Claude Haiku 5.5 发布并大幅降价，证明 AI 价格战远未结束

Anthropic has released Claude Haiku 5.5, its fastest and most affordable small model, built for high-volume tasks like data queries and customer support. Haiku 5.5 shows major benchmark gains over Haiku 4.5 at up to 90 percent lower token prices. It also beats OpenAI's budget model GPT-6 Luna in areas like agentic coding. Haiku 5.5 is available now on AWS, Google Cloud, and Azure. Anthropic is also cutting Sonnet 5.5 cache read costs in half and rolling out monthly API credits for subscribers. Anthropic has released Claude Haiku 5.5, the company's fastest and most affordable small model to date. Benchmark results show a major performance jump over its predecessor, and Anthropic is also cutting prices for Sonnet 5.5. Haiku 5.5 is designed for high-volume, cost-sensitive tasks like summarization, database queries, classification, and live customer support, according to Anthropic. On average, the model costs about 75 percent less than Haiku 4.5. For requests with prompts up to 100,000 tokens, which Anthropic says account for roughly 90 percent of all previous Haiku requests, prices drop by up to 90 percent. Prompts longer than 100,000 tokens cost five times as much. Anthropic points out that Haiku 5.5 uses an updated tokenizer that consumes slightly more tokens per task than its predecessor. The same thing happened with the Opus 4.x models , where token usage jumped about 30 percent from the tokenizer change alone. Real-world savings are likely smaller than the per-token prices suggest. Ad Haiku 5.5 scores 1,620 on the knowledge benchmark GDPval-AA v2.1, more than double the 735 its predecessor managed. On Humanity's Last Exam, it hits 45.9 percent without tools and 57.4 percent with tools, up from 10.2 and 18.7 percent. Ad The biggest jump is in computer use , where the model operates a computer on its own. Since computer use burns through large amounts of tokens, a cheap, fast model like Haiku 5.5 is a natural fit. It scores 72.4 percent on OSWorld-2.1, up from 15.7 percent. On the agentic coding benchmark Terminal-Bench 4.0, it reaches 39.2 percent while Haiku 4.5 scored zero. Anthropic also lists OpenAI's budget model GPT-6 Luna as a comparison, and Haiku 5.5 leads across every tested category. Sonnet 5.5 reference scores show, however, that Haiku 5.5 still falls well behind Anthropic's larger model. Ad Haiku 5.5 is the first Haiku-class model with adjustable reasoning levels, letting users balance cost against quality. Anthropic says the model works best for narrowly scoped tasks like compaction, summarization, or sub-agent work. For complex agentic coding, Sonnet 5.5 and Opus 5.5 remain the better picks. Cybersecurity safeguards are tighter than on the predecessor but allow a broader range of defensive tasks than Sonnet 5.5, partly because the model is less capable overall. Penetration testing stays blocked. Organizations with broader needs can apply for Anthropic's verification programs for life sciences and cybersecurity . Ad Haiku 5.5 is available now across all platforms, including Amazon Web Services, Google Cloud, and Microsoft Azure. Ad
