# Goldman Sachs: Proprietary AI Source: https://www.bankingnewsai.com/banks/goldman-sachs/proprietary-ai Last updated: Oct 22, 2026 *Part of the [Goldman Sachs AI strategy profile](https://www.bankingnewsai.com/banks/goldman-sachs).* ## What proprietary AI has Goldman Sachs built in-house? Goldman Sachs has built its own AI platform and assistants but not its own foundation model. CIO Marco Argenti said in October 2023 that the firm had no plans to build a large language model from scratch and would instead fine-tune existing models and use retrieval-augmented generation on its own data. What it built is the layer around those models: the GS AI Platform, a centralized internal platform with technical, legal and compliance checks, content filtering, logging of every interaction and a single chat interface the firm developed, which in June 2024 fronted Microsoft-hosted GPT-3.5 and GPT-4, Google Gemini and Meta Llama. On it runs the GS AI Assistant ('we built and we're deploying at scale our GS AI assistant', Argenti said in March 2025), which reached about 10,000 staff in January 2025 and all 46,000 employees by July 2025, with more than a million prompts a month. Argenti keeps the models 'plug-and-play' so the firm can pick a vendor by task. Other in-house systems: Marquee AI, which attributes each statement to a line in a source (internal only as of August 2026), the AlphaAI investing platform (July 2026), and Legend, a data platform built internally over 10 years before it was open-sourced in 2020. Agents are bought or co-built: Cognition's Devin from July 2025 and Claude agents built with embedded Anthropic engineers (February 2026). The work sits under Daniel Marcu, Global Head of AI Engineering and Science, with named heads of GS AI platform engineering and of AI Research.

Argenti set the line in October 2023: 'I might be completely wrong, but I don't believe at this point... that it is necessary to start from scratch.' Instead the firm fine-tunes existing models and uses retrieval-augmented generation, because 'a lot of stuff out there is generic, but there is data that we have, that is the most important thing.' Fortune reported the same position in June 2024: integrate GPT-3.5, GPT-4, Gemini and Llama into Goldman's own platform rather than build a model. ([VentureBeat](https://venturebeat.com/ai/goldman-sachs-cio-is-anxious-to-see-results-from-genai-but-moving-carefully-the-ai-beat/), [Fortune](https://fortune.com/2024/06/28/goldman-sachs-cio-ai-superhuman-productivity-superhumanly-smart/)) The platform is multi-vendor by design. Argenti told Fortune in March 2025 that he does not want to rely on one vendor, that one model may be better for coding and another for reasoning, and that the firm weighs how easy each model is to modify and how expensive it is to run: 'All of those considerations got us to the point where we want to continue to plug-and-play with those models.' ([Fortune](https://fortune.com/2025/03/19/goldman-sachs-cio-ai/)) Chris Churchman, who leads Marquee AI, put the build rule as 'don't bet against the model': build what a model cannot learn, such as the firm's entitlements, mandates and the way its data sets connect, because reasoning scaffolds and retrieval pipelines built around older models' limits were made 'totally pointless' by reasoning models, longer context windows, function calling and MCP. ([Goldman Sachs](https://goldmansachs.com/insights/goldman-sachs-exchanges/building-ai-systems-for-capital-markets)) For agents Goldman buys and co-develops rather than builds alone: Devin comes from Cognition, in which it holds no stake, and the accounting and onboarding agents were built on Claude with Anthropic engineers working inside the bank. ([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)) ## What has Goldman Sachs not disclosed about its proprietary AI? No model trained by Goldman from scratch is on the record, and the firm's stated position since 2023 is that it does not need one. It has not said which fine-tuned models run in production or what share of the GS AI Assistant's million-plus monthly prompts goes to each vendor. ([VentureBeat](https://venturebeat.com/ai/goldman-sachs-cio-is-anxious-to-see-results-from-genai-but-moving-carefully-the-ai-beat/), [American Banker](https://www.americanbanker.com/news/goldman-sachs-staff-now-write-a-million-gen-ai-prompts-a-month)) Headcount for GS AI platform engineering and AI Research is not published; the January 2025 memo names their heads only. No AI platform budget is disclosed. Goldman holds AI patents granted in 2026 on embedding-model fine-tuning and embedding-free retrieval-augmented generation, but has not said which in-house system uses them.

Not from scratch. CIO Marco Argenti said in October 2023 that he did not believe it was necessary to start from scratch; the firm fine-tunes existing models and uses retrieval-augmented generation on its own data. What Goldman builds is the GS AI Platform, the GS AI Assistant, Marquee AI, AlphaAI and the Legend data platform, all running on or around third-party models from OpenAI, Google, Meta and Anthropic. ### What is the GS AI Assistant built on? It runs on the firm's GS AI Platform. In January 2025 it drew on OpenAI, Google Gemini and Meta Llama models fed with Goldman data, with Anthropic, Mistral and Cohere under evaluation; by July 2025 staff could choose among current GPT, Gemini and Claude models. Argenti says the firm wants to keep plugging models in and out by task and cost. ### Who builds AI at Goldman Sachs? CIO Marco Argenti oversees it. Daniel Marcu, hired from Amazon, is Global Head of AI Engineering and Science; Rahul Sharma heads GS AI platform engineering and Bing Xiang heads AI Research within Engineering, both reporting to Marcu. Archana Vemulapalli runs AI product management and frontier-lab relations, and Chris Churchman leads Marquee AI. ### What is Marquee AI? Marquee AI is a natural-language assistant on Marquee, Goldman's digital platform for institutional and corporate clients. It breaks a question into research topics and attributes every statement to a specific line in a source, using a grounding framework the team built. As of August 2026 it was available internally only. ### How many Goldman Sachs employees use its in-house AI? The GS AI Assistant reached about 10,000 employees in January 2025 and all 46,000 by July 2025, handling more than a million prompts a month. GitHub Copilot on the GS AI platform launched to more than 9,000 developers, about 80% of engineers, in June 2024. ## 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) - [What technology stack does Goldman Sachs use for AI?](https://www.bankingnewsai.com/banks/goldman-sachs/technology-stack) - [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/proprietary-ai Part of [BankingNewsAI](https://www.bankingnewsai.com/) — a free daily brief on AI in banking, an AI regulation tracker (43 authorities, 244 documents) and AI-strategy profiles of the 120 largest US banks.
