How I combined 11 coding benchmarks without averaging incompatible scores

Reddit r/ArtificialInteligence Tools

Summary

The author describes a method to compare coding AI models by combining 11 benchmarks using percentile ranks instead of averaging raw scores, with a focus on de-duplication and weighted categories for 98 models.

I’m building LLMLearner and wanted a coding-model comparison that does not average incompatible raw benchmark scores. The current snapshot covers 98 model-series representatives, 11 qualified boards, and 268 de-duplicated model–benchmark results. Method: - Split evidence into repository engineering, agentic coding/tool use, live coding, and function generation. - Convert each recorded rank to a field-size percentile instead of averaging raw metrics with different scales. - De-duplicate overlapping tests; for example, HumanEval pass@1/pass@10/pass@100 cannot become three independent votes. - Weight the overall view 40% repository engineering, 35% agentic coding, 20% live coding, and 5% function generation. - Renormalize available weights when evidence is missing, while showing a separate coverage label. - Keep price, context, openness, and release status separate from the capability score. Known limitations: - Percentile ranks hide the magnitude of raw-score gaps and depend on the evaluated field. - Benchmark grouping and weights are editorial choices. - Agentic results include harness, tool, and scaffolding effects. - Public evaluations may be contaminated or over-optimized. - New and open-weight models often have uneven coverage.

Should local-deployment evidence such as quantization, VRAM, throughput, and long-context reliability become a separate dimension? Disclosure: I’m affiliated with LLMLearner.

Unsteady Metrics and Benchmarking Cultures of AI Model Builders

arXiv cs.AI

This paper introduces Benchmarking-Cultures-25, a dataset analyzing how AI model builders selectively highlight benchmarks in press releases. It finds a fragmented evaluation landscape with limited cross-model comparability, arguing that benchmarks are used as narrative devices for market positioning rather than standardized scientific measurement.

Are Performance-Optimization Benchmarks Reliably Measuring Coding Agents?

Hugging Face Daily Papers

This paper audits three performance-optimization benchmarks (GSO, SWE-Perf, SWE-efficiency) for coding agents, finding that runtime instability, scoring rules, and task coverage significantly affect reliability, and that many tasks are already solved by at least one public submission.
