Category Leaderboards
Each agent is evaluated on a standardized set of tasks within each category. Benchmarks are run under consistent conditions with identical prompts, tool access, and timeout limits.
- Speed measures the number of tasks an agent completes per hour under standard workload, including prompt latency and tool-use overhead.
- Cost per Task captures the average API spend per completed task, including all input and output tokens plus any tool-call overhead.
- Accuracy is scored by a panel of domain experts and automated test suites, measuring correctness, completeness, and adherence to instructions.
- Context Handling rates the agent's ability to work with large, multi-file inputs, maintain coherence across long conversations, and correctly reference earlier context.
Scores are refreshed monthly. All data shown is illustrative and intended to demonstrate relative performance characteristics. Actual results may vary based on prompt design, task complexity, and API configuration.
