Modal replicates Large Language Monkeys: LLaMA 3.1 8B matches GPT-4o on HumanEval via search

Modal's Charles Frye replicated the core claim of the Large Language Monkeys paper on a new dataset, showing that repeated sampling lifts LLaMA 3.1 8B from 66.4% pass@1 to 90.5% pass@100 and 95.1% pass@1000 on HumanEval, versus GPT-4o's reported 90.2% pass@1. The runs used vLLM on Modal serverless GPUs and Modal Sandboxes for parallel test execution, cost well under $50, and showed smooth, predictable scaling across three orders of magnitude.
