FDE-Gym: The Last Mile of AI Delivery

Read the original on arXiv AI →

FDE-Gym is a new benchmark that evaluates AI agents on 95 end‑to‑end delivery tasks drawn from real customer scenarios across 18 sectors. Unlike traditional benchmarks that use well‑specified tasks, FDE-Gym places agents in simulated customer environments where they must clarify ambiguous requirements, interact with stakeholders, and uncover unstated constraints to improve a customer’s success metric. In tests, the best model configuration achieved a mean score of 0.56 and solved only 14 of the 95 tasks, highlighting a significant gap between well‑specified problem solving and real‑world AI delivery.

Can LLM Agents Be Forward-Deployed Engineers? Requirement Discovery and Delivery for Enterprise Text-to-SQL

The paper investigates whether large language model (LLM) coding agents can function as forward‑deployed engineer (FDE) agents by discovering customer requirements and executing deployment plans in a real enterprise text‑to‑SQL scenario. In a simulated engagement, agents must uncover acceptance criteria, data permissions, and hardware constraints before planning and delivering a post‑training recipe. Across 15 models, the best agents uncovered over 80% of hidden requirements, yet only 25% of runs met all acceptance criteria, revealing bottlenecks in discovery, execution reliability, compute usage, and benchmark relevance.

xDailyBench: Benchmarking LLMs on Professional Consultation for Real-Life Problems

xDailyBench is a new benchmark comprising 248 tasks across 51 real‑life scenarios, designed to evaluate large language models on everyday professional consultation. The tasks are based on actual user requests and assessed with detailed binary rubrics that capture both explicit instructions and implicit needs inferred from context. In tests of 11 leading models, the best achieved a 75.6% task‑level score, yet all models struggled more with implicit requirements, showing gaps of at least 9 percentage points.

$\tau^\tau$-Bench: An Environment for End-To-End, Realistic Agent Construction

The paper introduces $ au^ au$-Bench, a benchmark that turns the construction of AI agents into a measurable task. In this environment a developer agent receives real business records, client requirements, a production API, an existing codebase, and constraints on cost and models, and must deliver a complete customer‑service agent. The benchmark evaluates performance by deploying the agent against simulated users, revealing that current state‑of‑the‑art models achieve only 23.9% success while an expert‑written reference scores 82.2%.

ASI-Bench: At the Dawn of Artificial Superintelligence

ASI‑Bench is a new benchmark that evaluates AI systems on their ability to conduct innovative exploration and autonomous scientific research across 11 domains, using 60 project‑level tasks. It progressively removes human methodological guidance to test whether AI can independently select methods, execute research, and produce verifiable results. Results from 18 state‑of‑the‑art agent–model configurations show a sharp performance drop when guidance is reduced, indicating current systems still rely heavily on human input.
