SWE-Universe: Scale Real-World Verifiable Environments to Millions
Published 2 Feb 2026 in cs.SE and cs.AI | (2602.02361v1)
Abstract: We propose SWE-Universe, a scalable and efficient framework for automatically constructing real-world software engineering (SWE) verifiable environments from GitHub pull requests (PRs). To overcome the prevalent challenges of automatic building, such as low production yield, weak verifiers, and prohibitive cost, our framework utilizes a building agent powered by an efficient custom-trained model. This agent employs iterative self-verification and in-loop hacking detection to ensure the reliable generation of high-fidelity, verifiable tasks. Using this method, we scale the number of real-world multilingual SWE environments to a million scale (807,693). We demonstrate the profound value of our environments through large-scale agentic mid-training and reinforcement learning. Finally, we applied this technique to Qwen3-Max-Thinking and achieved a score of 75.3% on SWE-Bench Verified. Our work provides both a critical resource and a robust methodology to advance the next generation of coding agents.
Summary
- The paper introduces a scalable framework that automates the construction of over 800,000 verifiable environments from real-world GitHub pull requests.
- It employs a custom-trained, efficient agent with iterative self-verification and in-loop hacking detection, leveraging a Mixture-of-Experts model for low latency and cost-efficiency.
- Empirical results demonstrate state-of-the-art non-hacked success rates of 78.44% and significant improvements in multilingual and agentic training benchmarks.
SWE-Universe: Scalable Construction of Real-World Verifiable Software Engineering Environments
Introduction and Motivation
SWE-Universe presents a systematic framework for automating the creation of verifiable, executable environments from real-world issue-linked pull requests (PRs) on GitHub. The work addresses three persistent challenges in scaling agentic software engineering datasets: low conversion yield due to dependency/build complexity, production of weak/easily hackable verifiers, and prohibitive computational cost when using large LLM-powered agents. The framework combines a custom-trained, efficient building agent with iterative self-verification and in-loop hacking detection, achieving unprecedented scale—over 800,000 multilingual, high-fidelity environments—substantially surpassing previous efforts in both quantity and cross-language diversity.
Figure 1: SWE-Universe's instance count is orders of magnitude higher than prior Python-only and recent multilingual datasets.
Framework and Key Methodological Contributions
At the core of SWE-Universe is an autonomous building agent employing the Qwen-Next-80B-A3B model, enhanced using a Mixture-of-Experts architecture and hybrid attention for efficiency and low latency. The build process includes the following innovations:
- PR Crawling and Patch Separation: Rigorous filtering for issue-linked PRs and automatic separation into test/fix patches using LLM classification, ensuring only tasks with executable verification potential are considered.
- Agent-Based Environment Construction: The agent builds environments by first applying test patches, then synthesizing a universal verifier script (evaluation.sh) that uses integer exit codes, explicitly decoupling reward logic from language-specific testing tools for maximum generalizability.
- Iterative Validation Loop: The agent self-tests its scripts on both buggy and fixed states, utilizing shell-based state toggling tools (switch-to-resolved/bug). Scripts failing reliability or coverage are revised in up to 100 agentic turns, significantly raising build success rates.
- In-Loop Hacking Detection: An LLM-driven module inspects verification scripts for shallow pattern-matching or grep-based hacks, preventing agents from revealing solution status via file diffs. Only scripts triggering true executable checks are retained.
Figure 2: SWE-Universe's construction pipeline combines agentic building, hacking detection, and iterative self-verification to ensure reliability and scale.
Evaluation scripts undergo strict functional criteria: only those genuinely exercising code logic are accepted (see Figure 3 for representative cases). Static pattern-matchers are flagged and rejected, ensuring verifiers deliver actionable agentic reward signals.

Quality Assessment and Dataset Analysis
Quality control extends beyond environment build success to dataset curation. A dedicated quality-judge agent—demonstrating 78.72% accuracy on human-labeled benchmarks—classifies task clarity, environment alignment, and verifier relevance. SWE-Universe achieves task quality on par with prior datasets (such as SWE-Rebench) but at nearly two orders of magnitude higher scale.
Figure 4: Task quality is maintained at scale, matching top benchmarks while providing orders-of-magnitude more samples.
Language distribution analysis reveals coverage patterns: Python and JavaScript dominate, Go environments exhibit high repository density, and C/C++ verifiers are the most complex in terms of script length.
Model Performance and Benchmarking
Qwen-Next-80A3, the backbone model, surpasses proprietary competitors (Claude-Opus-4.5, Gemini-3-Pro) on a comprehensive benchmark of PR-based task construction across eight languages, yielding a non-hacked success rate of 78.44%—a new state-of-the-art in automated environment generation. It also achieves the minimal hack-vs.-nonhack success gap, demonstrating robustness against superficial solution strategies.
