How Balyasny Asset Management built an AI research engine for investing

By combining rigorous model evaluation, full-platform use of OpenAI, and sophisticated agent workflows, Balyasny is reinventing investment research.

Balyasny Asset Management(opens in a new window) (Balyasny) is a global, multi-strategy investment firm with approximately 180 investment teams across diverse asset classes and geographies. The firm operates in a highly competitive and dynamic industry where conviction, precision, and speed are all critical to success. Facing an increasingly complex market environment with surging volumes of financial data, Balyasny saw an opportunity to reimagine the investment research process using AI.

In late 2022, Balyasny established an Applied AI team: a centralized group of 20 researchers, engineers, and domain experts tasked with building AI-native tools that embed directly into team-level workflows. Their flagship product, an AI investment research system, is designed to reason, retrieve, and act like a skilled analyst.

“AI is enabling our teams to apply first principles thinking faster, across more data, and with more structure.”

Investment research is complex, high-stakes, and time-sensitive. Analysts must parse through thousands of documents, from market data and research to regulatory filings. Human expertise remains essential, but traditional methods are time-consuming and difficult to scale.

Off-the-shelf AI tools often can’t handle structured and unstructured data together, lack workflow orchestration, and aren’t built to meet institutional compliance standards. Balyasny needed something purpose-built: an AI system that could think like an analyst, move at the speed of a machine, and work within strict compliance boundaries.

1. Evaluate models before deploying them

Before any models went into production, Balyasny built one of the most sophisticated evaluation pipelines in finance, measuring models across 12+ dimensions including forecasting accuracy, numerical reasoning, scenario analysis, and robustness to noisy inputs. These evaluations are run against Balyasny’s internal benchmarks, tools, and proprietary financial data.

This rigorous process surfaced strengths in the GPT‑5.4 model family, particularly in multi-step planning, tool execution, and hallucination reduction. Today, Balyasny uses GPT‑5.4 as a reasoning engine within their AI system, alongside internal models, which are selected task-by-task based on empirical performance.

“We evaluate models the way we evaluate investments: on fundamentals. GPT-5.4 proved it could plan, reason, and execute with real rigor.”

2. Foster deep collaboration between users and AI partners

Balyasny made a strategic decision to involve OpenAI directly in user-facing workflows. OpenAI teams observed directly how investment teams use their AI system: where it succeeds, where it struggles, and what high performance actually looks like in a commercial context.

That visibility led to faster iterations, tighter product feedback loops, and better model behavior in finance-specific tasks. As a design partner for frontier model releases, Balyasny has influenced the OpenAI roadmap by surfacing insights from actual analysts, not test cases.

“We didn’t just tell OpenAI what we needed. We showed them. And that made all the difference.”

3. Design for feedback loops, not static tools

Because AI is deeply embedded in the day-to-day workflows of investment teams, they can collect structured feedback in real time on everything from user evaluations and outcome audits to tool execution quality. That loop drives rapid improvements to both models and the orchestration layer.

For example, early feedback from merger arbitrage teams revealed that agents needed to continuously re-evaluate deal probabilities as new filings or press releases came in. The Balyasny team quickly extended agent planning capabilities and tool access, replacing a slow, manual workflow with real-time probabilistic monitoring.

4. Centralize your AI system, and customize locally

While each investment team has a distinct investment strategy, Balyasny took a centralized approach to AI deployment. Their Applied AI team develops core components, including agent frameworks, toolchains, and compliance guardrails, which are then deployed across teams with scoped access to data and tools.

This “federated deployment” model means each investment team can develop and use AI agents tailored to their asset class (for example, macro, commodities, and equities), while the Applied AI team focuses on scaling architecture, research, and model evaluations. It also ensures that compliance and regulatory standards are universally respected—critical in an industry where risk management and data security are non-negotiable.

“Our early investments in AI paid off. Today, every one of our investment teams can decide how to apply the latest AI to their process, in a secure environment and with real-time expert guidance.”

Today, **~95% of Balyasny investment teams actively use their AI platform, **with measurable impact across velocity, output quality, and analyst experience:

Deep research tasksthat once required days are now completed in hours, with agents synthesizing tens of thousands of documents, including filings, research, and earnings.- A Central Bank Speech Analystcut macroeconomic scenario analysis time from 2 days to ~30 minutes. - A Merger Arbitrage Superforecasteragent now monitors and updates deal probabilities continuously, replacing bespoke spreadsheets and manual alerts.

Just as importantly, analysts at Balyasny report higher confidence in outputs. With scoped tools, traceable reasoning paths, and testable agents, they use AI to deliver structured, explainable insights that increase conviction and inform human decision making.

Balyasny continues to expand its AI roadmap with a focus on:

Reinforcement Fine-Tuning (RFT)to sharpen model behavior on complex, high-value tasksDeeper agent orchestrationacross financial domainsMultimodal inputsincluding financial charts, statements, and filings- Evaluation of future frontier modelsfor domain fit

“It’s like adding a teammate who never forgets, always cites sources, and double-checks the details before sending anything back.”
