Anthropic has released its latest AI model with Claude Haiku 5.5. The new version arrives about a year after the previous Haiku model upgrade.<\/p>\n

Anthropic Claude Haiku 5.5<\/h2>\n

Anthropic currently offers a few Claude AI models.\u00a0<\/p>\n

The three main models are Haiku (smallest and cheapest), Sonnet (medium size and price), and Opus (largest and most expensive of the three).<\/p>\n

There\u2019s also Fable\/Mythos<\/a>, which is even more capable and costly, which represents Anthropic\u2019s highest tier.<\/p>\n

Today\u2019s release upgrades Claude\u2019s Haiku model from version 4.5 to version 5.5.<\/p>\n

This marks the third Claude 5.5 model upgrade over the last month, following Opus<\/a> and Sonnet<\/a> upgrades.<\/p>\n

Introducing Claude Haiku 5.5: the cheapest, fastest, and most capable small model we\u2019ve ever released.<\/p>\n

Claude Haiku 5.5 costs around 75% less to run<\/h2>\n

\u201cClaude Haiku 5.5 is designed for high-volume, cost-sensitive tasks,\u201d Anthropic says. \u201cIt reliably handles quick and repetitive workloads (like summaries, compactions, database queries, and classification requests). It pairs well with Opus 5.5 and Sonnet 5.5 as a subagent on coding work. And, since it\u2019s also our fastest model to date, it works especially well for speed-sensitive tasks like live customer support and browser use.\u201d<\/p>\n

Anthropic adds that Haiku 5.5 \u201ccosts around 75% less to run\u201d than the previous model version that it replaces.<\/p>\n

\u201cAlong with this launch, we\u2019re making improvements to the value of our model range,\u201d says Anthropic. \u201cWe\u2019re halving the price of Claude Sonnet 5.5\u2019s cache reads, which means Sonnet 5.5 now runs around 20% cheaper on most agentic work. And we\u2019re introducing a new monthly API credit for our Claude Max and Team subscribers, designed to support our users in building new agents and applications that run on the Claude Platform.\u201d<\/p>\n

On its website, Anthropic compares Claude Haiku 5.5 to OpenAI\u2019s GPT-5.5 Luna, another low-cost model. You can see all of the details about Anthropic\u2019s newest low-cost model here<\/a>.<\/p>\n
