Can AI Code?

A self-evaluating interview for AI coding models.

Key Ideas

• Interview questions written by humans, test taken by AI
• Inference scripts for all common API providers and CUDA-enabled quantization runtimes
• Sandbox enviroment (Docker-based) for untrusted Python and NodeJS code validation
• Evaluate effects of prompting techniques and sampling parameters on LLM coding performance
• Evaluate LLM coding performance degradation due to quantization

5/6 Evaluate Qwen/CodeQwen1.5-7B-Chat (FP16, AWQ, Q8), openchat/openchat-3.5-0106-gemma (FP16), NousResearch/Hermes-2-Pro-Llama-3-8B (FP16).

5/6 Evaluate CodeGemma-7b-It (FP16, NF4, Q6_K_M) for instruction following, CodeGemma-2b and 7b for Completion and FIM (FP16, NF4, Q8).

5/5 Evaluate Phi-3 (transformers and GGUF) - there seems to be something wrong with the GGUF, even at fp16 performance is lower then transformers.

Test Suites

junior-v2 is a multi-language (Python, JavaScript) suite of 12 tests created for this project to test small LLM coding performance. This project provides all necessary components to execute this evaluation.

🚧 humaneval is a Python-only suite of 164 tests created by OpenAI. This project provides template scripts to prepare and execute the humaneval interview, as well as result extraction scripts to help their evaluator. See https://github.com/openai/human-eval for more information.

Results data

All model answers and evaluation results are now included inside this repository! Install a recent release of streamlit pip install streamlit==1.23 then streamlit run app.py or streamlit run compare-app.py to run the above webapps locally.

Results HumanEval

🚧 humaneval/ development work is currently paused, there's other projects that are much further along.

See https://github.com/my-other-github-account/llm-humaneval-benchmarks and https://github.com/abacaj/code-eval for large lists of Humaneval LLM benchmark results.

Repository Structure

Running on Modal

The recommended modal wrapper is interview_modal_cuda11.py which builds a CUDA11.8 based container with all the above dependencies working. An interview_modal_cuda12.py is also provided, but AutoGPTQ and CTranslate2 are not compatible.

Unfortunately the nature of Modal does not allow command-line selection of eitehr LLM model or runtime engine.

To select models, open the script and uncomment the .run_function(download...) line of choice. Note that only one model can be selected at a time. To add a new model, implement a new download... function.

To select runtime, open the script and uncomment one of the RUNTIME options. Note that for transformers you must also specify QUANT.

Question Format

A set of interview questions is a folder of .yaml files. Each Question is a top-level key:

SanityList:
    Signature: "things()"
    Input: "with no inputs"
    Output: "a list with three values: the number 5, the string 'foobar', the capital city of Spain"
    Fact: "the capital city of Spain is Madrid"
    Description: "List function, see if the model can combine input facts with internal knowledge."
    Checks:
        input_name:
            assert: "f.name"
            eq: "things"

In this example SanityList is the name of the interview question.

The first four fields are used by prepare.py to create the interview:

• Signature is the desired function signature
• Input describes the function inputs
• Output describes the function outputs
• Fact is optional and provides any context that is required to correctly perform the task

These 4 variables along with language (either python or javascript) are used to expand templates in prompts/.

The last two fields are used by evaluate.py to judge the results:

• Description is a human-readable explanation of why this test is useful
• Checks defines the expected behavior of the output.

Checks and the 'f' object

Each check has a name, some assert value (python code) and an expected eq value.

The f object represents the sandbox view of the function. Static analysis is performed on the function signature to extract the f.name and f.args fields, while f.call allows for function evaluation.

Output formats

All scripts output automatically named .ndjson files to the results/ directory.

Each stage outputs a super-set of fields from the stage before it, so its possible to feed eval/interview back to interview (to re-run the questions) or back to eval (to re-run the eval).
