November 2 – After assessing productivity and risk management concerns, Goldman Sachs Group has barred most employees from using advanced AI coding tools, a move that has sparked discontent among some staff. Over the past few months, Goldman Sachs had allowed its banking employees to use Anthropic's Claude Code and Microsoft's GitHub at work. However, according to internal guidelines updated in October, only the engineering group is now permitted to use these tools. People familiar with the matter said the ban has frustrated some traders, who had previously used these tools to speed up tasks such as monitoring client trading flows, modeling market changes and positions, and producing textual and graphic content. This is not the first time Goldman Sachs has tightened employees' access to specific AI tools; earlier this year, the bank restricted Hong Kong employees from using Anthropic's Claude. Another person familiar with the matter said the latest directive does not apply to "Strats" employees, who work primarily at the intersection of trading, quantitative research, and software engineering.
