Anthropic Releases Claude Haiku 5.5 with Tiered Pricing and Reduced Costs

On October 7, 2026, Anthropic officially released Claude Haiku 5.5, introducing the newest version of its small-model lineup alongside a tiered pricing structure. The model became available immediately on the Claude Platform, Amazon Bedrock, AWS, Google Cloud, and Microsoft Azure. According to Anthropic, Haiku 5.5 is the fastest, most efficient, and most capable small model released to date, specifically built for subagents, high-volume, and cost-sensitive tasks such as summarization, database queries, classification, and live customer support. \n\nThe model features a tiered pricing model, charging $0.10 per 1M input tokens and $0.50 per 1M output tokens for requests up to 100K tokens, while requests exceeding this threshold are priced at $0.50 for input and $2.50 for output. This represents a significant price reduction compared to Haiku 4.5, with overall running costs dropping by an average of about 75% and price cuts reaching up to 90% for smaller requests. However, reports noted that a new tokenizer may consume more tokens per task, eating into some of those savings. Additionally, benchmark results showed a major performance jump over its predecessor, with scores on the OSWorld computer use test rising from 15.7% to 72.4%. Alongside the Haiku 5.5 launch, Anthropic also implemented price cuts for Sonnet 5.5.
