PolyCodeEval: Benchmarking Multilingual Code Generation from Functions to Repositories

PolyCodeEval replaces fragmented single-language, single-granularity code benchmarks (e.g., HumanEval-style function-level sets) with a unified execution-based suite of 2,590 tasks from 58 real repositories across five languages, spanning function to repository granularity. The cost is substantial: running it requires reproducing 58 executable repository environments and execution-based evaluation infrastructure, which demands engineering time and compute beyond a single 24 GB GPU, likely requiring API access to frontier models for comparable numbers. It can fail as an adoption decision if the reader's production workload is single-language or function-level, where smaller benchmarks suffice, and rankings on it may not transfer to proprietary internal codebases.

For solo builders

A possible application for this research area. Paper-specific feasibility still needs a full-paper review.

An agent looks good in demos, but you cannot tell which product tasks it fails.

What you would change

Use the study's evaluation idea to inspect a small set of tasks with human-checked answers.

Use the study's evaluation idea to inspect a small set of tasks with human-checked answers.

Compare against

Your current evaluator and a manually reviewed reference set.

  1. Locate the paper's implementation and check its license, model support, data needs, and hardware requirements. Stop here if you cannot obtain the required artifacts.
  2. Save a small set of representative product tasks and expected outcomes. Keep evaluation tasks out of any training or tuning, and choose quality and cost limits before running.
  3. Run the baseline and the proposed change on identical inputs. Keep other settings fixed and repeat paired runs to expose variation.
  4. Save per-task outputs, failures, timings, and all usage costs. Review regressions before expanding the test.

What to measure

Agreement with human review, missed failures, false alarms, and evaluation cost per task.

When to keep it

Keep the change only if it meets your preselected quality and latency limits and improves the metric you care about after setup and operating costs. Otherwise retain the baseline. This is an exploration plan, not a validated recommendation.

Multilingual multi-granularity code generation benchmark

This is an evaluation benchmark rather than a deployable technique, so its value to a small team is workload-specific: useful only if they need multilingual, repository-level model comparisons before selecting a coding model or agent.

About the technical core

Equations have not been fetched yet.

When reading the methods, identify the rule, algorithm, or evaluation protocol that produces the claimed change. An equation is useful here only if it explains that mechanism.

  2. claim 02Paperraft inference

    Best evaluated methods generate at most 71.7%, 76.7%, and 31.0% correct functions, files, and repositories respectively, with wide variation across the five languages; no improvement factor is claimed for the benchmark itself.

    This is a Paperraft inference. It is not pinned to a verified PDF passage.

Editorial prompts, not findings from this paper or a validated test plan. Detailed analysis is still pending for the topics below.

What to inspect

Who grades the outputs? Inspect the rubric, disagreements, and whether the evaluator sees the method's identity.

Plan a fair comparison

Can you apply the same tasks and rubric to the baseline and candidate, then review disagreements by hand?

Questions for adoption

Are the results stable across prompts, languages, and task categories relevant to your product?
