.5.
This news is significant because it demonstrates how competition in smaller‑scale AI models is advancing in capability and efficiency, offering more affordable options for high‑volume applications and driving wider AI adoption in business and development settings.