Large-Scale Agentic Model Training
SWE-Universe environments enable high-volume agentic mid-training and RL for coding agents. Using Qwen3-Coder-480B-A30B and five agentic scaffolds, the team amassed 500K successful trajectories (30B tokens) for mid-training, with no loss masking to maximize agentic representation learning. Scaling trends are robust: SWE-Bench Verified scores rose from 50.3% to 61%, while SWE-Bench Multilingual surged from 31% to over 46%. Agentic RL using the pass/fail signals from evaluation.sh further drove Qwen3-30a3 from a baseline of 32% to 42% on diverse coding tasks.
On flagship deployment, Qwen3-Max-Thinking achieved 75.3% on SWE-Bench Verified, validating both the scale and utility of automated large-scale environment construction.
Practical and Theoretical Implications
The SWE-Universe framework offers several implications:
- Resource Availability: It provides the most extensive, diverse corpus of real-world, verifiable coding environments to date, supporting large-scale agentic training and evaluation for LLM-based coding agents well beyond prior Python-centric limits.
- Generalization Across Languages: The demonstrated scaling trend on multilingual benchmarks suggests that cross-lingual agentic learning is achievable through massive real-world instance exposure.
- Self-Correction and Robust Verification: Iterative agentic building with integrated hacking detection proves effective in producing reliable, reward-aligned test environments, raising prospects for agentic systems in other domains requiring executable environment construction.
- Efficient Model Design: Task-specific, fine-tuned MoE architectures exhibit superior reliability and cost-efficiency compared to larger general-purpose LLMs, suggesting specialization is crucial for scalable software engineering automation.
Looking forward, further research could incorporate adaptive verifier complexity, real-time data augmentation, and tighter integration with language-specific CI/CD platforms. Automated quality assessment agents and dynamic reward shaping for RL offer pathways to even more robust improvement.
Conclusion
SWE-Universe delivers a demonstrably efficient, scalable, and reliable automated environment construction methodology, setting a new benchmark in dataset scale, cross-language coverage, and verifier robustness. The framework supports both supervised and RL agentic coding models, with strong empirical results in benchmark performance and multi-agent training scalability. Its methodologically rigorous, resource-rich approach lays the groundwork for future developments in generalizable and trustworthy AI coding agents.

SWE‑Universe: A simple explanation
What is this paper about?
This paper is about building a huge, real, and reliable “practice world” for AI coding assistants. The authors created a framework called SWE‑Universe that automatically turns GitHub pull requests (PRs) into small, self-contained coding tasks that a computer can try to solve—each with a clear way to check if the solution actually works. They scaled this up to over 800,000 tasks across many programming languages.
What questions are the researchers trying to answer?
The team wanted to know how to:
- Collect tons of real coding problems from the wild (GitHub) and turn them into tasks that actually run.
- Make sure each task has a trustworthy “referee” (a test script) that checks whether a fix is really correct, not just faked.
- Do all of this fast and cheaply, so it can work at massive scale.
How did they do it? (Methods in everyday language)
Think of each GitHub PR as a “before and after” story:
- “Before” = the code with a bug.
- “After” = the code after a developer’s fix.
- Often, the PR also includes tests that show the bug is gone.
The authors’ system turns each PR into a small training gym for AI:
- Finding the right PRs
- They search GitHub for PRs that link to issues (the problem description) and include tests.
- They split the PR into a “test part” (what to run to check correctness) and a “fix part” (the code change).
- Building a verifiable task
- An AI “building agent” creates a standard test script called evaluation.sh. This script is like a referee: it runs the code and returns:
- 0 (success) if the fixed code works,
- non‑zero (failure) if the buggy code fails.
- The agent can either run existing tests (like pytest or Jest) or write a small new test when needed.
- An AI “building agent” creates a standard test script called evaluation.sh. This script is like a referee: it runs the code and returns:
- Trying, checking, and trying again (Iterative Validation)
- The agent flips the code between “buggy” and “fixed” states (like a light switch) and runs the script in both states.
- The script only counts as good if it fails on the buggy code and passes on the fixed code.
- If it doesn’t, the agent adjusts the setup and tries again. This loop boosts reliability a lot.
- Catching cheats (In‑loop Hacking Detector)
- Some scripts might try to “cheat,” for example by using simple text searches (like grep) to spot the fix instead of actually running tests.
- A built‑in “cheat detector” flags and rejects these shortcuts right away, forcing the agent to produce real, executable tests.
