It's positioned alongside benchmarks like SWE-Bench as a harder, more diverse test of agentic coding capability. Kimi K3 scores 67.5% as of July 2026. ## At a Glance **What it tests:** An AI coding agent's ability to resolve real-world software engineering tasks end-to-end — understanding a codebase, implementing a fix or feature, and verifying correctness. **Why it matters:** As SWE-Bench-style benchmarks approach saturation for frontier models, DeepSWE provides an independently curated task pool from DataCurve to cross-validate agentic coding performance. **Known limitations:** As a newer, vendor-curated benchmark, public documentation of methodology and task composition is limited compared to established academic benchmarks like SWE-Bench. ## What DeepSWE Measures DeepSWE evaluates coding agents on real-world software engineering tasks curated by DataCurve, a data-curation company focused on agentic and coding evaluation datasets. Tasks are designed to mirror the type of work a software engineer performs day-to-day — bug fixes, feature implementation, and refactors — verified against reference solutions or test suites. ## Benchmark Specifications | Field | Value | |---|---| | Task category | Coding agent | | Metric | % task success | | Saturation | Low | | Created by | DataCurve | | Dataset | [datacurve/deep-swe on HuggingFace](https://huggingface.co/datasets/datacurve/deep-swe) | | Project | [deepswe.datacurve.ai](https://deepswe.datacurve.ai) | ## How DeepSWE Is Scored Agents attempt each software engineering task and are scored on % of tasks resolved correctly, typically verified via automated test execution against the target repository. ## State-of-the-Art Results | Rank | Model | Score | Source | Date | |---|---|---|---|---| | 1 | [Kimi K3](/models/moonshot/kimi-k3) | 67.5% | [Kimi K3 technical report](https://www.kimi.com/blog/kimi-k3) | 2026-07 | *Score sourced from Moonshot AI's Kimi K3 announcement, July 2026.* ## DeepSWE on Benchgen > No Benchgen results yet — [be the first to run DeepSWE](/benchmarks/deepswe). ## DeepSWE vs Other Benchmarks | Benchmark | What it tests | Saturation | |---|---|---| | **DeepSWE** | Real-world software engineering agent tasks | Low | | [SWE-Bench Pro](/benchmarks/swe-bench-pro) | Professional-grade SWE agent tasks | Low | | [SWE-Bench Verified](/benchmarks/swe-bench-verified) | Verified real-world GitHub issue resolution | Medium | | [SWE-Marathon](/benchmarks/swe-marathon) | Long-horizon software engineering | Low | ## Run DeepSWE on Your Model Benchgen lets you run DeepSWE against your own coding agent, tracking task success rate over time to catch regressions from model or harness updates. ## Frequently Asked Questions
