Antarbur launched the New Claude 4 Gen Ai models. This is what they are doing

The latest versions of the anthropor Claude Temporary artificial intelligence models It appeared for the first time on Thursday, including a heavier model in service designed specifically for coding and complex tasks.

I launched the new anthropologist Claude 4 Obus and Claude 4 Sonit Models during its blog with the Claude Conference of the developer, and executive managers said that the new tools determine an important step forward in terms of thinking and deep thinking skills.

The company launched the previous model, Claude 3.7 Sonnet, in February. Since then, artificial intelligence developers have increased their game. Openai GPT-4.1 was released in AprilFocusing on an expanded context window, along with the new O3 Thinking Form family. Google followed in early May with An updated version of Gemini 2.5 Pro He said he was better in coding.

CLAUDE 4 OPUS is a larger and more intense resource model designed to deal with special challenges in particular. Anthropor CEO, Dario Amani, said that test users have seen that he was dealing quickly with the tasks that may have taken several hours to complete.

He said during “in many ways, as we often find with large models Major.

Claude 4 Sonnet is a smaller model, with improvements based on the Claude 3.7 Sonnet model. Amani said the 3.7 model often had problems with excessive opinion and sometimes doing more than the person asked to do. He said that while it is a less dense resource model, it is still a good performance.

“In fact, it is also also on some coding criteria, but I think it is focused in a more narrow way,” said Amoudi.

Anthropor said the models have a new ability, still conducting a experimental test, as they can use tools such as web searches while participating in expanded thinking. Models can alternate between thinking and use tools to get better responses to complex queries.

Models offer all of the response conditions close to the fixed and extended thinking patterns.

All paid plans are offered OPUS and Sonnet, while the free plan has only Sonnet model.
