Technology for scientific discovery

PhAI Labs' technical work turns on one question: how can AI systems take part in real scientific discovery. DFM is the research paradigm we propose for it; ScienceBuddy, ScienceIDE and JEPA-Anything are three independent research and engineering directions, working from interactive feedback, reusable scientific environments and world-state prediction respectively.

01Our technical direction

AI can already retrieve literature, generate code, process data and assist with parts of the research workflow. But discovery usually begins with a question that is not yet well defined, and advances through hypotheses, evidence, tools, experiments and continuous revision. That process cannot happen only on static benchmarks or closed tasks.

Intelligence has run out of internet. Published data is static and already trained on. What the frontier is short of is scientific data with a verified outcome attached: a hypothesis confirmed or rejected, an experiment that worked or failed. That data cannot be scraped. It has to be produced, inside real research.

So our direction is scientific intelligence itself: systems that keep learning, verifying and improving through real tasks and environmental feedback. Data trains the model; the model designs the next experiment; what comes back, including every failure, is the signal for the next round. This is why PhAI Labs works on foundation models, reinforcement learning, agents and scientific intelligence, and it is where DFM starts.

02DFM · Discovery Foundation Models

A research paradigm around Discovery Intelligence

DFM (Discovery Foundation Models) is neither a single model nor a software framework that forces every system through one pipeline. It is the research paradigm, capability definition and system organisation that PhAI Labs proposes around Discovery Intelligence: through formal definitions, process diagrams, system instances and real scientific cases, it turns “discovery” from a vague notion into a capability of model systems that can be learned, executed and evaluated.

Discovery Foundation Models, toward open-ended discovery intelligence: AI that no longer only solves the tasks it is handed, but takes part in the whole process of asking, testing and adding to what is known.

DFM is not a model, and not a software framework that forces every system through one pipeline. It is a paradigm, a capability definition and a way of organising systems: which capabilities the discovery process needs, how they connect, and where external evidence has to enter.

In this process, the scientific question comes first. Starting from a partially understood world, the system identifies a valuable unknown, turns it into a researchable problem, and builds hypotheses around it. A hypothesis does not stay on paper. The system calls research tools, data and experimental environments to act on it, gathers external evidence from analysis, experiments and expert judgement, and uses that evidence to confirm, revise or reject its own position.

Model training sits inside this process rather than in front of it. Every tool call and every experimental result is both a test of the model’s judgement and a training signal with a real outcome attached. Validated knowledge, reusable questions, tools and verifiers accumulate, and become the starting point for the next discovery.

Around this paradigm and capability definition, the research unfolds through system instances, independent papers, engineering modules and real scientific collaborations, released progressively. They do not add up to one fixed implementation; they explore, from different directions, how Discovery Intelligence becomes operational.

DFM takes an AI through a whole turn of discovery: find a question worth asking, test it against real evidence, keep what worked for next time.

Move the cursor over the diagram

The seven capabilities DFM is about

  1. 01

    Identify valuable unknowns

    Start from unexplained phenomena, places where methods fail, and anomalies in data, and judge which unknowns are worth pursuing.

  2. 02

    Turn unknowns into researchable questions

    Narrow a vague unknown into a bounded question with a way in and a way to check it, and state what would count as progress.

  3. 03

    Build and revise the representation

    Settle which objects, variables, relations, abstractions and structural constraints describe the problem; add a latent variable, drop a misleading proxy, or change the temporal or spatial scale and state the problem again.

  4. 04

    Build and revise hypotheses

    Propose hypotheses around the question, organize the existing evidence, and revise or drop a hypothesis when new evidence arrives.

  5. 05

    Call tools, data and experimental environments

    Take the hypothesis off the page: call literature, code, analysis tools and experimental environments, and turn judgement into actions that can be executed.

  6. 06

    Validate and update against external evidence

    Subject the system’s outputs to data, experiments, expert judgement and the physical world, and update its position according to what comes back.

  7. 07

    Accumulate reusable research structure

    Turn validated questions, tools, data and verifiers into reusable structure, so that each exploration becomes the starting point for the next discovery.

The DFM research-map repository carries the conceptual structure of the Discovery Loop, research directions, the open-source plan, demos and how to collaborate. Its directories and direction markers reserve future scope in public; they do not mean the corresponding implementations are finished or released.

03Three independent directions

ScienceBuddy, ScienceIDE and JEPA-Anything are three fully independent modules and research directions: independent in product form, usage, papers and implementation, with no required calls or dependencies between them.

ScienceBuddyAI research partner

An interactive Scientific Agent: recursive self-improvement in real research interaction, exploring Recursive-in-Recursive Self-Improvement (RSI in RSI).

ScienceBuddy is an independent research and engineering exploration built around interaction with scientists, research feedback and the continual improvement of agents, in the Discovery Intelligence direction DFM is about.

