Explicit Edit Benchmark

226 deterministic exact-edit tasks, run by different agents, harnesses, models and configurations. Every observation records what the harness did and whether the resulting files matched byte for byte.

Source code and benchmark runner: GitHub — Explicit Edit Benchmark

Open the interactive Explorer to compare agents, harnesses, models, versions, reasoning modes, correctness, recovery, time, cost and tokens.

Leaderboard by model

Score v2 = coverage × quality, where quality is 75% first exact and 25% final exact. Repeated runs are averaged inside each configuration and task; configurations then have equal weight inside each task, and tasks have equal weight. The same numbers are in views.json, and the Explorer breaks them down by harness, version and reasoning mode.

Model Score Coverage Tasks Observations Harnesses
deepseek-v4.1-flash-expires-on-0910 97.7% 100.0% 226 1808 8
deepseek-v4-flash 97.3% 100.0% 226 1808 8
glm-5.3-flash 92.1% 100.0% 226 1808 8
gpt-5.6-luna 91.2% 100.0% 226 8604 34
mimo-v2.5 86.5% 100.0% 226 1808 8

The harness list behind each row is in data/models.jsonl.gz, and views.json holds the same aggregates for the other groupings: by harness, by agent and by reasoning mode.

Tables

Config One row per
profiles configuration that was run, with its agent, harness, model and exact versions
configurations recipe behind a configuration, safe to publish
trials task and attempt, with the first and final exact result
rounds attempt, with timing, tokens, cost and timeout state
tool-calls tool the agent used, with its category and outcome
submissions accepted run, with its owner, purpose and definitions

The Dataset Viewer shows every config. dataset-index.json holds the source hashes, contracts, task sets, completeness and counts, and views.json, leaderboard.json and summary.json hold the aggregated rankings.

Source and contribution

Source code, run instructions and the contribution guide live at alexshpunt/explicit-edit-benchmark. Accepted bundles are kept under source/, the shards and summaries are views rebuilt from them, and each accepted harness family has a README badge under badges/.

Observations hold no prompts, arguments, commands, output, sessions, workspaces or credentials.
