Anthropic launched its new Haiku 4.5 model.
The small model is faster and more cost-effective.
Haiku 4.5 is available for all Claude.ai free plans.
While large language models (LLMs) are what we most commonly associate with generative AI products, such as chatbots, small language models (SLMs) have their own perks, including lower costs and higher speeds. Leaning into these advantages, Anthropic is now launching a new small model: Haiku 4.5.