It focuses on an interactive form of Science RSI: a user poses a scientific question, the agent calls tools and answers; the scientist's follow-ups, edits, acceptances, rejections and re-runs become feedback that drives the research agent's workspace and harness to keep evolving.

What ScienceBuddy produces is not only one-off answers but the feedback, research trajectories, tool calls and task states of the interaction. In future these can be organised into reusable scientific tasks and environments for reinforcement learning or other model training.

An early product / research preview: the capabilities opened, demonstrations and entry points follow the actual version. The product entry opens on 16 September.

A scientist and an AI partner talk it through; every follow-up, edit and acceptance is written down, and the AI's workspace gets better round by round.

ScienceIDEScience integrated development platform

Infrastructure for scientific experience: real scientific code, tasks, environments and reinforcement-learning training.

ScienceIDE is an independent infrastructure exploration for real scientific codebases, research tasks and verifiable scientific experience.

It turns real scientific code, research procedures, task goals and verification criteria into scientific environments that run, measure and reproduce, so that researchers can do agent execution, model training and reinforcement-learning research in real scientific settings.

Its value is in organising real scientific software, domain judgement, task goals and verifiable feedback into one executable environment, an experiential base for research agents, model training, reinforcement learning and discovery research. ScienceIDE does not require ScienceBuddy to be used, and does not depend on JEPA-Anything to stand.

The project page, the technical report and the PhAI-IDE model weights are public. The models are trained on interaction trajectories verified in ScienceIDE, which remains open to task proposals.

Turn a real scientific codebase into a row of workbenches that run, get scored and can be repeated, so an AI can work on real scientific tasks and be checked.

JEPA-AnythingCross-domain unified science world model

A cross-domain unified science world model: cross-domain state prediction, intervention simulation and scientific diagnosis.

JEPA-Anything is an independent model-method study of latent world models and orthogonal predictive factorisation.

It explores how to learn latent representations that predict changes in world state, and how to offer one interface for intervention prediction, state synthesis and scientific diagnosis. The seven domains are vision, biology, clinical trajectories, control, molecular dynamics, physical fields and weather.

In the research vision, JEPA-Anything can be read as a unified predictive model or science world simulator over many scientific environments: when a researcher proposes an action or intervention, the model predicts the likely state changes, outcomes and risks in advance, helping screen out ineffective or costly plans. That is a direction to explore: today it does not simulate every scientific environment, and it is not connected to ScienceBuddy or ScienceIDE.

The technical report and the Hugging Face model collection are public; the scope follows their actual state. This release includes no public demo.

Predict before acting: if we do this, what does the world look like, and which option is worth taking.

Research questions

  • How to represent the many predictable factors of a complex system
  • How to predict the state changes different interventions bring
  • How to ground experiment selection and scientific diagnosis in prediction
  • How to reuse a latent world-state interface across domains

07A composable research path

A possible future path

Looking ahead, the three could form a composable research path: ScienceBuddy collects feedback and research trajectories from the interaction between scientists and agents; ScienceIDE organises that data and experience into reusable scientific environments for task execution, reinforcement learning and model training; JEPA-Anything explores unified state prediction and simulation across multiple scientific environments and interventions. That is a possible future combination, not an integration that exists today, and it does not change their independent standing.

  1. ScienceBuddy keeps interacting with scientists, producing feedback, task states and research trajectories
  2. ScienceIDE organises some of that experience into reusable scientific environments for executing, training and evaluating models
  3. JEPA-Anything explores unified state prediction over those environments and candidate interventions, so researchers can screen plans before acting
  4. Predictions and real experimental results return to the research process as new evidence

The path expresses the potential synergy of three independent works. It is not a completed integration, and it does not mean the three must merge into one system.

One module at a time

DFM is a paradigm, not a finished model. The research around it unfolds through system instances, independent papers, engineering modules and real scientific collaborations: on 15 September the DFM technical report and research-map repository go public; on 16, 17 and 18 September ScienceBuddy, ScienceIDE and JEPA-Anything are released in turn. Each project's links, code and product entries open on their day; anything that exists earlier is marked “coming soon”.

