Anthropic launches new version of scaled-down “Haiku” model

On Wednesday, ethnographic Claud Haiku 5.1 published a new version of its smallest model, a similar performance in Sonnet 1 was given a similar performance “cost more than one third and more than doubled,” in the company’s blog post. While

Anthropic sites are the results of various new benchmarks to back up the claim of that performance. The company’s examination has been verified by Hiku SW-Bench 735% and 41% Sonnet 4.5 on the command-centric terminal-bench, but in each case the sonnet 4, GPT-5 and the generation 2.5 are equivalent. Tests show similar results in criteria for using equipment, use of computer and visual logic.

The new version of Haiku will be default for all free anthropological plans and the agency believes that it will apply specially for the free version of AI products, where it can provide significant ability to reduce the server loads. The lightweight nature of the model means that it is easy to place multiple haiku agents in parallel or in a combination of more sophisticated models.

In a statement for the press, ethnic CPO Mike Criger said that for the first time, Haiku would make the new style of deployment in production. “It is opening the entire new sections of what is possible with AI in the manufacturing environment-Sonnet implements the hiku-powered sub-agents in speed with the managing complicated plan,” said Criger. “We are giving people a full agent toolbox where each model has the exact combination of intelligence, speed and expenditure for different parts of the work.”

Most instant applications can come to software development tools, where the clad code is already commonly used and delay is often an important issue. In the ethnic given statement, Jencoder’s CEO Andrew Filev describes the new version of Hikur as “a whole new set unlocking”.

Hiku 4.5 comes after launching the high-profile for anthropological: just two weeks later The introduction of Sonnet 4.5 And after two months The introduction of OPAS 4.1Both were praised as sophisticated at the time of release. Hikur’s previous version Was released in October 2024.
