README:
A brand-new, continuously updated SWE-bench-like dataset powered by an automated curation pipeline.
SWE-bench-Live is a live benchmark for issue resolving, designed to evaluate an AI system's ability to complete real-world software engineering tasks. Thanks to our automated dataset curation pipeline, we plan to update SWE-bench-Live on a monthly basis to provide the community with up-to-date task instances and support rigorous and contamination-free evaluation.
- 10/01/2026: We tested the performance of GPT5.2 / Claude4.5 / Gemini3 / DeepseekV3.1 with SWE-agent / OpenHands / ClaudeCode on our new SWE-bench-Live/Multi-Language benchmark. Please refer to our leaderboard for result. SWE-bench-Live Multi-Language Linux-Dist benchmark has been officially released, together with RepoLaunch that supports (C C++ C# Python Java Go JS/TS Rust) languages & (Windows, Linux) images. Merged into main. For old source code SWE-bench-Live/SWE-bench-Live (Python-only, the NIPS paper version), refer to python-only branch.
- 04/12/2025: We have updated eval result of GPT-5 and Claude-4.5 on our website. Though Claude might have seen the ground truth because its knowledge cutoff month is July 2025. We have also separated the RepoLaunch project to RepoLaunch. Please contribute repolaunch agent relevant codes to this new repository. For more info please refer to PR#35.

09/17/2025: Dataset updated (through 08/2025)! Weโve finalized the update process for huggingface dataset SWE-bench-Live/SWE-bench-Live (Python tasks): Each month, we will add 50 newly verified, high-quality issues to the dataset test split. The
liteandverifiedsplits will remain frozen, ensuring fair leaderboard comparisons and keeping evaluation costs manageable. To access all the latest issues, please refer to thefullsplit!
# Python >= 3.10
pip install -e .[!NOTE] Though this eval script has ensured backward compatibility with SWE-bench-Live/SWE-bench-Live (Python-only, the NIPS paper version), which uses swebench library for evaluation, if you want to evaluate on SWE-bench-Live/SWE-bench-Live (Python), for fair comparison we still recommend you to go to our old Python-only branch and follow the old evaluation method.
The below eval script is more suitable for our new datasets SWE-bench-Live/MultiLang and SWE-bench-Live/Windows.

If you would like to run our source code, please refer to Development.md.
In SWE-bench-Live, we propose an automated pipeline for curating SWE-bench-like dataset.
SWE-bench-Live Curation Pipeline
We addresses the bottleneck of setting up execution environments by automating the process through an LLM-based agentic tool โ RepoLaunch. It can deliver a testable containerized environment for any given GitHub repository, thereby enabling test-based evaluation in SWE-bench-Live.
We welcome external collaborators to help us create more SWE tasks each month, and improve curation and launch source code. Please contact [email protected]
Please feel free to raise issues and contribute pull requests to help us improve.
SWE-bench-Live is built upon the foundation of SWE-bench. We extend our gratitude to the original SWE-bench team for their pioneering work in software engineering evaluation benchmarks.

baml
BAML is a config file format for declaring LLM functions that you can then use in TypeScript or Python. With BAML you can Classify or Extract any structured data using Anthropic, OpenAI or local models (using Ollama) ## Resources  [Discord Community](https://discord.gg/boundaryml)  [Follow us on Twitter](https://twitter.com/boundaryml) * Discord Office Hours - Come ask us anything! We hold office hours most days (9am - 12pm PST). * Documentation - Learn BAML * Documentation - BAML Syntax Reference * Documentation - Prompt engineering tips * Boundary Studio - Observability and more #### Starter projects * BAML + NextJS 14 * BAML + FastAPI + Streaming ## Motivation Calling LLMs in your code is frustrating: * your code uses types everywhere: classes, enums, and arrays * but LLMs speak English, not types BAML makes calling LLMs easy by taking a type-first approach that lives fully in your codebase: 1. Define what your LLM output type is in a .baml file, with rich syntax to describe any field (even enum values) 2. Declare your prompt in the .baml config using those types 3. Add additional LLM config like retries or redundancy 4. Transpile the .baml files to a callable Python or TS function with a type-safe interface. (VSCode extension does this for you automatically). We were inspired by similar patterns for type safety: protobuf and OpenAPI for RPCs, Prisma and SQLAlchemy for databases. BAML guarantees type safety for LLMs and comes with tools to give you a great developer experience:  Jump to BAML code or how Flexible Parsing works without additional LLM calls. | BAML Tooling | Capabilities | | ----------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | BAML Compiler install | Transpiles BAML code to a native Python / Typescript library (you only need it for development, never for releases) Works on Mac, Windows, Linux  | | VSCode Extension install | Syntax highlighting for BAML files Real-time prompt preview Testing UI | | Boundary Studio open (not open source) | Type-safe observability Labeling |