- Doing this at scale and speed
- They trained a fast, efficient AI model (called Qwen‑Next‑80A3) to power the building agent. You can think of it like a “team of specialists” (a Mixture‑of‑Experts model) that chooses the right expert for each job, making the process both strong and efficient.
- They deployed the system across many machines in the cloud, packaged results in Docker (so tasks run the same everywhere), and ran millions of builds in parallel.
- Measuring quality (Benchmark and Quality Judge)
- They built a benchmark to test how well different models create valid tasks across languages (Python, JS/TS, Java, Go, Rust, C/C++, C#, etc.).
- They also built a “quality judge” agent to rate task quality and filter out confusing or unreliable ones.
What did they find, and why does it matter?
Here are the main results and their importance:
- Massive scale, real data
- They built 807,693 runnable, verifiable tasks from 52,960 GitHub repositories, covering many languages—not just Python. This is far larger and more diverse than prior datasets.
- Why it matters: AI coding assistants learn better when trained on lots of real, varied problems.
- Stronger, more reliable building
- Their iterative validation raised environment build success from 82.6% to 94% on a test set.
- Their cheat detector stopped fake “tests” that don’t actually run the code.
- Their builder model (Qwen‑Next‑80A3) achieved the highest “non‑cheating” success rate (78.44%) on their benchmark, outperforming strong competitors.
- Why it matters: Reliable tests prevent AI from learning bad habits and make evaluations trustworthy.
- Better training for coding AIs
- Mid‑training (continued training on the new data) improved performance on well-known benchmarks:
- On SWE‑Bench Verified, scores climbed from about 50% to over 61% during training.
- On a multilingual version, scores jumped from ~31% to over 46%.
- Reinforcement learning (RL) with these tasks gave another big boost:
- A 30B model improved from ~32% to 42% on SWE‑Bench Multilingual.
- Their top model (Qwen3‑Max‑Thinking) reached 75.3% on SWE‑Bench Verified.
- Why it matters: These gains show the dataset provides clean, strong feedback that helps AI agents actually get better at real-world coding.
- High quality at large size
- A “quality judge” agent reached ~78.7% accuracy in checking task quality, and the dataset’s overall quality matches smaller, well-known datasets—even though this one is much bigger.
- Why it matters: You get both breadth and reliability, which is rare.
What’s the bigger impact?
- More capable coding assistants
- Because the tasks are real and span many languages, future AI coding tools can generalize better and handle more varied projects.
- Fairer, safer evaluation
- With robust “referee” scripts that truly run code, researchers can trust pass/fail signals and avoid misleading shortcuts.
- Faster progress for AI + software engineering
- A huge, verifiable training ground accelerates research in both supervised learning and RL for coding agents.
- The efficient, low-cost pipeline means others can build and iterate at scale.
In short, SWE‑Universe provides both the “stadium” (millions of realistic, runnable tasks) and the “referees” (reliable tests) that AI coding agents need to practice, improve, and be measured fairly—pushing the field toward smarter, more trustworthy coding tools.
Knowledge Gaps
Knowledge Gaps, Limitations, and Open Questions
Below is a single, focused list of what remains missing, uncertain, or unexplored in the paper, written to be concrete and actionable for future work:
- Dataset availability and reproducibility: The paper does not specify whether the 807,693 environments, Docker images, and evaluation scripts will be publicly released (with licensing) or reproducible outside Alibaba Cloud ACR. Action: Clarify release plans, licensing, and provide reproducible build artifacts and registry mirrors for non-Alibaba users.
- Verifier robustness criteria lack formalization: “Genuine execution” is enforced via an LLM-based hacking detector, but no formal, reproducible criteria are defined. Action: Specify rule-based constraints (e.g., mandatory compile and test execution, banned commands, allowed paths) and publish a standardized static/dynamic policy for verifier validation.
- Hacking detector reliability and coverage: The LLM detector’s false-positive/false-negative rates are unreported, and evasive patterns beyond grep (e.g., calling
switch-to-resolvedfrom evaluation.sh, git-diff checks, stubbing/mocking to force success) are not quantified. Action: Build a labeled corpus of hack patterns, benchmark the detector, and introduce runtime guards (sandbox policies, syscall auditing) to block common evasion classes. - Evaluation.sh permissiveness: It is unclear whether evaluation.sh is permitted to mutate repo state (e.g., toggling patches or editing tests). Action: Enforce a strict contract on evaluation.sh forbidding state toggling and write operations outside test artifacts; verify via filesystem change auditing.
- Lack of test coverage guarantees: There is no measurement ensuring verifiers execute the modified code paths (e.g., line/branch coverage of changed files). Action: Incorporate coverage tooling and require minimum coverage thresholds on lines touched by the fix patch.
