ScienceAgentBench
ScienceAgentBench is a benchmark for rigourously evaluating the ability of language agents to conduct data-driven scientific discovery.
Key Features of ScienceAgentBench
Real-World Scientific Tasks
All tasks are sourced from 44 peer-reviewed publications.
Expert Validation
Each of the 102 tasks was validated by nine subject matter experts (senior PhD students and professors) to ensure quality.
Rigourous and Fair Evaluation
Evaluation metrics are diverse and effective strategies are employed to mitigate data contamination, ensure annotation quality and scientific plausibility.
ScienceAgentBench Leaderboard
Costs are currently calculated without accounting for caching benefits.

Accuracy vs. Cost Frontier for ScienceAgentBench
This plot shows the relationship between an agent's performance and its token cost. The Pareto frontier (dashed line) represents the current state-of-the-art trade-off. The error bars indicate min-max values across runs.
Total Completion Tokens Used per Agent
The bar chart shows the total completion tokens used by each agent, with the height of each bar representing the total number of completion tokens used across all tasks. Secondary models usually contribute a relatively small amount of tokens in comparison, and are used for RAG or image processing only.
Model Performance Over Time
Track how model accuracy has evolved over time since their release dates. Each point represents the best performance achieved by that model on ScienceAgentBench.
Token Pricing Configuration
Adjust token prices to see how they affect the total cost calculations in the leaderboard and plots.
