CEO-Bench: Can AI Agents Play the Long Game?

๐กDiscover why even top-tier models like GPT-5.5 struggle with long-term strategic planning in simulated business tasks.
โก 30-Second TL;DR
What Changed
Evaluates agents on long-horizon tasks like pricing, marketing, and budgeting.
Why It Matters
This benchmark highlights the current limitations of LLMs in multi-step, long-term reasoning. It provides a new standard for measuring agentic progress beyond isolated, short-horizon tasks.
What To Do Next
Review the CEO-Bench GitHub repository to test your agent's performance on long-horizon business logic tasks.

๐ Enhanced Key Takeaways
- โขCEO-Bench aims to measure "steering intelligence," which encompasses navigating long horizons, acquiring information in noisy environments, adapting to a changing world, and orchestrating multiple moving parts towards a coherent goal.
- โขThe simulation environment is designed to be partially observable, featuring hidden information such as true customer satisfaction and competitor schedules, and provides indirect feedback, making it challenging for agents to identify isolated causal relationships.
- โขBeyond just profitability, CEO-Bench evaluates models across four key executive competencies: Strategic Thinking, Operational Excellence, Leadership & Communication, and Financial Acumen.
- โขA multi-agent variant of CEO-Bench exists where LLM agents act as a CEO, integrating potentially conflicting advice from four role-conditioned C-suite advisors (CFO, CTO, COO, CMO) to formulate resource allocation plans.
- โขThe top-performing models on CEO-Bench, such as Claude Opus 4.8 and GPT-5.5, exhibit advanced strategic behaviors including simulating customer cohorts for financial forecasting, mining negotiation history for customer preferences, and crafting more conditional plans.
๐ Competitor Analysisโธ Show
CEO-Bench is part of a growing landscape of AI agent benchmarks focused on long-horizon planning and complex decision-making. A notable competitor with a similar focus on startup simulation is YC-Bench.
| Feature / Benchmark | CEO-Bench | YC-Bench |
|---|---|---|
| Simulation Duration | 500 days (simulated AI startup) | 1 year (hundreds of turns, simulated tech startup) |
| Primary Focus | Long-horizon planning, noisy data analysis, adaptive decision-making in general business (pricing, marketing, budgeting) | Long-term planning, consistent execution, employee management, task selection, client trust, adversarial client detection |
| Starting Capital | $1M | $200K |
| Interface | Programmable Python interface (novamind_api) | CLI against a SQLite-backed discrete-event simulation |
| Evaluation Metrics | Cash balance at simulation end; also Strategic Thinking, Operational Excellence, Leadership & Communication, Financial Acumen | Net worth, bankruptcy rate; also scratchpad usage, adversarial client detection |
| Top Performing Models (as of current data) | Claude Opus 4.8, GPT-5.5 (struggle to maintain profitability, but finish above starting balance on best runs) | Claude Fable 5, Claude Opus 4.7, Claude Opus 4.8 (consistently surpass starting capital) |
Other relevant benchmarks include AgentBench and WebArena for multi-turn open-ended tasks and web interactions respectively, TheAgentCompany for enterprise workflows, ALE-Bench for algorithmic programming contests, and HeroBench for planning in virtual RPG worlds.
๐ ๏ธ Technical Deep Dive
- Agents interact with the CEO-Bench simulator through a programmable Python interface, utilizing a package named
novamind_api. - The interface offers granular action spaces covering various business functions, including pricing, marketing, R&D, operations, enterprise sales, information acquisition, and public communication.
- The primary performance metric is the cash balance at the end of the 500-day simulation, with agents starting with $1 million.
- The simulated environment features partially observable, noisy, and evolving market dynamics, characterized by delayed and coupled consequences, making it difficult to isolate single causal relationships.
- Agents receive information through various channels such as dashboards, database records, social media posts, research reports, and negotiation histories, mirroring real-world data availability.
- In its multi-agent configuration, a CEO agent is tasked with synthesizing and integrating conflicting recommendations from four C-suite executive advisors (CFO, CTO, COO, and CMO), each possessing private signals and distinct priorities.
- The evaluation framework for the multi-agent setup measures specific dimensions including role integration, strategic boldness calibration, history sensitivity, and plan validity.
- The overall evaluation process is Python-based, employing custom scripts and the
llmcommand-line interface for tasks like question generation, answer grading, and result aggregation.
