Scientific collaboration supplies experience for improving both working procedures and the task model.
The science-buddy-preview release brings together two parts:
| What you can explore | |
|---|---|
| 1. ScienceBuddy for researchers | The scientific workspace, access information, a recorded demonstration and example research workflows |
| 2. Double-recursive RSI research | The open experiment code for improving a Python harness and task model through alternating learning stages |
ScienceBuddy brings researcher dialogue, scientific tools, execution records and analysis artifacts into a shared workspace. Its input and document workflows span multiple scientific domains, while the current tools and data specialize in biomedicine.
- Start with questions and material. Supply papers, tables, biological sequences or scientific images alongside a natural-language request.
- Connect claims to evidence. Ask the agent to inspect available data, retrieve literature and protein information, and organize findings and evidence gaps.
- Refine the analysis in conversation. Add another figure, narrow the scope or request a different comparison within the same task.
- Inspect the work behind an answer. Follow activity in Compute, explore the Trajectory, and examine tool inputs, outputs and generated artifacts.
The paper's workspace overview describes 224 tools across 22 functional modules, covering areas including genomics, molecular and cancer biology, pharmacology, bioimaging, literature retrieval and database queries.
Open ScienceBuddy Preview in your browser to explore
the scientific workflows below. The public web version is science-buddy-preview.
- Create a task. Start a new session or revisit a task in the sidebar.
- Add your material. Type a question and attach or paste the relevant figures, documents or data. State the output you need: an evidence table, study plan, comparison or explanation.
- Inspect the response and execution. Use Chat for the dialogue, Compute for activity, Results for artifacts and Trajectory for the event record.
- Follow up. Ask for supporting records, clarify missing information or change the scientific focus while retaining the task context.
Inspect a figure, trajectory and tool result
The paper illustrates how a researcher opens an uploaded diagram, switches to Trajectory and selects an earlier UniProt lookup to examine its input and output. English interface text is reconstructed from recorded interactions; uploaded scientific diagrams retain their original labels.

Watch a researcher upload scientific figures, inspect generated analysis and live tool activity, and continue the conversation with follow-up questions.

The example below is translated and abridged from the recorded interaction in the paper. It illustrates a workflow and reported observations, rather than a benchmark score.
Interpret a scientific figure and organize related evidence
Researcher request
Interpret this figure and organize the related knowledge in the data lake.
An immune-signaling diagram directs the analysis toward targets, drugs and pathways. The response organizes the findings into an evidence table and separates retrieved records from missing evidence: the paper reports a PDE4/rolipram fragment, while CD40 and AHR searches returned no matching records.
English UI and dialogue are reconstructed from the recording. The scientific figure retains its original labels; account and model identifiers are masked.
Scientific collaboration can reveal reusable lessons about how to approach the next task. ScienceBuddy's recursive-in-recursive self-improvement framework couples two learning processes: revise the harness that guides the agent, then train the model that acts through it. Each updated model participates in the next round of harness improvement.
| Inner recursion · model fixed | Outer recursion · harness fixed |
|---|---|
| Collect task interactions and feedback | Generate fresh on-policy task attempts |
| Propose Python harness programs | Score submitted answers with a verifier |
| Compare candidates with their parent on fixed Val tasks | Update the task model with SkyRL GRPO |
| Pass the selected harness to model learning | Return the exported model to harness learning |
Original method figure from the ScienceBuddy paper. Panel B details the inner harness recursion and outer model-learning recursion.
The paper figure includes adaptive task environments and online deployment. The experiment configuration here uses a frozen task release and sequential harness/RL stages.
The maintained experiment uses Qwen3.5-4B, a frozen 715 Train / 90 Val /
90 Test release, and three harness/RL cycles. Each harness stage has three steps,
16 training interactions per step and three candidate proposals. Each RL stage
has 30 GRPO updates. The harness exposes run(task, api); host code controls
execution budgets, grading and sampling.
These research experiments use bounded, verifier-assisted simulated feedback. They are distinct from the researcher-facing workspace demonstration above. Current configuration and stage measurements must be used when reporting this experiment; the paper's earlier case-study plots are not substituted for it.
Simple-SciBuddy (simple-scibuddy, imported as simple_scibuddy) is the
simplified agent implementation used by these RSI experiments. Its source lives
in src/simple_scibuddy/ and contains the experimental harness, execution broker,
verifier and SkyRL adapters. The full ScienceBuddy product source—including the
hosted workspace frontend, account system and product API service—is not included.
The detailed documentation follows the implemented learning procedure:
| Guide | Contents |
|---|---|
| Double-recursive RSI algorithm | Model/harness state, interaction feedback, candidate generation and selection, GRPO rewards and credit assignment, evaluation and stage handoff |
| Experiment guide | Current configuration, task split, execution budgets, setup, launch, continuation and recorded outputs |
Start with the algorithm guide to understand the two recursions, then use the setup and run instructions to reproduce the simplified experiment.
