DevQualityEval

An evaluation benchmark šŸ“ˆ and framework to compare and evolve the quality of code generation of LLMs.

This repository gives developers of LLMs (and other code generation tools) a standardized benchmark and framework to improve real-world usage in the software development domain and provides users of LLMs with metrics and comparisons to check if a given LLM is useful for their tasks.

The latest results are discussed in a deep dive: OpenAI's o1-preview is the king šŸ‘‘ of code generation but is super slow and expensive

Scatter plot that shows the best LLMs aligned with their capability on the y-axis to costs with a logarithmic scale on the x-axis of the v0.6 deep dive.

Installation

Install Git, install Go, and then execute the following commands:

git clone https://github.com/symflower/eval-dev-quality.git
cd eval-dev-quality
go install -v github.com/symflower/eval-dev-quality/cmd/eval-dev-quality

You can now use the eval-dev-quality binary to execute the benchmark.

Usage

REMARK This project does not execute the LLM generated code in a sandbox by default. Make sure that you are running benchmarks only inside of an isolated environment, e.g. by using --runtime docker.

The easiest-to-use LLM provider is openrouter.ai. You need to create an access key and save it in an environment variable:

export PROVIDER_TOKEN=openrouter:${your-key}

Then you can run all benchmark tasks on all models and repositories:

eval-dev-quality evaluate

The output of the commands is a detailed log of all the requests and responses to the models and of all the commands executed. After the execution, you can find the final result saved to the file evaluation.csv.

See eval-dev-quality --help and especially eval-dev-quality evaluate --help for options.

Example usage: Evaluate only one or more models

In the case you only want to evaluate only one or more models you can use the --model option to define a model you want to use. You can use this option with as many models as you want.

Executing the following output:

eval-dev-quality evaluate --model=openrouter/meta-llama/llama-3-70b-instruct

Should return an evaluation log similar to this:

The execution by default also creates a report file REPORT.md that contains additional evaluation results and links to individual result files.

Containerized use

Notes

The following parameters do have a special behavior when using a containerized runtime.

Docker

Setup

Ensure that docker is installed on the system.

Build or pull the image

docker build . -t eval-dev-quality:dev
docker pull ghcr.io/symflower/eval-dev-quality:main

Run the evaluation either with the built or pulled image

The following command will run the model symflower/symbolic-execution and stores the the results of the run inside the local directory evaluation.

eval-dev-quality evaluate --runtime docker --runtime-image eval-dev-quality:dev --model symflower/symbolic-execution

Omitting the --runtime-image parameter will default to the image from the main branch. ghcr.io/symflower/eval-dev-quality:main

eval-dev-quality evaluate --runtime docker --model symflower/symbolic-execution

Kubernetes

Please check the Kubernetes documentation.

Providers

The following providers (for model inference) are currently supported:

The Evaluation

With DevQualityEval we answer answer the following questions:

Programming is a non-trivial profession. Even writing tests for an empty function requires substantial knowledge of the used programming language and its conventions. We already investigated this challenge and how many LLMs failed at it in our first DevQualityEval report. This highlights the need for a benchmarking framework for evaluating AI performance on software development task solving.

Setup

The models evaluated in DevQualityEval have to solve programming tasks, not only in one, but in multiple programming languages. Every task is a well-defined, abstract challenge that the model needs to complete (for example: writing a unit test for a given function). Multiple concrete cases (or candidates) exist for a given task that each represent an actual real-world example that a model has to solve (i.e. for function abc() {... write a unit test).

Completing a task-case rewards points depending on the quality of the result. This, of course, depends on which criteria make the solution to a task a "good" solution, but the general rule is that the more points - the better. For example, the unit tests generated by a model might actually be compiling, yielding points that set the model apart from other models that generate only non-compiling code.

Running specific tasks

Via repository

Each repository can contain a configuration file repository.json in its root directory specifying a list of tasks which are supposed to be run for this repository.

{
  "tasks": ["write-tests"]
}

For the evaluation of the repository only the specified tasks are executed. If no repository.json file exists, all tasks are executed.

Tasks

Task: Test Generation

Test generation is the task of generating a test suite for a given source code example.

The great thing about test generation is that it is easy to automatically check if the result is correct. It needs to compile and provide 100% coverage. A model can only write such tests if it understands the source, so implicitly we are evaluating the language understanding of a LLM.

On a high level, DevQualityEval asks the model to produce tests for an example case, saves the response to a file and tries to execute the resulting tests together with the original source code.

Cases

Currently, the following cases are available for this task:

Task: Code Repair

Code repair is the task of repairing source code with compilation errors.

For this task, we introduced the mistakes repository, which includes examples of source code with compilation errors. Each example is isolated in its own package, along with a valid test suite. We compile each package in the mistakes repository and provide the LLM's with both the source code and the list of compilation errors. The LLM's response is then validated with the predefined test suite.

Cases

Currently, the following cases are available for this task:

Task: Transpile

Transpile is the task of converting source code from one language to another.

The test data repository for this task consists of several packages. At the root of each package, there must be a folder called implementation containing the implementation files (one per origin language), which are to be transpiled from. Each package must also contain a source file with a stub (a function signature so the LLM's know the signature of the function they need to generate code for) and a valid test suite. The LLM's response is then validated with the predefined test suite.

Cases

Currently, the following cases are available for this task:

Reward Points

Currently, the following points are awarded:

Results

When interpreting the results, please keep the following in mind that LLMs are nondeterministic, so results may vary.

Furthermore, the choice of a "best" model for a task might depend on additional factors. For example, the needed computing resources or query cost of a cloud LLM endpoint differs greatly between models. Also, the open availability of model weights might change one's model choice. So in the end, there is no "perfect" overall winner, only the "perfect" model for a specific use case.

How to extend the benchmark?

If you want to add new files to existing language repositories or new repositories to existing languages, install the evaluation binary of this repository and you are good to go.

To add new tasks to the benchmark, add features, or fix bugs, you'll need a development environment. The development environment comes with this repository and can be installed by executing make install-all. Then you can run make to see the documentation for all the available commands.

When and how to release?

Publishing Content

Releasing a new version of DevQualityEval and publishing content about it are two different things! But, we plan development and releases to be "content-driven", i.e. we work on / add features that are interesting to write about (see "Release Roadmap" below). Hence, for every release we also publish a deep dive blog post with our latest features and findings. Our published content is aimed at giving insight into our work and educating the reader.

ā— Always publish / release / journal early:

Release Roadmap

The main branch is always stable and could theoretically be used to form a new release at any given time. To avoid having hundreds of releases for every merge to main, we perform releases only when a (group of) publish-worthy feature(s) or important bugfix(es) is merged (see "Publishing Content" above).

Therefore, we plan releases in special Roadmap for vX.Y.Z issues. Such an issue contains a current list of publish-worthy goals that must be met for that release, a TODO section with items not planned for the current but a future release, and instructions on how issues / PRs / tasks need to be groomed and what needs to be done for a release to happen.
