ClawBench — A Benchmark for AI Web Agents

Can AI Agents Complete Everyday Online Tasks?

|💻 Github | 🏆 Leaderboard | 📖 Paper | 🌐 Website |

ClawBench is an open benchmark for AI web agents — the systems that drive a real browser to complete a user's task end-to-end. It scores agents on real, everyday online tasks (booking flights, ordering groceries, submitting job applications) across live websites. The corpus ships in two slices: V1 — 153 tasks across 144 websites (the original frontier-model leaderboard) and V2 — 130 newer tasks (expanded coverage). For each run we capture 5 layers of behavioral data (session replay, screenshots, HTTP traffic, agent reasoning traces, and browser actions), collect human ground-truth, and score with an agentic evaluator that provides step-level traceable diagnostics.

Install: pip install clawbench-eval (PyPI) · Companion raw traces: NAIL-Group/ClawBenchV1Trace

🚀 What's New

• [2026.05.12] Added the V2 corpus (130 newer tasks across 63 platforms) and 7 new models judged with deepseek/deepseek-v4-pro — see snapshot below. Companion V2 traces released at NAIL-Group/ClawBenchV2Trace.
• [2026.05.04] Reorganized to the clawbench-eval package. Single command for both V1 and V2: clawbench run --corpus v2 --model <m> --harness hermes.
• [2026.04.18] Published NAIL-Group/ClawBenchV1Trace — full 5-layer execution traces (recording, actions, HTTP, agent messages, interception) for every V1 run.
• [2026.04.06] Paper preprint up: arXiv:2604.08523 — Can AI Agents Complete Everyday Online Tasks?

🏆 Leaderboard

Live results — pulled from leaderboard/results.csv in this repo. Sort by corpus (v1 / v2 / all) and submit your model in the interactive Space:

V2 snapshot — refreshed 2026-05-12 (full scoring logic: eval/scoring.md)

Intercepted (sort key) = fraction whose final HTTP request matched the per-task URL/method schema — Stage 1, deterministic, no judge. Reward = additionally requires an LLM judge (default deepseek/deepseek-v4-pro) — Stage 2. Rows ranked by Intercepted DESC, Reward as tiebreak. V2 is Hermes-only; alternative harnesses are evaluated separately. Partial = batch attempted < 130 V2 tasks; rates are over attempted, not over 130.. Companion traces in NAIL-Group/ClawBenchV2Trace. See scoring.md, live leaderboard Space.

Submit a result → run clawbench-eval on your model and open a PR to leaderboard/results.csv — one row per (model × harness × corpus).

Companion datasets (raw traces): NAIL-Group/ClawBenchV1Trace (V1 runs) · NAIL-Group/ClawBenchV2Trace (V2 runs, rolling) — recording.mp4, requests.jsonl, actions.jsonl, agent-messages.jsonl, interception.json, run-meta.json per model run.

Additional Files

shared/
  alex_green_personal_info.json   # Shared dummy user profile used across all tasks
extra_info/
  004/grocery_list.json           # Task-specific context (32 tasks have extra info)

• shared/alex_green_personal_info.json — A comprehensive dummy user persona (Alex Green) including personal details, address, work history, education, financial information, and preferences. All tasks share this identity.
• extra_info/ — Task-specific supplementary files referenced by the extra_info column. 32 of 153 tasks include additional context such as grocery lists, job links, meeting details, etc.

eval_schema

The eval_schema field configures the request interceptor — a mechanism that blocks the final HTTP request matching the specified URL pattern and method, preventing irreversible actions (checkout, form submission, etc.) from reaching the server. This allows safe evaluation on live websites.
