Nov 24 (Reuters) - Artificial intelligence startup

Anthropic unveiled an upgraded Opus model on Monday, boosting

Claude's ability to write detailed code, create sophisticated

agents and streamline enterprise workflows through spreadsheet

and financial analysis.

The new model comes as Amazon ( AMZN ) and Alphabet-backed

Anthropic races against OpenAI and other rivals to

develop cutting-edge large language models aimed at achieving

capabilities that could surpass human intelligence.

Opus 4.5 ranks among the most powerful models in the Claude

family, offering deep reasoning and memory, coding and a

versatile performance across a range of computer applications,

including financial tasks such as modeling and forecasting.

Its agents autonomously refine their own capabilities and

store insights from past work to apply at a later date,

Anthropic said.
