AI Coding Dataset NEW

SWE Long-Range Engineering . Warehouse-level generation . Contest-level dilemmas ..after training and preferences are aligned

For front-line demands for the 2026 coded model and code Agent, covering full spectrum tasks from single file restoration to several-sky marathon projects, the mission calibration is aligned to mainstream lists such as SWE-bench Verified/Pro, DeepSWE v1.1, FrontierSWE, LMArena Coding. Each type of data is accompanied by an enforceable environment, a calibration script and expert label, which can be used directly for SFT/RL post-training, alignment and competency assessment.

Dataset Catalog

Section Positioning and Development Value

Post-training fuel

Covers two types of SFT and RL post-training signals: a track of correct answers, a trail of failure and attribution, supporting algorithms such as DPO/GRPO.

Also on the list.

The training and evaluation are aligned with the assessment of the mission ' s profile lists, such as SWE-bench, DeepSWE, FrontierSWE, LMArena Coding.

Long-range capabilities

From single file restoration to inter-module re-engineering hours-sky task, which is dedicated to strengthening context maintenance, planning and mid-trip error correction capabilities.

Evaluation of infrastructure

Docker + Verify Scripts for certainty, and the client can repeat the results of the assessment by one key to avoid environmental and calibration disputes.

Data and Task Composition, Scale Description

Task Scale

Single-type missions, starting with 3,000-20,000, support the stratification and customization of the ease band (Easy/Medium/Hard/Frontier).

Language and repository

Python/Java/Go/ TypeScript/ Rust/C++ Six languages; warehouse-level tasks include complete scaffolding, unit testing and CI configuration.

Annotation Granularity

The task level rubric+ step track + code diff 3 is marked, which is training, attribution, assessmentable.

The DeepSWE head alignment model 65-73% resolution rate ranges; the Ultra Long-horizon pairing Zimarason list is very different.

Typical Use Cases

Post-coding model training

Complete process training for SFT/RL/Phosition to complete real engineering capability for the generic large model.

Encoding Agen Research

Capacity validation and short-board positioning for Claude Code, Codex, Opencode.

Benchmark Construction

A high-division, pollution-resistant private assessment set was developed for the evaluation agency and model manufacturers.

Model selection

To align the job set with the candidate model horizontally, output the selected conclusions that can be repeated.

Delivery Format and Specifications

Delivery Format

JSON/JSONL structured sample + code repository snapshot (with git history) + Docker task mirror + check script.

Core Fields

task_id、prompt/issue、repo_snapshot、gold_patch、test_patch、trajectory、rubric、difficulty、metrics。

Quality Control Standards

Double-reviewed note + automated script check + sample review, track replicability and label consistency are 98%.

Delivery Cycle

Standard 2-4 weeks; warehouse level and hyperlong range 4-8 weeks; support for batch delivery and rolling expansion.

Licensing and Compliance

Commercial use authorization + compliance review of open source agreements + sensitivity to sensitive information and provision of complete authorization documents.
