SWE-bench Complex

A contamination-free, complexity-focused evaluation set for AI coding agents.

SWE-bench Complex is a curated dataset of 119 real-world GitHub issues from major Python open-source projects, designed specifically for studying code complexity in AI-generated patches. All tasks were merged between January–March 2026, guaranteeing they postdate the training cutoff of current frontier models.

Why SWE-bench Complex?

Existing benchmarks like SWE-bench Verified suffer from two problems for complexity research:

1. Data Contamination

Over 94% of SWE-bench issues predate current LLM training cutoffs. Aleithan et al. found that 32.67% of successful patches involve "cheating" through solution leakage, and resolution rates dropped from 12.47% to 3.97% when leaked instances were filtered out (SWE-bench+, 2024).

All SWE-bench Complex instances postdate the training cutoffs of:

Model	Provider	Training Cutoff	Gap
Claude Opus 4.6	Anthropic	Oct 2025	3+ months
GPT-5.3-Codex	OpenAI	Sep 2025	4+ months
GPT-5.4	OpenAI	Nov 2025	2+ months
Gemini 3.1 Pro	Google	Oct 2025	3+ months

2. Trivial Patches

SWE-bench Verified has a median patch size of just 7 changed lines — 44.6% of tasks require only 1–5 lines. These trivial patches yield near-zero complexity deltas, reducing statistical power for quality studies.

SWE-bench Complex targets substantive patches with a median of 48 changed lines — 6.9× larger than SWE-bench Verified.

Dataset Comparison

Characteristic	SWE-bench Verified	SWE-bench Complex
Tasks	500	119
Repositories	12	8
Median changed lines	7	48
Mean changed lines	14.3	74.9
Mean Python files changed	1.2	3.9
Human ΔCC (mean)	+1.14	+4.06
Human ΔLLOC (mean)	+2.77	+19.08
Human ΔMI (mean)	−0.230	−0.417
Human ΔCogC (mean)	N/A	+3.63
Post-training-cutoff	<6%	100%

Complexity metrics measured using Wily v2:

ΔCC: Cyclomatic Complexity change (McCabe, 1976)
ΔLLOC: Logical Lines of Code change
ΔMI: Maintainability Index change (Oman & Hagemeister, 1992)
ΔCogC: Cognitive Complexity change (Campbell, 2018)

Repository Distribution

Repository	Instances

Selection Criteria

Instances were collected from merged pull requests in the SWE-bench ecosystem repositories with the following filters:

Date range: Merged January 1 – March 10, 2026 (post-training-cutoff)
Issue linkage: PR explicitly references a GitHub issue via "fixes #N" or equivalent
Test coverage: PR includes both implementation and test changes to Python files
Minimum complexity: Implementation patch modifies ≥4 changed lines
Python files: Only .py file changes retained
Manual review: Each candidate reviewed for solvability — documentation-only changes, large-scale refactors (>300 lines or >10 files), and tasks requiring external domain knowledge were excluded

From 1,043 scraped PRs → 712 with issue references → 224 after automated filters → 119 after manual review.

Schema

Each instance contains:

Field	Type	Description
`instance_id`	string	Unique identifier (`{owner}__{repo}-{pr_number}`)
`repo`	string	GitHub repository (`owner/repo`)
`base_commit`	string	Parent commit SHA
`problem_statement`	string	GitHub issue text (title + body)
`test_patch`	string	Unified diff of test-file changes
`human_patch`	string	Unified diff of implementation-file changes
`pr_number`	int	Pull request number
`pr_url`	string	Pull request URL
`pr_merged_at`	string	Merge timestamp (ISO 8601)
`issue_number`	int	Referenced issue number
`issue_url`	string	Issue URL
`human_changed_lines`	int	Total changed lines in the human patch
`FAIL_TO_PASS`	string	JSON array of test IDs that must go FAIL→PASS
`PASS_TO_PASS`	string	JSON array of test IDs that must remain PASS

SWE-bench Compatibility

SWE-bench Complex uses the same schema as SWE-bench Verified and can be evaluated using the standard SWE-bench harness:

python -m swebench.harness.run_evaluation \
    -d anthonypjshaw/SWE-bench_Complex \
    -s test \
    -p predictions.jsonl \
    -id my_run \
    --max_workers 4

Usage

from datasets import load_dataset

dataset = load_dataset("anthonypjshaw/SWE-bench_Complex", split="test")
print(f"Tasks: {len(dataset)}")
print(f"Repos: {len(set(dataset['repo']))}")