- Flakiness and nondeterminism: The paper does not analyze test stability across reruns, machines, time, or network conditions. Action: Track flakiness rates, enforce hermetic builds (no external network), pin seeds and dependencies, and re-run verifiers multiple times to certify determinism.
- Patch-splitting accuracy: The LLM-based split of test vs. fix patches lacks error-rate estimates across languages and repository structures. Action: Provide a gold-standard benchmark for patch splitting, report accuracy by language/toolchain, and publish failure cases and fallbacks.
- Bias from discarding PRs without test changes: Rejecting PRs without a discernible test patch may skew the dataset toward projects with strong testing cultures, reducing representativeness of “real” maintenance workflows. Action: Quantify how filtering changes language/project distributions and introduce methods to synthesize high-quality verifiers for PRs lacking tests.
- Quality-judge agent validity: With 78.72% accuracy, this filter may admit or reject many tasks incorrectly, and its criteria are not fully defined. Action: Publish the rubric, per-language accuracy, confusion analysis, and human validation at scale; consider multi-judge consensus or hybrid rule+LLM adjudication.
- Sparse binary reward design for RL: The pass/fail signal is binary and may be sparse, yet no ablation on shaping (e.g., intermediate compile success, partial test pass) is provided. Action: Evaluate multi-signal reward shaping and its impact on RL sample efficiency and generalization.
- Data contamination controls with downstream benchmarks: Overlap filtering is claimed but not operationalized (no method for dedup across repos/issues/tests). Action: Release a transparent contamination audit pipeline that detects overlap via hashes, commit IDs, issue IDs, and test signatures.
- Cost, throughput, and energy metrics: Efficiency claims lack quantitative measures (cost per build, time per environment, energy/carbon). Action: Report standardized cost/latency/energy metrics for the pipeline and compare against baselines on identical hardware.
- Security, safety, and licensing: Running arbitrary PR code in cloud VMs poses supply-chain and security risks; licensing and redistribution of derived Docker images are unaddressed. Action: Document sandboxing, scanning (SBOM, CVE checks), license compliance, and responsible release policies.
- Long-term reproducibility and bitrot: The paper does not address dependency pinning, image longevity, or re-buildability as ecosystems evolve. Action: Pin dependencies, version base images, implement periodic rebuilds, and publish reproducibility checks over time.
- Cross-platform and OS coverage: The pipeline appears Linux/bash-centric; Windows/macOS build ecosystems are not evaluated. Action: Extend to multi-OS environments, measure success rates, and adapt tools for platform-specific builds (e.g., MSBuild, Xcode).
- Language/toolchain granularity: “Others” aggregates many ecosystems; the per-language difficulty and failure modes (e.g., Swift, Kotlin, PHP, Ruby) are not analyzed. Action: Provide fine-grained language-level breakdowns and tailor build heuristics per ecosystem.
- Verifier semantics limited to exit codes: Non-functional requirements (performance, memory, concurrency, latency) and partial credit (subset of tests pass) are unsupported. Action: Expand verifier semantics to capture non-functional metrics and weighted test outcomes.
- Component ablations are missing: The impact of iterative validation vs. hacking detector vs. model choice is not isolated with controlled experiments. Action: Run ablations by toggling components and report deltas in yield, quality, and build time per language.
- Scale-up failure analysis: ~24% of candidates fail to become non-hacked environments at scale, but causes and remedies are not detailed. Action: Categorize failures (dependency resolution, timeouts, missing build entry points, flakiness) and prioritize targeted fixes.
- LLM-generated custom tests vs. existing tests: The fraction of environments relying on newly authored tests (and their correctness/brittleness) is unknown. Action: Measure proportions, validate generated tests with human review, and assess stability and coverage.
- Benchmark representativeness and size: The 320-PR benchmark may be too small for robust cross-language conclusions; selection criteria and public release are not detailed. Action: Expand and release the benchmark with stratified sampling, ground-truth annotations, and reproducible harnesses.
- RL filtering of “too easy/too hard” tasks: Pre-filtering may bias training and evaluation results; criteria and effects are not reported. Action: Describe filtering thresholds, analyze bias, and compare RL performance with/without filtering.
- Generalization beyond the pipeline’s verifier style: Gains may overfit to evaluation.sh conventions rather than true task solving across unseen evaluation protocols. Action: Evaluate models on benchmarks with different verification paradigms (native CI, maintainers’ tests) and measure transfer.
- Ethical and governance considerations: The paper does not discuss notifications to maintainers/contributors, consent, or governance for large-scale PR mining. Action: Define ethical guidelines and governance for data curation from public repos, including opt-outs.
