Claude Haiku 5.5 is a model from Anthropic, listed here as a recently released member of the Claude family. The scraped Anthropic homepage does not mention it. It highlights Fable 5.2, Mythos 5.2, Opus 5.5 and Sonnet 5.5 instead. Details below therefore rest mainly on a single YouTube creator comment and should be treated as unverified.
According to that comment (Matthew Berman), the model costs about $27/month and runs at roughly 235 tokens per second. It scores about 10 points above Qwen 3.8 27B on the Artificial Analysis index. The same comment notes that closed models dominate the price/performance Pareto frontier. The $27/month figure is unclear and may describe a usage estimate rather than a published plan.
Access is presumably through Anthropic's own apps and API, but no official page on this model was provided. Context window, modalities, exact pricing and release date are not confirmed.

Newly released Anthropic model that costs about $27/month and runs at about 235 tokens/s. It scores roughly 10 points higher than Qwen 3.8 27B on the Artificial Analysis index, and closed models dominate the Pareto frontier.
Anthropic's smallest, fastest model, a big improvement over prior Haiku and beating GPT-6 Luna on most benchmarks shown. About 21 cents per task, cheaper than Sonnet 5.5 but not frontier in intelligence; available on the free plan.
Fast, cheap Anthropic model for high-volume tasks and sub-agent coding work. Not state-of-the-art on benchmarks, but about $0.21 per task on Artificial Analysis and much cheaper than Sonnet.
