Brackett has released the Agent Effectiveness Index, an open-source framework designed to measure how well AI agents execute complex business processes. The benchmark evaluates systems based on their ability to handle operational tasks, manage exceptions, and retain learned behaviors.
Why it matters
Current evaluation models often rely on static knowledge tests, which fail to capture how AI agents perform in real-world business roles. This new index provides a standardized way for organizations to measure an agent's reliability in operational execution.
The framework utilizes a set of tasks and scoring methodologies to measure three core areas: business understanding, operational execution, and learning persistence. The benchmark is currently licensed under an MIT license for public use.
The players
Brackett
A San Francisco-based company founded by former technical leaders from Microsoft, Rubrik, and Amazon.
OpenAI
An artificial intelligence research organization whose Codex system was included in the new index.
Anthropic
An AI safety and research company that had its Claude system evaluated by the new framework.
Focal
A venture capital firm that provides financial backing to Brackett.
Heavybit
A specialized venture capital firm that invests in companies like Brackett.
The details
The platform tests whether agents can ground their answers in evidence and produce consistent outcomes while navigating complex exception handling. By focusing on behavioral retention, the framework aims to ensure that AI systems can effectively serve in operational roles.
Timeline
September 28, 2026: Brackett launched the Agent Effectiveness Index.
The Tech Race
The release of this open-source benchmark aligns with the industry movement to prioritize functional process reliability over static language model capabilities. By using the MIT license, the framework seeks to establish itself as a standard for evaluating autonomous business agents.
Business users and developers can now access this framework to objectively compare how different AI agents perform under real-world operational pressure. This provides a clearer standard for deciding which AI systems are ready for professional deployment.
The takeaway
Reliability in business settings requires agents that can handle exceptions rather than just answering questions correctly. Organizations should focus on these new process-oriented benchmarks to determine if their AI tools are truly ready for integration into daily operations.
