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.
Anthropic currently offers a few Claude AI models.
The three main models are Haiku (smallest and cheapest), Sonnet (medium size and price), and Opus (largest and most expensive of the three).
There’s also Fable/Mythos, which is even more capable and costly, which represents Anthropic’s highest tier.
Today’s release upgrades Claude’s Haiku model from version 4.5 to version 5.5.
This marks the third Claude 5.5 model upgrade over the last month, following Opus and Sonnet upgrades.

“Claude Haiku 5.5 is designed for high-volume, cost-sensitive tasks,” Anthropic says. “It 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’s also our fastest model to date, it works especially well for speed-sensitive tasks like live customer support and browser use.”
Anthropic adds that Haiku 5.5 “costs around 75% less to run” than the previous model version that it replaces.
“Along with this launch, we’re making improvements to the value of our model range,” says Anthropic. “We’re halving the price of Claude Sonnet 5.5’s cache reads, which means Sonnet 5.5 now runs around 20% cheaper on most agentic work. And we’re 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.”
