A senior global quant investor from Goldman Sachs’ asset management arm has downplayed concerns over risks from the rise of DeepSeek, offering insight into how the firm integrates artificial intelligence into its investment process.

Speaking at the Portfolio Construction Forum Market Summit 2025 on Wednesday, Dennis Walsh, global co-head of quantitative investment strategies at Goldman Sachs, said large language models (LLMs) play a significant role in the investment team's decision-making.

When asked whether GSAM used DeepSeek or viewed it as a threat to Western dominance in AI, Walsh said his team welcomed major breakthroughs in open-source models.

"We have always been big proponents of open-source models. We still are. We like the fact that we can actually have full control of that model end to end, which is quite important," Walsh said.
