Goldman Sachs has cut most of its employees off from advanced AI coding tools, including Anthropic's Claude Code and Microsoft's GitHub. From now on only software engineers will be able to use them. The decision comes from internal guidelines updated in October, according to Bloomberg, and it has reportedly frustrated staff.

For months, traders and bankers had used these tools for tasks far removed from programming: monitoring client trading flows, building models of market moves and positions, and producing written and graphic content. The change hits exactly those uses, and Bloomberg reports that some traders are unhappy about it.

The reversal is striking given the tone the bank struck only recently. In July, chief information officer Marco Argenti praised "vibe coding", the practice in which non-technical staff build quick prototypes with AI and hand them to an engineer to bring into production. According to Bloomberg, that model is no longer the plan.

The stated reasons

Spokesperson Nick Carcaterra attributes the decision to "a variety of factors including productivity and risk management". He added that the experimentation phase is over and that the tools will stay with those best placed to use them over the long term. No incident, cost or internal audit behind the decision has been made public.

The episode shows how delicate it is to let non-technical staff use coding agents: once an organisation decides who keeps access after a pilot, the question of who owns and maintains what was built becomes central.