  1. Foundation Models

    Discovery Foundation Models: Toward Open-Ended Discovery Intelligence

    Ling Yang, Zhenfei Yin, Yingcheng Wu

    Foundation models have progressed from learning and reasoning over existing knowledge, to increasingly learning through action, tool use, and outcome feedback. We argue that the next frontier is a further transition: from solving and acting within problems specified by humans to participating in the process by which new problems, representations, explanations, and knowledge are created. We refer to this capability as Discovery Intelligence. We formulate Discovery Foundation Models (DFMs) as general-purpose model systems for open-ended discovery. A DFM operates over a revisable research state and supports seven coupled capabilities spanning problem discovery, formulation, representation construction, hypothesis formation, intervention, evidence-grounded revision, and continual discovery improvement. We instantiate this framework with Zetema, which couples explicit research-state dynamics, verification and experimental gating, external grounding, and cross-task Discovery Skill evolution. We further ground the framework with GALILEO, a real therapeutic-discovery system in which Dry-Lab reasoning, robotic and hands-on Wet-Lab experimentation, external biological evidence, and iterative hypothesis and design revision form a closed physical discovery loop. We then formulate a unified approach to capability formation and process-centered evaluation, enabling discovery behavior to be trained, improved, and measured beyond final-answer performance. Together, these components establish discovery as a learnable, executable, and evaluable capability of foundation-model systems. We view this shift as a broader progression in intelligence scaling: from learning over existing knowledge, to learning from action outcomes, and ultimately to participating in the construction, testing, and revision of the structures through which new knowledge is discovered.

    ScienceBuddy: Recursive-in-Recursive Self-Improvement for Interactive Scientific Agents

    Shuhan Xue*, Jianyuan Zhong*, Ziyuan Nan*, Wenbin Li, Zhaochen Yu, Jinchao Ding, Qiang Gao, Pengyu Zhan, Yuntong Zhang, Tian Cheng, Zhenfei Yin, Yingcheng Wu, Ling Yang

    ScienceBuddy is an interactive scientific research workspace that brings continually improving agents into a researcher's everyday work. It supports researchers in carrying out scientific tasks while turning their requests, feedback and execution evidence into tasks and evaluation rubrics for continual learning. At its core is recursive-in-recursive self-improvement, which couples harness evolution with model reinforcement learning: the inner recursion improves the harness with the model fixed, and the outer recursion trains the model under the improved harness. Case studies cover researcher interaction, harness refinement and model learning across four families of scientific task.

    ScienceIDE: Turning World's Scientific Codebase into Agent Learnable Environments

    Scientific code repositories encode decades of human knowledge in executable models, methods, and tools. Yet fragmented toolchains, implicit domain conventions, and specialized correctness criteria make this knowledge difficult to convert into reliable learning experience—a challenge we call the scientific experience bottleneck. We introduce ScienceIDE, infrastructure for turning the world’s scientific code into programmable environments for scientific agents. Guided by expert-defined scientific cases and acceptance criteria, agents transform repositories into executable environments that support task generation, execution, and scientific verification. These environments provide a shared foundation for supervised fine-tuning, reinforcement learning, and evaluation. Using verified interaction trajectories, we train PhAI-IDE-72B, PhAI-IDE-9B, and PhAI-IDE-4B. The model family shows gains in held-out scientific-code repair and across selected general-purpose benchmarks in code, reasoning, and knowledge, providing evidence of positive transfer from scientific experience to broader capabilities. ScienceIDE lays the foundation for an integrated workspace for agent learning and scientific practice, making humanity’s scientific software a shared substrate for developing scientific intelligence.

  4. World Models

    JEPA-Anything: Learning Predictive Models across Different Worlds

    Taoyong Cui, Zhongyao Wang, Xinyue Xu, Weiyang Liu, Zhaochen Yu, Yuying Zhang, Qiang Gao, Mengyue Yang, Wanli Ouyang, Pheng Ann Heng, Yingcheng Wu, Zhenfei Yin, Ling Yang

    World modeling enables intelligence to anticipate consequences, guide interventions, and learn from interaction. Yet predictive models remain domain-specific: can a common learning principle support world modeling across radically different systems? We introduce JEPA-Anything, a domain-agnostic framework based on orthogonal predictive factorization (OPF). Extending joint-embedding predictive architectures, OPF decomposes latent targets into complementary factors, learns them through dedicated pathways, and recombines them within a shared predictive design. We evaluate JEPA-Anything across seven domains: vision, biology, clinical trajectories, control, molecular dynamics, physical fields, and weather. Experiments span representation learning, intervention prediction, out-of-distribution generalization, and long-horizon dynamics, including 10 matched dynamics tasks, forecasting of over 1,000 clinical events, and 100-step molecular rollouts across four systems. Against matched JEPA baselines, JEPA-Anything improves reported metrics on all 10 dynamics tasks and reduces single-intervention prediction error on Interventional Pong by 34.8%. It achieves the lowest one-step and 100-step molecular errors among compared methods in all four systems. Beyond prediction, a factor-nominated biological intervention receives experimental support in cell co-cultures, patient-derived organoids, tumor fragments, and mice; latent orbital modes recover the Keplerian scaling exponent with a fitted slope of −1.4991. These results support a common factorized predictive principle across heterogeneous worlds, connecting world modeling with intervention and experimentally grounded scientific discovery.
