POSEIDON: Scaling Training Environments for Scientific Agents from Code Repositories

Read the original on arXiv AI →

POSEIDON is an automated pipeline that generates diverse, verifiable training environments from scientific code repositories, scaling up the number of environments by nearly tenfold compared to previous methods. It decomposes scientific workflows into four task types—Reproduction, Subflow, Completion, and Correction—to target distinct scientific research capabilities, and uses a recursive improvement loop to refine and recover environments. Using Poseidon, the authors created Pearl, a collection of 97,659 executable and verifiable environments from 7,110 public repositories across ten scientific disciplines, the largest multidisciplinary set to date, which enabled Qwen3.5 models to achieve consistent gains on six scientific-agent benchmarks.

D3-Gym: Constructing Real-World Verifiable Environments for Data-Driven Discovery

D3‑Gym is the first automatically constructed dataset that provides verifiable environments for scientific data‑driven discovery, comprising 565 tasks from 239 real scientific repositories across four disciplines. Each task includes a natural‑language instruction, an executable environment with pre‑installed dependencies, dataset previews, a reference solution, and an automatically synthesized evaluation script that achieves 87.5% agreement with human‑annotated gold standards. Training on trajectories sampled from D3‑Gym consistently improves Qwen3 models on ScienceAgentBench, and the platform also serves as a testbed for studying agentic optimization loops such as Autoresearch on real scientific workflows.

SAIL: Scientific Agentic Intelligence via a Science-Aware Loop

SAIL is an open model with 35 B total and 3 B active parameters designed for literature research, scientific coding, and multi‑step research workflows. It is developed through a science‑aware improvement loop in which agents built on frontier AI models analyze task failures, create training tasks to address capability gaps, and iterate this process across multiple development cycles. The training pipeline combines supervised fine‑tuning, specialist training, multi‑teacher on‑policy distillation, and agentic reinforcement learning, enabling SAIL to achieve competitive performance on scientific research tasks with fewer parameters than leading open‑weight models.
