Anthropic releases OPUS 4.5 with New Chrome and Excel

On Monday, anthropic announced OPUS 4.5, the latest version of its unusual version. It is the last of Anthropic’s 4.5 versions to be released, following the launch of Sonnet 4.5 in September and Hauku 4.5 in October.

As expected, the new version of the opus has different functions, including the bench and the terncy (tambalal-beamondi 2, GPQA Daimond).

Appropriately, OPUS 4.5 is the first version to record 80% on a certified bench, a respectable feature.

Anyezipic also emphasized the use of opos computers and proplesheets, and set up a number of benchmarks for the brand. Together with opos 4.5, anthropic will create Claude of Chrome and Claude Preyl The product – previously the pilot – is available. The chrome extension will be available to all Max users, while the premium version is available to Max, team, and business users.

OPUS 4.5 also comes with long-term Memory changes, which require significant changes in how the model remembers.

“There is a long-term improvement in education with OPUS 4.5, but widi Windows is not enough,” Anthripic topic is not enough. “Knowing the details of the memory is very important for the complete implementation of just having the Internet.”

This change also helped paid claude users, who would allow watts to continue without interruption if the model hits its window. Instead, the model will embrace memories that are unknown to the user.

Most of the upgrades are made with an eye to use cases, especially the situations where the apos act as a director leads a group of haku agents. Managing those jobs requires a strong work ethic, where the systematic approach described by Penn shows their importance.

Penn said: “This is where memory as memory becomes really important.”

OPUS 4.5 will face stiff competition from other recent releases, especially GPT 5 (Released on November 12) and Gemini 3 (Released on November 18).
