# Goldman Sachs: Technology stack Source: https://www.bankingnewsai.com/banks/goldman-sachs/technology-stack Last updated: Oct 16, 2026 *Part of the [Goldman Sachs AI strategy profile](https://www.bankingnewsai.com/banks/goldman-sachs).* ## What technology stack does Goldman Sachs use for AI? Goldman Sachs runs AI through the GS AI Platform, a firm-hosted single entry point described in June 2024 as fronting Microsoft-hosted GPT-3.5 and GPT-4, Google Gemini and Meta Llama; by July 2025 staff could pick among current GPT, Gemini and Claude models, with prompt controls that flag the information users enter. The GS AI Assistant on that platform reached all 46,000 employees in July 2025. Engineering is the deepest layer: GitHub Copilot for 12,000 developers since 2024, Cognition's Devin from July 2025, and by August 2026 hundreds of agents working beside 12,000 engineers on production tasks, starting with legacy modernization; CIO Marco Argenti reported up to 20% efficiency gains. Data runs on Legend, the data-modeling platform Goldman open-sourced through FINOS in 2020, and Legend lets staff search firm files in natural language. In the cloud, Goldman built Financial Cloud for Data with AWS in 2021, and CFO Denis Coleman said in April 2026 that OneGS 3.0 is bringing forward cloud migration and data-quality work because both are critical to deploying AI. Argenti, a former AWS executive, has described how agentic platforms such as Claude Code changed AI coding inside the bank (March 2026).

Both. Goldman builds the platform layer itself, the GS AI Platform and Assistant, and routes to models bought from several labs. Argenti, who previously worked at Amazon Web Services, discussed the development of Goldman's own internal AI tools on Bloomberg's Odd Lots in August 2024. ([The Wall Street Journal](https://wsj.com/articles/goldman-sachs-deploys-its-first-generative-ai-tool-across-the-firm-cd94369b), [Bloomberg](https://bloomberg.com/news/articles/2024-08-08/goldman-sachs-cio-on-how-the-bank-is-actually-using-ai)) For agents it buys and co-develops: Devin from Cognition, in which Goldman holds no stake, and Claude agents built with embedded Anthropic engineers. Argenti measures idea-to-production speed rather than individual AI usage: 'There's zero time between idea and prototype.' ([CNBC](https://www.cnbc.com/2025/07/11/goldman-sachs-autonomous-coder-pilot-marks-major-ai-milestone.html), [CNBC](https://www.cnbc.com/2026/02/06/anthropic-goldman-sachs-ai-model-accounting.html), [Fortune](https://fortune.com/2026/05/08/goldman-sachs-cio-marco-argenti-tech-ai-future-of-work-employees/)) Not disclosed: Goldman's split between cloud and its own data centers, its GPU capacity or a technology budget figure. Its patents point to in-house work on retrieval-augmented generation, embedding models and coding-assistant context.

It is Goldman Sachs' firm-hosted gateway to generative AI. Reported in June 2024 as the single entry point for generative AI, it put Microsoft-hosted GPT-3.5 and GPT-4, Google Gemini and Meta Llama behind one interface; by July 2025 staff could choose among current GPT, Gemini and Claude models. The GS AI Assistant runs on it. ### What coding tools do Goldman Sachs engineers use? Its 12,000 developers have had GitHub Copilot since 2024. Cognition's autonomous engineer Devin joined teams in July 2025 and Forbes reported in August 2026 that hundreds of agents work beside the engineers on production tasks. CIO Marco Argenti cited up to 20% efficiency gains from the Devin pilots. ### Which cloud does Goldman Sachs use? Goldman built Goldman Sachs Financial Cloud for Data with AWS, announced at re:Invent in November 2021, for institutional clients' data and analytics. CFO Denis Coleman said in April 2026 that OneGS 3.0 is accelerating cloud migration and data-quality work because both are critical to deploying AI. The full cloud footprint is not disclosed. ### What is Goldman Sachs Legend? Legend is Goldman's data-modeling and governance platform, open-sourced through FINOS in October 2020. Inside the bank it lets staff search firm files in natural language without knowing where a document sits, according to CIO Marco Argenti in May 2026. ## Deeper on Goldman - [What is Goldman Sachs' AI strategy?](https://www.bankingnewsai.com/banks/goldman-sachs/ai-strategy) - [What AI research, patents and partnerships does Goldman Sachs have?](https://www.bankingnewsai.com/banks/goldman-sachs/ai-research-patents-partnerships) - [How does Goldman Sachs govern AI and manage its risks?](https://www.bankingnewsai.com/banks/goldman-sachs/responsible-ai) --- Canonical page: https://www.bankingnewsai.com/banks/goldman-sachs/technology-stack Part of [BankingNewsAI](https://www.bankingnewsai.com/) — a free daily brief on AI in banking, an AI regulation tracker (42 authorities, 243 documents) and AI-strategy profiles of the 120 largest US banks.
