    About Surge AI

    Surge AI supplies human-generated training and evaluation data for AI models, including RL environments, rubrics and verifiers, RLHF, SFT, and human evaluation. It also offers off-the-shelf datasets and enterprise programs for evaluating, improving, and training AI systems. Its site states a mission to raise AGI with the richness of human intelligence.

    What It Is

    Surge AI is a data and evaluation provider for AI model development. Its products page lists RL environments and agents, rubrics and verifiers, RLHF preference data, SFT demonstrations, human evaluation, expert professional domains, internationalization, multimodal data, and off-the-shelf datasets. The company says it works with experts such as doctors, lawyers, investment bankers, and academics, and operates in over 70 languages.

    Enterprise Evaluate, Improve, Train Workflow

    The enterprise page describes three tracks. Evaluate builds custom benchmarks and evaluation sets around a customer's workflows to compare models on quality, cost, latency, and reliability, validate before launch, and monitor production for regressions and drift. Improve diagnoses prompts, context, retrieval, tools, routing, grading logic, and agent behavior, then measures gains. Train designs programs using expert demonstrations, environments, rubrics, and preference data, covering supervised fine-tuning, reinforcement learning, preference optimization, and custom RL environments. Surge AI says pilot results arrive within a week.

    Benchmarks, Research, and Guides

    The site hosts benchmarks including the Tuesday Work Index, sudo L7, GDP.xlsx, DAYJOB: Healthcare and Finance, Chartography, HANDBOOK.md, Riemann-bench, and Hemingway-bench. It also publishes research and a set of guides on evaluating AI systems, choosing evaluation methods, comparing models, improving performance, and deploying and monitoring AI.
