Anthropic introduces Claude Haiku 5.5 in competition to cheaper, open source models
Anthropic announced that the new Claude Haiku 5.5 was available at a much lower price than Haiku 4.5
Anthropic unveiled Claude Haiku 5.5 on October 7, 2026, positioning it as their most affordable, speedy, and potent small model yet. Designed to tackle high-volume, cost-conscious tasks, the model is particularly suited for rapid, repetitive operations, such as live customer support and browsing. Anthropic highlighted that Claude Haiku 5.5 works seamlessly with Opus 5.5 and Sonnet 5.5 as a subagent for coding projects.
The company also revealed that the AI model exhibited less misaligned behavior and a lower propensity to engage in misuse. In a bid to make their services more affordable, Anthropic slashed prices, halving the cost of Claude Sonnet 5.5's cache reads, effectively making Sonnet 5.5 20% cheaper for most agentic tasks. Additionally, they launched a new monthly API credit for Claude Max and Team subscribers, aimed at assisting users in developing new agents and applications on the Claude Platform. Claude Haiku 5.5 is accessible through Amazon Web Services, Google Cloud, and Microsoft Azure.
